People say this but the reality is that you are already traveling through time and you aren't teleporting into the space where the Earth used to be. Just as traveling backward would essentially just reverse that process. i.e unless you specifically design a time travel device to kill you that way, thats not how time travel works.

I think a time travel device would, itself, need to be a spaceship anyway. And since it would have to travel FTL to achieve time travel in the first place, getting back to where Earth is at that point in time shouldn't be difficult.

If your time machine works this way, if you're not isolated from reality while you travel, you'll have to do everything at crazy speeds and potentially backwards and you'll be limited by the age at which you're reasonable enough to be able to travel back. You won't be able to travel to times when you don't exist as a person.
