Combined observations from Chandra (purple), the Very Large Array (yellow) along with Hubble (red, green, and blue) have provided astronomers with a detailed new look at how galaxy and black hole formation may have occurred in the early Universe. The lack of a significant bulge of stars in the center of Henize 2-10, a galaxy with similar properties to those when the Universe was very young, indicates that black hole growth may be preceding the growth of the bulge. This differs from the relatively nearby Universe where the growth of galaxy bulges and supermassive black holes appear to happen in parallel.

About This Episode

Is gravity fundamental to the universe? Neil deGrasse Tyson and Chuck Nice explore quantum physics, the fourth dimension, whether H2O is water, and the many-worlds interpretation with theoretical cosmologist Janna Levin, PhD.

Is space infinitely elastic? If spacetime is a particle at the smallest scales, is there space between spacetime? We get philosophical: is H2O water? We explore the quantization of space, Planck lengths, and whether gravity is an emergent feature of quantum physics. Is gravity a fundamental feature of the universe?

What would you see in the earliest parts of the Big Bang? We explore how you could rewrite relativity as particle field theory and the geometry and topology of the universe. Learn about the time Einstein let his driver give a talk for him and how the 1919 eclipse changed physics forever.

We break down the fourth dimension, compactifying space, and Lorentz boosts. Do physics and math view spacetime differently? Neil and Janna discuss the many-worlds interpretation and whether it’s trying to make classical sense of something non-classical. Plus, we explore how quantum teleportation would work. Is the universe in a superposition? Are black holes fundamental particles?
