Mindblowing stuff. Apparently, not all the constants in the universe are constant throughout the universe.
The Anthropic or Fine-Tuning principle may be even stranger than we thought:
Our solar system is in a unique area of the universe that's conducive to life, says John Webb and his colleagues at the University of New South Wales, who have carried out intensive study that threatens to turn the world of theoretical physics upside down.
The team studied the fine structure in the spectral lines of the light from distant quasars from data from the Very Large Telescope (VLT) in Chile with stunning results that showed that one of the constants of nature --the Alpha appears to be different in different parts of the cosmos, supporting the theory that our solar system is in a part of the universe that is "just right" for life, which negates Einstein's equivalence principle, which states that the laws of physics are the same everywhere.
The "magic number," known as Alpha or the fine-structure constant, appears to vary throughout the Universe, concluded the team from the University of New South Wales, Swinburne University of Technology and the University of Cambridge.
"What they found threatens to turn the world of theoretical physics upside down," said theorectical physicist, Paul Davies of Arizona State in an article in Cosmos this past January. "On the face of it, α has slightly different values in different parts of the Universe, implying that the fine structure constant is not a constant at all, but varies over cosmological distances and times."
"This finding in 2015 was a real surprise to everyone," said John Webb of the University of New South Wales in Sydney, Australia. The change in the constant appears to have an orientation, creating a "preferred direction", or axis, across the cosmos, an idea that was dismissed more than 100 years ago with the creation of Einstein's special theory of relativity.
“After measuring alpha in around 300 distant galaxies, a consistency emerged: this magic number, which tells us the strength of electromagnetism, is not the same everywhere as it is here on Earth, and seems to vary continuously along a preferred axis through the Universe,” said Webb.
“The implications for our current understanding of science are profound. If the laws of physics turn out to be merely “local by-laws”, it might be that whilst our observable part of the Universe favors the existence of life and human beings, other far more distant regions may exist where different laws preclude the formation of life, at least as we know it.
“If our results are correct, clearly we shall need new physical theories to satisfactorily describe them.”
The researchers' conclusions are based on new measurements taken with the Very Large Telescope (VLT) in Chile, along with their previous measurements from the world’s largest optical telescopes at the Keck Observatory, in Hawaii.
