Best Travel Infos

Joop asked:


My Optics lecturer said something about how since light travels in a vacuum, you could, potentially, have something travel faster in a different medium, one other than a vacuum.

True or false?

Apparently, we can travel faster than the speed of light they say. Its like the universe expanding faster than the speed of light. The analogy I heard is ants on the surface of a balloon, they don’t move but the baloon expands and they become farther apart (traveling at the balloon expansion speed which represents the universe expanding). I am not sure if I understand all this. Has someone got a scientific explanation in simple words for a non-scientist? Thanks.

If we could travel at the speed of light, it would be possible to escape time thereby negating the concepts of hours, minutes ~ years. Thus we could move from anywhere to anywhere in an quantified instant, making the most distant parts of this universe just a hop, skip and a jump away (minus the skip and the jump). Am I looking at all that correctly?

And how far are we from achieving that, short of a monumental breakthrough Quantum Physics?

aaron g asked:


I had just read that the closest galaxy to ours is 1.6 million light years away and that there are something like 200 billions galaxies. Is this correct information? Also, about how many stars are there in the universe? Given the age of the universe, how did matter reach such distances traveling slower than the speed of light? What’s the fastest speed the furthest galaxy had to travel to reach it’s current point in space?
I made a typo - How long would it take light to travel from the center of the universe to the furtherEST galaxy?

compared to the speed of light i would like to now how fast the current space shuttle travels, how fast the space craft winner of project X travels and how fast the successor to the space shuttle will travel.

I want to travel the Universe with my wife and leave Earth behind. Without spending billions of dollars like NASA does on a spaceship to leave Earth and not going very far, is there any way that I can build one and travel faster than the speed of light without damaging our bodies? I know this may be complex but how would I go about doing it? Only serious answers please if you honestly know.
