Trying to figure out exactly what the Big Bang was, what caused it, and what might have come before it, is one of the greatest and most fundamental questions in understanding our universe. One new theory, that may sound crazy, but is mathematically sound and possibly testable, is that what we perceive as a “big bang” was the collapse of a four dimensional star into a black hole, and that our three dimensional universe is merely that four dimensional star being smashed into three dimensions, exactly like how in our universe, three dimensional objects become two dimensional when they reach the event horizon of a black hole.
The simple principle that illustrates how we may have been misinterpreting quantum mechanics this whole time
At the quantum level, things have been described as “super weird” and “doesn’t make any damn sense based on what we know”, what with quantum particles appearing and disappearing, moving across time and space instantaneously, spontaneously come into being and annihilate, seeming to exist in multiple places at once, etc etc. But one interesting experiment has shown that perhaps the quantum world does operate with some kind of mechanics we already understand, even by certain principles of classical physics.
The experiments involve an oil droplet that bounces along the surface of a liquid. The droplet gently sloshes the liquid with every bounce. At the same time, ripples from past bounces affect its course. The droplet’s interaction with its own ripples, which form what’s known as a pilot wave, causes it to exhibit behaviors previously thought to be peculiar to elementary particles — including behaviors seen as evidence that these particles are spread through space like waves, without any specific location, until they are measured.
Just because NASA’s budget isn’t nearly what it should be, it doesn’t mean they can’t dream big about the future. The above rendering is a beautiful look at what NASA thinks a warp drive ship of the future would look like. There’s the ship itself, and on the outside, you’ll notice the two enormous rings that would theoretically create the warp bubble.
Scientists have long theorized that you can create matter from light by colliding photons, but proving that theory has been a different story — you need the right high-energy particles to even think of trying. However, it looks like that once-impossible dream is close to becoming reality. Researchers at Imperial College London have discovered a technique that should produce electrons and positrons by colliding two sets of super-energetic photons.
Quantum teleportation via quantum entanglement has been something that a whole lot of the world’s brightest minds have been putting a lot of time and energy into, but so far, manipulating the weird rules of the quantum world to our own uses has been mostly elusive. But scientists at the Kavli Institute of Nanoscience Delft say they’ve managed to reliably teleport quantum info stored in one bit of diamond to another sitting three meters away (roughly 10 feet). Now, they want to go much farther.
Among the many, many things that made Bruce Lee the most badass mofo in modern history, his signature one-inch punch was one of the most well known and consistently impressive. From just one inch away, he could deliver a blow so powerful it could literally knock a grown man off his feet. So how exactly does a martial artist like that deliver such a jolt of power in such a short distance? It all has to do with the beauty of physics and biomechanics and Bruce Lee’s uncanny muscle control.
For centuries, how exactly ancient Egyptians moved massive stone blocks weighing over 2 tons and massive statues across the desert with fairly primitive technology. As it turns out, the Egyptians didn’t make a secret of their secret— it’s right up there in the painting. See it?
They moved stones on flat sleds with an upturned front edge, but if you try to drag a heavy sled across sand, the sand will build up in front, Now see the guy standing at the front of the sled? He’s pouring water on the sand. Because as it turns out, just the right amount of water increases the stiffness of the sand and reduces the force needed to pull the thing by half. Or you can just say it was aliens.
