If you asked an astrophysicist today to describe what happened after the Big Bang, he would likely start with the concept of “cosmic inflation.” Cosmic inflation argues that right after the Big Bang — we’re talking after a teeny fraction of a second — the universe expanded at breakneck speed like dough in an oven.
But this exponential expansion should create, due to quantum mechanics, regions where the universe continues to grow forever and regions where that growth stalls. The result would be a multiverse, a collection of bubblelike pockets, each defined by its own laws of physics.
“The local laws of physics and chemistry can differ from one pocket universe to another, which together would form a multiverse,” Hertog said in a statement. “But I have never been a fan of the multiverse. If the scale of different universes in the multiverse is large or infinite the theory can’t be tested.”
Along with being difficult to support, the multiverse theory, which was co-developed by Hawking in 1983, doesn’t jibe with classical physics, namely the contributions of Einstein’s theory of general relativity as they relate to the structure and dynamics of the universe.
“As a consequence, Einstein’s theory breaks down in eternal inflation,” Hertog said.
The new theory – which sounds simplistically like the world of the red-pill-blue-pill Matrix movies – embraces the strange concept that the universe is like a vast and complex hologram. In other words, 3D reality is an illusion, and that the apparently “solid” world around us – and the dimension of time – is projected from information stored on a flat 2D surface.
“It’s a very precise mathematical notion of holography that has come out of string theory in the last few years which is not fully understood but is mind-boggling and changes the scene completely.“
“We are not down to a single, unique universe, but our findings imply a significant reduction of the multiverse, to a much smaller range of possible universes.“
“Stephen Hawking was beloved by everyone I know, both inside and outside the scientific community,” she wrote.
“He was a great man without doubt, but this paper is utterly unremarkable.”================================
Draai hierna (of wanneer het uitkomt) het geweldige album 'Pocket Universe' van Yello (als het goed is zie je rechts naast het eerste nummer de rest van het album staan, mocht dit niet zo zijn, klik dan op deze link en daarna op het eerste album dat je ziet >> zie na plaatsing van dit bericht dat je idd alleen het eerste nummer te zien krijgt en niet de rest van het album, klik dus op de link hierboven voor de rest van het album):
