Curious layman Posted June 17, 2019 Share Posted June 17, 2019 Forward time travel definitely (time dialation), backwards I'd say impossible, but not 100% on that, I've heard arguments that say you can and you can't. in practice though I'd say both are impossible due to the amount of energy required.

zapatos Posted June 17, 2019 Share Posted June 17, 2019 What if we discover a new energy sources? For instance, how much energy is required to move in time 10 years? Link to comment Share on other sites More sharing options...

Just occurred to me.... the new energy source would also have antimatter! Duh. Link to comment Share on other sites More sharing options...

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. Link to comment Share on other sites More sharing options...

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. Link to comment Share on other sites More sharing options...
Art Man Posted August 26, 2019 Share Posted August 26, 2019 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? Link to comment Share on other sites More sharing options...
