Aug 3rd: What’s So Groovy About Gravitational Waves?
What are gravitational waves? What makes them? How can we detect them here on Earth, and why is it a big deal? I discuss these questions and more in today’s Ask a Spaceman!
May 24th: Skipping Through Time
Have you ever wanted to be a time traveler? Well, good news! You’re time traveling right now. Into the future at one second per second. Today, let’s talk about the weird world of time dilation.
Jul 1st: Everyday Relativity
Relativity is used in more day to day situations than you may realize. In this episode, we will count (some of) the ways.
Jun 8th: 100 Years Since the Eddington Experiment
Einstein published his general theory of relativity in 1915. Four years later, Arthur Eddington led and experiment to observe the deflection of starlight during a total solar eclipse providing critical evidence supporting Einstein’s Theory. Nearly 100 years later, a team of astronomers and students is attempting to recreate his experiment in Chile during a total solar eclipse on July 2nd.
May 29th: The Centennial of the Eddington Eclipse Expedition that Tested Einstein’s General Relativity
To test Albert Einstein’s prediction, with his General Theory of Relativity, with observations from the total solar eclipse of May 29, 1919, observers led by Arthur Eddington went to Principe.
Apr 17th: Seriously, what is gravity?
How did Einstein develop General Relativity? What does it mean for different kinds of masses to be equivalent? How does gravity do what it does?
May 15th: Einstein’s Theory of General Relativity
The great scientist made an even more profound impact on physics with his theory of general relativity, replacing Newton with a better model for gravity.
