ohwilleke thank you for an intelligent and unemotional response, same to the others on this list. For those of us who have limited maths and a real curiosity but are still capble of "good and productive thinking" (thanks for that line arildno) without it. As a poet I'm aware of a variety of ways of thinking/feeling that seem in my limited knowledge not easy to fit into math and yet are still important and productive for insight. I look at some of the theories as mentioned about the hawking radiation and other things, like the big bang, string theory and the brane with multiverses and wonder about them when there seem to be simpler solutions possible like an eternal universe. Now I have heard about the acceleration of the universe and people madly looking for some explanation but some this stuff seem as sloppy as New Age thinking
I would distinguish speculative and sloppy.
The bottom line issue is that simple solutions do not work. Life would be great if you could explain all there was to know about gravity with F=GMm/R^2. Alas, nature has not been cooperative. It turns out that to correctly determine the effects of gravity you need godawful rank two tensors, pressures, and a rethinking of the basic nature of time and space and all other sorts of stuff that is hard to get a handle on even with a graduate education in physics.
The famous line "who ordered that?", pretty much sums up quantum mechanics. Back when we had just protons, neutrons, electrons and classical electromagnetic fields we were pretty proud of ourselves. This plus gravity explained virtually everything our eyes could behold. At the tail end of the 19th century the were talking about all future advances in physics coming in the nth digit.
Then, a few slight cracks appear in the edifice. In a single lifetime, we go from the simple models of classical physics to a world with six kinds of quarks, three colors, three kinds of neutrios, two additional fundamental forces, three kinds of electrons, gluons, Ws, Zs, photons and probably a few malingerers that we haven't found yet. And, don't get me started about what a revolutionary concept it is to go from the deterministic, continuous classical physics universe to a universe where absolutely fricking everything in the universe is random in an extremely pure sense and physical phenomena act differently when people are or are not looking at them.
And, neither Hubble nor anyone else expected to discover the Big Bang. The whole eternal universe gig was looking pretty good in 1900. Keep in mind that the very term "Big Bang" was invented as a term of derision by a Big Bang skeptic promoting a steady state model of the universe, and not by Big Bang proponents.
When experience repeatedly shows you that the universe is far more weird than you'd ever expected it to be, naturally, you become more open to weird approaches to explaining what is out there.
Are people madly looking for solutions? Yes.
Will the theories on the cutting room floor when we're over look like the remains of a ticker tape parade? Yes they will.
But, every one of these published theories is a plausible, fairly rigorous, connected to some heartland of physics approach.
OK, some of the theories are a little over the top. No, lots of the theories posit really strange things. And, as a general rule one wants to avoid believing in theories that involve really strange things (not that the humanities have ever had a problem with really strange things). But, I sincerely believe that somebody is on the right track.
If you want to know which theories are most on the right track, contact your local bookie.
