    Does Axionic Dark Matter Fuse Galaxies Together?

However, there are some fringe cases where its distinct features manifest on scales we can observe—in things like superfluids, or the interiors of collapsed stars. But it’s also possible that our entire galaxy is filled with a reverberating quantum mechanical wave that literally holds the galaxy together—and in fact explains all the dark matter that we see across the universe. And this isn’t even a fringe theory. It’s axionic dark matter.

Previous Episode: The Misunderstood Nature of Entropy https://www.youtube.com/watch?v=kfffy12uQ7g Entropy is sometimes described as a measure of disorder or randomness. The second law of thermodynamics – the law that entropy must, on average, increase – has been interpreted as the inevitability of the decay of structure. This is … misleading. As we saw in our episode on the physics of life, structure can develop in one region even as the entropy of the universe rises. Ultimately, entropy is a measure of the availability of free energy – of energy that isn’t hopelessly mixed in thermal equilibrium. Pump energy into a small system and complexity can thrive..

Dark energy AND dark matter? Who can remember which is which. But perhaps one astronomer has just fixed it, with a theory that says perhaps actually they are they same stuff.

And it’s pretty wild: negative mass particles continuously popping into existence between the galaxies. This rather extravagant claim resulted in a hysterical response from the media. Our viewers’ perfect blend of bright-eyed curiosity and cynical skepticism led to many MANY requests for us to do an episode on this new result. You got it. Today on Space Time Journal Club, let’s pick apart J.S. Farnes 2018, “A unifying theory of dark energy and dark matter: Negative masses and matter creation within a modified Lambda-CDM framework”.

    What Caused the Big Bang?

    PBS Member Stations rely on viewers like you. To support your local station, go to: http://to.pbs.org/DonateSPACE ↓ More info below ↓ Check out the new Space Time Merch Store! https://pbsspacetime.com/ Support Space Time on Patreon https://www.patreon.com/pbsspacetime Every astronomy textbook tells us that soon after the Big Bang, there was a period of exponentially accelerating expansion called cosmic inflation. In a tiny fraction of a second, inflationary expansion multiplied the size of the universe by a larger factor than in the following 13 and a half billion years of regular expansion. This story seems like a bit of a … stretch. Is there really any mechanism that could cause something like this to happen? What what we’re covering today – the real physics of cosmic inflation. Hosted by Matt O'Dowd Written by Matt O'Dowd Graphics by Leonardo Scholzer Directed by Andrew Kornhaber Produced By: Kornhaber Brown Dark Energy Playlist: https://www.youtube.com/playlist?list=PLsPUh22kYmNA6WUmOsEEi32zi_RdSUF4i The Quantum Vacuum and Hawking Radiation Playlist https://www.youtube.com/watch?v=OvgZqGxF3eo&list=PLsPUh22kYmNAHB1W2_Ka2F83sObdczwKr Most cosmologists buy some variation of the inflation hypothesis. It seems to very neatly solve some of the biggest questions in cosmology. Those being: why is matter and energy so smoothly spread out across the entire observable universe? And why is the geometry of the universe so flat? Neither should be expected unless the universe expanded much more rapidly early on. We explored these problems in an earlier video – worth a look if you really want to get inflation. Another problem fixed by inflation is the absence of magnetic monopoles – strange particles predicted to have been produced in the early universe. We’ll come back to those another time.

When we think of an exotic state of matter we tend to think of the really weird things that matter can do in extreme circumstances - like how at very high temperatures we get the plasma that the sun is made of, or at extreme densities we get the nuclear matter of neutron stars. But there’s one state of matter - supercritical fluid - that’s not solid, liquid or gas, but is also not confined to extreme or rare environments. In fact, there are planets in our solar system completely covered with oceans of the stuff, and you’ve often been the beneficiary of its powers without even knowing it. Special Thanks to Nigel Braun.
