If the earth were to spin opposite of its orbit.. will time travel be possible

i know this is a really stupid question but

can't a dude be curious?

Time travel is already possible ... so long as it's into the future. It's happens all the time. You are traveling into to the future right now. So long as you are moving at some speed relative to something else, you will be moving into the future faster than the thing which is moving at slower speed. This is a fact.

Two cesium clocks synchronized on Earth. One is put on a jet plane which flies around the world (at about 600 mph). After the trip, one clock will have ticked faster than the other, proving travel into the future is possible. Astronauts, who travel millions of miles at 17,500 mph for an extended period of time age a tiny bit slower than everyone else not traveling at that speed.

Time into the past is not possible literally so far as we know as it creates rather odd paradoxes which make it difficult to sort out; like you going back in time, and killing your grandfather which would prevent you from being born so that you could not go back in time to begin with.

No; chances are it isn't possible at all, but if it is, the earth spinning in the other direction will not make time travel possible. It would however result in complete tragedy. Even if it happened slowly(obviously if it was immediate all life would be smashed into the thing next to it at about 1000 miles an hour) the weather effects from the wind patterns being reversed, would result in huge atmospheric changes, not to mention the environmental effects that would result from the altered weather. But to answer your question, no time travel.

No, because time only goes in one direction, as far as we know. Time is an intrinsic component of the universe. The laws of physics break down if time is not included in mathematical. How time is MEASURED is determined by mankind. Just because Earth gets flipped like Venus and Uranus were flipped by one or more collisions with massive bodies doesn't mean that time goes flows backward on Venus, Uranus (possible pun NOT intentional) or Pluto. (Pluto is also flipped, just not as much
