Ok, I really want to become a physicist that specializes in time travel. Like trying to make it real and things like that. What branch of physics would that come under? Thanks for answering!

TheJoninator said:Thanks, so what would 'time travel' come under?

TheJoninator said:Ok, it's just I've been reading this book about time travel by Michio Kaku and it seemed really interesting. By the way, what is Astrophysics about?
Dynamos said:What did Michio Kaku say about it? Was it just a thought experiment based on time slowing down as you approach the speed of light (i.e. like the one about a twin who travels off somewhere at the speed of light, returns to find that his sibling and the world has aged 10 years, but he himself hasn't), or was he serious about it? I know Stephen Hawking mused about it in a documentary. Basically he said that it would be theoretically feasible to go forward in time (for you) if you had the technology to travel at the speed of light. You could not travel backward, however (maybe b/c of entropy/unidirectionality of time?).
Anyway, by reading the links given by others, you will probably find something more feasible that also interests you.
Good luck.
Delong said:oh I'm sorry I just thought your post was really funny. I'm sorry if that made you upset. I don't have a good answer to your question since I don't know a lot about physics myself. I know time travel falls under relativistic physics and general relativity. I think physical cosmology would be the one that deals most with time travel (at least the theory behind it). Right now that is super science fiction if not science fantasy. I personally think time travel is almost logically impossible. But if you're really interested in it don't let me stop you. Physical cosmology and theoretical physics seems to be the way to go.
TheJoninator said:Michio was actually being serious about it, he was taking about quantum mechanics and things like that. Thanks for the information though.
Pengwuino said:None. It's not a serious academic subject, just science fiction.
f95toli said:I have to disagree here. It is true that no one is seriously trying to build a "time machine" or anything like that; but there are certainly theoretical physicists out there who work on the "nature of time" etc. Moreover, people do publish papers in serious journals about what is in effect time travel, but they tend to call it something else (e.g. "closed timelike loops"). Whether or not one could in principle build a time-machine (that can travel back in time) is certainly an interesting question which has wider implications for cosmology and fundamental physics.

The main types of physicists include theoretical physicists, experimental physicists, astrophysicists, medical physicists, and engineering physicists.
Theoretical physics involves developing and testing theories and models to explain how the universe works, while experimental physics involves conducting experiments to test these theories and gather data.
Astrophysicists focus specifically on studying the physical properties and processes of objects and phenomena in space, such as stars, galaxies, and black holes.
Medical physicists apply principles of physics to healthcare, working with medical equipment and technology to ensure accurate diagnosis and treatment of diseases.
Engineering physicists use their knowledge of physics to design and develop new technologies and products, such as computer hardware and renewable energy systems.
