this-is-proof-that-we-are-completely During your day-to-day life, you can get pretty wrapped up in yourself. You can forget to feed your cats or neglect to call your mother on her birthday. We think our lives are just about us. 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. Well, I suddenly feel very very tiny. How about you? Source: mogul.ws 4192741 When you turn on a torch, does the light instantly reach the speed of light? Or does it accelerate up to that speed very quickly? 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. 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. The physicist James Clerk Maxwell worked out that all light is made of oscillating electric and magnetic fields, coupled together and reinforcing one another. Two constants make another constant
stars.chromeexperiments untitled Bangkok Globe | 26 Pictures Will Make You Re-Evaluate Your Entire Existence The universe, man… THE UNIVERSE. 1. This is the Earth! This is where you live. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. To paraphrase Carl Sagan, everyone and everything you have ever known exists on that little speck. 14. John Brady / Via The sun doesn’t even fit in the image. 15. 16. 17. Our sun probably gets its lunch money stolen. 18. 19. 20. 21. (That’s not a picture of the Milky Way, but you get the idea.) 22. Just THINK about all that could be inside there. 23. 24. Some of the other galaxies are thought to have formed only a few hundred million years AFTER the Big Bang. 25. 26. So if you’re ever feeling upset about your favorite show being canceled or the fact that they play Christmas music way too early — just remember… This is your home. This is what happens when you zoom out from your home to your solar system. And this is what happens when you zoom out farther… And farther… Keep going… Just a little bit farther… Almost there… And here it is. Oh man.
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. One of the properties of a negative-energy vacuum is that light actually travels faster in it than it does in a normal vacuum, something that may one day allow people to travel faster than the speed of light in a kind of negative-energy vacuum bubble. 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. Relativity of Simultaneity This is similar to arranging tiles evenly on a floor.
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. Global illumination means that light that bounces from one surface to another is taken into account.
Ten things you don't know about black holes Well, they’re black, and they’re like bottomless holes. 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. 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. OK, so now you know what one is, and how they form. So there you go. Hmmm.
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.
