Yes, you heard it right. There is something that can take down the entire technological advancements of the mankind in a matter of hours. Any guess..? No it's not the Nuclear war. Let's find out what it is. We all have heard about Nuclear weapons that can destroy the earth by the intense energy released by nuclear fission or fusion. But that's not what we are talking about. We are talking about the naturally occuring fusion reactor in our planet, the sun. The light and heat energy given out by the sun is being used in different ways by the life on earth for it's existence. But there is a limit in everything. Even the energy that we were talking about. You all have heard about the northern light. The colourful waves formed in the sky that gives the night sky a majestic look. But what creates the northern lights? When charged particles from the sun strike atoms in Earth's atmosphere, they cause electrons in the atoms to move to a higher-energy state. Whe...

Mantis Shrimp Mantis Shrimps are one of the cutest but fierce shrimps that can be found in oceans all around the globe. So how does it create a vacuum just with a punch? Let's see. This shrimp is famous for its super punch and its complex eye structure. It's eyes are so good that it can have a full 360 view all the time and it's eyes have more than three times the amount of photo-receptors that a human have. It also has spectacular depth receptors to pin point the exact position of the prey so that it can deliver the perfect punch. Now let's talk about the world's fastest punch this tiny creature can deliver. The punch is so fast that it accelerates at the same speed as that of a 22 caliber bullet. The punch reaches around 45-50 miles per hour in just 3 milliseconds. A saddle shaped part of its exoskeleton which acts similar to a spring boosts the strike speed generated by the muscles.The punch is impossible to see by normal human eyes. We will need high s...

Gravitational wave is a concept that Albert Einstein predicted in 1916. Albert Einstein proposed an idea that gravity comes from the warps and curves in the fabric of space. Gravitational wave is actually like a ripple in the fabric of space. According to Einstein if rapidly orbiting neutron stars or black holes occur on the fabric of space, it creates ripples and these ripples are called as the gravitational waves. As the gravitational waves passes by anything, it stretches and compresses it. If we take the case of earth, the ripples will stretch and compress the earth by less than an atomic diameter. Scientists at Laser Interferometer Gravitational-Wave Observatory discovered the first gravitational wave  on 14 September 2015 and was announced by the LIGO and Virgo collaborations on 11 February 2016. Virgo Interferometer, Italy Since the stretching and compression is of very small size, it is not practical to measure it directly. But scientists have came up w...
