Although it seems that modern technology is all about making everything smaller, when it comes to unlocking the secrets of the universe, science is all about going big. Really big. Right at this moment, scientists and engineers are in the process of building -- or using -- instruments that look like the engine for a Star Destroyer.
5The Death-Star-Sized Laser at the National Ignition Facility
The competition to create the world's biggest laser sounds in every way like a duel between competing supervillains, with names like "The Omega Laser" and "The Z Machine." But don't worry. After all, would a supervillain build something that looks like this?
This thing has three giant shark tanks and no bathrooms.
Yeah, that's the Department of Energy's National Ignition Facility in Livermore, California. It's three football fields' worth of deadly laser force, and the components are all terrifyingly huge. Here, let's play a game of "find the tiny workers among these pictures of giant laser parts."
It's like Where's Waldo? for the Ivy League set.
So what does all of that stuff do? Well, in 5 millionths of a second, the NIF can charge and deliver 192 beams of laser love capable of generating temperatures of 100 million degrees Celsius, and pressures greater than 100 billion times that of the Earth's atmosphere.
What could possibly be the purpose of such a thing, short of carving your name onto the face of the moon? Actually, scientists are trying to create nuclear fusion, the Holy Grail of energy technology. It's literally the energy source that powers the sun, and to make it happen, they're going to unload the full force of laser fury into a packet of hydrogen the size of the full stop at the end of this sentence.
In other words, the NIF is here to bust a nut.
As an added bonus, by recreating the extreme conditions of the core of the sun, the NIF can help us understand what kind of crazy crap happens inside stars and supernovas, which is convenient because we can't really test either of those things in the field.
It's at this point that scientists turn to steampunk.
4IceCube -- the 1.5-Mile-Tall Polar Neutrino Observatory
There is a telescope more than 7,000 feet tall, made up of over 5,000 sensors dangling from a gigantic array of cables. It exists, right now, and we can't show you a picture of it.
Why? Well, the IceCube Neutrino Observatory has been designed to detect a very specific kind of light. To do this, it needs to be dark. And we mean dark, as in, "so dark that they had to bury the instrument more than a mile and a half underneath Antarctica" dark. It's so far down that scientists actually measure the distance in skyscrapers.
That's 394 T-rexes in Cracked-speak.
What IceCube is searching for is actually one of the smallest objects in the universe -- the neutrino. A neutrino is so tiny that it can pass through a block of lead one light-year thick as though it were empty space. That means that even though 65 billion of them are passing through each square centimeter of Earth every second, the vast majority of them don't even notice they just flew through a planet.
Scientists first tried using the densest material on Earth to capture a neutrino, but they didn't have David Stern's brain handy.
Every so often, though, a neutrino will collide with an atom. This is kind of like hitting a mosquito with a bullet, but given enough bullets and enough time, it happens eventually. That's where IceCube comes in. When a neutrino does hit something, it makes a tiny spark of light. Five skyscrapers deep under the Antarctic ice is the only place in the world dark enough and yet clear enough to see these collisions occurring.
That's if the Morlocks don't get you first.
Why do scientists care so much? Well, by studying neutrinos, apparently we can discover all sorts of freaky new crap in the universe, from dark matter, to supernovas, to extra dimensions. Or, just maybe, The Thing.
