To infinity and BEYOND!!!!

Ok well, apparently the blog I did on the weekend did not get posted, so here I go again.
Today's topic is about space travel and another documentary I saw on TV. It talked about the huge expanse of space and different ways in order to more efficiently get people into space and beyond. Currently, we use billions of dollars in order to turn stored energy into heat energy and do work through chemical reactions. But there could be other methods of getting people into space using some physics, some imagination, and some imaginary particles. The first idea would be to create a giant space elevator connected to the ground. This way all we would need to do is use electricity to pull up a giant room of people into space. We are getting closer to developing cords that are strong enough to withstand the velocities of a rotating planet and the space elevator would be perpendicular to the planet to reduce tension. Another idea is to create a space ship with huge sails, like thousands of miles in area, and using laser batteries on the moon to push the ship through space. Photons from the light actually can exert a force onto an object in space and a huge sail could collect this force and translate it into forward movement. Another idea is to use the idea that because super dense materials bend space-time, we can create a super dense material to pull one part of space closer to the ship and therefore reduce the time it would take to travel such a distance. This is somewhat analogous to instead of walking to a chair, using a lasso and pulling the chair closer to you. Instead of traveling faster to the chair, you are reducing the space between you and the chair. The fourth way to increase space travel dramatically would be through the use of an imaginary particle called tachyons. Tachyons are particles that work sort of opposite to normal particles. According to Einstein's equations and theorems, in order for an object to reach the speed of light, it would need infinite mass. However, tachyons have what's called "invisible mass", so instead of the speed of light being a maximum speed limit, it's actually a minimum. If we could turn a space ship into a tachyon like object, it would effectively become invisible to space time in terms of mass and travel at speeds faster than the speed of light. It's just too bad that tachyons violate the laws of conservation of energy, causality, and almost every other physics law known. Hahahaha, a man can dream can't he?
