, 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.
Could the endless loop be what people are seeing but THINK they are seeing ghosts on an endless loop?!!! 😮
If time travel is possible than it has already happened...and not happened🤯
Who's watching in 3077?
I love time travels.
I would love to watch more history channel videos but the commercials are EXCESSIVE!! 🙄
I take a stand to say YouTube premium to expensive about 19 bucks a month
the worm hole concept is pretty cool, this is the first time I've learned a lot from history channels views, god bless yall
Love that this episode keeps using a specific cut scene from Buck Rogers In the 25th Century movie and TV show.
I time travel all the time
Great video...thanks for posting!!!
The earth spins and rotates around the sun, which spins around in our galaxy which spins around the universe. We're never ever where we were a second ago. So even if you figured out how to travel in time, you'd probably just leap yourself into a void.
Wormholes are scaaaary, because if you try to go through a wormhole you have to avoid all of the giant worms that want to eat you.
You can travel to the past or the future since the Universe is running time in different dimensions and there are so many. Anyone ever have the feeling like they have already done something whether it’s months or years later….thats you in the future. I think the different layers in the Universe are different time zones basically n just a matter of which part you want to visit
I'm kinda amazed they just talk about movement to be able to trsvel through time! I would have been interresting to hear their views on static time travel like in Jake Gyllenhaal's movie "Source Code" which btw is a great movie!
I would like to go back to November 19, 2021, I have to tell my mom that I love her. Too late now.
At the point of alteration it changes course and you begin a new parallel universe off of the original.
T.I.T.O.R. Travelers In Time Over Relativity
ancient astronaut theorists say yes .
Ticking away the moments that make up a dull day. You fritter and waste the hours in a offhand way
