Question: One day do you think that there will one day be time travel so people can visit other planets and the galaxy's without it taking days or months?

Current travel is limited to be at speeds less than the speed of light, but certain physics does allow for the existence of wormholes which are theoretically a link between two points in space – but these are only theoretical. If they were real a problem may arise through being able to ravel through them. So, current understanding makes any other form of travel unlikely – but that is not to say some new physics may not be discovered one day!
