There ’s a possibility that fan of time travel story wish to toss around : sentence travel not only has n’t been cook up yet , it wo n’t be in the hereafter either . Otherwise , we ’d see sentence - travelers popping up in chronicle . Here ’s an alternating — and pretty unsettling — possibility .
After read about the likelihood that any travelers who go too far back in the past would find themselvesin dire need of an atmosphere suit , commenterCool_Breezeshared this nervous theory about where we should look for clock time - traveler :

Not only does a time machine have to travel backwards in meter , but also in space . globe is constantly moving , and pinning down it ’s exact locating x years ago can get tricksy . mean about it :
1 . Earth ’s rotation on an axis that shifts approximately 20 degrees every couple of million years . The Earth ’s wobble must be taken into report ;
2 . Earth ’s stance proportional to the Sun ;
3 . The Solar System ’s emplacement comparative to the center of the Milky Way Galaxy . Our system revolve once every ~250 million years ;
4 . The position of the Milky Way Galaxy in relation to other beetleweed , and their gravitational force outcome on the Milky Way ;
5 . The attitude of the local galactic cluster in sexual intercourse to other clusters , and its position comparative to the gravitative effects of the big bang ; and
6 . Any number of random gravitational encounter that may regard any of the above , including but not limited to rouge stars disrupting our Sun ’s electron orbit around the galaxy , rouge planets ’ and stars ’ gravitational effects on Earth ’s rotation around the Sun , retiring and next astronomic collision ( Milky Way v. Andromeda , etc . ) , crustal plate tectonics and climate changes on Earth that affect the emplacement , ALT , and existence of various places ON Earth .
Get one of those wrong , and the want of O in Earth ’s atmosphere will become a very narrow problem .
My hypothesis is that the reason we do n’t see any time traveler now is not because they do n’t exist – but rather because they calculated wrong and are float in distance somewhere , never to be seen again .
