Hello.

I have read a little about time machines and going back in time, and whether that is considered possible according to modern physics.

Thanks. That's what I thought.

Can I ask which particular law of Physics prohibits it?

Basically, it just causality. There are MANY threads on this forum about "time machines" so a forum search would likely give you some good discussion. A good place to start is the set of links at the bottom of this thread.
