We could benefit today from the knowledge of tomorrow!
If everyone from the future and past were to change our present at any time, would there even be a stable now?
I could give myself the Playstation for my birthday, which unfortunately my parents couldn't afford for my 16th birthday.
We would not only have to deal with the madmen from the present, but also with those from the future!
we could do accurate research in the past to better understand our history
I am afraid that I will meet myself in the past because I am exhausting
You could say goodbye again to deceased family members
Is just cool
Maybe you never come back...
You can also prevent corona or not let it spread so blatantly
Time travel cannot influence the passage of time or you can change history otherwise space-time would collapse at a singularity
There would be no more wars
Implication in paradoxes
You can warn about HIV
When you time travel and you come back from the past to the present, everything could be completely different because you accidentally changed something important.
Would be cool and you can maybe improve the mistakes you made before.
You could write exams in the future again travel back and then do them with a 1+.
Beginning and end no longer clear
Michael J. Fox
You know things that you may not want to know at all
I would be afraid to get in trouble again for things I have already done before.
