## What if you fall through space time?

No. Space-time should not be comprised of anything like dough. It is not substance-like at all. The concept of space-time is just the recognition that the measurements of space and time are frame dependent and not absolute. The analogy is that in Newtonian physics, space and time are treated like North/South vs. East/West. In such a situation everyone, no matter what direction they are facing, all agree on these directions. Everyone, for example, agrees that town A is 40 miles North and 30 miles East of town B. However the Space-time manner of treating this is that each person uses his own sense of Left/Right and Front/Back. Thus one person facing one direction will say that town A is 30 miles to the left of and 40 miles in front of town B, while someone facing in another direction would say that town A is 50 miles directly to the right of town B. It makes no more sense to think of space-time as being "substance-like" than it would to think of Left/Right-Front/Back as being "substance like". Now I also realize that in GR, it is said that Space-time "curves" in the presence of mass. And to many people this implies space-time being a "structure or substance". This is not what this means. "Curvature" of space-time really just means that the geometry rules governing it are non-Euclidean. In other words, the rules of plane, Euclidean geometry just don't hold.

## Idea for a rocket engine

I'll clarify for him. For the reaction mass to produce an upward force on the rocket, it has to be accelerated downward relative to the rocket. In order to return that mass to the top of the rocket, any downward velocity the mass has relative to the rocket has to be stopped and reversed. This is an acceleration just as much as the one producing the upwards force on the rocket (acceleration is either change in speed, direction or both). This action will exert a force on the rocket opposite to that caused by accelerating the fuel downward. The end result of this force will be counter any upward movement by the rocket. This ends up with the net movement of the rocket as being zero. There is no way around this. There is no "clever" way to "fool" the rocket into having net movement by recirculating the fuel/reaction mass.

## Resistance leads to mass and time in 3 dimensions.

This is yet another typical example of someone wanting to formulate a GUT with his personal model that has absolutely no idea what is involved in a GUT theory.... One of the most fundamental steps is the mathematics that offer a means of testing such a theory . A theory without mathematics that is based on simply verbal word play is utterly useless You cannot build a working circuit without being able to calculate the required resistance and capacitance to create an RC timing circuit. Nor can you predict how our universe will evolve in terms of expansion (which quite frankly required nearly every field in physics) nor can you make predictions of particle decay nor interactions You require mathematics for that.... This formula is far closer to a GUT than anything I have seen of your posts. $\mathcal{L}=\underbrace{\mathbb{R}}_{GR}-\overbrace{\underbrace{\frac{1}{4}F_{\mu\nu}F^{\mu\nu}}_{Yang-Mills}}^{Maxwell}+\underbrace{i\overline{\psi}\gamma^\mu D_\mu \psi}_{Dirac}+\underbrace{|D_\mu h|^2-V(|h|)}_{Higgs}+\underbrace{h\overline{\psi}\psi}_{Yukawa}$ You have absolutely no idea how detailed this formula truly is in terms of all the tensors/matrices complex conjugates etc. If you ever hope to build a GUT then you had best be able to decipher this equation. At the very least recognize each term Just for the record you have three spatial dimensions time is seperate as an independent variable which is the mathematical definition of a dimension. Hence spacetime containing four independent quantities that can change value without affecting any of quantity

## Psychiatry Does Not Exist or Should Not Exist

Obviously you never met somebody who really is paranoid. Not just vague ideas of being followed, but acting according these feelings, in such a way that such a person cannot copy with daily life anymore. Example: colleague comes panicking into the office, hiding immediately under his desk, saying that those helicopters outside are chasing him. Because that does not help. The paranoid feelings overwhelm a person completely, so he cannot think rationally anymore. That's why also very intelligent people can become psychologically ill. Intelligence does not protect against psychological illness.

## Given time, Intelligence is Inevitable

There is no purpose or goal in evolution. The purpose of a star is not to fuse hydrogen. The purpose of a river is not to send water to the ocean. What we observe in nature is a consequence of physical laws, there is no purpose. The basis of evolution is not improvement, that is too vague and subjective. Evolution is simply that an animal that is suited to an environment will survive long enough to produce viable offspring and one that isn't will not produce offspring. It may be that 200,000 years in the future man will have a brain that is only half the size that it is today. That would be an 'improvement' because that trait of having a pea brain is best suited for the environment.

## Does the expansion of universe effect light?

Yes...The expansion of the universe affects light and this is observed by the lengthening of the wavelength or shift to the red end of the spectrum, and is known as "cosmological redshift" The actual trajectory is affected by spacetime curvature or warping by intervening objects.

## The inconvenient truth about genetics

I appreciate you've though deeply about this issue - however this is incorrect. Regulatory genes can, for example, encode silencing mRNA which is used for post-transcriptional regulation of gene expression. RNA secondary structure can act to alter gene expression. Somatic V(D)J &nbsp;recombination of existing genes is critical for adaptive immune function. There is an entire field of Developmental Genetics which deals with the mechanisms for differential expression during development - and the vast majority are genetically determined. Ultimately, the genome does a lot more than simply encode proteins, and much of its less obvious function is newly and incompletely understood - the term "junk DNA" was coined in 1972 to describe the 98% of the human genome that does not encode proteins. It wasn't until the 1990's that we started to unravel the function of non-coding DNA, but it does a lot more than we originally thought and were are still in the process of determining its function.

## The inconvenient truth about genetics

I think you are just seeing the same issue from different perspectives. The DNA encodes required proteins (though again, it does not encode the required metabolites, such as nucleotides, amino acids etc, though it does encode the machinery involved in acquiring and synthesizing it), but it requires the presence of a fully functional cell background (with the machinery in place) to produce them. This is the chicken or egg problem as as without everything already provided by the cell (or having an incompatible cellular set up) the program will stall. Likewise, not providing required nutrient will inhibit the production of said machinery. I.e. if you nitrogen (or phosphate) limitation, translation/transcription will not proceed and it does not matter that the genome has all the information to produce all the proteins required for nitrogen/phosphate uptake. Plus there is increasing awareness that the cellular content plays an important role in the trajectory of cells, which might play an important role in asymmetric cellular aging. I.e. depending on what cellular component each daughter cell inherits (as the content is not necessarily divided perfectly equally), they may have different growth trajectories. So despite the fact that both cells inherit the same DNA, one may remain highly active, whereas the other one gets all the crap and heads to apoptosis. So yes, the basic genetic material is without doubt present and inherited within the DNA. However, its expression and the translation into a given phenotype is highly dependent on the intracellular (and extracellular) content.

## The inconvenient truth about genetics

I am wondering a bit why DanielBoyd got so many negatives on his OP. I think some people read it as another Intelligent Design posting, but it isn't. But as OP in a new thread, it is a bit long. Flying over it can lead to some wrong conclusions. But of course DanielBoyd is also to blame for this, given the title of the thread, and the, in my opinion, superfluous mentioning of entropy and its provocative title. For me it is clear that the DNA does not, and cannot, contain all information to build or even identify an organism (except of course by just comparing DNA of known organisms). It needs the complete apparatus of the living cell that the DNA can fulfill its function. A viewpoint one can use is that of a message and its interpretation. A message can only be interpreted by a correct interpreter. AFAIK the cellular 'interpreter' of DNA is not 'neutral'. Even if we had the complete DNA of some dinosaur, we will not be able to reconstruct how it looked like, because how the information is interpreted depends on what the dinosaur cell did with it. (So the Jurassic Park idea, to exchange frog DNA with dinosaur-DNA and so let grow a dinosaur, will not work, because the frog-egg has not the correct environment for the DNA to produce a dinosaur.) So I agree with DanielBoyd that DNA contains the design of an organism is not correct, even if DNA of course has a strong influence on what the organism will look like. It is more like a list of ingredients of a recipe. And of course there are all kind of feedback loops in the mechanism, where proteins synthesized according to a gen, has impact on what the cell does (directly or indirectly), and so possibly also on what genes will be read later on.

## A basic question about the big bang

This one. A few important things to note... The expansion of space only happens at very large scales. At the level of galaxies and clusters of galaxies, gravity stops things moving apart. The surface of a balloon comparison only works if you consider the just the surface of the balloon being a 2D analogy for 3D space. This also explains how a finite universe can have no boundary: the surface of the balloon (or the Earth) has a finite area, but has no edge. Dark energy is an extra factor that causes the rate of expansion to increase (this started about 4 billions years ago, I think) The speed at which things move apart is related to how far apart they are. This is nothing special, it is just because expansion is a scaling effect. Consider a number of galaxies separated by the same distance (far enough apart that the expansion of space is significant and the same between all of them). At time 0, they are 1 unit apart: A.B.C.D.E.F After some time they are 2 units apart: A..B..C..D..E..F After the same time again, they are 3 units apart: A...B...C...D...E...F And so on: A....B....C....D....E....F Now, if we look at the distance between B and C, for example, it increases by 1 at every time step. But the distance between B and D increases by 2 at every step. So the distance between B and D is increasing twice as fast as the distance between B and C; i.e. the speed of separation is twice as great. Choose any pairs of galaxies and you will see that apparent the speed of separation is proportional to the distance between them. Take two objects far enough apart and the speed of separation will be greater than the sped of light. (We can see galaxies that are receding faster than light.) We observe that (distant) galaxies are moving away.

## An Attack on Evolution; What am I getting wrong here?

There are a couple of wrong assumptions regarding genomic differences, but before that, a basic mistake is that your calculation assumes a genomic transition from human to chimpanzee DNA. However, the distance that you should calculate is that from either of them to their common ancestor, which diverged ca. 6 MYA ago. Another fundamental issue is that genome re-arrangements are not based on single nucleotide exchanges alone. Quite a lot of larger scale changes are based on duplications as well as deletions, predominantly in intergenetic regions. You will note that the genome size is actually different and if you align the whole genomes of the two species you will find sizeable gaps in either of them. So depending on how you actually count those gaps (and/or perform the alignment) you will find similarities between human and chimpanzees as low as ca. 80%. If we focus on actual genes, that shoots up close to 99%.

## Experiment to reveal parallel universe

Certainly not parallel universes. But if it provides evidence of mirror matter then it is possible (but not certain) that there could be large scale structures equivalent to stars and galaxies, made up of mirror matter. This would exist in our universe but not be directly detectable. That could be described as a "parallel universe" but it requires a bit of journalistic license. There is a good overview of mirror matter here: https://en.wikipedia.org/wiki/Mirror_matter

## Psychiatry Does Not Exist or Should Not Exist

If you would replace "does not exist" by "it is not true science"... i.e. "Psychiatry Is Not True Science, because [your reasoning here, about inability of scientific verification of person mental illness]".. your statement would have more sense and many more people could agree with it. If there is no reliability of source data, it's no different from reading from tea leaves, or numerology. Some people claim to find something/future in tea bags or leaves etc. Which is obviously false. I agree, there is needed MRI and other highly advanced scientific tools to check somebody hyper or lack of brain activity in certain regions of the brain and comparison with "normal"/"average" working brain (with lack of "reference brain" there must be used "average brain activity"). Medicament used to increase activity of brain if it's too low, other medicament to decrease too high activity (e.g. "psychoactive drugs"). Actually reactions of medicament on the brain, or reactions of hormones, or psychoactive drugs etc. etc. is quite well scientifically documented. There are routinely performed tests on animals, also apes, how they react on lack of, or abundance of certain drugs, and brain activities. You're now talking like people who are asking "when there will be cure for cancer?!".. i.e. it's lack of understanding, and putting everything to one single bag called "mental illness" or "cancer". Each person cancer is completely different from other person cancer. Each person has completely different mutation than other person (apart from obvious mistakes like transfusion or transplantation of organ from person with cancer to the new host etc.). There is nothing common in breast cancer of one women and other women, except placement of the cancer. Don't put them to one bag. Every case is unique. In one case it could be long term lack of chemicals required for normal brain work (improper diet missing essential compounds). In other case it could be attack of known or unknown parasites, fungi, microbes, which interfere with nervous system. In yet another case it could be genetic mutation. etc. etc. f.e. there are fungi which are attacking nervous system of animal like https://en.wikipedia.org/wiki/Ophiocordyceps_unilateralis and ant is starting behaving abnormally.. Reaction of human nervous system on presence of parasites is not yet fully understood. Especially for unknown parasites. Lack of high level technology equipment in psychiatric hospitals don't help. There used to be cases when somebody had tumor in the brain, and psychiatrists claimed they have some mental illness..

## Carl Sagan on Alien Life

Carl Sagan once argued about the improbability of aliens having visited Earth. He cited two main reasons: 1. the vast distances aliens would have to travel to get to Earth would be an almost insurmountable obstacle 2. the vast amount of time that separates civilizations during their rise and fall would make it unlikely that any intelligent civilizations would exist simultaneously On the other hand, Sagan has argued that he believes alien life is inevitable due to the vast numbers of planets and star systems that exist in the universe; he just doesn't think that intelligent beings have visited Earth, for the aforementioned reasons. I propose a counter argument. First, to agree with Sagan's general view of extraterrestrial life, the vast number of stars in our own galaxy alone makes it likely that some form of life does exist. These star systems undoubtedly contain billions of viable exoplanets. Even in our own solar system, planets such as Mars have been found to have water, and Europa, one of Jupiter's moons, is thought to have subterranean frozen seas. Is our own planet special? Probably not. Second, Sagan's point that civilizations would exist at different intervals, divorced from one another over eons of time, assumes one thing: that all intelligent civilizations would behave like Earth's. That is, all civilizations would rise and fall, as those on Earth do, and would eventually end in extinction within a relatively short time. But what if this isn't the case? What if other intelligent species establish equilibrium or harmony on their planet and can exist indefinitely, through the wise marshaling of resources and lack of egoistic competition? Why should we assume that all intelligent civilizations behave as haphazardly and ignorantly as human civilization does? Continuing this idea, if another species did reach evolutionary equilibrium, where it continued to progress technologically (and perhaps biologically also) but without inter-species conflict or discord, then that species could theoretically exist indefinitely - for hundreds of millions of years, (barring the lack of some existential catastrophe like a meteor strike). Further, if the species was continuing to develop technological as human do, then their capability for traversing the vast distances of space would exponentially increase also. With each passing milenia of stable progress an intelligent alien species would be more equipped to traverse the galaxy. It has taken human beings roughly 250,000 - 300,000 years to progress from a nomadic state to that of (limited) space explorers, but what would our technology look like if we steadily progressed without self inflicted anihilation for another 250,000 years? So the idea that an intelligent species could only exist for a short time is an assumption I don't think is 100% true. And IF that species is able to progressively develop their technology over eons without interruption, then who is to say that the vast distances of space would be any barrier? Additionally, how many star systems are there in our galaxy alone? Dr. Sten Odenwald, astronomer for NASA, writes in the Huffington Post that there are between 100 billion and 1 trillion stars in the Milky Way. At least 100 billions star systems, right in our own galactic neighborhood. Finally, there is the fact that the Earth is 4.5 billion year old, and has been inhabitable (with breathable air, water, and a viable food source) for 650 million years. Given these time frames, an alien species could definitely have evolved enough to venture out to explore its neighboring star systems and could have visited Earth already. So, while I agree with Sagan's view that alien life is more or less inevitable, I don't think that vast time or distance necessarily negate the possibility of aliens having visited Earth. Thoughts?

## Why dont we imprison people who dont respect different races and cultures

You need to be more specific. What do you mean by "not respecting different races and cultures"? I don't know where you live, but in a secular democracy where individual liberty is paramount we don't imprison people for not respecting other races/cultures. The concept of disrespect is entirely subjective and within the ego of the offended. And in the West we don't trample individual liberty for the sake of someone else's wounded ego.

## The inconvenient truth about genetics

Full ack. With 'authority' comes responsibility. In this case, to show where somebody is wrong. If the person in question does not react on that, then OK, leave him/her with his/hers ideas. So this is pretty useless: This neither advances discussion, nor teaches anybody anything. 'Citation please' can be useful when somebody claims that 'science has shown that...' followed by a crackpot idea. But I do not think the OP did that. He pretty clearly shows his ideas, and the experts between us can look if these ideas match present science, and when not, can show this (with citations, if necessary). Citations are necessary when we do not agree on the facts; on theories, i.e. interpretations of facts, we must discuss. Above has nothing to do with any advancement in insight from anybody, but only about 'winning a discussion'.

## Discussable Topics

We ALWAYS run the risk that some folks may not get to throw in their 2 cents when we close a thread. In the Tyson thread, the OP was over-emphasizing Tyson's stance from a debate where he was asked to pick a side to defend, and when this was pointed out it made no difference to his agenda. I'm sorry to be blunt, but when I'm moderating, I really could care less about any of you individuals posting to any individual thread. It doesn't even enter into my mind when I see the opening poster unveil a shit-stirring agenda, or post fallacious arguments over and over, or any one of a hundred things people do to get their threads closed. You getting a chance to comment isn't a factor. My job is to enforce the rules. Contact the Admins if you feel I should be replaced. As far as religion goes, It's against the rules to bring it up in mainstream sections. Should this be changed? Or should we be like other science forums and drop religious discussions altogether? I don't think discussing religion is analogous with unfalsifiable science subjects. When people start posting 30,000+ versions of the many worlds theory, each insisting they have the only true explanation, I may change my mind. What makes it interesting, MigL? It seems like an excuse to criticize and accuse others of being thin-skinned, while holding yourself up as scientifically virtuous. And since you also state that you'll never start a religious thread, it also seems like more shit-stirring. It's not even something you're interested in. Senseless?! I'm not paid enough to deal with your condemnations. Just because you didn't get to comment doesn't give you the right to bash my reasoning skills. It's great that you can judge us based on partial information. I'm probably too senseless to do that.
