I was just watching Ian Morison on Fora.tv about Time, in chapter 14 he talks about wormholes and time travel. You can see the time travel part here: http://fora.tv/2009/03/19/Ian_Morison_Its_About_Time#Journeying_Through_Space_and_Time_in_a_Wormhole Anyhow, in short he mentions opening a...

Trying to reach the speed of light is like trying to reach an infinite speed. Which directly points out why that's so hard to do, no matter how long you accelerate at whatever acceleration you can never reach an infinite speed. You can't even approach it, no matter how long you accelerated...

Think I'm missing something here, would that not still be only possible if the 2d space was "bend" in the 3rd dimension. Otherwise, how can the space "know" it's curved/distorted?

According to this part in the same post it actually is, unless I misinterpret it.

Actually you're way off ;) Light traveling through a medium is slowed down, the amount it slows down depends on the density of the medium. The reason for this is that a photon just like anything else can't move through matter. What happen is the photon keeps hitting particles and the particles...

I'd have to guess no, not sure if gravity has any effect on sound, but if it does it's probably a very small effect. If it would then there should be a difference in sound inside a space shuttle or free falling aircraft. However if you'd put Earth's atmosphere on Jupiter the air pressure...

Density of the medium light is traveling through, every change in density will cause light to refract. The bigger the change, the larger the refraction. Since sound is a pressure wave there's also a difference in density (higher pressure = higher density)

Since there's a density difference in both cases it should refract the light. You can even see it with the naked eye on big explosions (the shock wave), temperature differences are easier to see like the apparent water on hot roads (mirage).

I was wondering, when we look at galaxies head on through a telescope, do we get a distorted view? What I mean is for example if the core is aimed directly at us so we see the galaxy from the top then the light of all stars is pretty much the same age. But in the galaxy itself there's a...

You could pull one out of any of these toys http://gyroscope.com/, but I think pretty much any (heavy) disc would do. But I don't know any of the math involved ;) Upside of those is also they come with starter wires ;)

It's basically just a rotating mass (see http://en.wikipedia.org/wiki/Flywheel), there are also some toy cars that use them (like http://www.madcattoys.com/cu1027kk.html ). The toy starts driving right away after charging it (by moving the toy) but you could make an alternative way to charge...

Maybe use a flywheel?

And recently read that the estimate mass for even the milky way was off by 50%, makes me wonder about the same thing.

Even though my geometry is kinda rusty, I don't think parallel paths can cross.

The static keywords turns the field into a singleton, this also makes it possible to access it without creating the containing class by using Classname.messageBuffer.
