Can physicists use tachyons and wormholes to build time machines?
What are some of the challenges of building a time machine using tachyons or wormholes?
There are many challenges that would need to be overcome in order to build a time machine using these concepts. For example, we would need to find a way to stabilize wormholes, which are thought to be inherently unstable. In addition, we would need to figure out how to control and manipulate tachyons, which are currently purely theoretical particles.
