Clickbaity title. The estimated time until Higgs field decay has been changed from 10^794^ years to 10^790^ years. Presumably there's some tiny chance of it happening today, but practically we can just continue worrying about all the regular stuff that is about to kill us all.

Also, from what I understand, we wouldn't see it coming (as the decay would be spreading at the speed of light), and everything would be over before our senses could ever detect anything out of the ordinary.

So, if I'm reading it right, everything would just rip apart at the speed of light due to a change in mass because of the Higgs field transitioning to a lower state?

ugh i was hoping it would be before this election

[โ€“] [email protected] 18 points 1 month ago (2 children)

That's a huge difference, the estimate became 10,000 times smaller.

[โ€“] [email protected] 19 points 1 month ago (3 children)

It is, but there are still quite a lot of zeros left.

[โ€“] [email protected] 12 points 1 month ago

Itโ€™s like if I became 10,000 times less attractive. Same thing.

[โ€“] [email protected] 5 points 1 month ago

Is it more than 3?

[โ€“] [email protected] 2 points 1 month ago

it's still a concern for biden

[โ€“] [email protected] -5 points 1 month ago (1 children)

Its more like 0.5% difference.

[โ€“] [email protected] 5 points 1 month ago

Not really, the new value is 0.0001% of the old.

Just because the number has barely fewer digits doesn't mean it's barely smaller

we'll find out who was right then

Thank god

10^790 years

Which looks like I just held ctrl+v until it seemed suitably silly.

the question is whether you actually did that but i can't be fucked to check it

[โ€“] [email protected] 4 points 1 month ago* (last edited 1 month ago)

I was going to say it's way shorter than it should be, but then I realised Alexandrite renders it wrong and it spills under the community info tab and presumably far beyond the edge of my monitor.

[โ€“] [email protected] 8 points 1 month ago

So close yet so far

[โ€“] [email protected] 3 points 1 month ago (1 children)

Well, I guess we'll still end first

[โ€“] [email protected] 2 points 1 month ago

Vermin doesn't end. Even if you exterminate it, they'll just come back with a vengeance

Kurzgesagt has a nice video on vacuum decay for anyone interested

I'm a bit curious as to what time span exactly they're measuring here? Because it's not like the whole universe would die all at once. Heck, vacuum decay could have already begun somewhere. If so, it would propagate outward at the speed of light, which is quite slow compared to the size of the universe. If it's far enough away, it may never reach us at all due to the space between expanding.

In any case, this is all theoretical and may not be an actual thing that could happen at all.

[โ€“] [email protected] 19 points 1 month ago* (last edited 1 month ago)

There is a theory which states that if ever ~~anyone discovers exactly what the Universe is for~~ the false vacuum state collapses, it will instantly disappear and be replaced by something even more bizarre and inexplicable.
There is another theory which states that this has already happened.

God I can't wait.

โ€œIn the beginning the Universe was created. This has made a lot of people very angry and been widely regarded as a bad move.โ€

Time to end it! Inโ€ฆ.how many years, you say? sigh

[โ€“] [email protected] 8 points 1 month ago

Donโ€™t threaten me with a good time, like the universe ending tomorrow. God, this timeline sucks so much.

[โ€“] [email protected] 8 points 1 month ago* (last edited 1 month ago) (2 children)

Particle masses would change, along with all associated physics, as suddenly the lower Higgs field state means that everything has significantly more mass. To say that it would shake up the Universe would an understatement.

would this be enough extra mass to overcome dark energy expanding the universe and cause a Big Crunch? or would everything be far too spread out at that point for gravity/mass to matter at all?

[โ€“] [email protected] 6 points 1 month ago

Quantum field theory conserves mass-energy, so the new mass is coming from the energy in the Higgs field itself. It settles to a lower energy state and basically transfers that energy as mass to all of the particles that couple with it. Since it's mass-energy and not just mass that generates gravitational distortions, the large-scale gravitational evolution of the universe probably won't change, as this just moves things around a bit. It's not creating energy out of nothing.

[โ€“] [email protected] 3 points 1 month ago

maybe its what Hawking describes as epic sheets of force bigger then the universe slapping together to create the big bang and how it is probably not the first big bang

[โ€“] [email protected] 6 points 1 month ago (1 children)

So... Not tomorrow then. Meh, who cares.

[โ€“] [email protected] 5 points 1 month ago

That could solve a lot of my problems.

Of course, this expected time-to-decay has only shifted from 10^794^ years to 10^790^ years
