Oh wow, that is really cool. Thank you very much, that clarifies a lot. Thanks for all of you guys' help!

Yes, I looked them up before I posted that. I'm sorry, I was just stating that I am confused about something else now: it looks like the masses of the nucleons don't add linearly. I understand if my new question is a bit off topic. Should I start a new thread?

But... Doesn't Boron have 6 neutrons and 5 protons, where Carbon has 5 neutrons and 6 protons? What am I missing here? Apologies, but my knowledge of nuclear physics is elementary, at best.

I've been wondering about positron emission. If a neutron has more mass than a proton, how can a proton turn into a neutron by releasing a particle with mass? [PLAIN]http://img37.imageshack.us/img37/654/positronemission.gif (source:http://en.wikipedia.org/wiki/Positron_emission) Doesn't this...

Say you build a stable wormhole from Earth to Alpha Centauri. You've got two portals, one on Earth, and one in Alpha Centauri. Now, say you drive your craft (that can go .99% c) into the portal, and you end up in Alpha Centauri. You drive back to Earth without the wormhole, and it takes 4.4...

By conventional means, the faster a massive body moves through space, the faster it will move through time. So, when that body approaches the speed of light, time around it begins to stop. Then, if you found some way to move faster than the speed of light (by use of pushing off of something...

This isn't really an answer, but it's something to think about for your question #2 Here, say that you travel instantaneously to Alpha Centauri. If you look at the earth, you'll see what it looks like 4.3 years in the past, because the photons are sill getting there. Now, if you were to wait...

Thanks for all of your help!

Does gravitational lensing cause blueshifts or redshifts?

http://en.wikipedia.org/wiki/Schwarzschild_radius What would these black holes be made of?

Could it be possible that there is enough black holes/star clusters/neutron stars/dark matter to create these curves, and thus these redshifts, that would fool us into thinking that the universe is expanding (while not really expanding), because of all the redshifts we perceive? The universe...

Sorry, I recently realized that light doesn't orbit at the event horizon, it orbits a bit away from the event horizon, actually. Also, if black holes colliding creates a gamma ray burst, wouldn't that mean that the light is blueshifting?

Curved from the Earth's frame of reference, right? So it looks like it's curved to us, because of the light's apparent change in direction? (From Earth's frame of reference, of course.) So say that a photon were orbiting a black hole on it's event horizon, would the light continuously redshift...

If light is moving on a curve, for instance, if light were bent around a massive body thus curving due to gravity, does it undergo any redshift of blueshift? I ask this because the universe may not be expanding (what we see as redshift), but may just be affected by gravity, and curving, thus...
