The smallest thing ever!!!!

Atoms are the smallest things that we can imagine, and they are the building blocks of everything we know and love. The range of its mass is 1.67 × 10−27 to 4.52 × 10−25 kg, that’s extremely small. Things we think are solid actually aren’t because atoms are mostly empty space, they are a condensed piece of matter in the middle and electrons float around it, but it is mostly empty space. So solid things aren’t actually solid at the atomic level, and atoms are in constant movement, they are always vibrating and colliding with one another. The never ending movement of atoms is what gives them the ability to make objects seem solid, and lets say that we could stop the movement of atoms completely on an object, then in theory you would be able to go right through the object because the atoms aren’t colliding and moving so you would be able to literally push them apart and go through any object, but to attain that we would need to be able to produce "absolute zero" which is zero Kelvin and -273 degrees Celsius, and if we were able to reach that temperature, atoms would stop to move, but its practically impossible and we’ve only come 99.9% of that. The atoms mass is mostly concentrated at the center which is made up of protons and neutrons, which are positive and negative respectively. The outer part of the atom is composed of electrons which are negative and located in the electron cloud. The nucleus or center of the atom is relatively small compared to the rest of it, if a marble was a nucleus then an entire football field would be the atom. So are the smallest things we know and make up everything we know.

UFO's!!!!!!!

UFO's stands for unidentified flying object. People have been reporting UFO citing for years, there’s even shows that try to prove the existence of UFO's such as "ufo hunters" on the history channel. They have been one of the greatest mysteries of human kind.

Everyone has there own beliefs of what an alien could look like, and most of the images in peoples heads are green shaped beings with black beady eyes. Well they would look weird but not the image that they are portrayed as. They would be carbon based and they would look like organisms that live on our planet, were not sure exactly how but that’s close enough. Their craft would also be unknown because they wouldn’t necessarily be disk shaped, most UFO cititngs have been triangular or just an arrangement of lights. We don’t know if they really exist, but personally I think they do, we just haven’t seen one because the universe is infinitely huge and to get here from another galaxies would take millions of years. But I do think they exist because there are a lot of planets in the universe that resemble earth and it wouldn’t be that surprising to find another planet that looks like earth and could be habitable. There has been thousands of UFO citing and maybe one day we'll get to know what they really look like, because it has to be almost a certainty that they exist.

What is our sun?

http://www.youtube.com/watchv=x1w8hKTJ2Co&feature=related First of all watch his video because itl blow your mind, and make you think how small we really are.

We are actually very tiny in the universe, our sun which appears to be so big is actually also very small. Even though it is really small in comparison to all the things in the universe, it is relatively far, lets say that the sun was to completly shut off, we wouldnt see any change for eight minutes because thats how long it takes the light from the sun to get here. The sun is extremly hot, at the surface its 10,000 degrees farenheit and its about 27 million degrees farenheit at its core. The sun is composed of 75% hydrogen and 25% helium, its not very complicated. It works and makes the energy and light it provides by a thing called fusion, its where it takes a hydrogen and helium particle and fuses it together to produce light and energy. Fusion would be the best way to make energy on earth but we havent found out how to do it yet, all we can do is fission which splits an atom in half and produces energy but it emits bad radiation, fission takes place at nuclear stations. Once the sun runs out of gases to do fusion with, it will basicly turn off and imploded over the weight of its own gravity and in turn make a black hole, but that wont happen for at least 5 billion years. The sun isnt a very complicated thing but it is what makes life on earth possible because it provides us with heat, light, and energy which is hwat every living thing needs.

How our planet was made!!!

Our planet was created about 4.27 billion of years ago in a very simple way. Around that time a supernova exploded (a supernova is like a gigantic star, its like 46 times bigger than the sun). When it exloded it sent out a wave of matter whichi was attracted by our suns gravity. Once it was attracted to our sun, the matter started whirling around and clashing togehter to form burning bodies of hydrogen and helium. Then the suns gravity made it able to gather gaseous clouds of matter which started to clash into each other, and when they did they stuck together and became extremly hot. After a while planets and astroids would start to form and eventually earth was made. But at first it was a massive ball of hot rock that was just crumpled together, and after a long time it cooled down and water was able to form because of our atmosphere that was created in the process from all the gases floating that were realeased from the center. As the earth cooled all the metals sunk to the center, thus creating the earths iron core, and it became round beacause of gravity. The center contained water vapor, carbon dioxide, sulfur, nitrogen, argon and chlorine, when it speud up out from the center an atmosphere was made, and thus waster was formed later on. The reason for us having an atmosphere and not the other planets it was because earth was lucky to get the collisions it got and the perfect distance from the sun to make carbon dioxide and oxygen (our atmosphere). So were actually lucky that our planet is even here.

Whats outside?

We all think the universe is infinite and never ending, well thats wrong. The universe is finite, and there is something on the ouside of it. We know this for sure because we know that at one point the universe was a singularity and then it exploded and expended, well its still expending but it is expending in something, and one day it might stop expending and retract but thats for another blog.

So we basicly know for sure that there is something outside the universe but we jsut dont know what it is for sure. There are many theories to whats on the other side of the universe but mostly all answers lead back to one thing, antimatter. Antimatter is actually the opposite of matter. It basiclly cancels out the matter thats in our universe and all the other universes if there are other ones. So antimatter is whats on the ouside of our universe, it just counters the matter that we have in our own.

If there is more than one universe then they all live or reside in an infinite amount of antimatter which counters the matter in the infinite amount of universes. Different universes are basiclly like globs that float next to each other in this infinte amount of antimatter. So you couldnt physically come out of our universe because on the other side there is already antimatter to cancel you otu so you wouldnt actually be able to go out, it would be kind of like a barrier, or at least thats what i think. But before we could even get close to the edge of the universe it would be trillions upon trillions of light years away before you could get there.

How many universes really exist?

Many scientists think that there isnt just one univere but an infinite amount, and some think that there are actually 27 universes, but one think is sure and thats no one knows exactly how many there are.

The thoery of an infinite amount of universes is mind blowing. The thing is that scientisits think that in each universe only one insignifigant thing happened differently. Lets say that one piece of grass blows to the left because of the wind, well an other univerese the only difference is that that piece of grass moves to the right, and thats a completly different universe. So you can easily see how many there are if thats true, then there is an infinite amount of universes becuase an infinite amount of different things can happen.

The theory on 27 universes says that there is actually only 27 of them. Each one operates on a different dimension, meaning that theres a universe that actually moves in 27 different ways, and also another that only moves in one. To explain this, we live in a three dimensional world, we move forward and back, side to side, and up and down, thats three dimensions. Now the universe with four dimensions would move the same way we do and another way which scientists theorize is through time itslef. But there is also a universe that can only move in one dimension, forwad and backwards, and they would have zero thickness because the other ways wouldnt exist. So there could be 27 universes that move in 27 different dimensions.

Asteroids

Asteroids are basiclly just giagantic rocks in space. They are basicly dust, metal, and rock that travel at very fast speeds. They can be huge but if an astroid is an astroid then it is too small to be called a planet, so they are actually mini planets. Thousands of astoids hit the earth every day, but before they can actaully make contact they burn up in the atmosphere. There is a thoery that an astroid wiped out the dinosaurs, a great a mighty race, but the truth is that the astroid which indeed did hit the dinosaurs just hit at a very low point in their exsitence thus wiping the out. There a gigantic craters in the earth that have been made by astroids hitting the earth, some of them are as big as 300 km in diameter. Truth is that earth has been hit by asteroids multiple times, and sometime by thpusands of astroids at the same time, thats because sometimes the asteroid belt in our solar system located between mars and jupiter, it is 370 million miles long, and the main belts are called Gaspra and Ida. We can prove that a lot of asteroids have hit at the same time becaue once every couple millions of years the asteroid belt loses a lot of asteroid that go everywhere, and you can tell this is true because if you look at the moon it has thousands of craters created by asteroids. If a big asteroid did hit earth it would be catastrophic, because not only would it wipe out 1/2 of the population right away but it would throw our planet into another ice age. Lets say that an asteroid was going to hit earth we would know even a 100 years in advance the exact day of the end of humanity, as it would come in it would be so hot (they travel at maybe 100 miles per second) that the fire would be, not red, not blue, not green, but purple, and if you were close enough that your eyes would be able to see it, you would disintegrate right away from the intense heat. But luckly for us, we wont have an asteroid hit us for a lot of generations to come. But if there would be an asteroid coming within the next one hundred years we might actually have the technology to send it away, but if it was a comet we would have no chance.

Galaxies

Galaxies are enormous, and composed of thosands of solar systems. Our galaxie is called the milky way, and we are actually very far off from the center. We are at the edge on a spot called orion spiral arm. There is about 100 billion other stars in our galaxie. The Sun is revolving around the center of the Galaxy at a speed of half a million miles per hour, yet it will still takes 200 million years to go around once. (thats big). The milky way is roughly 10 billion years old. Our galaxie is about 100 000 light years in diameter. Our planet is 26,000 light years away from the center.

Galaxies look like huge spirals. Scientists theorize that there are black holes at the center of galaxies, ours is called Sagittarius A*, and these black holes are actually extremly massive. Galaxies are composed of mainly three parts, The halo a spherical distribution which contains the oldest stars in the galaxy, the nuclear bulge and galactic center which is usually brighter than the other parts, and the disk, which contains the majority of the stars, including the sun, and virtually all of the gas and dust. About two million galaxies have been actually couted in the universe but there could be 100,000 million. There are many galaxies out there, with maybe other life forms but to try and even comprehend how huge our galaxie actually is, its incredible to think that there are so many other ones out there.
