Starship Asterisk*

I've noticed that many people believe that the universe is expanding. Actually it is difficult to find an astronomy professor or a "gravity physicist" who wouldn't. Despite such popularity of expanding uiverse model I didn't find any evedence that Einstein or Richard P. Feynman believed in...

ari, I see that makc answered your question several minutes before I managed to post mine, so now you have two answers.

... is an active field of theoretical investigation but has yet to be observed." :roll: Why the rolling of the eyes? Read the last sentence of wikipedia's article and let me try to explain makc (who probably is going to correct me if I'm wrong): Things that are not observed don't belong to phy...

Einstein solved the Newton's dilema by assuming that instead of "attractive gravitational force" acting at a distance the time runs at different rate in different places and the space is curved. This assumption turned out to be enough to change Newtons law of inertia in such way that when...

With, however, non-locality proven and saying Relativity is wrong. http://en.wikipedia.org/wiki/Non_Locality Sorry ari but I don't see why this article tells you eiter that non locality is proven or that relativity is wrong. You should explain why you have such an impression with your own words so ...

If I carefully place a pebble in the air, why does it fall to the floor? Jim tells me it feels no gravity, so the law of inertia tells me it should remain where I placed it. But every time, it falls to the floor. What's going on? That's a question that Einstein had to answer too. It turned out that...

Jim you know it very well, or at least you should, that Einstein's "blunder" was referring to his quest for static universe, for which he made a hack to original GR by adding cosmologic constant; but when observations were first interpreted as if the universe was expanding, he said that, ...

And who might have done that? A quote please ...

Even if no one else, I still think it's very cool, one of best scenes in a movie.

I share the above opinion and I'm glad that you have sense of humor (see my post above).

Einstein's Biggest Blunder? Dark Energy May Be Consistent With Cosmological Constant Mark, so called "Einstein's Biggest Blunder" might had been (my wild guess) a joke by Einstein who didn't expect that cosmologists didn't have any sense of humor and they might take it seriously. How come...

A smart thing to do. It prevents you from beliving in the BB.

I just wanted to point out that Feynman didn't actually say you can't prove anything with math. He did in a sense that one can't prove any theory. Once you can prove a theory, it isn't a theory any more but a fact. One can only prove that a theory is wrong. It is a known episteomological principle ...

what can be easier than "it moves because a force makes it to"? a = f / m? This is easy, but the tough part is "where is this force coming from?" It took a lot of time to find out. In the meantime it was even thought that angels (invisible of course) are pushing the planets arou...

yeah.

Which part is too complicated?

Please be aware that I don't mean that your explanation is wrong in any cosmic sense, only that it does not actually explain anything. To take a different example: if you and I were moving away from each other without any visible reference frame, we could express in words our opinion that one of us...

So is gravity a finger print from each layer from What came before? which can not be removed from each kind of matter? 1 A Gold particle is its gravitational mass because of where it was created deep inside a star? and that force takes a long time to leave it? 2 A helium particle was created in a d...

Hello JimJast, Can the idea be carried to something like a permanent magnet even though free falling bodies and magnetism are not the same thing? It can be carried as fas as "magnetic energy" is concerned since any energy included into E=mc^2 counts, but you might mean something else, and...

This "6th sense" is called "quantum mechanics".

1. I think you have simply redefined pull as push. That is, you've said that there is not something pulling us down by acting at a distance, but there is something pushing us down by acting at a distance. It isn't just redefining pull acting at a distance as push acting at a distance since the push...

Scientists from the Evangelical Center For Faith-Based Reasoning are now asserting that the long-held "theory of gravity" is flawed

... Nature does not see any forces acting in the univese causing those movements. It sees only forces like those that press us against the Earth, but not any moving the Earth around or a stone thrown into the air. ... Huh?! You think there is a force pressing "us" to the earth, but that t...

Gravitational Radiation http://math.ucr.edu/home/baez/physics/R ... ation.html Unfortunately prof. Baez might be wrong about gravitational radiation being of spin 2. The reasons are too compex to be suitable for this forum so let's consider it just a controversial issue. The same as non conservatio...

Do you undertand now what is the problem with your (simple) explanaton which pretends that it is explanation of physics while it's only explanation of (simple, Nawtonian) math? I understand that there was no problem at all with my explanation. It is intrinsically simple (as opposed to simplified) b...

We experience some gravitational force from every massive object in the observable Universe, not the Universe in its entirety. Small or distant masses produce smaller forces than large or near masses. All the force vectors get summed to come up with the final, experienced force. What problem do you...

Jim, this is bullshіt tactics, like a page ago when you asserted that my quote was directed at BB theorists, when it was crystal clear that in fact it was addressed to you. makc, be serious, how Feynman could address me if I was not at this conference. He clearly meant only "126 dopes" wh...
