why does it have to be light? can it be something else? just as fast?

A recommendation.
If you are interested in this topic, please consider viewing the PBS documentary "The Elegant Universe".
Even if you don't subscribe to a particular view, scientific or fantastical, it's an entertaining series.
Even if you don't believe in conventional scientific view, it's helpful to know what that view is. Rather than just saying 'oh, I think Einstein was fake', you should then be able to more elegantly clarify your assertions in such things.
It's available free, online and on youtube, usually in 8-9 minute segments, and is a total of three hours.
Here's a link:

Without some background, I fear posters are wasting their time, not to mention wasting others' time with unresponsive commentary.

I’m going to go out on a limb here and agree with you. What Einstein said was a theory. It has not been proven right or wrong (if I understand my science correct).
In my mind, I don’t see why we couldn’t, besides the fact that we would need massive amounts of energy (once again, if I got science down) to do this.

Just wondering? Why can't we travel faster than the speed of light? I have read that most scientists agree with Einstein when he stated that we will never travel faster than the speed of light because as a object nears plank speed (Close to the speed of light if I understand correctly) it's mass becomes infinately larger, so there is not enough power in the universe to push it past the light barrier. But why not? do they have proof of this or is this still a theory. Haven't scientists pushed particles to the speed of light in accelerators (SP)? or are they stuck at a percentage of the speed of light? I am just currious. if it is a power problem then why couldn't you use the energy released by the anialation (sp) of matter/dark (anti) matter? if there is as much dark matter in the cosmos as I have read then there should be an abundance of "fuel" available for the "engine". Just a thought.
Could some of you help me fight ignorance? Thanks
