@History , Please consider including the original airdate of the videos you post. I looked this episode up on Wikipedia and discovered it originally aired 8/19/2010. It would be extremely helpful to know this, especially for science topics, to keep in mind the theories presented may not be the current school of thought.
Rewind back to the 80's and leave me there.
I would love to watch more history channel videos but the commercials are EXCESSIVE!! 🙄
Who's watching in 3077?
ancient astronaut theorists say yes .
Dude said remember the future but never listened to vaporwave. 😂😂
That's not how time travel works.Changing the past doesn't change the future
Dragon Ball already explained this, when Trunks travelled into the past, he created a new timeline 👁👄👁
The ideas that "nature" or "the universe" will prevent you from changing the past assumes that "nature" or "the universe" is somehow conscious and able to "choose" to act on your choices, like creating an entirely new universe. Ridiculous. It doesn't, it's just nature. If you prevent your grandfather from meeting your grandmother, you simply won't be able to return to the future because the mechanism you used to time travel is no longer available to you because the future's been changed regarding you.
I don’t think we ever achieve time travel because if we did, we would see a bunch of people coming back now
