1)ACTUAL SPEED OF LIGHT: In the vacuum of the universe, light travels at a speed of 299,792,458 meters (983,571,056 feet) per second. 186,282 miles per second - also called c, or the speed of light - is a universal constant in equations. The majority of modern physics is based on Albert Einstein's theory of special relativity, which states that nothing can travel faster than light. As matter approaches the speed of light, the mass of that matter becomes infinite. As a result, the speed of light is the speed limit of the universe.  The moon is about 1 light-second away from our eyes since light travels from the moon to our eyes in about 1 second. Considering that sunlight takes 8 minutes to reach our eyes, the sun is approximately 8 light-minutes away. Our nearest star system, Alpha Centauri, is 4.3 light-years away. Light from Alpha Centauri takes 4.3 years to reach us, so Alpha Centauri is 4.3 light-years away. One light-year is a distance that can be covered by light in an e...

​The Sahara Desert is one of the most exposed places on Earth to the sun’s rays. So, the idea is that if we could gather all that energy, we could power the world. In reality, we would harvest so much more energy than we could ever possibly need. According to Forbes, solar panels covering a surface of around 335km2 would actually be enough to power the world, this would cover just 1.2% of the Sahara Desert. Outside of electricity generation, this could have several consequences. First, the light colour of the Saharan sand serves the purpose of reflecting the sun’s light and heat back into the air. By covering this, we would be ensuring that more sunlight is absorbed, thus prompting a rise in ground temperature. Warmer air then rises to higher altitudes and condenses as clouds that will then fall as rain, completely transforming the desert as we know it. The planet works based on a series of well-balanced systems, and this could completely upset the apple cart. The Amazon Rainforest, fo...

 ​​How is Math used in Video Game designing and programming? Math is an absolute fundamental foundation to successful game development and game design. Math is everything when it comes to games. From having the ability to calculate the trajectory of an Angry Bird flying through the sky, to ensuring that a character can jump and come back down to the ground without the help of mathematics, games simply wouldn't work. A character wouldn't be able to walk up a slope, slide down a slide, fire a bullet from a gun, or even jump without the help of the mathematics. The most basic of games use some form of math to the most complex of games. Math is essential to the production of games. It is the flour to the cake that game developers are trying to bake. Without it, the cake wouldn't rise. Math is used in every aspect of game development, including art. Maya is a math based program that plots out the vertices and normals in mathematical form while the artist just uses a tool th...

       When you look up into the sky on a clear night, you’ll see stars littered throughout the darkness. It may seem like a random pattern. But some people used those patterns to tell stories—and the stars still have uses for scientists today. A constellation is a group of stars that create a recognizable pattern in the sky.   There are 88 officially recognized constellations, some of which are named after mythological creatures and might sound familiar if you’ve ever looked up your horoscope. Some of them are named after heroes like Hercules and Orion. Other star patterns are named after animals, like Ursa Major or the big bear. The stars acted as a way to preserve stories, like the legend of Perseus rescuing princess Andromeda from a sea monster named Cetus. Certain parts of the sky let you see the whole story from one constellation to the next. These constellations are used for more than just remembering stories. Explorers used constellations to navig...

 How are exoplanets detected? Exoplanets are detected in many ways but the two most common are the transit passing method & the ‘wobble’ method.  The transit passing method is when you observe a specific star over a period of days to weeks. Over that period, a planet that may be orbiting that star could come into view between the telescope and the star, thus blocking out some of its starlight from our view. The ‘wobble’ method is measuring the point for which a star orbits. If a star has planets orbiting them, the star will orbit a point that is outside its center of mass called the barycenter and not its own center  of mass. The barycenter is determined by the mass of two (or more) objects and the distance between them. For all of the planets in our own solar system, the barycenter is still inside the Sun, all except for Jupiter-Sun system. When we’re observing a star and notice a pattern of red shifts to blue shifts on the electromagnetic spectrum, we can deduce tha...

  ​​ What is a White hole? A white hole is a bizarre cosmic object which is intensely bright, and from which matter gushes rather than disappears. In other words, it’s the exact opposite of a black hole. But unlike black holes, there’s no consensus about whether white holes exist, or how they’d be formed. They are predicted by Einstein’s theory of gravity, and are most often mentioned in the context of ‘wormholes’, in which a black hole acts as the entry point to a tunnel through space and time, ending in a white hole somewhere else in the Universe. But this is deeply controversial, because Einstein’s theory predicts the existence of a so-called singularity at the centre of black holes – a state of infinite gravity which would prevent anything from passing through to the white hole on the other side. However, some theorists think that a combination of Einstein’s theory and quantum theory points to a new way of thinking about white holes. Instead of being the ‘exit’ from a worm...
