Black holes are the most powerful things in the universe, strong enough to rip whole stars into atom sized pieces Well, this is scary enough. They have an even more powerful and dark property: they might delete the universe itself. Black holes in a nutshell A black hole appears when an extraordinary amount of matter is concentrated in a tiny space. At their center, gravity is almost infinitely strong and whatever gets too close is ripped into its elementary particles.  Not even light can escape black holes, and so we perceive them as spheres of blackness. If you were to fall into a black hole, nothing bad would happen until well after you crossed its outer border: the event horizon. You can imagine this as swimming in a river that ends in an enormous waterfall. As you float along, imperceptibly, the stream gets faster and faster, even if you can't see the waterfall yet. You could swim to safety, until without even noticing it, you cross the point of no return. No ma...

Adobe Photoshop is a raster graphics editor developed and published by Adobe Systems for macOS and Windows. Photoshop was created in 1988 by Thomas and John Knoll. Since then, it has become the de facto industry standard in raster graphics editing, such that the word "photoshop" has become a verb as in "to Photoshop an image," "photoshopping" and "photoshop contest", though Adobe discourages such use. It can edit and compose raster images in multiple layers and supports masks, alpha compositing and several color models including RGB, CMYK, CIELAB, spot color, and duotone. Photoshop has vast support for graphics file formats but also uses its own PSD and PSB file formats which support all the aforementioned features. In addition to raster graphics, it has limited abilities to edit or render text, vector graphics (especially through clipping path), 3D graphics and video. Photoshop's feature set can be expanded by Photoshop plug-ins, progr...

For most of our history, human technology consisted of our brains, fire, and sharp sticks. While fire and sharp sticks became power plants and nuclear weapons, the biggest upgrade has happened to our brains. Since the 1960's, the power of our brain machines has kept growing exponentially, allowing computers to get smaller and more powerful at the same time.  But this process is about to meet its physical limits. Computer parts are approaching the size of an atom.  To understand why this is a problem, we have to clear up some basics.  A computer is made up of very simple components doing very simple things. Representing data, the means of processing it, and control mechanisms. Computer chips contain modules, which contain logic gates, which contain transistors. A transistor is the simplest form of a data processor in computers, basically, a switch that can either block or open the way for information coming through.  This information...

Could we ever create dark matter 85% percent of our universe is a mystery. We don't know what it is made of that is why we call it dark matter. But we know that it is out there because we can observe it's gravitational attraction on galaxies and other celestial objects but scientists theorize that we may actually be able to create it in the most powerful particle collider in the world.  That's the 27-kilometer long Large Hadron Collider, or LHC, in Geneva, Switzerland. In the LHC, 2 proton beams move on opposite directions and are accelerated to near the speed of light. At 4 collision points, the beams cross and protons smash into each other. Protons are made of much smaller components called quarks and gluons. In most ordinary collisions, the two protons pass through each other without any significant outcome. However, in about one in a million collisions, two components hit each other so violently that most of the collision energy is set free. Producing th...
