    "Four billion years from now, our galaxy, the Milky Way, will collide with our large spiraled neighbor, Andromeda.

    The galaxies as we know them will not survive.

    In fact, our solar system is going to outlive our galaxy. At that point, the sun will not yet be a red giant star – but it will have grown bright enough to roast Earth’s surface. Any life forms still there, though, will be treated to some pretty spectacular cosmic choreography.

    Currently, Andromeda and the Milky Way are about 2.5 million light-years apart. Fueled by gravity, the two galaxies are hurtling toward one another at 402,000 kilometers per hour. But even at that speed, they won’t meet for another four billion years. Then, the two galaxies will collide head-on and fly through one another, leaving gassy, starry tendrils in their wakes. For eons, the pair will continue to come together and fly apart, scrambling stars and redrawing constellations until eventually, after a billion or so years have passed, the two galaxies merge. "

    So, apparently computers are one step closer to conquering the planet.

    Turing Test breakthrough as super-computer becomes first to convince us it's human

    So, the Turing test (which I know nothing about, so I guess I will be googling after writing this) is now beaten. Computer programs made one more step towards creation of the AI. And we all know how that ends - world war, humans are nuked, and terminators rule the Earth.
    But anyhow, I do wonder. Could it be just a single a coincidence? Or maybe programs really becoming that advance. Or maybe the test becoming obsolete...

    Yep, we need some new tests to detect those damn cyborgs!

    Cutting beer bottle with cotton string/yarn

    http://www.wikihow.com/images/4/44/Cut-a-Glass-Bottle-Step-13.jpg Wrap your yarn. If you don’t have yarn available, you can use any thick cotton string. At the location of where you would like the bottle to break, wrap a piece of yarn around the bottle 3-5 times. Tie the ends together and cut off any excess string. http://www.wikihow.com/images/1/10/Cut-a-Glass-Bottle-Step-14.jpg Soak the yarn in acetone. Slide the yarn off the end of the bottle, and place it in a small dish or lid. Pour a bit of nail polish remover or straight-up acetone over the yarn until it is completely soaked. You can pour the excess acetone back into the bottle afterwards. http://www.wikihow.com/images/c/c7/Cut-a-Glass-Bottle-Step-15.jpg Wrap the bottle again. Take the yarn and replace it back on the bottle in the exact location you want it to break. Try to make sure that the loops of yarn are placed close together and are tight so that you get a level, clean break. http://www.wikihow.com/images/b/b8/Cut-a-Glass-Bottle-Step-16.jpg Light the yarn on fire. Use a match or a lighter to catch the yarn (on the bottle) on fire. Rotate the bottle slowly so that the yarn burns at a consistent speed around the entire bottle. http://www.wikihow.com/images/a/a3/Cut-a-Glass-Bottle-Step-17.jpg Dunk the bottle in cold water. Have your sink or a pot filled with cold water - you can add ice as well if you would like. Wait until the fire on the yarn has burnt out, and then stick the end of the bottle with the yarn directly into the water. The bottle should break cleanly off where the yarn was wrapped around it. http://www.wikihow.com/images/3/38/Cut-a-Glass-Bottle-Step-18.jpg (Warning, do not inhale glass smoke, duh. Maybe do this step with the glass underwater) Sand the edges. Use a rough sandpaper to smooth down the jagged edges on the broken section of the bottle. When you have removed any sharp corners, switch to a fine grit sandpaper to give the bottle a smooth, soft finish. You’re done!

    I recommend subscribing to the Kurzgesagt channel. Even if you know what it talks about already, they're cute little videos about things.

    Here's a nice video about the body and it's defences:


    Also a different channel that I really recommend for science-lovers is Minute-Earth

    Minute-Earth and Minute Physics are my favorite channels after Vsauce to just learn interesting stuff - i feel like a nerd heh..

    Vantablack is the new black

    black is the new black

    What you see above is a new material called Vantablack. It is so dark that you aren't even seeing it. You are seeing the stuff around it.

    Your Eye's Blind Spot

    Close your right eye and look at the big black circle with your left eye. Keep the cross in your peripherals. Now slowly start moving your head toward the screen, with your left eye still focused on the big black circle. The cross should disappear for a second, and if you position your head right it will completely disappear as long as your head is in that position.

    Why does this happen? It's because we all have blind spots in our eyes. We don't notice the blind spot when both our eyes are open. Thats because our eyes do a good job hiding them and covering each others blind spots.
