1. ## Scalar and Takyonic force fields agains electronic mind control

And I would suggest not to quote a complete posting... What I would do:
2. ## The spacetime interval versus a chain of causative events

I think there are many ways to see c (do not pronounce that sentence). Just to mention a few: speed of light in vacuum speed of gravitation the speed limit of every object with mass the only speed massless particles can have maximum speed of causality the conversion factor between time and space, so that they can be used on equal footing Surely you could draw a spacetime diagram with another speed as conversion factor (you need it to get a distance, as you can only 'make distances' on paper). However for calculations you would still need c, and if you would like to derive formulas from the diagram, they would be awfully complicated. The Minkowski diagram, with c as conversion factor show everything much more directly. This might be a bit over-precise, but I would have written something like 'was historically (or originally) derived'. Logically seen, the values of e0 and µ0 'must adapt' to 'the only speed massless particles can have', not the other way round. Maxwell took 'the empirical way' based on Faraday's results, and so was the first to derive c, however without knowing how fundamental c is for the structure of spacetime. And that is why I like the last description of c best.
3. ## A Computational Theory of The Universe

Eh? I thought QED describes perfectly how bosons and fermions interact? And there is no empirical evidence that the brains 'special capacities', namely to create a mind, are mandated by quantum processes. That is not Occam's razor. Occam's razor is about explanations, not about nature. 'Explanations' are the ways humans understand nature. It is a heuristic principle for choosing possibly best theories: if you have several theories that explain the same phenomenon, then the theory that presupposes the least of number of ontological entities is probably the correct one. Do not forget this 'probable': Occam's razor is far away from 'dictating' anything, not even a rigid principle for choosing 'the correct theory'. Nice, but it does not mean that sciences are therefore wrong. It only means what it says: that many scientists are not aware of the philosophical presuppositions of their science. I cite it, because of the disdain many scientists have for philosophy: it is not meant as an invitation to propose new, wild, freewheeling, metaphysical speculations.
4. ## A Computational Theory of The Universe

So what is the relation between a neural firing rate somewhere between 1 - 200 firings per second (how many depends among others on what the part of the brain where the neurons are localised are active), and the translational speed of light? 300,000 km/s? Or should I express it as 300,000,000 m/s? Or 300 Mm/s? What has a clock frequency to do with a speed?
5. ## The predominant color of the flora and plant organisms of a planet in relation to the type of star it orbits and the wavelength it generates.

I think you can rule out O and B type stars. They live too short that life on a planet orbiting such a star can develop:
6. ## The Beginning of the Universe

Interesting, I've never heard of Yeshu but you would need to start another thread to explain it to me. Not needed: 'Yeshu' is just the (possibly) original name of Jesus in Arameic. Yes. In those days astronomers did not even know that other galaxies existed. They assumed that the universe on grand scales did not really change, and therefore had no beginning. When Einstein discovered, when applying his general theory of relativity to the cosmos as a whole, that the universe could not be stable, but had to expand or shrink, he introduced his 'cosmological constant'. Later Edwin Hubble discovered first that the spirally 'nebulae' were other galaxies on their own, and later that galaxies were receding from ours, the farther ones receding the fastest. Lemaitre was the first to propose, based on Einstein's general theory of relativity, that all the mass and energy of the universe once was concentrated in a 'cosmic egg'. This was not generally believed, and e.g. Fred Hoyle proposed the 'steady state theory', in which the universe is expanding, but that constantly new matter and energy is created, so that the universe does not really change on the grand scale. He coined the term 'Big Bang' to ridicule the idea that the universe started in a highly concentrated state.
7. ## Why use the atomic bomb on Japan?

At least for Pakistan I know the answer. Abdul Khan was a Pakistani who worked at Urenco in the Netherlands in the 70's. This company built ultracentrifuges to enrich uranium. Back in Pakistan, they were able to build them themselves. The greatest technical obstacle for building a bomb is not to construct a bomb, but the capacity to enrich uranium enough for the bomb. Really? So poor that they always already had to import their food? Don't do so ridiculous. @zapatos is perfectly right in his reaction. For modern technologies you might be right, but not for producing their own food. I would suggest, instead of just venting some opinions based on a few (alternative...) facts, read some books about the history of WW-II and about the development of the atomic bomb. Your posts show a gigantic lack of knowledge about, and understanding of history.
8. ## nonstop barrage of full page ad walls

I use the browser 'brave', when on Windows. I see no advertisements at all. 'brave' is a fork from Chrome, but specially written to block as much advertisements and pop-ups as possible. Pity enough this browser does not exist for Linux. With Chrome on Linux I see an awful lot of advertisement.
9. ## The Official JOKES SECTION :)

Leibniz. See Leibniz–Newton calculus controversy.
10. ## Why use the atomic bomb on Japan?

Well, it is a replica. You wouldn't like to visit in a cellar with a lot of radioactive material literally hanging around. AFAIK the Americans dismantled the experimental reactor, and took it to the US. The idea of the reactor was of course to lower the 'fission cubes' into the heavy water in the tank below it. If it really worked I do not even know. There are several not so nice stories about the heavy water. It came from a factory in Sweden. One time the English sent a commando in order to sabotage the plant. They succeeded, but damage was repaired in due time. And then there is the sinking of a ship to transport the heavy water from the plant. It was a sabotage act by the Swedish resistance. Innocent civilians were also on board, and drowned.
11. ## Why use the atomic bomb on Japan?

Wow, so much to unravel here. Yes. The scientific background was in the open. So it would be just a matter of time. And then the point Swansont mentioned: That is true, more or less. But Japan simply did not capitulate. So the war could have taken much longer, taking many lives of American soldiers. Yes, but only after Germany was defeated. Heisenberg was in charge. The infamous meeting between Heisenberg and Bohr in 1941, gave the latter the impression that the Nazis were making serious work of the atomic bomb, and brought this impression to the US. Yep. I have seen the 'atom cellar' in Haigerloch: Does not quite compare to Los Alamos, is it? I would not put my hand in the fire for this, but it surely was a reason: Truman said something like this about the Soviets and the atomic bomb: "Now we have a real hammer on those boys". Another reason might have been to have a 'real live test'. A hint for this is the second bomb. One of the A-bombs was a U-235, the other a plutonium bomb. Wouldn't it be interesting to compare their effects 'in the field'? About the capitulation of Japan: there was a struggle between the civilian government and the military. The government wanted to give up, the military wanted to fight until the bitter end. One of the struggling points was the position of the emperor. The US wanted an unconditional capitulation, the Japanese government found that the position of the emperor could not be discussed. In the end the Japanese government made a very unusual proposal: let the emperor decide. In the meantime the first atomic bomb was dropped. If this fact had an influence on the decision of Hirohito is not known, fact is that he chose to capitulate. His speech in which he called for the capitulation was recorded, to be brought to the Japanese radio studios. Radical militaries tried to steal the recording on its way to the radio station, but they did not succeed. Hirohito's speech was broadcasted, and Japan capitulated. And the US more or less let the emperor untouched. Had the US made it known that the emperor could stay earlier, Japan might also have capitulated earlier. Maybe the A-bombs would not have been necessary. Main source: Bert Röling, who was a.o. member of the International Military Tribunal for the Far East (also called the Tokyo Tribunal, similar to the Nürnberg Tribunal in Germany). Hmmm. Lise Meitner and Otto Frisch were hardly Nazis, they were Jewish and fled Germany in 1938. Otto Hahn: Fritz Strassmann: So four of the 'main characters' were definitely not Nazis. Equating 'German' and 'Nazi' is simply wrong, also during WWII.
12. ## What is gravity?

Nicely put. I also do not know of masses that do not have a gravitational field, resp without 'curving' spacetime. And that is an important reason for me not to see a causal relationship between mass and curved spacetime.
13. ## Second time I'm unable to contribute.

Hi Naitche, I sometimes have such kind of problems too. For me a reload of the web page helps. Maybe you too? Cheers, Eise
14. ## Mind-brain (split from I ask recognition from physicalists of at least 1 non-physical dimension where concepts, the inner voice, inner imagery and dreams 'reside'

Just as a side note: 'without examination' does not mean necessarily 'wrong'. It means for me that even in the 'hard sciences' there are philosophical assumptions, that even (some?) scientists might not be aware of. I chose this disclaimer because of the disdain that scientists often have of philosophy. Don't be afraid: philosophy is much harder with pseudo science, quasi scientific speculations, free riding ideas with no basis on (observable) reality, or metaphysical fantasies.
15. ## What is gravity?

Hmm. I don't think naming it a cause, and even a mechanism, is a good way expressing the relationship between mass and spacetime curvature. In my opinion that would mean that physics would be able to describe the mechanism, and that implies new laws of nature. I think that we recognise mass because of its curvature (or inertia). Nobody asks for how a charge 'causes' an electrical field. So why should one do it for a gravitational field, even if we now know that this field is a geometrical curvature of spacetime? So if these are the only two possibilities, I opt for option 1.
16. ## Mind-brain (split from I ask recognition from physicalists of at least 1 non-physical dimension where concepts, the inner voice, inner imagery and dreams 'reside'

Really? Bold by me. If a 'scientific article' cites Deepak Chopra as serious witness, then it is not serious scientific article. Maybe you should read Susan Blackmore: in her student days she had an OBE, and she started a career as 'believing' parapsychologist. But her serious empirical investigations turned her into the end being a sceptic, and leaving the field of parapsychology. I can highly recommend Dying to Live: Science and the Near-death Experience and The Adventures of a Parapsychologist. From the Wikipedia article:
17. ## I ask recognition from physicalists of at least 1 non-physical dimension where concepts, the inner voice, inner imagery and dreams 'reside'

Yep. The mind is an activity of the brain, just as a whirlpool is an activity of water. Or, @Maartenn100, is there a separate (physical?) space for whirlpools?
18. ## I ask recognition from physicalists of at least 1 non-physical dimension where concepts, the inner voice, inner imagery and dreams 'reside'

Ah, Descartes 1.1. 'Res extensa: 3 spacial dimensions. 'Res cogitans': mind. Calling it a dimension is just obfuscating method of hiding substance dualism. 'Substance dualism', because something has to exist in this 'dimension', otherwise it is just empty. Nope. To use your metaphor: our mind is a whirlpool in the brain, not in your imaginary dimension.
19. ## How do scientists explain RF waves traveling, without a medium?

Yes. And? If you want to stick to old fashioned meanings then physics is philosophy. Newtons 'Principia' is clearly a work of philosophy: it is even in the complete title. So. Can we just look what is done under the header of 'philosophy' in academia today? Or maybe I do not even understand what you are trying to say.
20. ## How do scientists explain RF waves traveling, without a medium?

Philosophy is not a pseudoscience. Yep. Philosophy is not even science. It is reflection on how we think, being it on the subject of politics, ethics, or ... science. See my disclaimer.
21. ## Curiosity on the relationship between matter and energy

I would say even stronger: it is the factor needed to put space and time on the same footing. So to speak, the 'exchange rate between space and time'. This 'exchange rate' determines the causal structure of spacetime. It leads necessarily to the fact that there must be a maximum speed with which events can be causally related. Particles with mass can never reach this speed, as it would need an infinite source of energy. On the other side, massless particles can only travel at this speed. Thus the speed of light is not 'the speed of light': it is the speed of all massless particles. So the answer is: if the causal structure of your alternative universe is the same as ours, then the same relationship holds.
22. ## Your thoughts on Islam?

Just a side note: not 'centuries'. The latest gospel written was that of John, and historians estimate that it was written around the year 100 CE. I always supposed that Mohammed was much more historical than Jesus. The merchant being his uncle, such stuff. But maybe I have to correct that opinion. And was Mecca not already a place of religious worship: there stands the Kaaba, which is older than Islam. Could that have been a reason to conquer Mecca, to seize power over this important religious symbol?
23. ## Future of quantum computing

It depends on the application, if a quantum computer is really faster than traditional digital computers. So if computers with enough qbits can be realised, some kinds of calculation will be much faster. But it is a big 'if'. I am afraid, quantum computers will go the same way as nuclear fusion reactors, unless some stable 'room temperature' realisation of qbits is found. But I expect that those researchers that work on quantum computers will always say that a breakthrough is around the corner, as in nuclear fusion. But that is just my gut feeling, reading about the progress being made with both technologies.
24. ## Guided evolution (split from Evolution not limited to life on earth?)

Strawman alert! If you are arguing against evolution, then argue against what evolution theory really says, not your uninformed interpretation of it.
25. ## What are the benefits of understanding our free will?

Nope. I tried to bend the discussion in that direction, finding the most useful definition, but it seems everyone wants to stick to their definition. I think this is the main problem when discussing free will: people first decide if we have free will or not, and then rationalise their viewpoint. I gave it a try in the other free will thread: But it did not help. I have the impression, that nobody ever gave a good argument against the concept of compatibilist free will. All arguments given are against libertarian free will, which for me is like arguing that circles have no angles. The concept of libertarian free will is just as incoherent as a circle with angles.
