Everyone in modern society knows about the space program, and many, many people do not support it. They probably think that we need to worry about our own problems, here on earth, before we start thinking about collecting some dirt from the moon or mars. Well there is one thing that is almost guaranteed about these people; they don’t know the facts.
Next to all that the universe has to offer, the earth is nothing. The power of the universe is incomprehensible, as I will explain shortly, and there are so many resources in just the surrounding planets, that it is amazing to think that we have so much trouble finding energy on earth. Think about it; what are we going to do when we use up all the oil on the earth? Turn to water for fuel? How about when the water becomes polluted? We need to find new fuels and energy-suppliers, which we aren’t coming close to doing at the moment. Now, if we turned to mars, we could at least have water for many millenniums to come. If oil or any other form of fuel is found on mars, we could also be powered for a long time. So, yes, I realize we need to focus on our own problems, but everyone needs to open their eyes and see that the answer is right in front of them (or above them, depending on the time).
Another concerning factor about stopping or slowing the space program is that the solar system isn’t going to be here forever. The sun is going to die or “burn out” eventually. However, there is a catch. When stars die, they don’t simply go out and disappear. No, God had fun creating stars. long before the sun dies (which will happen in another 5 billion years, but don’t procrastinate yet) it will start to run out of hydrogen to burn up. It will get hotter and brighter, but it will also begin to shrink. Now the sun’s gravity is what keeps us close to it, and this sun’s gravity depends on its mass. so since it is getting smaller, the gravity will decrease. This also means that we will start to move further and further away from the sun (so the hotter and brighter thing doesn’t really even matter to us). But don’t worry, you wont have to live like this for too long. The earth will soon turn into a frozen wasteland in which nothing can survive.
Once the sun does eventually use up all its hydrogen, it will collapse onto itself because it has no more power pushing itself out. It will then reverse its old process, and will be fusing helium (which it was producing) back into hydrogen and carbon. Now this produces a heck of a lot more power than the old method, and the sun will expand at amazing speed. it will engulf all the planets, first mercury, then Venus, and what’s next? you guessed it, earth. But those few hypothetical survivors of the ice age will be in luck. They won’t have to experience it. They will have a few years of enjoyment after the planet thaws, and then all the rivers and oceans would evaporate and they would almost literally boil to death. Sounds fun, right?
And now, for the grand finale. Once the sun reaches a certain size, It will no longer have enough gravity to hold itself together, and the sun will explode into a big ol’ fireworks display. Of course, it will be accompanied by super hot gases and radiation flying everywhere, which would just add to the excitement. Now, sticking to the theme of hypothetical survivors, after the explosion, everything wouldn’t be fine and dandy. The sun would reform into a white dwarf, about the size of earth, but with the mass of a star. This means that it is so dense that a cubic centimeter of a white dwarf could weigh a few tons! This also means that the gravitational pull is enormous, so you wouldn’t even be able to fly away in a ship. The reason it is a ‘white’ dwarf is because it is superheated, and it is slowly cooling down. Eventually, it would become a black dwarf, which is how it would stay; cold, black, and barren. So those hypothetical survivors wouldn’t have very fun lives from then on.
As you can see (in great detail) there are very good reasons why we need to continue the space program. I know it doesn’t make much sense, but if we want to stay on this earth, we have to expand away from here. Also, if we want the human species to be alive at all for years and years to come, we need to expand away from here. The only way to do that is by funding the space program.
