Many worlds means they exist in parallel, this would be them existing in sequence with each one discarded and replaced with the next until one is stable.This seems to tie in to that in a way? I mean, for the Universe to "course correct" into innumerable different scenarios to get to the "same" outcome, wouldn't it have to have infinite different variations?
That's how I'm reading into it at least
Dude, they ran the numbers. They did science.The article contains precisely zero content explaining how or why the paper comes to this conclusion. That should be enough of a red flag.
A whole lotta fuckin'.This is what I'm getting too.
So, let's say hypothetically, a time traveler goes back some number of years and triggers a human extinction event. How and what will correct itself if the human race no longer exists?
WoahI still like the theory that the Titanic sunk because of overcrowding by Time Travelers.
Back to the Future 2 had it right, I think – except you probably would never be able to go back to your timeline the second you arrived in the past
I honestly don't think that time travel exists since time is always moving "forward"
You're assuming you can kill yourself. Under this scenario, you couldn't/wouldn't.

What if you go chop your own head off as a kid how's it fix that? Haha
So if future humans have the power to create a weapon that can instantly blow up the earth and a future dude takes it back in time and destroys the planet with it, the earth would find a way to reform and things would be hunky dory?
Killing Adolph Hitler means Randolph Hipster would take power in Germany and still cause WWII and the Holocaust??
Turns out he survived
The quote seems kinda... fantasy?
Like, time travel is magic that understands the importance of events and then changes how they happen.
And even if it did, changing patient zero from one person to another could have totally different effects that change the outcome completely.

I've seen this story getting picked up by several news outlets. I think a 6th grader or a sci-fi writer wrote this paper?
Not sure how someone could possibly come up with this who thought about this in any logical way.
nuh uh, my scientific paper says YOURE FANTASYThe quote seems kinda... fantasy?

It turns out you didn't actually kill him and hospital workers managed to save him while you were on your way back to the present
"Forces" would somehow stop the former from happening. The intent may be for future dude to do so, but he's already done it, so it didn't work for any number of reasons (he was killed before he could use it, the mechanisms in the weapon failed, the weapon had never been tested at scale and an interaction of it being used had an inverse effect, etc).
"Forces" would do something similar for the latter in their theory, too, if I'm understanding it correctly.
Essentially, if it happened, it happened, and any interference from the future was actually either part of ensuring it happened or failed to prevent it from happening. Which also postulates that the future already exists, I think...
Your birth is out there in space-time. Your death, too, is in space-time. Every moment of your life is out there, somewhere, in space-time.
So says the block universe model of our world.
According to the block universe theory, the universe is a giant block of all the things that ever happen at any time and at any place. On this view, the past, present and future all exist — and are equally real.
How can this be?
The block has four dimensions: three spatial dimensions — say length, height and width — plus a fourth temporal dimension, or time. Or let's make it easier, by visualising the block model of our world as a three-dimensional rectangle, or cuboid.
Two of that cuboid's dimensions (let's say height and width) represent two of the universe's three spatial dimensions.
The third spatial dimension in the above diagram is left out — the length of the cuboid — and replace it with time. At one end of the cuboid is the big bang. At the other is the very last moment of the universe. Maybe it's a big crunch.
The cuboid is filled with every event that ever happens. Where these events are in the cuboid represents their location in space-time. All events, including your birth and death, and this very moment as you read these words, exist somewhere in the block
