What Does A Theoretical Physicist Do?

How do you introduce yourself, scientifically? My name is David Kolchmeyer and I am a theoretical physicist. I’m interested in quantum gravity, which is a theory of gravity that obeys the rules of quantum mechanics. Quantum mechanics is the fundamental framework upon which much of my field is built. I’m most interested in the properties of black holes, which are a good system for studying quantum gravity. … Continue reading What Does A Theoretical Physicist Do?

Photographing the Darkest Objects in Existence: The First Image of a Black Hole

Black holes are super dense objects that hypothetically exist in our universe. They have a gravitational pull so strong that any object that gets close enough falls in and can’t escape, including light. These objects often have a mass tens to millions of times greater than the mass of our sun. While we have predicted their existence for a hundred years, only recently have scientists … Continue reading Photographing the Darkest Objects in Existence: The First Image of a Black Hole

Black Hole Burps: Particle Absorption and Emission in Supermassive Black Holes

Black holes are fascinating objects to study because we can use them to learn more about about astronomy, cosmology, and gravity. Black holes are super-massive and super-dense objects in the universe. Because of these properties, they produce strong gravitational and electromagnetic forces that suck nearby objects in. After ‘eating’ all this extraneous matter, the black hole has energy to spare and then ‘burps’, emitting high-energy … Continue reading Black Hole Burps: Particle Absorption and Emission in Supermassive Black Holes
