Scientists continue to argue about why the universe is still expanding. According to the big bang theory, gravity should eventually cause that expansion to cease, and everything will then collapse back in on itself.
The problem is, however, that there is no sign of that happening. In fact, new evidence seems to suggest that the rate of expansion is actually continuing to accelerate, and scientists are baffled as to why. But in an effort to hide their ignorance, they come up with fancy terms like dark matter and the Cosmological Constant to try and make sense of it all. But guess what? Those are nothing more than just more theories.
It is time for the so-called "scientific establishment" to admit the uncomfortable truth: Astronomy is nothing but an unproven theory, and our institutions of higher learning should instead start teaching astrology.
