Not only is the earth never in the same spot, the solar system it's never in the same spot either. Even our galaxy is moving.
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

The first book takes its time revealing the 'time travel', but the second book dives head first into using the technology proficiently.
Same spot relative to what? What object do time machines use as a reference for their coordinates? It would make sense to be Earth, so it would be in the same spot all the time.
Earth is a good one if you're only interested in time traveling on your home planet that happens to be Earth. But for a more universal perspective, I suppose the CMBR is the least arbitrary frame among all arbitrary frames
I thought about something like this when I was a little kid watching Back To The Future 2: "what if the ground had sunken somewhat since that mall was put there and the DeLorean emerged underground?"
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?🤔
I always assumed that teleportation would need to also be present for time travel. Clearly, just an assumption.
At least this way you get to see space as you die, my worst-case scenario would be time travelling and arriving inside a concrete dam
If they were orbiting a star for long enough, maybe. (Long enough = thousand or millions of years) Maybe a skeleton in a small cloud ?
If I ever find myself in this situation I'll spend my last minute poking holes in one side of my body so that every time I get closer to the sun and start to off gas I spin just a little bit faster.
That sounds about right. No decay in the traditional sense, hard vacuum in unfiltered sunlight is going to be a pretty great sterilization method. You'll offgas almost all of your water over time, so you'll be a spooky mummy at least.
Over time the raw power of the sun and random cosmic ray will "decay" you via splitting apart your component molecules, but i dont know if thats enough to truely poof you away or just make you a very bleached mummy.
Not decay as they would be frozen, obviously.
Sublimation. As long as it gets energy from radiation some atoms or molecules would randomy get enough to f off into space. In my theory, at least. And bones would stay last as they are the hardest.
Sublimation happens all the time. I got that from AlphaPhoenix on youtube https://www.youtube.com/watch?v=bnqQyeqGIBE Really cool science channel
I think radiation would riddle the body, taking small chunks out all the time so it would look like a swiss cheese skeleton.
Semi-relevant Tom Scott (actually about teleportation, but covers many of the same problems)
Wouldn't gravity keep you on earth as you are traveling through time?
