Why the Universe's Expansion Doesn't Make Sense

What this episode covers

The Hubble tension problem is breaking cosmology. Cosmology is in crisis. Scientists have argued for decades about how and why the universe is expanding. Now, after careful measurements using multiple methods, the main two don’t add up. What do we do when our measurements of the universe don’t match up with our models? Are all of our theories wrong?▀▀▀▀▀▀If you love learning about science as much as I do, head to http://brilliant.org/astrum to start for free.

Bauer, Florian Schneider, Axel Weber & Dr. Tillman Bardt The Newmorrow PodCast is more than a podcast — it's a platform for open dialog on the future of our business, a platform for those building what doesn’t exist yet. Here, we share and embrace our passion for the hospitality industry, but we won’t romanticize the journey. We ask the tough questions, confront uncomfortable truths, and prepare for a future that resists easy answers. We believe that the tougher and wilder times become, the more openly, honestly and humanely people need to talk to each other and act together. We believe, openness, togetherness, and truthfulness should also be cornerstones of a professional community to develop our utopian idea of „open source“. This is a space where visionaries don’t just imagine the future — they wrestle with the paradoxes that shape it: success vs. happiness, data vs. instinct, stability vs. reinvention. Join leaders, entrepreneurs, and thinkers as they share not what made them — but what’s actively shaping them, now and next.
