Asimov’s favorite of his short stories, and widely regarded to have an astonishing ending.

A gravitational space-time detector picked up extra noise, which has made some theorize that our entire universe is a hologram.

This is insanely fascinating, and I honestly don't understand it at all. "In addition to its phantomlike nature, such a universe would possess other rather startling features. If the apparent separateness of subatomic particles is illusory, it means that at a deeper level of reality all things in the universe are infinitely interconnected." "We are really "receivers" floating through a kaleidoscopic sea of frequency, and what we extract from this sea and transmogrify into physical reality is but one channel from many extracted out of the superhologram."

"The Chandra X-ray Observatory, which was launched and deployed by Space Shuttle Columbia on July 23, 1999, is the most sophisticated X-ray observatory built to date. The mirrors on Chandra are the largest, most precisely shaped and aligned, and smoothest mirrors ever constructed. Chandra is helping scientists better understand the hot, turbulent regions of space and answer fundamental questions about origin, evolution, and destiny of the Universe. The images Chandra makes are twenty-five times sharper than the best previous X-ray telescope."

"...if the project is successful, the space-time around a tiny point within our universe will be distorted in such a way that it will begin to form a new superfluid space, and eventually break off..."
