Prior to his death on March 14, 2018, the English theoretical physicist created a theory that changed the way we think about the universe. Working with Belgian professor, Thomas Hertog, from the Katholieke Universiteit Leuven (KU Leuven), Hawking theorised that our three-dimensional reality is an illusion.
Put simply, Professors Hawking and Hertog speculated that all information in the universe is stored on a flat 2D surface and our so-called “solid” world around us is then projected from that information.
Back in 2018, Professor Hertog said: “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.
“The key point is that we're not projecting out a spatial dimension. We are projecting out the dimension of time from 'before' the Big Bang.”
Published a month after his death in the Journal of High Energy Physics, the theory is compatible with eternal inflation and Einstein’s theory of General Relativity.
Defining what makes a hologram, Professor Hertog explained that it can be viewed as a kind of dimensional change.
Professor Hertog added: “It's a theory that envisages a beginning to the universe where time is not present but our notion of time crystallises.
“And it's saying that time is fundamentally coming out of some other state for which we have no words.
“Some very abstract timeless state - that's the best we can do.”
Professor Hawking was a leading expert on string theory and quantum physics who helped piece together the ‘multiverse theory’ in which many worlds exist in parallel but each with its own evolution.
Despite adding great insight to the theory, Hawking was sceptical, once commenting in 2017 that he had “never been a fan of the multiverse”.
Professor Hertog said that before his friend’s death, Professor Hawking felt holography might offer a better understanding of the multiverse theory.
Professor Hawking said: “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.”
His final published theory is not the first to imagine the universe as a form of pseudo-existence as theories have arisen over the last few decades indicating that humanity is living in a ‘Matrix-like’ simulation.
In which case nothing matters.
Yeah...well probably you know more about magic mushrooms than I do since I know zero about them.
Hmmm
There is so much we don’t know!
Ah, the cushy life of a “great thinker”.
Only if the universe is closed.
Not sure it is, since the rate of expansion appears to be increasing.
“I lean toward a hemisphere supported by two giant elephants standing on a humongous tortoise. I don’t know what the tortoise is standing on. Needs a little more work.”
It’s four elephants on a tortoise. (Although there was one theory about a fifth elephant.)
Terry Prichard deserves the prize.
was he vaxxed for vexed?
The holographic universe theory that Hawking speculated is based on the string theory duality that was posited by Juan Maldacena known as AdSS/CFT. AdSS stands for anti de Sitter space named after the mathematician Willem de Sitter. The curvature of AdSS is negative like a Pringle chip unlike the universe we live in which has positive curvature.
Its an interesting mathematical tool used to bridge string theory calculations in eleven dimensions with quantum field theory calculations that include gravity but at this point it doesn’t describe the universe we live in.
“Were are the turtles?”
In the cosmic soup.
I think it was Hawkings who was a hologram. HE wasn’t real, just something a team of computer geeks with too much time on their hands produced; no chairs left in the string theory section.
The turtle moves.
1. ????
2. Nothing before the Big Bang. Time did not exist as there was nothing. It was eternity with out time and thus no measure of time.
3. Big Bang happened and thus the universe
Refer back to step 1. God is eternal and that concept we do not understand nor does any physicist, even Stephen Hawking. My theory is as good as Mr. Hawking’s theory.
Hah!
...and Hawkings is now a pimple on the ass of the hologram

LOL. Not I; I’ve never even gotten NEAR an illicit drug. Nor now, when some are legal.
By The Good Book, in this case, you mean Plato’s Dialogs? That is where the idea comes from, not the Bible. But most Protestant and Orthodox Christians think in a Platonic framework. RC follow Aristotle.
Only kind he could do. Well, that and with his nurse.
