Parallel Realities, The Multiverse And Consciousness
Posted by Dave Holt in categories: cosmology, robotics/AI
I have had this theory for a while and it fits my simulation theory but now seems like the perfect time to discuss it, given the research and findings from the Blue Brain Project. Please send me an email after reading this and let me know what you think of it? Thanks.

Faux particles commit physics faux pas

“For example, Hasan says, “we can test theoretical ideas in the early universe,” simulating how particles may have behaved just after the Big Bang, when Lorentz symmetry may not have been obeyed.”
It’s interesting how often I hear condensed matter physicists justify their work by saying “might be important for something with quantum gravity” while condensed matter physics by itself is much more likely than quantum gravity to be good for something.

Quantum Computers and Parallel Universes
Posted by Dave Holt in categories: computing, cosmology, quantum physics
We have a highly respected Theoretical Physicist and a pioneer of Quantum Computing, along with the Founder of one of the leading quantum computer companies, D-Wave (whose clients include Google and NASA), talking about parallel universes. Here is a key that I discovered. They are not talking about parallel universes as a theory but as something factual that exists.
An amazing article on the ability of a Quantum Computer to exploit parallel universes. This article is a MUST READ!

Solar System Map: Surprisingly deceptive

What’s wrong with this illustration of the planets in our solar system? »
For one thing, it suggests that the planets line up for photos on the same solar ray, just like baby ducks in a row. That’s a pretty rare occurrence—perhaps once in several billion years. In fact, Pluto doesn’t even orbit on the same plane as the planets. Its orbit is tilted 17 degrees. 
So, forget it lining up with anything, except on rare occasions, when it crosses the equatorial plane. On that day, you might get it to line up with one or two planets.
But what about scale? Space is so vast. Perhaps our solar system looks like this ↓
No such luck! Stars and planets do not fill a significant volume of the void. They are lonely specs in the great enveloping cosmic dark.* 
Space is mostly filled with—well—space! Lots and lots of it. In fact, if Pluto and our own moon were represented by just a single pixel on your computer screen, you wouldn’t see anything around it. Even if you daisy chain a few hundred computer screens, you will not discern the outer planets. They are just too far away.

Scientists detect Einstein gravitational waves for a third time
Posted by Dan Kummer in categories: cosmology, physics
N” Scientists have for a third time detected ripples in space from black holes that crashed together billions of light years from Earth, a discovery that confirms a new technique for observing cataclysmic events in the universe, research published on Thursday shows.
Such vibrations, known as gravitational waves, were predicted by Albert Einstein more than 100 years ago and were detected for the first time in September 2015. They are triggered by massive celestial objects that crash and merge, setting off ripples through space and across time.
The latest detection occurred on Jan. 4, 2017. Twin lasers in Louisiana and Washington picked up the faint vibrations of two black holes that were 20 and 30 times more massive than the sun, respectively, before they spiraled toward each other and merged into a larger black hole.

The “Door’ To Another Universe…Can We Find The Black Hole That Opens It…Physicists Say “Yes!”
Posted by Andreas Matt in categories: cosmology, information science, mathematics, physics
According to a mind-bending new theory, a black hole could actually be a tunnel between universes, meaning our universe may be nested inside a black hole that is part of a larger universe. The theory explains that the matter doesn’t collapse into a single point, but rather gushes out a “white hole” at the other end of the black one.
The theory was published in the journal Physics Letters B, by Indiana University physicist Nikodem Poplawski. In his article, he presents new mathematical models of the spiraling motion of matter falling into the black hole. His equations suggest that wormholes are probable alternatives to the “space-time singularities” originally predicted by Albert Einstein.
Einstein’s equations for general relativity suggest singularities are created whenever matter in a given region gets too dense as would happen at the center of a black hole. Singularities are infinitely dense and hot, and take up no space. This idea has been supported by indirect evidence but has never been fully accepted into the scientific community.

Do stars fall quietly into black holes, or crash into something utterly unknown?
Posted by Andreas Matt in category: cosmology
Astronomers at The University of Texas at Austin and Harvard University have put a basic principle of black holes to the test, showing that matter completely vanishes when pulled in. Their results constitute another successful test for Albert Einstein’s General Theory of Relativity.
Most scientists agree that black holes, cosmic entities of such great gravity that nothing can escape their grip, are surrounded by a so-called event horizon. Once matter or energy gets close enough to the black hole, it cannot escape—it will be pulled in. Though widely believed, the existence of event horizons has not been proved.
“Our whole point here is to turn this idea of an event horizon into an experimental science, and find out if event horizons really do exist or not,” said Pawan Kumar, a professor of astrophysics at The University of Texas at Austin.
