Discovering Dark Energy and the Hubble Tension with Adam Riess
Q: What is the Hubble Tension?
The Hubble Tension refers to the growing mismatch between the expansion rate predictions from the cosmic microwave background and local measurements.
Discovering Dark Energy and the Hubble Tension with Adam Riess
Q: What are the possibilities for describing what dark energy is?
Einstein's cosmological constant remains the simplest interpretation, though we have models that suggest it could also be temporary energy or alternate theories about gravity.
Discovering Dark Energy and the Hubble Tension with Adam Riess
Q: What is dark energy?
Dark energy could be stuff in space-time, acting with repulsive gravity to expand space-time more rapidly.
Discovering Dark Energy and the Hubble Tension with Adam Riess
Q: Did you believe it?
Initially, I don't think you ever believe something in the beginning. In science, you make so many mistakes before building trust in the results you see.
