As of this year, here's some "theories" that bother me.
1) String theory.... really whacked out
2) Membrane theory... Bliksem!
3) Dark matter maybe doesn't actually exist, so we should stop looking for it.
4) Something last week about the universe is contracting not expanding....Huh?
5) Carbon tax ....In Africa....?
6) the solar maxumum in 2012
7) Why my BMW leaks oil and no amount of money or gaskets will stop it.
String theory is a very elegant and difficult mathematical theory.
It offers the GUT or the Grand unifying theory which will eventually bridge the gap in combing Quantum theory and Gravity. (or Intelligent falling as some believe) Read The Elegant Universe by Brian Greene.
Membrane theory is very much a hypothesis at this time, but it is an exciting new train of thought.
Einstein's equations originally indicated that the universe was either contracting or expanding. At that time, every one believed the universe was static. Hence Einstein introduced the cosmological constant to make his equation fit the current belief, which he later called his biggest blunder.
Later observations by Edwin Hubble proved that the universe was expanding.
As for dark matter, there is strong empirical evidence for dark matter and dark energy.
Curved space really just means that gravity has an effect on thelight. In the presence of large masses, the gravitational forces exerted by this mass will cause light to bend, but as we know, light travels in a straight line. Think geodesics and rhumb lines.
John Wheeler coined a phrase, " Mass tells space how to curve and space tells mass how to move". An exaple would be, from our point of view, earth travels in an eliptical orbit around the sun, but as far as the earth is concerned it travels in a straight line.
All this is of course a bit more complex than the internal combustion engine.
As to you BMW leaking oil, use a thicker oil..

climate change is real, go and ask the people living in the Garden Route.
Conspiracy theories are nothing more than :bs:
