Aluminum Foam

In science, there is a new concept of using metals. It is aluminum foam. It intigrates the property of air, and aluminum together. This foam is very usefull because we can use it in buildings. It is shock-absorbant. In case or a bomb, or just an explosion of the building gas line, the aluminum foam will absorb most of the explosion. Know how? Take your hand and run it through the air. What do you feel? No impact, right? But now take your hand and hit it against a solid. You felt the solid, but what if the force of your hand was so strong that you broke it? Same principal with buildings! You can't break the air, so why not make buildings out of air? And that's what we're doing! However, this aluminum foam is hard to make. One needs to soak a block, or sheet, of aluminum in an extremely hot, corrosion-resistant substance, soak it into another chemichal solution, in a special tank that lets out bubbles, and spreads them evenly. Making this foam is not easy, but the result is worth it.

Dark Matter

What is Dark Matter? Dark matter is the stuff from space that we don't see, but we can tell it exists. We can't see it because it dosen't reflect light the right way. In fact, we can't see about 70% of the universe, for it is dark matter. As it turns out, this dark matter saved our lives! A long time ago, the universe started to expand, and the dark matter, using all its gravity, pulled it together. Everything that we have seen from Earth is only 5% of what is really out there! Just to give you an idea of what remains unexplored. Some things are influenced by dark matter. Such as the stars from the spiral galaxy. They are moving too fast for them to be natural. We have proof of that besause two galaxies: M51 and NGC5195 are so close to each other, that their gravitational forces affect each other's stars. As you might already guess, there is also bright matter. Bright matter is what we can see, and reflects light the right way, but not nearly as mysterious as Dark Matter.

Antimatter

Look in the mirror. What if the person you see actually existed? Well, he might! Scientists think that in a different universe there is a planet just like ours, in a solar system just like ours, in a galaxy just like ours in, a universe just like ours! Think of it like the universe is looking into a mirror, except the image is real. We want this antimatter because it can produce a ton of energy. Enough to launch a space shuttle 10 times! It could be a completely new source of energy! But we have to be careful, because if one full atom of matter comes intact with it.. Oops! Nuclear explosion! That is what they are doing at C.E.R.N. world's largest study of particle phisics(see blog below). There is a theory that when they get to close to each other, they explode because particles get excited, they generate so much heat, they release so much energy, that they blow up. Like all regular atoms, antimatter atoms have antiprotons, antineutrons, antielectrons, and antinucleuses.

Particle Accelerator C.E.R.N

People at the Particle Accelerator shoot particles around a huge tube. When the particles hit each other, they create more particles. Their goal is to create Antimatter, Dark Matter(see blogs above),or recreate the Big Bang, to see how we were created. However, this project is expensive. 8 billion dollars just to build it, and the parts.
