[@JeremyNasmith]

And that new Axe-thingy was forged by Tyrion Lannister. Would a spinning object's rotation slow down if matter is removed though? That implies it'd speed up if matter were added and that seems backwards to me. if F=ma, for a to be growing, a= F/m so either F has to grow, or m has to shrink. (I know, I'm not using the equation for moment of inertia vs torque, but for this general argument that losing mass ought to increase rotation, f=ma is good enough.)

Hearing about news like this makes me feel that sometime in my lifetime, a breakthrough discovery will be made that shifts our understanding of the universe, so as to make everything fit into a single congruent theory. Or what do I know, maybe more questions then answers will be made. Either way, it is exciting stuff.

[@Thuazabi]

You'd be surprised at how often it's both. Often times we rise to the peak of one level of understanding, only to realize once we've done so that there's a greater peak to ascend to. Just look at what happened between the late-19th and early-20th centuries. We basically closed the door on classical physics and mechanics and moved onto the relativistic and quantum realms. I have a feeling that a fully fleshed-out and proven theory of quantum gravity is going to be the gateway towards the next paradigm shift in moderns physics, not an endpoint.

[@lillie1875]

Edit: I too am confused about how he said they're cold? I missed that on first viewing. Neutron stars are very hot, as they are the leftover remnants of a supernova explosion. So a neutron star is just the dead core of a star that will slowly radiate away all of its heat. Edit for facts: neutron stars have a temperature of about 1000000 Kelvin or 17999540.3 degrees Fahrenheit, so yeah very hot They also have masses that can range from 1.4 solar masses to 2.16 solar masses, any larger and neutron degeneracy pressure will be over come and gravitational collapse will occur and create a black hole.

Wait but if a neutron star typically has a surface temperature of 600000K how can the core be so cold that its a superfluid...? Or is it a super fluid because of the very high pressure from high gravity? I guess if you packed them that closely together it could do the whole many particles acting as the same particle trick, as though it were very cold? Unless a sea of dense neutrons spinning very fast has some really weird thermal transfer properties which yeah I guess it would...

So clickbait? Dark Matter in the new hypothesis simply formed earlier but not before the actual start of things.

[@RequiemPoete]

Not true. A Big Bang is considered the start of time, because the state it existed just before was infinitely dense. Entropy can't happen in such a state so what we concieve of as time doesn't exist. So if a previous Universe had a Big Crunch and contracted to a singularity, time essentially stops as matter converts back to pure energy and space and time collapses. So, for Dark Matter to be survivors of this previous Universe means it existed before time. Hell that might be why we can't see it. There would be no guarantee the previous Universe operated with the same fundamental physical laws that ours do. The gravitational constant, might have been different or Light Speed could have been slower or faster. So Dark Matter might not be interacting correctly with our laws.

It turns out that isn’t what the title is claiming, and most people were likely mislead by the title. Hence, clickbait.

I remember one of my professors had a sign that said something like 'we cannot hope to think that we are filling gaps in our knowledge, rather than we are making gaps in our ignorance.' In fact, I think knowledge is fractal. Every time you delve deep into a topic, you open up a whole new series of questions just as vast as all the questions your efforts just answered. Continually and forever. Which is actually kind of exciting.

After matter succumbs to heat death, does it still exert a gravitational pull?

[@papagrounds]

My own theory is that there's is no dark matter and never was. It's just the lack of understanding how the gravity really works.

[@AverytheCubanAmerican]

It all started with the big bang, BANG!

[@thstroyur]

Then it lasted for a few seasons, but ultimately it couldn't avoid the Big Crunch from the network

[@tofolcano9639]

I would have never guessed that neutron stars were are actually cold

[@sMASHsound]

how does matter moving outward cause the outer shell to speed up? it would more logically slow down. also, how does the inner core move out? isnt there more gravity than inflative energy? unless, it looses some amount of gravity, and there is a brief imbalance of gravity/energy, causing it to expand somewhat. all i can think of, there is still some dynamics in there, and it there is a bit of rebounding going on, and every so often u get positive inteference across the whole object not unlike a rogue wave. and then it moves out a bit, then slowly resettles, contracts and speed up.

[@neoh524]

Dark matter and dark energy are fairy tales, as well as the Big Bang for that matter, no pun intended. #plasmauniverse

[@RazorBaze]

Inflation was after BB. Whatever one defines it. So, the title is completely misleading.

I love this guy

[@deluxeassortment]

I always had this concept of the big bang that the singularity was just sitting there, minding it's own business, when something else came along and swung around it, and the resulting dance ripped both apart. What does it take to expand a universe sized singularity?

[@sebastianelytron8450]

So the Big Bang was like your mom switching on the lights to wake you (the universe) up?

[@CoastalEddieinflames]

Observer effect?

[@Zeed_316]

The more we learn about dark matter, the more I'm convinced that it's actually cthulhu jizz.

[@shartbake1134]

Reminds me of spinning an egg, it will quickly lose balance and slow down.

[@ChemicalChrisOttawa]

Per Dark Matter, this recent (and easy/fun to watch) interview with Roger Penrose discusses this a bit. Barely. Talks about Hawking points (blackholes from previous universe), mentions that Dark Matter would be expected in our universe. Doesnt discuss more, but I'd love to hear/learn! EDIT: The interview kzbin.info/www/bejne/b3jPaaOtjpeejZo Cheers

[@nguyetlam946]

💥 from a neutron star. ya got a QUARK star

[@NewGoldStandard]

It will be nice when we finally understand ourselves.

[@chris210]

I hope you guys will be covering the pre-big bang star paper at some point

[@Chareidos]

What paper, may I asked? I may heard of it, but can't find it!

[@leonreynolds77]

I've already pondered the idea that dark matter could be what is left of a previous universe that we can not peer into. It may be matter just like our matter but we can not interact with it in any way and from it's perspective, we are invisible to it.

[@conqurr]

it wasnt just miumiu , it was stormbreaker too.

[@free_spirit1]

This episode was intense

[@SernasHeptaDimesionalSpace]

in the cold or hot side of the neutron star of course?

[@sarahs3832]

In one of the pictures, it says superfluid protons, but in the other it says superfluid neutrons
