Some people worried that the large hadron collider would smash particles together so hard it would make black holes that would swallow the earth, open wormholes to other dimensions. It didn’t and won’t. But it may be making a different kind of portal. A portal to the dark sector. This isn’t the Rather, it’s a hypothetical family of elementary particles that exists in parallel to the familiar particles of the standard model, but are invisible to it. Invisible to us, and so could be the answer to the dark matter conundrum. And what is this portal? It’s the particle that the LHC was built to find in the first place – the Higgs boson.

We Timed a Cosmic Explosion. It Might Solve Dark Energy.
Get a special 35% discount on an annual digital subscription to The Economist at https://www.economist.com/PBS
We’ve known that the universe is expanding since 1929, and that its expansion is accelerating since 1998. The culprit behind the acceleration is unknown, so we live with a stand-in term “dark energy”. Our modern cosmological model assumes that dark energy has a constant density–always the same amount of the outward-shoving stuff per volume. But there’s recent evidence to the contrary–which may be why our primary efforts to measure the expansion rate of the universe disagree with each other.

Physicists have long believed that detecting the particle of gravity—the graviton—was fundamentally impossible, with the universe itself seeming to block every direct attempt. This episode explores a new generation of clever experiments that may finally let us detect gravity’s particle, and why even succeeding wouldn’t quite mean what we think it does.

The universe thrums with quantum fields; and the particles of matter and force emerge as vibrational manifestations of the deep symmetries of these fields. The layers and reflections of those symmetries give us the wonderful richness of what we call the standard model of particle physics. Except there seems to be something missing: the sterile neutrino.

The Universe Itself Might Be Hiding the Gravity Particle From Us
Head to https://brilliant.org/Spacetime/ to start learning for free for 30 days. Plus, our viewers get 20% off an annual Premium subscription for unlimited daily access to everything Brilliant has to offer.
To progress to the next level in understanding reality, we need to combine quantum mechanics and Einstein’s general relativity. And to do that, most physicists believe we need a theory of quantum gravity .. which means we need gravitons. But it also seems like the laws of physics make it impossible to ever detect this quantum particle of gravity. Almost like the universe is set up to keep the final answer forever out of our reach. So, can we outsmart the universe, catch a graviton, and finally solve physics?

Black Holes. Explained. For 1.5 Hours.
Black holes are not just the strangest objects in the universe, they’re the sharpest test we have of how reality actually works. This episode explores how these extreme cosmic laboratories force general relativity and quantum physics into direct confrontation. We look back through a decade of content to understand their formation and the theoretical diagrams that describe them, offering a journey through the profound implications of these celestial objects for our understanding of space time and astrophysics.

2025 is … was the international year of quantum science and technology. Yes because quantum tech is increasingly important, but especially because quantum mechanics was invented 100 years ago this year. In 1925, our strangest true theory went from being a peculiar set of ideas to describe some funny results from experiments, to a full-blown theoretical framework that overturned how we think reality really works. So today, as the centenary year approaches its end I want to take you on a little journey through what may be the most paradigm-destroying several months in scientific history.

There are lots of reasons to search for planets around other stars—exoplanets. A big one is to find other places in the universe that might harbor life. We only know of one such planet so far: Earth. And so we get particularly excited when we find Earth-mass planets at the right distance from their star to sustain liquid water—also critical for life as we know it. We’ve found lots of those “habitable” worlds. But we also don’t know what factors are really critical to the initial development of life. Maybe star type? We get even more excited if that Earth-mass at the right distance from a Sun-type star. We’ve found a few of those too, and we can infer that there are lots more.
