Re: escaping a black hole?

And on an unrelated note, why would a black hole be really black? I would imagine that there are a lot of interactions going on outside the event horizon that would produce a photon. I would also imagine that a lot of atoms would be orbiting the hole in their death spiral that would interact. Photon...

Question about charge of electron and proton

if the proton has an atomic mass of 1 and a charge of +1, why does the electron with a significantly smaller fractional mass have a value of -1? Is the electron that much more powerful?

Re: The "How Have I Never Noticed That Before?" thread

A lot of children's cereals have the cartoon characters looking downwards.

Why? Because children sitting in the shopping cart will be looking upwards and will make eye contact.

This establishes an emotional connection to the character and helps reenforce brand loyalty.

So if I'm understanding this right, The speed of light is c, while many other things are also set to c as well. The SoL does not define C, C defines what the SoL is, as well as the speed of gravity and any other massless particle. We just call it the speed of light due to historical nomenclature. Th...
