G2G,
Rambles told us that s/he never went past Point Zero (which is why s/he couldn't teach beyond it), but that s/he knew some others that did go "into" Pt. 0. Poor R was stuck with us low lifes on this side of the void and s/he couldn't break away from us to go. So, Rambles doesn't know what's on the other side of Pt. 0. That'll have to be another lifetime for the Big Guy/Gal. LOL
Check this out:
"An enormous idea
So we come away with the incredible thought that the solar system?and the rest of the universe?might be filled with tiny black holes, each carrying the signature of the fourth dimension. And in the next year or two, GLAST should make it possible to look for them. It is worth noting that if we don't see the characteristic interference patterns right away, it doesn't automatically mean braneworld gravity is wrong; it could just mean primordial black holes are rare.
If we see even one case of interference, though, that's when the fun begins. We would immediately know that tiny black holes exist. We would need to analyze the data carefully before drawing firm conclusions about gravity. But we would dive in with gusto, knowing that we were on the trail of something physically small but philosophically enormous. As large, perhaps, as a whole new dimension of space.
Your neighbors could have a pet black hole, and you might not realize it.
A close relationship exists between the mass of a black hole and the wavelength of light it can affect. If the Randall-Sundrum model is correct, tiny primordial black holes could exist and produce interference patterns in light from the short-wavelength, gamma-ray portion of the electromagnetic spectrum. By contrast, if general relativity is right, no primordial black holes below a few hundred million tons should remain, and hence no interference patterns should appear in gamma-ray light.
After calculating the interference effect, we scratched our heads and asked each other, Is there any hope of measuring it? We knew that tremendous natural explosions in deep space called gamma-ray bursts produce light of the right wavelength. The question was whether any telescope today could measure this light.
It turns out that the perfect telescope is on the way: the Gamma-ray Large Area Space Telescope (GLAST), which is scheduled to be launched on a spacecraft in August 2007. A joint effort among NASA, the U.S. Department of Energy, and institutions in France, Germany, Japan, Italy, and Sweden, GLAST will be exquisitely sensitive to high-energy gamma rays?and able to measure interference effects from any primordial braneworld black holes."
