Comment on space

So to travel into the future and be in the “same place” relative to your planet you’d need to solve the n-body problem for at least your local system to a suitable length of time. A slight error might mean you appear inside the planet or in outer space.

Or maybe I don’t understand this stuff. :-)

Mass bends spacetime so one could assert that a time machine could anchor itself to a sufficiently large mass, just like how things in orbit are still bound to the earth’s mass.

You'd also need to solve time travel.

You’d just send a drone back to say 100 years for instance and have it send you exact coordinates into the future.

Time paradox aside you’d probably have this data already, with all alternatives and can correctly time jump right away.

  But by the time you have collected and evaluated all the drone data you and all the masses around you would already be in a totally different configuration, making the data useless.
  
  But maybe a little jump to the time when you sent the drone out would be easier and then you could use the drone’s data.
