What does the famous equation E=mc^2 mean?

Whats E=mc^2?
Well today, you are going to find out. A couple of weeks ago, I was watching this video on YouTube about the efficiency of black holes in creating mass into energy. It was all about the equation e=mc^2. I always thought what the equation was very complex but after watching the video, I understood the meaning behind the famous equation.

What it means?

So to keep it simple, E is energy; m is mass, and c is the speed of light squared!
So, Albert Einstein said that energy equals the mass times the speed of light squared! That means that a 5 kg cat is enough to power the country of Norway for 2 years. That much energy from a 5 kg cat is really big. But sadly, we can’t harness 100% of the mass. The best method of getting energy from mass only gets about 0.000007% of the energy from the mass of the object.

To get energy from mass really efficiently, there are 4 ways:
1. Chemical reaction
2. Nuclear reaction
3. Antimatters reaction

Chemical Reactions

Chemical Reactions are like burning. But this is not a practical way of getting energy from mass because it's really bad. Like horribly bad. It only gives out 0.0000000001% of the mass to energy's which is nothing. So, that's not a real way of converting mass into energy.

Nuclear Reaction

This method is a little bit fine but it is still really bad because splitting Uranium 235 into Krypton 92 and Barium 141 and 3 neutrons only generates about 0.08% of its mass into energy! Which is not that bad but really bad at the same time. Fussing Hydrogen into helium like in the sun only generates about 0.07% of its mass to energy.

Anti Matter Reactions

You might think that the first 2 methods are really so this one is too. But, actually, this produces about 100% of mass into energy! This could be a solution for everything! But, there is a catch. First of all, Antimatter is the opposite of matter. Everything is matters. You, me, the world, and even air is matter. But, we have found a way of converting matter into Antimatter. But, it takes a lot of energy to create antimatter itself so that's not a good way either.

Ever wondered what Black Holes are?

Hello Astronomy Enthusiasts, Like I said in my last blog post that I am going to write about what I know about things in astronomy. Today, I am going to tell you about Black Holes, an interesting topic which I love and hope you will too. What are Black Holes? Basically, Black Holes are things that bend space-time extremely and create an area that nothing escapes. Like not even light! The last spot you can be as close to the black hole and not be caught is called the event horizon. It's kind of like a border to the black hole. To understand what it is, you need to know what space-time is. Since objects with gravity bend space-time, black holes bend space-time too. not like the sun or the earth. Million times of our sun. Since the black holes are really huge in gravity the holes bend space-time in an extreme order and it's like putting a bowling ball on a soft, thin sheet of fabric. because of this anything that goes in can't come out because anything is not strong enou...

The Mission that put a Man on the Moon - Apollo Mission

Hi Astronomy Enthuists, First of all, I want to start out by wishing all of you a very happy and prosperous New Year. In today's blog post, I am going to be exploring the famous mission that put a man on the moon which is, of course, the Apollo Mission. I am going to make this post a little different in that I'm going to explain to you guys the Apollo Mission in-depth, separating the different aspects into bite-sized chunks, making all the info much easier to understand.  The Apollo Space Mission's Logo Before we get into the actual Mission, let's talk about the Spacecraft which took the 3 astronauts to the moon and the components of the spacecraft a little. Saturn V The Saturn V was the rocket that took the supplies, crew, and everything needed to get to the surface of the moon. The rocket is massive at 363 ft or 110 meters. The Saturn V was split up into 3 stages: S-IC, S-II, SIVB, and the lunar module, Service Module, Command Module, and the Lunch Escape S...

Why can't we crash all the nuclear or any waste into the sun?

Why don't we just crash all the waste that we made into the sun? It sounds a really good idea to take all the nuclear waste or any waste into the sun, right? The truth is it is harder to crash into the sun than to go to Pluto! Ask how? Reason #1 Well, this all has to do with the fact that the earth is spinning at a speed of 1000 miles per hour (1600 kilometers per hour). So, if you want to get to the sun, you have to go 1000 miles backward and then go to the sun. Just to show you how fast 1000 miles per hour, it is about 16.67 miles per second! So, get to get to the sun, you need to go 16.67 miles per second backward, and then go to the sun. That's why missions to the sun first went to Jupiter and then came to the sun.  Reason #2 Not only is it hard to get to the sun because of the spin of the earth but also because it is very dangerous to put all the nuclear waste into a spaceship because spaceships have a tendency to blast when lunching and if it explodes in ...
