What is the Fermi Paradox?

The Fermi Paradox, first proposed by physicist Enrico Fermi, addresses the question, “where is all the intelligent life in the universe?” It might seem that the answer to this is obvious; life is incredibly rare. But let’s just run a few numbers anyway. The low-end estimate of how many stars are in just in our […] Continue reading Continue reading

Nuclear Fusion in the Sun

At the core of the Sun, and every other Sun like star, a process called fusion takes place. Fusion describes a process where light elements, such as hydrogen, get fused together to form heavier elements, like helium. Fusion happens due to the intense pressure of gravity acting on the suns mass. A byproduct of this […] Continue reading Continue reading

What’s the deal with black holes?

(Artist’s depiction of a black hole “stealing” mass from a nearby star) What are black holes? Black holes are supermassive cosmic objects. They can be very large or as small as an atom. These atom-sized black holes are so massive that, if on Earth, they could have the same mass as a large mountain. Super […] Continue reading Continue reading

Gravitational Waves Confirmed

Picture and Video Explaining Gravitational Waves Thursday February 11th 2016 was a monumental day for physics. Albert Einstein first theorized gravitational waves in 1916 as part of his theory of general relativity. Gravitational waves are ripples in the fabric of the universe caused by massive cosmic events, such as the collision of black holes. These ripples […] Continue reading Continue reading
