Pretty sure this was the plot of "Future Man" which is a really funny comedy series I recommend.
Eitherway, the guy was trying to save the world by time travel only to find out that every time he traveled he essentially traveled to a different reality/universe/world, so every time he fucked things up, he was just fucking up more and more distinct worlds -
@JS-Guy exactly. Not being able to change anything is the only way to solve all those causality breaking paradoxes.
According to General Relativity, time travel should be possible, but logically it shouldn‘t be possible. Unless you travel to different worlds (instances of the universe) and can‘t change anything that would affect your future you (the instance of yourself that is actually you). -
@Wisecrack I‘ve got a phd in youtube physics.

@Wisecrack Gedankenexperiments don‘t require knowledge in physics :)

@Lensflare let me know when you invent a time machine in your garage.
I want to join you to engage in time hi-jinx.
We'll go on wacky adventures together and discover the power of friendship or some shit like that.
Bonus points if its built into a telephone booth or a delorean. -
@Wisecrack I already invented a time machine based on the delayed-choice quantum eraser.
The problem is that it only can send information into the past, not macroscopic objects, let alone people.
But it could be used to send binary info and encode some lottery numbers.
The other problem is that it‘s practically impossible to build because you‘d need to trap multiple photons bouncing in a mirror for the amount of time that you want to send them back for each bit of info.
That‘s a practical issue though. In theory it totally works :) -
@Lensflare "delayed-choice quantum eraser"
Heard that phrase before, totally unfamiliar though.
Clue me in.
when your code is a mess but everything work out in the end
When you keep getting +1s on a rant you posted a month ago.
Go big or go home.
Let‘s talk about time travel and the bootstrap paradox (look it up if you don‘t know what it is)
I think that I have a solution for this paradox, but it requires the many worlds interpretation (quantum mechanics) to be true.
I‘m in the many worlds camp anyway.
So, how can an object exist in a time loop? The paradox is that it looks like it has no origin. It wasn‘t created. It just exists.
What if the act of time travel puts you into a different world, just like any decision puts you into a different world?
I‘d argue that the object has an origin and it was created. But it was created in a different world (different timeline, if you will). The person who observes the object in a loop is not in the same world as the person who observes the object being created.
After its creation, the object has entered the loop and by traveling in time it also traveled into a different world, where the creation event never happened.
This also solves the grandfather paradox in my opinion, because there is no contradiction when you go back in time and kill your grandfather. You are in a different world. You will never be born in that world, but so what, you are from a different world.
What do you think?
