A visualization of QCD illustrates how particle/antiparticle pairs pop out of the quantum vacuum for... [+] very small amounts of time as a consequence of Heisenberg uncertainty. Instead of matter and antimatter particles, the researchers used pairs of phonons, or quantum sound waves, in the gas flow. These diagrams may show particles and antiparticles popping in and out of existence, but that is only a calculational tool; these particles are not real. "Those could still be 1% to 10% of dark matter … and there's still a window at lower masses, like the mass of a very small asteroid. Stay up to date on the coronavirus outbreak by signing up to our newsletter today. Hawking’s paper appeared online last week on an online server for research articles operated by Cornell University called arXiv. The major problem with Hawking's explanation of his own theory is that he takes a calculational tool — the idea of virtual particles — and treats that tool as though it's equivalent to physical reality. But this appears to violate a bedrock concept of quantum physics, the rules that describe how the universe works at the atomic and subatomic levels.
