Any object possessing mass would require an infinite amount of energy to reach this speed, which is impossible. This is derived from Einstein's famous E=mc^2 equation. As an object is accelerated, it becomes correspondingly more massive. The concept of a light year is also strange to one travelling at a very significant portion of light speed, as time *slows down* for that person relative to those left behind.

If you believe in God and you're right you go to heaven. If you believe and you're wrong, you most likely lived well and people will remember you well. But if you don't believe and you're wrong, well.......oops!!! And what a price to pay!!! God or No God? If you believe in God and you’re right you go to heaven.

It makes me wonder if 1 light year is so far, what is the furtherest distance we can travel with our current capabilities and whether the experiments they are conducting with the hyron collider will lead to some technology that will enable us to travel at speed near the the speed of light? It certainy is.

And there were discussing stars that we millions of light years away. It really does put into some form of perspective the vast area that we call space.
