How do physicists understand quantum mechanics? What are the postulates and principles of quantum mechanics? How do the foundations of quantum mechanics compare to other theories?
Where does quantum theory fit in the larger tapestry of physics? What is the domain of quantum mechanics? And most importantly, what are the limits of quantum physics?
How do you make a super-atom? What can they be used for? What does this mean for quantum mechanics? I discuss these questions and more in today’s Ask a Spaceman!
What makes the principle of least action so important? Who came up with it? Is it all just a bunch of math or does it actually mean something?
What is a pulsar? How can we use them to map gravitational waves? What kind of technology does it take? I discuss these questions and more in today’s Ask a Spaceman!
What are some of the problems with dark matter? What about modified gravity? Are there any other solutions? I discuss these questions and more in today’s Ask a Spaceman!
How big can a rocky planet get? Can a rocky planet turn into a gas giant? Why are some planets rocky and others gassy? I discuss these questions and more in today’s Ask a Spaceman!
How do giant black holes shut off star formation? How do they turn it back on? Which came first, the black hole or the galaxy? I discuss these questions and more in today’s Ask a Spaceman!
How did gravity get so ridiculously weak? Could it be related to extra dimensions? What does string theory and the concept of the “bulk” have to do with it?
What is the dipole repeller? Why is it a dipole? What is it repelling? What is the Bootes Void and how is it connected to dark energy?
