if time doesnt progress at light speed then, if we could travel light speed we wouldnt age correct?
Correct, but we are made of matter, and the energy needed to accelerate matter to the speed of light exceeds the amount of energy in the universe. And if we did have that much energy, we would destroy the universe if we ever collided with even a single atom floating in space.
So we can go almost as fast as the speed of light and slow down our aging. But then, we are still limited to just the few nearest starts because at 10 light years away, a round trip would take 20+ years on earth. But if we went to more distant stars, time on Earth would have travel very far and family and friends would be gone upon our return. It's a common thought that a distant trip would be one way.
