I have recently heard of a theory that states that faster than light time travel is possible by disrupting the fabric of space-time using tachyons, to create a makeshift wave behind a future spacecraft of some sort. It states that by doing this, one creates a bubble around the spacecraft. And inside that bubble, speeds are way below 180,000 Mp/s., but outside the bubble, speeds are much higher than 180,000Mp/s. It's kind of a loophole in Einstein's theory about light speed travel. Thoughts on this idea? I personally don't think it's possible. One reason is that, if tachyons are real, I don't think there's any way for us (Made of Normal Matter) to interact with Faster than Light particals. Oh, btw, I'm new here. Hi everyone.
