Uhhhh... just take my word for it.
Actually as scientific theories go - this is not especially new. Over 25 years ago I switched to computer science from a double major in Physics/Astrophysics when I figured this out and that there was no way none of the fun stuff (time travel, faster than light travel) had even a remote possibility of happening in my lifetime.
I wanted to be able to do these things - it seemed nobody knew how - so I figured it all out and then lost interest as soon as it became clear we weren’t even remotely close.
I could tell you more, but I am not here on this planet to answer questions - I’m here to judge you!
I need to work more on saying things like that with a straight face.
