Pin-pricks in the celestial sphere, through which shines the light of heaven? Or gods and heroes looking down from their constellations? Or lights kindled above middle earth by Varda Elbereth and brightened with the dew of the trees of Valinor? Science has long pondered the mysteries of the stars. This is how we finally figured them out.

If you wanna make an omelet you gotta break a few eggs. And by omelet I mean a theory of everything, and by eggs I mean a billion billion subatomic particles obliterated in the next generation of giant particle colliders.

In June, the consortium of Europe’s top particle physicists published their vision for the next several years of particle physics experiments in the EU. A big part of that is the Future Circular Collider, which, if it happens, will accelerate particles in a 100 kilometer circumference underground ring encircling Geneva. It’ll be nearly 4 times the size of the Large Hadron Collider, and it would be capable of colliding particle beams with 8 times the current LHC energy. The hope is that this will open the window to brand new physics – and perhaps break the current deadlock in our quest for a theory of everything. But do the FCC or other upcoming collider experiments really have a chance of succeeding? Today we’re going to discuss the incredibly ambitious plans for future colliders, and try to honestly evaluate their prospects.

Our galaxy is full of dysfunctional stellar relationships. With more than half of all stars existing in binary orbits, it’s inevitable that many stellar remnants will end up in parasitic spirals with their partners. Today we’re going to look at the worst of these – from the novae produced by white dwarfs, to X-ray binaries created by neutron stars and black holes – and much weirder things besides.

The second in our two event series about Theories of Everything! Watch the first one: https://www.youtube.com/watch?v=_izocEgArtQ

Please subscribe to Brian Keating’s YouTube Channel to watch one-on-one interviews with the guest speakers and more: https://www.youtube.com/DrBrianKeating

Existing Theories of Everything have not yet produced experimental evidence that solves the fundamental challenges facing physics. That lack of progress has opened up a sea of controversy, from disagreements about the very necessity of TOEs, to questioning the cost/benefit of mega-billion dollar particle accelerators in search of them, to the emergence of competing TOEs from physicists outside of the academic community. In this 90 minute chat we dive into the existential questions around TOEs.

When we detected the very first gravitational wave, a new window was opened to the mysteries of the universe. We knew we’d see things previously thought impossible. And we just did – an object on the boundary between neutron stars and black holes, which promises to reveal the secrets of both.

The most precious substance in our universe is not gold, nor oil. It’s not even printer ink. It’s antimatter. But it’s worth every penny of it’s very high cost, because it may hold the answer to the question of why anything exists in our universe at all.

Black hole singularities break physics – fortunately, the universe seems to conspire to protect itself from their causality-destroying madness. At least, so says the cosmic censorship hypothesis. Only problem is many physicists think it might be wrong, and that naked singularities may exist after all.

Black holes are about the worst subjects for direct study in the universe. But at this stage, it’s all we can do to convince ourselves of their existence. Actually studying the physics of real black holes is much, much harder. I mean, we could try to make one – but that’s way beyond our current tech level, and also potentially humanity-destroying. Well it turns out we don’t need to make real black holes to at least get started with the lab work. We can instead study analog black holes – and by analog, I don’t mean old fashioned clockwork black holes – I mean analogies. Physical systems that aren’t black holes but that behave in similar ways – and may reveal the real behaviours of real black holes.
