Over the last three decades, theorists have proposed at least a dozen new approaches. Each approach is motivated by a compelling hypothesis, but none has so far succeeded. In the realm of particle physics, these include Technicolor, preon models, and supersymmetry. In the realm of spacetime, they include twistor theory, causal sets, supergravity, dynamical triangulations, and loop quantum gravity. Some of these ideas are as exotic as they sound.[/b]
And let’s not forget RM/AO.
What we have, in fact, is not a theory at all but a large collection of approximate calculations, together with a web of conjectures that, if true, point to the existence of a theory.
A theory in theory as it were.
Without having navigated waters shallow enough for us to see bottom, we’ll be easy prey to mystifiers who want to sell us radical metaphysical fantasies in the guise of science.
We’ve got a few of them here, don’t we?
Most kinds of matter are under pressure, but the dark energy is under tension—that is, it pulls things together rather than pushes them apart. For this reason, tension is sometimes called negative pressure. In spite of the fact that the dark energy is under tension, it causes the universe to expand faster. If you are confused by this, I sympathize. One would think that a gas with negative pressure would act like a rubber band connecting the galaxies and slow the expansion down. But it turns out that when the negative pressure is negative enough, in general relativity it has the opposite effect. It causes the expansion of the universe to accelerate.
At least until Don Trump drains the swamp.
Space and time emerge from the laws rather than providing an arena in which things happen.
One suspects however that they happen anyway.
I understood Einstein’s general theory of relativity, which meant that I knew how to demonstrate every essential property of it in a page or less of concise and transparent work. It seemed to me that if you understood a theory, it shouldn’t take weeks of calculations on an art pad to check its basic properties.
Let’s put your own theory to the test then.
