Sigh-Fi

Yes! Thank you. Lots of time travellers lost in the void or buried in solid objects.

Some possible ways of dealing with this:

• The time travel device does the complicated math to get the time and position correct, assuming the SF writer only wants to deal with 4 dimensions.

• Tunneling effect so that it's a straight point to point between the two timelines.

• Get Weird. Invoke quantum entanglement to rearrange the exact same atoms that make up the time travellers' bodies in the destination timeline, because mass/energy can never be created, only borrowed, and perhaps the universe has a conservation of mass/energy rules and can't add more mass/energy from a foreign timeline without tipping the balance from a "Big Rip" end of the universe event to a "Big Crunch" event.
