Episode notes
Changing Dark Energy?
- New data from the Dark Energy Spectroscopic Instrument (DESI) suggests dark energy might be changing over time.
- This challenges the cosmological constant model, where dark energy is constant, and introduces the possibility of "phantom energy".
Euclid's Lensing Discoveries
- The Euclid space telescope has identified nearly 500 strong gravitational lensing candidates from early data.
- This data offers a new way to probe the distribution of dark matter and dark energy in the universe.
Amazon's Quantum Leap
- Amazon's new quantum chip, developed with Caltech, features built-in error correction.
- This approach might be more practical for scaling quantum computers than Microsoft's topological qubit.
