Unless you're an astronaut you probably don't spend a lot of time thinking about gravity . We all take gravity for granted and it would be hard not to aside from a tiny sliver of the world's population. Most humans don't know a life without gravity from the universe to our solar system to each planet, all the way down to our own bodies gravity holds everything together like a chain. But since we tend to see gravity as a given it's hard to imagine just how helpless we would be without it until it's actually gone. First of all, let's see what gravity really is? Gravity is an attractive force between any two masses the greater the mass the greater the gravity the greater the gravity the stronger the pull. Gravity is the reason why Earth rotates around the sun. Why we experience high and low tide and why we can walk on this planet without floating away. Not only that though gravity secures our atmosphere holding in the air we need to breathe. In fact, there ...
Black holes are the most popular and most curious one thing in our universe. In universe some incidents can understand to our brain, and they can explain in science. To explain that cases, experts or scientist may use some laws, arguments and etc... In that explanation they may justice for some cases. So, in this blog today we talk about Black Holes. In 1961 German physicist and astronomer Karl Schwarzschild gave the first explanation about Black holes. In that explanation he used Albert Einstein's relativity theory and by calculating and showed that any object given the right amount of thrust can become a black hole. Black holes are not simply can learn object., let's try to understand this amazing topic in simple way. A black hole is simply an object where a large mass is squeezed into a small area. Actually, this can be described as a collection of several very small masses rather than a cavity. According to scientist the real reason for extreme gravity...
Yes, my astronomers there's been a rise in global temperature in recent times and depletion of the ozone layer is one of the factors behind it. So, in today's blog let us go beyond the atmosphere and explode this invisible protective shield. That surrounds the earth and tackles a globally important question, what is the ozone layer? and what's causing a hole in it? Did you know the word ozone means smelly in Greek because the gas has a strong order. So, let's talk about what is ozone layer. Have you ever wondered why do you apply sunscreen before stepping out into the sun. Well, that's because of harmful radiation known as uv rays or ultraviolet rays emitting from the sun. But despite their fascinating name too much exposure ...
