Well when you read through the images below... you'll either think you're totally insignificant, or it'll reaffirm your belief that our existence is really that special.

The short answer is that light coming out of your torch instantly reaches the speed of light. Light can only ever travel at the speed of light — 300,000,000 metres per second in a vacuum, and a bit slower in air because it bumps into molecules.
So why is light only allowed to travel at that one speed? "There are two ways to answer that question" says David Jamieson, professor of physics at the University of Melbourne. "The speed of light is the speed of light in order to guarantee the Lorentz transforms, but that's too deep". Thankfully he has a better way — with an analogy to waves in string. "Imagine you've got a tight string and you pluck it and a wave goes shooting down the string.
But there's a big difference between light waves and these waves. Two constants make another constant Professor David Jamieson spoke with Bernie Hobbs. Stars.chromeexperiments. Bangkok Globe | 26 Pictures Will Make You Re-Evaluate Your Entire Existence. The universe, man… THE UNIVERSE. 1.

Einstein's Theory of Relativity & why E=mc², In One Simple Animation! 10 Strange Things About The Universe. Space The universe can be a very strange place. While groundbreaking ideas such as quantum theory, relativity and even the Earth going around the Sun might be commonly accepted now, science still continues to show that the universe contains things you might find it difficult to believe, and even more difficult to get your head around. Theoretically, the lowest temperature that can be achieved is absolute zero, exactly ?
273.15°C, where the motion of all particles stops completely. However, you can never actually cool something to this temperature because, in quantum mechanics, every particle has a minimum energy, called “zero-point energy,” which you cannot get below. Remarkably, this minimum energy doesn’t just apply to particles, but to any vacuum, whose energy is called “vacuum energy.” One prediction of Einstein’s theory of general relativity is that when a large object moves, it drags the space-time around it, causing nearby objects to be pulled along as well.

Animated Infographics of how things work. NVIDIA GPU & Physically Based Lighting Show “Moon Landing Was Real” As NVIDIA launched its new Geforce GTX 970 and GeForce GTX 980 graphics processors (GPUs), its “Demo team” has taken a stab at solving one of the big controversial stories of the century: was the lunar landing real or fake? There is ample literature on the subject and there is no shortage of reasons why some people think that the lunar landing and mission was shot in a studio.
One of the main arguments of conspiracy theorists was that the lighting seemed wrong in the scene where Buzz Aldrin comes out of the lunar module. It was suggested that there was a light next to the camera, which would mean that it was shot in a studio, since no such equipment was brought to the moon. To shed some context, Physically-based lighting is the notion of measuring how light reacts to different types of materials and use this data for real-time rendering. In the past, the industry has used arbitrary values that were more “art-based” than “physics-based”.

What would you call them? -Me, when a friend asked me why they’re named what they are Ah, black holes. The ultimate shiver-inducer of the cosmos, out-jawing sharks, out-ooking spiders, out-scaring… um, something scary.
But we’re fascinated by ‘em, have no doubt — even if we don’t understand a whole lot about them. But then, that’s why I’m here. Allow me to be your tour guide to infinity. So below I present ten facts about black holes — the third in my series of Ten Things You Don’t Know (the first was on the Milky Way; the second about the Earth). 1) It’s not their mass, it’s their size that makes them so strong.
OK, first, a really quick primer on black holes. The most common way for a black hole to form is in the core of a massive star. As the core collapses, its gravity increases. The region around the black hole itself where the escape velocity equals the speed of light is called the event horizon. So there you go. Hmmm. No! How a Car Engine Works - Animagraffs.

Einstein for Everyone. Einstein for Everyone. Magenta Ain't A Colour. A beam of white light is made up of all the colours in the spectrum. The range extends from red through to violet, with orange, yellow, green and blue in between. But there is one colour that is notable by its absence. You should have seen a green afterimage, but why is this significant? The afterimage always shows the colour that is complementary to the colour of the image. It is a common misconception that red is complementary to green. All the colours in the light spectrum have complements that exist within the spectrum – except green.
The light spectrum consists of a range of wavelengths of electromagnetic radiation. When our eyes see colours, they are actually detecting the different wavelengths of the light hitting the retina. If the eye receives light of more than one wavelength, the colour generated in the brain is formed from the sum of the input responses on the retina.

By Ingrid Longauerová, Epoch Times SOURCE. A Mathematical Proof That The Universe Could Have Formed Spontaneously From Nothing — The Physics arXiv Blog. One of the great theories of modern cosmology is that the universe began in a Big Bang. This is not just an idea but a scientific theory backed up by numerous lines of evidence.
For a start, there is the cosmic microwave background, which is a kind of echo of the big bang; then there is the ongoing expansion of the cosmos, which when imagined backwards, hints at a Big Bang-type origin; and the abundance of the primordial elements, such as helium-4, helium-3, deuterium and so on, can all be calculated using the theory. But that still leaves a huge puzzle. What caused the Big Bang itself? For many years, cosmologists have relied on the idea that the universe formed spontaneously, that the Big Bang was the result of quantum fluctuations in which the Universe came into existence from nothing.
That’s plausible, given what we know about quantum mechanics. Today they get their wish thanks to the work of Dongshan He and buddies at the Wuhan Institute of Physics and Mathematics in China.

The 13 Most Important Numbers in the Universe - James D. Steins Cosmic Numbers. In the 17th century, scientists understood three phases of matter—solids, liquids and gases (the discovery of plasma, the fourth phase of matter, lay centuries in the future).
Back then, solids and liquids were much harder to work with than gases because changes in solids and liquids were difficult to measure with the equipment of the time. So many experimentalists played around with gases to try to deduce fundamental physical laws. Robert Boyle was perhaps the first great experimentalist, and was responsible for what we now consider to be the essence of experimentation: vary one or more parameter, and see how other parameters change in response. It may seem obvious in retrospect, but hindsight, as the physicist Leo Szilard once remarked, is notably more accurate than foresight.
