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).
Split Second - https://www.goodreads.com/book/show/26216031-split-second
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…)
You just need to reverse entropy haha
Suppose you get the location right too, I assume the difference in momentum will… not be forgiving.
It’s amazing how plausible this is
Well, I am traveling forward in time in home made Time Machine with the speed of one second per second. I do not see any problem you are describing. Now I just need to add the reverse, but I do not expect any issues of this kind either.
In this case, it makes sense to time travel from space and land on a planet upon arrival. Maybe all UFOs are just time travellers after all?🤔
Relative to the position of the Earth, the Earth doesn’t move
Weak premise considering the principles of relativity, and how our current understanding of time travel is basically rooted in SPACE-time.

I read that ages ago. Back in high school, in fact (I’m 46). I don’t remember it except the chapter where time is a flock of birds that you have to try to catch to stay youthful. The children can catch them but always let them go and the adults can never catch them.

I remember it was in the new books section of the school library and I was attracted to it immediately and spent the day reading it instead of paying attention in my classes. I need to read it again. Thanks for bringing it up!

I always assumed that teleportation would need to also be present for time travel. Clearly, just an assumption.
