I Fucking Love Jock Villagers In Animal Crossing They're Just Like, "what Is UP Bro Your Triceps Are

Hey. Reach out your hand I got something for ya.

it’s a known fact that nasa = gay. have you ever seen a straight person wearing a nasa tee? no, ofc not. we’ve got the moon. now mars. next thing you know it’s the entire solar system. boom the milky way. the gays are spreading, in this essay i will

So an ambulance just drove by my house and it was blasting never gonna give you up and the closer it got, the more distorted the song became. What kind of alternate reality am I living in…

dude seeing these Mega high quality images of the surface of mars that we now have has me fucked up. Like. Mars is a place. mars is a real actual place where one could hypothetically stand. It is a physical place in the universe. ITS JUST OUT THERE LOOKING LIKE UH IDK A REGULAR OLD DESERT WITH LOTS OF ROCKS BUT ITS A WHOLE OTHER PLANET? 

We say Goodbye to 2017. We say Goodbye to a good year. Here’s our Top 10. 

Thanks for reading everybody. It’s a pleasure to make these silly comics and to receive all the crazy love. See you next year!  

Black holes

A black hole is a region of spacetime exhibiting such strong gravitational effects that nothing—not even particles and electromagnetic radiation such as light—can escape from inside it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole. The boundary of the region from which no escape is possible is called the event horizon. Although the event horizon has an enormous effect on the fate and circumstances of an object crossing it, no locally detectable features appear to be observed. In many ways a black hole acts like an ideal black body, as it reflects no light.  

The idea of a body so massive that even light could not escape was briefly proposed by astronomical pioneer and English clergyman John Michell in a letter published in November 1784. Michell’s simplistic calculations assumed that such a body might have the same density as the Sun, and concluded that such a body would form when a star’s diameter exceeds the Sun’s by a factor of 500, and the surface escape velocity exceeds the usual speed of light.

At the center of a black hole, as described by general relativity, lies a gravitational singularity, a region where the spacetime curvature becomes infinite. For a non-rotating black hole, this region takes the shape of a single point and for a rotating black hole, it is smeared out to form a ring singularity that lies in the plane of rotation. In both cases, the singular region has zero volume. It can also be shown that the singular region contains all the mass of the black hole solution. The singular region can thus be thought of as having infinite density. 

How Do Black Holes Form?

Scientists think the smallest black holes formed when the universe began.

Stellar black holes are made when the center of a very big star falls in upon itself, or collapses. When this happens, it causes a supernova. A supernova is an exploding star that blasts part of the star into space.

Scientists think supermassive black holes were made at the same time as the galaxy they are in.

Supermassive black holes, which can have a mass equivalent to billions of suns, likely exist in the centers of most galaxies, including our own galaxy, the Milky Way. We don’t know exactly how supermassive black holes form, but it’s likely that they’re a byproduct of galaxy formation. Because of their location in the centers of galaxies, close to many tightly packed stars and gas clouds, supermassive black holes continue to grow on a steady diet of matter.

If Black Holes Are “Black,” How Do Scientists Know They Are There?

A black hole can not be seen because strong gravity pulls all of the light into the middle of the black hole. But scientists can see how the strong gravity affects the stars and gas around the black hole. 

Scientists can study stars to find out if they are flying around, or orbiting, a black hole.

When a black hole and a star are close together, high-energy light is made. This kind of light can not be seen with human eyes. Scientists use satellites and telescopes in space to see the high-energy light.

On 11 February 2016, the LIGO collaboration announced the first observation of gravitational waves; because these waves were generated from a black hole merger it was the first ever direct detection of a binary black hole merger. On 15 June 2016, a second detection of a gravitational wave event from colliding black holes was announced. 

Simulation of gravitational lensing by a black hole, which distorts the image of a galaxy in the background 

Animated simulation of gravitational lensing caused by a black hole going past a background galaxy. A secondary image of the galaxy can be seen within the black hole Einstein ring on the opposite direction of that of the galaxy. The secondary image grows (remaining within the Einstein ring) as the primary image approaches the black hole. The surface brightness of the two images remains constant, but their angular size varies, hence producing an amplification of the galaxy luminosity as seen from a distant observer. The maximum amplification occurs when the background galaxy (or in the present case a bright part of it) is exactly behind the black hole.

Could a Black Hole Destroy Earth?

Black holes do not go around in space eating stars, moons and planets. Earth will not fall into a black hole because no black hole is close enough to the solar system for Earth to do that.

Even if a black hole the same mass as the sun were to take the place of the sun, Earth still would not fall in. The black hole would have the same gravity as the sun. Earth and the other planets would orbit the black hole as they orbit the sun now.

The sun will never turn into a black hole. The sun is not a big enough star to make a black hole.

Today is a remarkably profound day in American history, and an even more profound day for humankind.

After years of delays for perfection, SpaceX has successfully launched its FALCON HEAVY rocket, defying the force of gravity, and make its way onto an elliptical heliocentric orbit near Mars. The payload - Elon Musk’s personal midnight cherry red Tesla Roaster, with a dummy named Starman wearing a SpaceX space suit in the driver seat, playing David Bowie’s Space Oddity on repeat, with “Don’t Panic” (Hitchhiker’s Guide To The Galaxy reference) on the screen. This car is set to orbit for the next billion years, or upon destruction. This car has potential to outlive the Earth.

Now, this launch is utterly profound for too many reasons to list (although I’ll try). First and foremost, this finally begin the tangible reality of the ultimate goal of SpaceX - to make humans an interplanetary species. This rocket has the capability to take humans, to and from Mars. And although this will not be the rocket that does it, it has shown it is possible. Today marked the first move for humans going to Mars from a paper idea, to a pragmatic reality.

Furthermore, SpaceX, as a private company has entirely reconfigured space travel by its stupid-simple innovations. To simply, basically, space travel is expensive. Really expensive. Part of this reason was because the first stage and second stage (the most expensive parts of the rocket) would crash down into the ocean after use, rendering it useless. Essentially, this is like getting a new McLaren F1, to drive from NY to Boston, just to throw it away once finished. Obviously, this is extremely economicaly inefficient. However, no agency has actively sought to fix this problem because it was viewed as incorrectable, and because space travel has been dominanted by government agencies.. and as we know, government agencies spend frivolously and often don’t care about price.

What SpaceX has done to correct this giant problem was devise away to have the first stage booster descend back to Earth, and slowly and surely drop on a pad either on land or on a tracked floating device in the ocean (to understand how preposterous this is, try to imagine a 25 story building, falling from space, landing on a autonomous pad in the ocean that’s the size of a football field). This was LONG declared as impossible by numerous scientists and physicists, but despite the odds, a private company has not only managed to do this, but do successfully over 15 straight times. This was viewed IMPOSSIBLE in early 2016. Today, we viewed two boosters simultaneously land with the Falcon Heavy launch - AND these two boosters that were used today were previously recovered ones from past Falcon 9 missions. For record of how much cheaper this has made space travel:

Nasa Space Shuttle Launch - cost around 500 million

SpaceX Falcon 9 launch - cost around 50 million

The other reason why SpaceX has managed to make space travel 450 MILLION dollars cheaper is because of how it make its products. EVERYTHING IN SPACEX (and Tesla, btw) IS MADE IN HOUSE. Everything. Everything made on American soil, by American workers, IN FUCKING HOUSE. It is of course immensely difficult to build a fucking rocket from scratch, but SpaceX has perfected it. Instead of buying a computer from this company (who has to mark up to get a profit) who gets their mother board from this company (who has to mark up to get a profit) who gets their chips from this company (who has to mark up to get a profit) - everything is made IN house. As a quick example on how expensive mark up prices become after running through a few companies - A mass amount RADIOS for Tesla through a company would normally cost around 100,000 dollars, but when Musk’s team learned how to perfect it for cheaper, they brought thay price way down to 5, 000 dollars. This in house economic principle has made space travel FAR more plausible for the public then we ever could have imagined. And as SpaceX gets better, prices will continue to plummet.

After many stagnant years, there has been little to any innovation in the improvment of space travel. Since 1969 and the Apollo mission to the moon, there has been little for the public to cheer on, with regards to NASA and American space travel. However, SpaceX has given our generation a voice. It has given our generation a profound meaning. Many of us will witness the day when humans set foot on Mars, and many will witness the moment when humans first begin to colonize the red planet. Our generation has something unbelievable to stand behind - not only as a very proud nation, but as a world united. Curiosity and knowledge connects people all over the world, and traveling the cosmos and becoming an interplanetary species will have a uniting effect far greater than any of us can imagine. We are living in a very special time. Days like today will always be remember in American history, demonstrating the amazing capability of determined humans, when curiosity strikes. Lastly, it is also a reminder that many creations today were once rendered as impossible - having a Tesla flying throughout the solar system launched by the most powerful rocket currently in the world is a giant middle finger for all the thousands who have sworn that both Tesla and SpaceX would never ever be able to make it. Both began as startups with a small team of determined workers, both became near bankrupt in 2009, and today, we witness a cherry red Tesla heading into space playing David Bowie to visit the red planet. If that’s not motivating, I don’t know what is.
