The news always depicts them as real http://www.bbc.co.uk/news/science-environment-13964767 But as far as I gather from reading this forum and wikipedia, black holes are always said to be "candidates" Has it been proven "beyond a reasonable doubt" that they exist?

Is the answer to WHY not simply because if you agree that c is constant, which is distance/time, then the only other two factors that could have changed were distance and/or time? If you can take on board that that is the case, then you are really asking why is c constant, to which I don't...

http://en.wikipedia.org/wiki/Time_dilation That answers your questions?

Great answers as usual!

I was watching a lecture by Prof Wolfson, and he said there was an experiment where a particle was split, I can't remember which, and so either charge was positive in one direction and then negative the other, or spin up and spin down, but in any event the two new particles were sent to two...

Thanks, I'm glad that is the case, it makes logical sense to me that way that if c is measured the same for both observers that from A time and distance would need to be measured differently in order for c to remain the same

Thanks guys, a lot of good answers

For my own understanding, I understand why space and time differ if we assume c is constant, but when the "moving" clock is observed from the "stationary" point A, does that mean from point A, or from point A "if the information from the clock was given to point A instantaneously"? i.e. is it...

Whenever I read about or listen to things GR related, physicists always say "with incredible accuracy" or other words that imply GR isn't 100% accurate, i.e. they never use the words 100% accurate How innaccurate are they talking? A popular one always seems to be the planet Mercury's orbit

I say inflation, I might possibly not mean it. I've read that the expansion of the universe is accelerating, and it's a mystery why, but my question is why isn't it expected to appear that way? If the masses of galaxies are spiralling towards the center where gravity is highest, and as more...

Sort of off-topic but addresses your first wish If you search for TTC Quantum Mechanics, TTC Particle Physics and TTC Relativity you'll get some somewhat lengthy but very informative lectures from the teacher training company (I think that's what it stands for)

Neutrons are composed of quarks and do have a strong interaction

To demonstrate that C is a conversion factor

I am new to all this "stuff", so please forgive me If GR describes gravity as a straightline movement through a curved space-time, why does there need to be a "carrier" at the quantum level? What would it be carried between? When people say at the quantum level GR stops working, is there a...
