I love The Onion, and I love the A. V. Club articles they put out. These guys have a gift for talking about the raw matter of modern pop culture. If you're familiar with the A. V. Club, you know that their articles are not satire like The Onion; they are very similar to articles … Continue reading Are you from a parallel universe?
I invite you to do a little thought experiment with me, and you'll need a prop to help you along. Get yourself a sheet of paper. Draw an X toward one end and another X toward the other end. It should look something like this: I want you to imagine that the surface of this … Continue reading Wormholes and Quantum Entanglement: A Spooky Duo
Before I go any further, I must point out the difference between gravitational waves and gravity waves. Gravitational waves are waves that occur in the fabric of spacetime created by gravitational phenomena in a massive body in space. Gravity waves are waves that occur in some fluid medium when disturbed from a state of equilibrium, … Continue reading What the Heck are Gravitational Waves?
We've all heard the stories about stuff on Earth you can see from space. What does that mean anyway? From where in space? Earth, after all, is located in space. Is it where the atmosphere ends? And from that point, what can you see on the surface? There are a variety of altitudes we use … Continue reading Where is Outer Space and What Can You See From There?
Whether or not we consider Pluto a planet, it orbits the sun just like Earth and everything else we call a planet. Right? Yes and no. While the sun lies roughly at the center of the solar system, there's nothing in physics that sets it apart from any other celestial body in this system. Let's … Continue reading So We Really Don’t Orbit the Sun
I want you to take a moment to leave your computer (or mobile device) screen and go outside. Stand under the sun, away from any trees, and hold your hand out. Congratulations! Billions of neutrinos have traveled through your hand, directly from the sun. You didn't have to put your hand out, stand out in … Continue reading Don’t Fear the Neutrino!
If you've taken the time to check out this article, you probably have also heard some of the hype regarding NASA's experimental spacecraft engines. The granddaddy of them all was a supposed "warp drive" based on a theoretical constructed called the Alcubierre drive. If you're a Star Trek fan, then you probably got goose bumps … Continue reading Is NASA Building a Warp Drive?
If you're anything like me, you've imagined yourself piloting the Millennium Falcon through an asteroid field the way Han Solo did in Star Wars. The density of the asteroid field is high; the giant boulders are close together and collide frequently. It takes a skilled and heroic pilot to make the journey across. The idea … Continue reading Is an Asteroid Coming to Kill Us?
