The Most Valuable Place in Space
While it might seem like there’s plenty of room in space, some pieces of celestial real estate are more valuable than others. As far as human space exploration is concerned, Lagrange points may be the most important places in our solar system. So what exactly are they?
The Battle that Formed the Universe
Explore what happened after the Big Bang and how the battle between gravity and pressure shaped the structure of our universe.
The Cosmological Boltzmann’s Paradox
How do you know you’re a person who has lived your life, rather than a just-formed brain full of artificial memories? That may sound absurd, but it’s kept several generations of top cosmologists up at night. They call it: the Boltzmann brain paradox.
Why the Sun could crash your internet
Explore the science of solar storms, and find out why they occur and just how prepared we are for a major event.
Want to go to space, but hate flying? Just take the elevator!
Explore the physics behind space elevators, which would theoretically use a cable anchored to Earth and extending into space.
Could we harness the power of a black hole?
Could we harness the power of a black hole, to forge a galactic civilization? Learn why black holes are extremely efficient gravitational engines.
Newton’s three-body problem explained
What is the three-body problem? Learn about this century-long problem and why it is important to understand the stability of our own Solar System.
Hawking’s black hole paradox explained
Where does quantum information go when it enters a black hole? Investigate the theories of the black hole information paradox.
Can a Black Hole be Destroyed?
Are black holes indestructible?
Explore the theory of Hawking radiation, a process that could lead a black hole to gradually lose mass and evaporate.
Could the Earth be Swallowed by a Black Hole?
What is a black hole? Where are they? How big are they?
