It never would have occurred to me that we could have telescopes capable of seeing a change in redshift of a galaxy over time as the univeral expansion accelerates. That's mind-boggling.
Can we see the expanding Universe changing?
#AskEthan
We've measured the expanding Universe by looking at many objects at different distances and with different redshifts.
Here's how we'll measure it directly: with just one object over time.

The Universe is expanding, the expansion is accelerating, and some galaxies even recede faster-than-light. Can we see a change in real time?

Christina Hunger is a speech pathologist who taught her dog, Stella, to communicate in English by pressing buttons. Sentences like STELLA WANT PLAY BEACH. Her book, “How Stella Learned to Talk,” is a fascinating read. I think she would be a great Mindscape guest 🙂

There aren’t any emojis with enough tears for this one. The world has truly lost a source of light, hope, integrity and decency. I can’t think of enough ways to honor her memory.

Hey! I wanted to re-watch the excellent talk you gave outlining 14 independent phenomena supporting the existence of dark matter. I think you gave it at a Canadian philosophical institute. I can’t find it. Has it been taken down from YouTube?

Going back and listening to old Mindscapes. So far, my favorite episode is the one with Cari Cesarotti. I knew nothing about muon colliders (yet to be), and it was fascinating. And her enthusiasm was captivating!

I’d enjoy hearing a Mindscape episode on mirror bacteria and reversed chirality in general.
Excellent podcast! Been going back in time (impossible, I know) and listening to older episodes. Best thing on the internet! Thank you!
