That is why a Time Machine will never be practical.
Everything in the Universe is in motion. Even us sitting here in front of our computer screens are moving at thousands of miles an hour.
The Earth, the Sun, the Galaxy are all moving.
If a Time Machine was actually a reality, the first time it was used you would probably die within the first few seconds, because you would wind up in intergalactic space and no way to get back.................
The past happened and the future hasn’t which is all based upon Earth time - in space, there is no time.
