I was thinking to myself that the only way we are ever going to be able to explore space properly is through the mastering of wormholes... then I thought about how time doesnt pass for something moving at the speed of light. so I was wondering what you guys thought about the relation between speed and time and exactly how fast we need to go to make deep space exploration plausible, and what is going to be more likely us reaching near speed of light or us mastering wormholes...

Will we ever be able to go through time?
It would be indeed impossible to go back to the past.. but the future is another thing.

What can we want from time travel to do for us, if not only go to the future?
Well, in a way, we could. even now.
However, it does cost us our lifespan to do it.

Such as taking a sleeping pill and set an alaram for 4 hours later. You are in a way, going to the future of 4 hours from now, since you are uncouncience during that time.

With technology progressing, it wont be difficult to imaging a device to do it in a more practical way.

More thoughts?

Time is the change of what?
