Do you want to build a snowman? Do we live in a hologram? Why don’t we understand gravity? How big is the universe? Find the answer with @PaulMattSutter at #365DaysOfAstro
Could we live on Mars? Could we have a telescope big enough to spot cows on another planet? Does time stop inside a black hole?,
What does ‘time’ mean for light? What is the real lesson of the twin paradox? How can we all agree on the true age of the universe? Why is it all so technical?
@PaulMattSutter interviewed Dr. Emily Holt and talk about prehistoric and historic cultures, how they used astronomy, and how we know about it!
How and when did we realize that atoms exist? How did we learn to understand their properties? How was Ernest Rutherford hogging all the science for himself? find the answer here at #365DaysOfAstro with @PaulMattSutter
How hot was the cosmic microwave background? Do gravitational waves travel at the speed of light? How do we understand cosmological redshift?
