Q: Is there a way, at least in principle, that the existence of multiple universes as described by you in Sci Am, can be experimentally verified or falsified? If not, as several of my colleagues have pointed out, it falls in the realm of religion and philosophy, but not physi...
parallel universes The Top Ten Breakthroughs of the Year in Physics December 13, 2024 Physics World is delighted to announce its Top 10 Breakthroughs of the Year for 2024, which includes research in nuclear and medical physics, quantum computing, lasers, antimatter and more. The Top Ten is the...
must describe the friend and the coin to be in a superposition of all possible outcomes of the experiment. That's because they are "entangled"—spookily connected so that if you manipulate one you also manipulate the other. Wigner can now in principle verify this superposition using ...
In both cases, the masses of the W± and Z bosons would be affected, potentially leading to different physics and potentially affecting the stability and creation. This path is being applied as you can find on the left sidebar. (Please change the view to desktop mode if you are on mobile...
Announcing Willow’s staggering performance speeds, Google’s Neven said the chip’s “mind-boggling” computation “exceeds known timescales in physics and vastly exceeds the age of the universe.” But if so, then how could Willow possibly perform at that rate?
and of the two the latter seems more likely to me, since there are also a lot of strong hints that chronology protection is also built into the laws of physics in a basic way (plus the difference between allowing 'hidden' backwards-in-time signals and allowing 'hidden' FTL signals seems...
Quantum physics is a linear theory, so it is somewhat puzzling that it can underlie very complex systems such as digital computers and life. This paper investigates how this is possible. Physically, such complex systems are necessarily modular hierarchical structures, with a number of key features...
The computer and the universe The reasons are briefly recalled why (1) time cannot be a primordial category in the description of nature, but secondary, approximate and derived, and (2)... JA Wheeler - 《International Journal of Theoretical Physics》 被引量: 113发表: 1982年 The Universe as...
High Energy Physics - TheoryPhysics - Popular PhysicsAs quantum theory celebrates its 100th birthday, spectacular successes are mixed with outstanding puzzles and promises of new technologies. This article reviews both the successes of quantum theory and the ongoing debate about its consequences for ...
It's sort of like quantum physics' answer to the old Zen question: If a tree falls in the woods and no one is around to hear it, does it make a sound? Since the Copenhagen interpretation says that, when observed, an object is forced to take one state or another, the quantum ...
