relativity

I am writing about relativity both special and general relativity. I am curious about time travel idea. Do you have any idea to share about all facts and cons of time travel.

I'm not sure why you included the commercial link, but your question about time travel can be discussed without it.

Forward time travel is indeed a possibility and within the laws of physics. In fact at very small scales it is occurring every time one of us takes a plane trip somewhere or other. Basically it goes like this...the faster one travels through space, the slower one travels through time.

Time travel into the past is another kettle of fish and probably not viable, as one would need to go faster then light.

Kip explains it far better then I.....https://plus.maths.org/content/time-travel-allowed

What about CTC (closed time like curve)?

A mathematical solution/idea that is allowed for in GR but like a wormhole, still at this time speculative.
