^Mind blowing! I watched some fascinating programmes about the cosmos(BBC4) recently. Apparently the Earth has 6 billion years before it is consummed by our sun, and even the cosmos its self will die when stars run out of hydrogen to burn, and everything goes dark! It also showed how our four guys are actually a team, working together. Theoretical physicists come up with concepts(like White Dwarfs, or Super Massive Black Holes), which they then prove exist with maths, experimental physicists also come up with ideas but generally use experiments to prove, or disprove the concepts of theretical physicists. Astrophysicists also try to prove or disprove the concepts put forward by the other two, through observation of the cosmos, and analysing data. Aerospace Engineers then test the theories by designing, and building satelittes, and space craft(incl:telescopes), that can actually see, or go and test the theories.
