  1. Absent any other interaction, why would there be multiple paths for the photons?

     

    I didn't say anything about multiple paths. What I said was that if EM waves get blueshifted/compressed, but the flow of energy from the source doesn't increase, then the beam should fragment into multiple compressed pulses with breaks of some kind in between. This seems logical if you think of a certain segment of light as containing a certain number of waves within a given distance (say 1 million per meter to make it simple). Then if you blueshift that light to a shorter wavelength, the million waves cannot fill up the whole meter so I would think gaps would have to form at various points in that meter of light. Doesn't that make sense?

  2. I don't think theories ever get totally discarded in an absolute sense. Whatever it was that caused them to merit pursuit in the first place will tend to resurface in a new form. The more they failed, the more different they will look when they are resurrected. A lightly criticized theory will be modified and new avenues of research pursued. A "failed" theory will appear to be abandoned but aspects of it can be found in newer theories. A good genealogist of science could trace epistemological continuities across seemingly divergent theories, even when they are in very distinct disciplines.

  3. Unless you consider "maybe a house cat is a horse" an interesting statement to explore they aren't.

     

    Comparing cats and horses could involve different characteristics of each. What basis do you have to compare photons to gravitons, since gravitons are purely theoretical, as far as I am aware?

     

     

    This isn't the place for speculation.

     

    I did not bring up "gravitons" first in this thread. I was just playing off another post that mentioned them and considering a further theoretical possibility that they could be related to photons at the fundamental level of atomic construction/design. If particles always emit some level of radiation, why shouldn't they also be constantly emitting some level of gravitation? I'm not really trying to speculate as much as just considering avenues for how to explore possible relationships between gravity and light.

  4. My guess would be that when the memory starts to get triggered by a cognitive association, the emotional intensity of it emerging leads the person to supplant it with another thought or process. A person could start singing to themselves or even aloud, for example, to divert themselves from a memory or thought that is too intense to deal with. I believe this is why psychotherapy works to reduce the trauma of such memories and thoughts so that they can be expressed in a less intense way and therefore cause less distress and avoidance-behavior.

  5. I think the OP makes 100% sense. There is an avid BBT following for little purpose other than asserting denial of divine creation. Plus you have to think about the reasons people buy books: books are often presents to others or to oneself meant to symbolize something about the recipient's worldview or personality. How many people either wish themselves to display their belief in the absence of divinity or see this as a defining character trait in the personality of a loved one and wish to give them a book that recognizes that? It's a fairly cheap gimmick but they will surely cash in on it richly.

  6. I wonder if it would be possible to say that the least "evolved" organisms are actually the most fit. Sharks, for example, are supposedly very similar to the way they were a very long time ago. This is supposedly because they are so well adapted as predators that they have not needed to evolve further. The opposite could also be the case; that species that are evolving rapidly may be headed for genetic instability and thereby extinction. Humans are an interesting case because I have read that medical and other technologies have effectively stopped human genetic evolution, yet some people claim that this allows recessive genes to remain in the gene pool and spread, forming a risk for future expression. I wonder if you couldn't look at it another way, i.e. that by allowing recessive genes to continue several generations by treating their expression, other dominant genes are able to supercede them in meiosis and thereby prevent the loss of dominant genes with recessive genes that occur due to pre-reproductive deaths of individual organisms. In other words, it could be that preventing a recessive genetic characteristic from causing death prior to reproduction maintains greater variation and therefore stability among the dominant gene pool. Remember, no individual organism is devoid of good genes just because they contain a certain amount of bad genes. It's a waste to lose the good with the bad (baby with the bath water), no?

  7. ou see for me the method OF LOGIC that is science and by the way (I KNOW NOTHING I HAVE NO PAPER EDUCATION NOT EVEN HIGH SCOOL) BUT IN REWARD IM CURIOUS AND DARE I SAY not a slave to time and material gain lollVERY VERY BASIC Thermodinamycs, cosmology specttroscopy,geology biology HAVE BROUGHT A SORT OF MEANING AND BEAUTY (DARE I SAY SPIRITUALITY) TO MY LIFE.And now i found LOVE AND SHES CALLED PHILOSOPHY ( IM A SUCKER FOR WISDOM)

     

    Your post seems to address a great many divergent issues. If you really love philosophy, I would recommend burning your fuel in a more focussed way instead of going for a fireworks show. You could address any one of the issues you lumped into this big post as a thread discussion in itself. Once the thread gets going, you can always bring in related issues as they pop up in your mind reading what others have to say about your initial post(s).

  8. Whenever I hear about people going "muddin'" it seems like a good way to till a field for planting. In fact, when you see those images of people bathing in mud at woodstock, that also seems like a good way to till a field for planting. If you want to use your motorbike for tilling soil for planting, why not drive it around the field on a wet day, braking and skidding to tear up the grass or other ground covering? Then you can walk around and pull out the weeds you missed and plant seeds in the bare soil.

  9. I find it interesting and perhaps ironic that an object in frictionless motion does not perform work, yet it does traverse distance. In a sense the object is both "in motion" and "at rest" at the same time. This confounds fixed-coordinate spatial thinking, but it also suggests some reason to the fact that light can transmit power across a distance without performing work to do so; at least it does imo.

  10. I have learned from physics articles that the speed of gravity is equal to the speed of light. I'm just curious.., could light be the reason for gravity? If not, what is the reason for gravity? Just asking...

     

    Maybe "gravitons" are anti-photons. This is, of course, speculative but couldn't it be the case that as smaller particles fuse to form heavier ones, the energy released as radiation also generates a proportional amount of anti-radiation that remains in the form of mass/gravitation? Just as particles always emit a certain amount of low-level radiation, they may also consistently emit a certain level of gravitation, although I wonder why this level wouldn't fluctuate the way radiation-levels do, as a response to absorption and re-emission. Still, I wonder if gravitation could build up in particles in such a way that causes extremely large particles to decay faster. Maybe gravity-generation is very similar to energy-generation except mass has less volatility and dynamism in comparison with processes that store and release energy.

  11. Why didn't anyone build an atomic bomb or nuclear reactor before Einstein came up with the equation?

     

    To use mass conversion as the source of energy for the explosion, one needs to know that mass is a form of energy, and can be converted to other forms. Without that concept, nobody would bother pursuing it.

     

    Maybe the only reason anyone developed such a bomb is because they were afraid of the consequences of what it would mean for people to have access to unlimited energy. The fact that people react to power with fear and the desire to control power is not reason to blame the messenger. While some people reacted to the prospect of infinite energy with fear, others saw it as a road to peace and prosperity. If that ideology had dominated the reception of Einstein's claim, why would they have developed bombs instead of nuclear power plants?

     

    BTW, do you really find it legitimate to blame use of a technology on its inventors or developers? Do you think Karl Daimler or Henry Ford is responsible for all the deaths, injuries, and health problems caused by driving each year globally?

  12. good question about power plants. I think most would run out of fuel and the nuclear ones have automatic safety shutoffs that would stop them. Recent history suggests that deep ocean oil drilling rigs would continue to harvest oil until someone stopped the flow. Solar panels would keep generating electricity, as would windmills assuming their generators were engaged.

     

    The interesting question I would have with your scenario is whether people would all move together to a single city/community, or whether they would attempt to construct a new way of life with relatively few people in the cities they were in. Or would they become nomadic, roaming from place to place to consume what was left behind by all the disappeared people.

  13. I stand corrected Sisyphus. Yes, of course violet light has the shortest wavelength and that the sea is full of creatures :rolleyes: However, does the type of dissolved salt not also have an effect on sea colour?

    You can test your hypothesis by dissolving salt in water and observing whether its color or other reflection/refraction properties change. If you time your experiment well, you could follow it up with a pasta dinner or a nice soup. Have fun!

  14. Many people have often sought ways to phase through walls. Now for faster travel, Strategic advantage, Unissued access, or more mischievous reasons is unimportant. The want is there and where there is a will there is one hard headed enough to try.

     

    So the reason this topic has emerged on this wonderful morning at 2:00 am is as simple as my own curiosity. Last night (roughly at this time) I was watching the discovery channel about magnetism. When the topic of atomic magnetism came up I was immediately enticed.

    Learning that a spinning nuclei generates a tiny magnetic field only to be increased in force by the spinning electrons own magnetic field creates a small but, relatively strong magnetic field. Now among my constant quarries of the day this one unlike all others that had faded stayed bugging at the back of my mind. So I hand the torch to you, is it possible to demagnetize the atom thus since there is nothing to repel your own atoms rendering the wall / object penetrable?

     

    So it is magnetic force that causes objects to be experienced as solid? I always though it was electrostatic force.

  15. it makes sense that gravity would compress EM waves. The question is how those EM waves would remain intact and get compressed without the source velocity toward the target increasing. I would expect a high gravity target, such as a black hole, to blue-shift EM waves some but for those waves to fragment into multiple strands of compressed wavelengths. Is this presumptive?

  16. Of course, people could be let out of the structure, but if your thousands of storeys up, it would be pretty hard.

     

    if the structures were pyramid-shaped or long with sloping sides, there could be large open areas that would be accessible from the upper levels.

  17. I have often wondered how it would work to have multi-story greenhouses. You could put gardens around the edges of the building and have people living in the core. If you organized recreation levels, shopping levels, school levels, etc., I don't see why it would be inhospitable. Whoever posted that the heat would need to be ventilated in the winter may be thinking in terms of too much density. If there was a way to harness the heat while getting sufficient ventilation, it could be very efficient, I think.
