Is Dark Energy Decaying?

Brian, I have to say we find this model superior to the usual group discussions. Besides the personal details and anecdotes, it comes across with better discussion of the core science. Keep up the good work!

BRIAN GREENE BEEN DROPPING NEW VIDS EVERY FEW DAYS AND ITS AMAZING

"Did I say anything smart"? Totally relatable 😅

What a fantastic conversation. Especially the part around the experimental design and challenges. Michael Levi's passion & excitement was so palpable.

lets give out props to the engineers

Always enjoy professor Greene's world science festival. I'm absolutely intrigued by the subject. Though it's 2.5σ it's enough to go forward for further investigation. Finding the answer is most important... BC those answers shall create more questions. Which is the fun part.

I knew that I knew very little when I got here. After watching I realized I knew less than what I thought I knew. That's when you know your've learned something.

Listening to Mr. Levi describe the engineering of a modern telescope -- collecting a few thousand precious photons from galaxies thousands of light years away -- I sat there with my mouth hanging open in genuine awe before I realized that I hadn't done anything but listen and think and marvel in a full ten minutes.

19:30 -- This idea that lead into 'SNAP''(Supernova Acceleration Probe) & what it has grown into now, is incredible to say the least. On top of that, building these ~cameras that watch the cosmos, is even more incredible..

Hovering over the thumbnail for this video is pretty entertaining.
