    Nah we probably don’t know how old the universe really is since we don’t know what is beyond the EH and information may be lost. We don’t know where the center of the universe is.

    Still with all of the energy combined in this known Universe would not be a fraction of the energy required to recreate the Big Bang. So what does this tell people?

    00:05 Time travel possibilities explored through a paradoxical narrative 02:27 Time travel concepts and paradoxes 07:23 Time is like a river from the Big Bang to the universe's demise. 09:52 Space and time are interconnected in the fabric of space-time. 14:56 Our universe operates like a book with pre-written events 17:30 Cosmic rays creating muons open possibility of time travel 21:51 Faster travel makes you heavier and affects time. 24:01 Time dilation can be used for time travel into the future. 28:12 Speed of light is the ultimate speed limit in our universe 30:19 Time travel to the past is restricted by the speed of light. 34:23 Wormholes can enable time travel without breaking the speed of light barrier. 36:16 Various theoretical methods for time travel 40:35 According to the many worlds interpretation, the universe constantly branches into separate streams of reality. 42:41 Backwards time travel is impossible due to universe safeguarding cause and effect. 46:48 Every Quantum transition splits our world into myriad copies

    Is the universe perhaps.... repetitive? Like everything is a reflection of its lower magnitude so of we find a wad to see through the repetitiveness then we can map out anything?

    Thanks for this, I admit being confused at times, but I intend to rewatch until I can follow along, the end was very depressing, I know that is hundreds of thousands of years away, but still super depressing, I hope we discover how to avoid the absolute end of everything!!!!

    All these "Fine Tuning" turns out to be a hoax, a result of the nonsense called Standard Model. It is the by necessity the result of the dozens of arbitrary constants that needs to be filled through experimentation, and cannot be derived through first principles. When we finally discard this clunky Standard Model, then all the fine tuning will also be discarded.

    I like to say that time travel to the past is probably impossible, but time travel to the far future is a fuel problem. The world's biggest fuel problem, to be sure, but just a fuel problem nonetheless.

    Wait… what if the reason our universe, or at least what we can see is expanding so fast because on the other side of the universe everything is contracting? As in on the other side of the universe the tug of war is in favor of gravity and everything goes to one point and explodes and expand making our side of the universe shrink again and explore repeating the process?

    What humans do to prove they have free will, everything could be the awnser, but humans try everything to make up something where it proves free will. I don’t believe we do. We are set in our path, destined to die a life already lived by someone else
