If your knowledge is lacking, historically…
A WMD stands for a Weapon of Mass Destruction. Commonly they refer to nuclear weapons: fission based and fusion based. Fusion based weapons are more powerful. I will talk about fusion based weapons. Because they make a bigger bang. I like big bangs.
Remember Hiroshima and Nagasaki?
Exactly. But fusion reactions are three to four times more energetic than fission. Therefore their destructive output is significantly larger. Add this to the fact that unlike fission that requires a critical reactant mass to happen, fusion can happen for an indefinite time, given that the right conditions are present. Therefore a fusion based weapon can lead to a potentially cataclysmic, near-apocalypse outcome.
But Lets think positively: Infinite Energy
That was an overstatement. But for humans, there is no difference. Fission (usually) requires Uranium-235. That isotope is only 0.72% abundant. On earth, there are an estimated 5.5 million tonnes of Uranium, which means about 36,000 tones of fissile Uranium. Compared to this we have about 4.68 trillion tonnes of oil reserves. Fusion, however, requires hydrogen atoms. Most of the hydrogen atoms on earth are tried up in water in the oceans. Compared to these two, we have 15 million trillion tonnes of hydrogen in the oceans. How’s that for unlimited?
…and Exploring the Ends of our Galaxy
Another overstatement. Poetic licence, you see. Anyways, NASA came up with a proposal about explosion propelled space ships.
They would have a thick metal shield at the back. At set intervals a nuclear explosion would be set off and the shock waves would accelerate the space ship. With each explosion, the mass of the ship would decrease and it would accelerate even more , eventually reaching relativistic speeds. That would technically allow us to access the stellar neighborhood, if not the entire galaxy.
Alas! Fusion’s too Good for our Technology…
Fusion requires extremely high temperatures (millions of Kelvin) to occur. And no material known to man can withstand the heat. Scientists are still experimenting with magnetic and inertial confinement. In magnetic confinement, the hydrogen plasma is confined within a solenoid so that it does not touch the surface or the container. In inertial confinement, beams of lasers heat up the particles in suspension to cause fusion. you can read more about these two methods here.
In the end, we’ll have to just wait for and see,
For a Genius of a Man to Solve the Mystery.
But if you really think that you are Worthy,
Step forth, Champion, and Tame the WMD!
Last semester, I took some poetry,
It seems some of it rubbed off on me.
I will stop now.
