So there were smart phones in the mid 90s? Future Time Traveler caught on tape at Tyson fight

[TheAlbionist]

Science could have found out how to travel back in time this decade . They just keep it covered up

Time travel doesn't get discovered at one specific time unless it's only travelling forwards.

If time travel backwards was going to be discovered, it would have been discovered for all times instantly and we'd already know about it because there'd be people from the future everywhere. The entirety of the human race is going to keep it a secret for the rest of eternity? No way... only takes one person to let the secret slip in 99999999999999999 years and everyone instantly knows throughout the entirety of time.

Time travel ain't happening.
