String theory is the best candidate we have for all theories. Bends to that rule, various entangled theories of traditional physics emerge as part of a sublime, higher-dimensional tapestry. It can unify all four of nature, including the most troublesome gravity of all. If you're lucky, you might even tame big bangs and black holes without losing threads.
There's only one catch. String theory cannot explain the universe like ours. That mathematics can explain billions of different possible universes, but not expanding at speeds of acceleration, it's exactly what we see. Certainly, no one knows that this acceleration is driving. Mystical “dark energy” is the usual placeholder. According to theory, it probably shouldn't happen at all.
For 25 years, this was a big problem, but now I may have found a way past it. On the surface, the answer does not shock anyone who is used to the luxury of modern physics. We need to rethink the universe as part of a much larger company. Doing this can bloat into the content of your mind. In fact, the acceleration of expansion seems to come naturally. However, this new scheme could be the wildest scheme ever. Our familiar spaces are delicately settled between high-dimensional hyperspace and total meaninglessness. “Our proposal says that our existence is like a shadow: a projection onto a wall at the end of the world.” Antonio Padillaa physicist at the University of Nottingham in the UK.
For all the grandeur of the present, the string…
