Which animal is the best runner? Most of you must have already guessed that it is the cheetah, but is it the best runner? To find out, let us understand the top speed and stamina required by the land animal. The cheetah is the fastest animal on land and has a top speed of 130 kilometres per hour but it can only run about 460 meters. In fact an average human can run 9000 meters or 9 kilometres. So, if you’re looking for an animal with great speed and stamina it’s the pronghorn antelope, the 2nd fastest animal on land. It has a top speed of 98 kilometres per hour and can run 32186.9 meters or an estimated 32 kilometres. It can achieve this with special heat glands on its face. Which animal is the best swimmer? Well, unlike the questions, Which animal is the best runner and Which animal is the best flyer, this one is easy. It is the sailfish which has a top speed of can go up to 110 kilometres per hour. The sailfish is a member of the billfish. The billfish include the sailfish, the sword...

Big bang and solar system formation It all started 14 billion years ago the universe was super small. Previously, the universe was a singularity. Which is a point that is infinitely small and infinitely dense. 13.7 billion years ago It had exploded and this was called the big bang. Several things happened. The 4 forces of the universe formed. This created protons and electrons along with positrons and anti-protons (anti-matter). They collided to create mini-explosions everywhere. Eventually, after millions of protons and electrons of matter and anti-matter, matter was too much and stayed. This all happened in 1 second. Also, for 380,000 years electrons and protons never met. They never met because the heat of the universe stopped them from interacting. This was the first time an electron and a proton crashed. This formed the first element: hydrogen (which has 1 electron and 1 proton). After a few billion years that element formed gas clouds. One such gas cloud (called the solar nebula)...
