Paper Boys

Episode 47

How can you measure the expansion of the universe?

...and how do you even start to measure it?

In the early 20th century, Einstein, Hubble, and other scientists confirmed the universe was expanding. With the exception of a few nearby galaxies, nearly all galaxies are moving away from us. Scientists have long been tempted by the challenging problem that arises from trying to measure how fast these galaxies are moving away, resulting in some fascinating findings. It turns out that by measuring the gravitational waves from colliding neutron stars, we might just find a better answer! Join us this week as Charlie dives into new research that improves humanity’s (and the Paper Boys’) understanding of our ever-expanding universe.
