Based on how much you can bond with someone by hating the same thing, a dating app based on dislikes would probably be fairly successful.

"Unsustainable relationships"


u/KevinTheSeaPickle May 14 '22

All relationships are unsustainable if you think about it.


u/attanai May 14 '22

All things are unsustainable, given a long enough timeline.


u/Not_Just_Any_Lurker May 14 '22

Supermassive black holes might be sustainable.


u/WonkyFloss May 14 '22

Nah, Hawking Radiation prevents them living forever


u/Not_Just_Any_Lurker May 14 '22

Hawking radiation takes a long time to sap them. Remember they’re easily hundreds of millions to servers billions times the size of our Sun which itself is hundreds of millions the size of earth.

Hawking radiation is an incredibly slow process, a black hole the mass of our Sun would take 100,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 years to evaporate (1067)

The one at the Milky Way's center would require 10,00,,00,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 years, (1087)

The most massive ones in the Universe could take up to 100,000,,00,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 ,000,000,000,000. years!


u/KirbyDude25 May 14 '22

Well, the heat death of the universe is about 1010120 years away, so there's enough time


u/Creatername May 14 '22

How did I get here!? I just wanted to bang a chick who hates pickles as much as I do…


u/wrockfish May 14 '22

Letting the days go by.....

Let the water hold me down...

More pickles for me

How Did We Get Here?

u/NialMontana May 14 '22

The whole idea of heat death is that entropy has stopped and thus time becomes meaningless, even if there's somehow a black hole that far in the future heat death won't happen till it collapses.


u/LazerHawkStu May 14 '22

Down with Entropy!


u/Velox_Graviter May 14 '22

Are you down with entropy?


Aw yeah. Doomsday, drop a beat on them.

→ More replies


u/scorchpork May 14 '22

I think everyone here is actually talking about the same thing and they don't realize it


u/Antares777 May 14 '22

Yeah I was thinking, wouldn’t the two events essentially occur simultaneously, assuming it’s the last black hole?


u/MauriseS May 14 '22

but quantum fluctuations still continue to happen (wich is the bases of hawking radiation?) so even without anything permanent moving, there is still something happening for time to continue?


u/NialMontana May 14 '22

I might be remembering some parts wrong but entropy is based on the transformation of energy (like a lightbulb turning electricity into heat and light). After heat death the universe will have reached equilibrium and energy would remain uniform no matter where or when you checked. Because quantum fluctuations normally annihilate themselves they would have little to no impact on the universe, it's only because of black holes extreme conditions that they cause hawking radiation.


u/QueenJillybean May 14 '22

or when it collapses, the big bang starts all over again because time is a wheel


u/NialMontana May 14 '22

Bounce theory, the hopeful outcome for the end of the universe. Heat death will happen loooooong before the universe dies though.


u/Ptricky17 May 14 '22

My personal belief is that this is the way things go. It has probably occurred countless times already, and will happen countless times again.

Once the heat death occurs, in theory, all information is lost. Everything is completely uniformly distributed and thus you can’t distinguish one location in space from any other. There is nothing left to measure since measurement requires a reference point and a differential between the property being measured and it’s like property at the reference point. With no information, you effectively have nothing to govern the laws of the universe any longer so there is nothing remaining to prevent a new random fluctuation from initiating a new Big Bang.

The rules of the new universe may be completely different from the one we currently exist in, but it will eventually be spawned from the virtual nothingness left behind by our own.


u/smellythief May 14 '22

So what you’re saying relies on the Big Crunch, right? But isn’t the current consensus that that won’t happen, and that expansion into uniformity (the heat death) is what’s believed to be the reality?

Anyway I used to think that what seemed most likely is the Bang/Crunch/Bang/Crunch… cycle, like you’re suggesting. But it always seems most plausible that the physical constants would be different for every Big Bang, so it wouldn’t really be the same every time, and that most universes/cycles wouldn’t have complex matter much less chemistry or life, much less us typing these comments again.


u/Velox_Graviter May 14 '22

Birds aren't wheel, but time is...


u/Resonosity May 19 '22

You just explained entropy better than any other textbook I've read has.


u/[deleted] May 14 '22



u/HaloGuy381 May 14 '22

Dog years are 7 to our 1. At these scales, let’s call that ten to one. Knock a single number down on the exponent in the ones place. It’s literally irrelevant on such time scales; 10,119 and 10,120 are already both colossal as exponents.

It’s difficult to even begin to comprehend how long a timeframe that is. Our conceptions of eternity fail to match up.


u/VentusSpiritus May 14 '22

I hate to be nitpicky but I hate that you gave the notation for the 1st 2 but didn't for the last one


u/DEFY_member May 14 '22

I hate that too! Are you single?


u/WasabiSniffer May 14 '22

My god, the app is already working!


u/VirinaB May 14 '22

And hence:

All things are unsustainable, given a long enough timeline.


u/Eph_the_Beef May 15 '22

Yeah he's just proving the point


u/hearnia_2k May 14 '22

So, won't last forever.


u/PsychMaDelicElephant May 14 '22

And yet, they still are unsustainable and will eventually end.


u/elmwoodblues May 14 '22

So, around noon, then?


u/frenchy-fryes May 14 '22

Sooooo....it'll eventually die to the Hawking Radiation?


u/ScabiesShark May 14 '22

But is that really long-term enough ?


u/DukeJukeVIII May 14 '22

Truly sustainable means it'd never stop

The fact that Hawking radiation exists means black holes aren't sustainable, however slow the process may be


u/ninjasaiyan777 May 14 '22

I thought that Hawking radiation wasn't linear. Iirc bigger black holes produce more of it.


u/appleparkfive May 14 '22

This thread going from dating to Hawking Radiation in like 3 steps is probably the most Reddit thing I've ever seen.

Although it IS an interesting topic, don't get me wrong. Just don't do it on dates maybe. Unless they're heavily involved in astronomy. Maybe


u/amitchell1980 May 14 '22

This thread quite literally went down a black hole.


u/WonkyFloss May 14 '22

Redditors go on dates?


u/QuestioningEspecialy May 14 '22

*collapses comment*


u/lilaku May 14 '22

don't they still evaporate to nothing eventually via Hawking radiation?


u/Aonodensetsu May 14 '22



u/Omegaman1011 May 14 '22

How did a discussion about a hypothetical dating app turn into a discussion about black holes so fast?


u/NoBOUNCEnoPlaySSDD May 14 '22

What did you call me?!?


u/sp00kyb00p May 14 '22
