The Cosmic Crisis | The Cosmic Crisis: Dark Matter, Hubble Tension, and the Failure of Lambda CDM

For decades, we’ve relied on a powerful theory to explain the universe: the Lambda CDM model. But now, we are facing a "Cosmic Crisis." From the Hubble Tension to the James Webb Space Telescope finding galaxies that shouldn't exist, our maps of the cosmos are fundamentally cracking.

In this video, we dive into the front lines of science to see why the search for the "WIMP" (the prime dark matter suspect) came up empty after 417 days in an underground gold mine. Is dark matter a particle we haven't found yet, or is it a "ghost in the machine" created by our misunderstanding of gravity itself? We explore the new challengers—from Modified Gravity to ancient black holes—and look at the next generation of space telescopes like Euclid that are fighting to solve this mystery.

In this video, we cover:

The Lambda CDM Model: The "ruling government" of cosmology and its 6 key numbers.

The Hubble Tension: Why the universe seems to be lying about its age.

The LZ Experiment: Why the world's most sensitive detector found neutrinos but NO dark matter.

James Webb Breakthroughs: How early "filament" galaxies are defying the standard model.

Modified Gravity (MOND): Could Einstein's theory of gravity be incomplete?

Mapping the Dark: How the Euclid Space Telescope is building a 3D map of the invisible scaffolding of space.
