Our series on Universe weirdness continues, this time we learn how astronomers are struggling to make sense of the age of the Universe.
Astronomers have been trying to accurately measure the expansion rate of the Universe. It’s been tough to nail down, and now astronomers are starting to figure out why.
What’s it like to fall into a black hole (again)? What does the outside universe look like?
This week we wonder if the Universe is going to collapse and then expand again, how satellites can have such different velocities, and the size of the observable Universe.
Our universe is 13.8 billion years old,. How do astronomers arrive at such an enormous number? more with Sabrina @qdteinstein @quickdirtytips at #365daysOfAstro
What is chaos theory? How can something be both deterministic and unpredictable?
What’s the deal with redshift? How can we actually interpret velocities when it comes to cosmic expansion?
