Astrum Space · We Thought It Was Impossible, But We’ve Finally Seen It · 31 Aug 2026 podcast

The latest breakthroughs in observing filaments lend important evidence and support for our current standard model of cosmic evolution, known as the Lambda Cold Dark Matter model. voice-verified

The model is underpinned by dark matter, which has been too complicated for us to catch a glimpse of thus far, so observing this once thought missing visible matter on the cosmic web is a big step in the right direction. voice-verified

But to truly know whether our models match reality, we need more than one or two filaments. voice-verified

We need to map the entire skeleton, or at least much more of it. voice-verified

And that is where another mission, Euclid, comes in. voice-verified

Launched in 2023, He says Euclid mission is designed to piece together a more accurate picture of the cosmic web's structure and history, and dig into the nature of dark matter and dark energy. voice-verified

Euclid will help us measure galactic shapes with precision, revealing how dark matter distorts space through gravitational lensing and measure redshifts, giving us a 3D position for each galaxy. voice-verified

This combination will allow Euclid to infer the locations of the dark matter filaments, not just the galaxies on them. voice-verified

and give us precise locations to look for more gas. voice-verified

By 2030, Euclid will likely be able to confirm if the cosmic web matches results from the XMM Newton filament discovery. voice-verified

And the pattern seen in the cosmic microwave background is voice-verified

If it's a perfect match, that would be one of the strongest confirmations of the Big Bang model in the history of science. voice-verified

If not voice-verified

Then something is fundamentally missing in our standard model. voice-verified

Whether it's our understanding of dark matter voice-verified

Gravity or the early universe. voice-verified

Either way, with the help of Euclid and the latest observations of these cosmic filaments, cosmology is poised to be changed forever. voice-verified

A massive thank you to our astronauts on Patreon. voice-verified

This video had no sponsors, but it was still made possible thanks to the hundreds of members we have there. voice-verified
