There’s something crazy going on in the world of physics right now. According to new data from the Dark Energy Spectroscopic Instrument (DESI), the cosmological constant might not actually be constant, rather, it is decreasing and had a “phantom crossing”. What does that mean? I have a quick summary of what’s new.
Correction to what I say at 4:30 — The "Big Rip" requires dark energy to grow not just stay constant, I said this badly.
