Just How Fast is the Universe Expanding EXACTLY? …and how do we know this?
Apr 1 • 61 min
We’ve known since Edwin Hubble’s time that the universe has been expanding. What we’ve only recently learned (like, in the past 10 years or so) is that the universe is accelerating as it expands. Measuring this expansion rate has been problematic and…
Life in the Universe? We May Be It!
Mar 28 • 35 min
