Wait, are you telling me humans living in different corners of the world all somehow managed to figure out how to stack blocks into a large pile? Without the help of aliens? Before Pinterest? Bullshit.

Coldest white dwarf ever discovered is basically an Earth sized diamond

ICE COLD

Astronomers have detected an ancient stellar remnant that’s 10 times fainter than the dimmest white dwarf ever discovered. Fortuitously orbited by a pulsar, this cold and collapsed star consists of crystallized carbon — essentially making it an Earth-sized diamond in space. Indeed, this white dwarf would have never been discovered if it hadn’t been for the pulsar that spins around it.

Caution: Watching this video will probably make you temporarily hallucinate 

This video may cause temporary hallucinogenic effects. But please do not be afraid, these effects usually last a few seconds. Read aloud every letter in the screen center. Do not make any mistake. In the end “LOOK AWAY NOW” when it says so in red letters. If you feel dizzy don’t worry it will soon go away or just stop watching the video.

If the Moon were only 1 pixel…a humbling map of the Solar System

Be prepared for a whole hell of a lot of scrolling. This map is pretty awesome in the sense that it really puts perspective on just how much distance there is between us and basically everything in just our small corner of the Milky Way.

Here’s the map

Tibetans got their amazing high altitude genes from long extinct Denisovans

Genetic research has already discovered that early humans in Europe mingled genes (bumped uglies) with Neanderthals, now it looks like Tibetans’ unique tolerance for extremely high altitudes can directly be traced to genes from another long extinct hominid race, the Denisovans. Denisovans were one of many ancient human species that lived at the same time as early Homo sapiens. The genes that Tibetans inherited allow for a better use of blood oxygen at higher altitudes that would make lesser mortals’ blood thicken above 15,000 feet to deadly levels.

The truth of “the American Empire”. Yes, we’re kind of an empire, though under a different name

We don’t have an emperor, and we don’t have a traditional old style empire, but this video explains why the term still applies.

Why You Are Still Alive - The Immune System Explained

Every second of your life you are under attack. Bacteria, viruses, spores and more living stuff wants to enter your body and use its resources for itself. The immune system is a powerful army of cells that fights like a T-Rex on speed and sacrifices itself for your survival. Without it you would die in no time. This sounds simple but the reality is complex, beautiful and just awesome.

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.
