Episode notes

The chapter delves into the historical context of Newton's flaws leading to Einstein's development of special relativity, with a focus on predicting gravity's impact on space and time. It discusses Einstein's Nobel Prize win for his work on gravitational influence and the challenges in modern cosmology, including the Hubble tension and uncertainties surrounding dark matter and dark energy. The chapter also explores advancements like the Simons Observatory, the James Webb Space Telescope, and proposes the dark star hypothesis for early galaxies.

Is there a crisis in cosmology?!

Well, not exactly. You see, there’s not just one crisis in cosmology. There are many crises! But don’t worry, that’s a good thing. Crises are what scientists live for!

And what a time it is to be a cosmologist. We are at the forefront of uncovering the universe’s greatest mysteries, and we get to play with cutting-edge technology!

Recently, I got to share this passion of mine with Abhijit Chavda’s audience on his incredible show. We discussed the new and exciting breakthroughs that have been making headlines recently. But we also dove fearlessly into some of the most fundamental questions in cosmology that have been agitating the minds of thinkers for centuries.

It was delightful to discuss the current state and future of cosmology. I hope you will enjoy it as much as I did!

Tune in.
