I don’t remember the name of the novel, so somebody help me with this. The concept is basically that scientists invent time travel, but use it as a teleportation device instead. Set the machine by a few seconds, you teleport the distance covered by the Earth during that time. They even use the technique to plan for an assasination of Kim Jong Un. Loved that one. Some innovative sequences using the ‘time machine’.
Edit: Found it. It’s actually two books (original and sequel).

and
Time Frame - https://www.goodreads.com/book/show/37946554-time-frame
The first book takes its time revealing the ‘time travel’, but the second book dives head first into using the technology proficiently.
Well, I’m glad we got to the bottom of what’s unrealistic about traveling back in time…
Time and space are pretty much linked so if you travel in time you can travel in spacetime :)
Yeah, but to my knowledge, you can only go forwards in time.
What you can do, is go forwards at a slower speed. So, if you sat yourself in a spaceship and accelerated to e.g. 10% of the speed of light, you might get out after what you perceive as a few years and find yourself in the year 2200 (I did not do the math), but you cannot go back from there.
Causal chains always have to follow causality. They can just do so less quickly, because, as far as my current understanding goes, the speed of light is actually the speed of causality.
(Sorry to bonk you with so much physics. I know that initial statement could have also come from someone who’s never heard of the theory of relativity…)
