Is time travel possible?

Are there any ideas what they could be? I thought that antimatter was the best there was?

Unless you can go and "mine" antimatter (e.g. positrons from a radioactive decay), it's not an energy source. It's more like a battery — energy storage. You have to put energy in to create it, and the ways we do that are really inefficient.

interesting you say that, but why antimatter?

I thought that was the most potent thing we could use for propulsion, but thinking about it maybe a blackhole type engine, but is that even possible outside of Star Trek?

maybe something more exotic would be needed. Dark energy maybe.

Question is, how much energy exactly is needed to time travel? What speed is necessary to reach a useful time dilation? Such as, if I wanted to travel 100 Earth years within 1 hour how fast would I need to go and how much space would I travel in that hour?
