What will happen if Moon fell on Earth ?

Moon is currently 384,400 km away from us. Its diameter is 3,474 km & the mass is 7.3 × 10^22 kg.

So what will happen if Moon fell on Earth?

Imagine moon just stopped orbiting & started moving towards Earth. On hitting earth it will release 10^20 Gigajoules of energy, which is 4 billion times the total energy of all nuclear weapons in the world right now.

The impact will melt the Earth's crust where it hits & the average surface temperature will increase from 15˚C to 735˚C. As a result, Oceans & IceCaps will be vaporized within a few minutes & lava will cover the entire earth's surface.

If the moon hits earth then probably our planet would never be able to sustain life again.

But the fact is you don't need to worry about it because the moon is actually going away from earth at a rate of 3.8 centimeters per year. In about 50 billion years, the Moon will stop moving away from us and settle into a nice and stable orbit.

What If a needle or a grain of sand hits the earth at the speed of light?

We are used to anticipating danger from outer space . A huge almost unknown space hostile to humans and no wonder colossal explosions take place asteroids and comets travel at tremendous speed . There are black holes and all this can potentially cause the death of the earth but what about something small for example an ordinary sewing needle what if one finds itself in space accelerates to the speed of light and then crashes into our planet .   Any object consisting of matter can't move at the speed of light or faster so scientists from NASA are unlikely to ever consider such a disaster well I will do it for them today you'll know how dangerous such small things can be if they are properly accelerated and at the same time, you'll learn about another strange scenario of the end of the world . Our planet is constantly bombarded by various cosmic bodies we don't even notice most of them they just burn up in the atmosphere .     Sometimes celestial b

What made Albert Einstein a Genius?

Image
In short,  Albert Einstein's brain was different from ours ! Without the contributions of Albert Einstein, our world would be a totally different place. Some of his biggest scientific contributions include, The Brownian motion  which helped us understand the liquids better, The photoelectric effect  which gave us the solar panels, The world's most famous equation  E=mc^2 on which the nuclear bombs are based,& the  Theory of relativity , which helped us understand the deepest mysteries of the Universe. So, what made him so smart to do those wonder & change the world forever?  Here's what made Albert Einstein a Genius? When scientists examined  Einstein's brain deeply , they find out that Einstein's exterior brain was missing a particular wrinkle called a  parietal operculum . So, the size of his parietal lobe was increased by 20%. The parietal lobe is the are of the brain responsible for one's mathematical skills & mental images.

Would we ever be able to build a Time Machine?

Image
Well, Time Travel is just a  technical problem  now There are several ways we can travel in time (future), two of them are, 1. Orbiting a Black Hole -  Time slows down as we reach an object with high gravitational potential. So, we could orbit closer to a Black Hole, then for us time will run slower compared to the people on Earth. 2. High Velocity -  As per relativity, the faster we move slower the time gets. So, if we could build a spaceship that can reach speed closer to light, then we would be able to travel in time. As I said, right now time travel is a technical problem & our today's technology isn't advanced enough to build such spacecraft. However, some people are trying make this happen, for example,  Harold White  at NASA is trying to build an  Alcubierre Warp Drive .

How do Ships float in water ?

Image
According to the  Archimedes principle , " an object in a fluid experiences an upward force equal to the weight of the fluid displaced by it. " The same principle goes for the floating ships. The reason ships float is that they displace a lot of water, if a ship could not push enough water out of the way, it would probably sink. The displaced water wants to return in its original form, where the ship is now, & keeps pushing it upwards. As a result, we get a smoothly floating ship. The force which pushes the ship up is called the buoyancy force. Designers keep it in mind that the ship will displace the total amount of water equal to its weight, way before the water gets in.
