Science Says the Universe Could Be a Hologram, Computer Program, Black Hole or Bubble

What is the Universe? A hard question to answer , no doubt, but Smithsonian Magazine suggests there are ways to check:

The questions are as big as the universe and (almost) as old as time: Where did I come from, and why am I here? That may sound like a query for a philosopher, but if you crave a more scientific response, try asking a cosmologist.

This branch of physics is hard at work trying to decode the nature of reality by matching mathematical theories with a bevy of evidence. Today most cosmologists think that the universe was created during the big bang about 13.8 billion years ago, and it is expanding at an ever-increasing rate. The cosmos is woven into a fabric we call space-time, which is embroidered with a cosmic web of brilliant galaxies and invisible dark matter.

It sounds a little strange, but piles of pictures, experimental data and models compiled over decades can back up this description.

Best Explanation of Quantum Field Theory That You Will Ever Hear

via chycho


Below you will find an excellent lecture by Dr. Sean Carroll delivered on 12 June 2013 at the 46th Annual Fermilab Users Meeting, focusing on the importance of the discovery of the Higgs boson confirming the existence of the Higgs field – giving us a glimpse into the world of “Particles, Fields and The Future of Physics”.

For me, the highlight of the lecture occurred during the question and answer period, at approximately 1:14:32, when one of the members of the audience asked the following question:

Question: “So, could you explain a bit more on measurement? You said that you have wave and it interacts with an entangled amount of waves and then pops out a particle, right?

I found the following response by Dr. Carroll to be the best description of quantum field theory that I have ever come across:

Sean Carroll: “Yes.

A Universe Not Made For Us: Carl Sagan on religion, geocentrism

I’d like to share this with you, even though some may choose to take the words of a celebrated, successful, and dead  person as a threat to their perspective. If you are open to what he had to say, you may notice the open nature of the use of may. His words on subjectivity, may not be viewed as a shut down, but as a warning.

A Universe Not Made for Us

Video by Callum Sutherland

Our ancestors understood origins by extrapolating from their own experience. How else could they have done it? So the Universe was hatched from a cosmic egg, or conceived in the sexual congress of a mother god and a father god, or was a kind of product of the Creator’s workshop—perhaps the latest of many flawed attempts. And the Universe was not much bigger than we see, and not much older than our written or oral records, and nowhere very different from places that we know.

New Compelling Evidence Suggesting The Universe Is A Hologram

hologramIn existential news, Tupac isn’t the only one who may merely be a flat holographic projection. Via Nature:

A team of physicists has provided some of the clearest evidence yet that our Universe could be just one big projection.

In 1997, theoretical physicist Juan Maldacena proposed an audacious model of the Universe in which gravity arises from infinitesimally thin, vibrating strings. The mathematically intricate world of strings, which exist in nine dimensions of space plus one of time, would be merely a hologram: the real action would play out in a simpler, flatter, single dimensional cosmos where there is no gravity.

Maldacena’s idea thrilled physicists because it solved apparent inconsistencies between quantum physics and Einstein’s theory of gravity.

In two papers posted on the arXiv repository, Yoshifumi Hyakutake of Ibaraki University in Japan and his colleagues now provide, if not an actual proof, at least compelling evidence that Maldacena’s conjecture is true.

Are Strange Distant Stars Evidence Of Super-Advanced Lifeforms?

starivoresVia the Huffington Post, evolutionary anthropologist Cadell Last argues that we are failing to recognize what we see:

Philosopher (and systems theorist) Clément Vidal has pointed out that there are certain binary star systems that astrophysicists have had difficulty explaining with conventional astrophysical models. These binaries are semi-detatched stars that exhibit an energy flow that is irregular, but not out of control. Vidal argues that instead of an astrophysical model, we need an astrobiological model to describe these strange systems.

In essence Vidal is claiming that these systems are not typical binary stars, but rather civilizations that have advanced well passed a Type 1 civilization on the Kardashev scale and are now actively feeding on their parent star. He calls these hypothetical civilizations starivores. And if he is right… then there are approximately 2,000 known starivores in our galaxy alone.

Perhaps, the necessary test is related to understanding the nature of the binary systems “metabolism.” Metabolism is one of the fundamental and necessary conditions for complex living systems because it allows them to draw and sustain order from the surrounding non-living chaos.

Laws Of Man And Laws Of Nature


Marcelo Gleiser philosophizes on how the laws of man and the laws of naure differ. via NPR

We humans are an unruly bunch. So much so that we need laws to keep order, to make sure we stay on track. Without our laws, society would quickly descend into chaos. The laws of man are guarantors of order, a necessary control against the inherent greediness of our species.

Nature, on the other hand, shows ordered patterns at all scales: trees branch, and so do rivers, bodies, and arteries; tides and planetary orbits are periodic, day follows night, the seasons alternate, the moon has phases. The display of order in Nature allowed for a methodic counting and organizing as a means to gain some level of control over what was otherwise distant and unapproachable, the marching patterns of a world moving in ways beyond human reach.

The laws of Nature, from the simplest to the most complex, are attempts to summarize this widespread display of order.

Power Of CERN Collider To Be Doubled, May Reveal Extra Dimensions

earthspaceAre we ready for a hint of the eleven-dimensional world? Via Reuters:

“When this refit is completed,” CERN scientist Marc Goulette says, gesturing across the gigantic Large Hadron Collider (LHC), “we shall be ready to explore an entirely new realm of physics.”

The collider is only five years old but, after swiftly finding a crucial missing link to support mankind’s main concept of the universe, is now entering a two-year revamp to double its power in the hope of breathtaking new discoveries.

Some scientists predict it might find a zoo of new particles or even catch hints that space has more than three dimensions. Oliver Buchmueller, an experimental physicist, also hopes to see proof the extra dimensions foreseen in string theory.

Could that take science beyond, into the extension of string theory that predicts the existence of parallel universes or a perpetually growing galaxy of universes, unpenetrable one from the other, that cosmologists call the Multiverse?

An Alternate Universe Will Eventually Annihilate Ours, Higgs Boson Discovery Reveals

Great, we spent all that time and money so we could find out this terrible news. Via io9:

Remember that Higgs-like particle that scientists finally managed to pin down last year at the Large Hadron Collider? According to Joseph Lykken, a theoretical physicist at the Fermi National Accelerator Laboratory, the mass of the Higgs boson indicates that “the universe we live in is inherently unstable, and at some it’s all going to get wiped out.”

After last year’s Higgs discovery, he performed a calculation that indicated the potential for a quantum fluctuation — an event that would create a lower-energy state bubble that expands at the speed of light and “sweep everything before it.” He predicts that it won’t happen for many tens of billions of years.

A little bubble of what you might think of as an ‘alternative’ universe will appear somewhere and then it will expand out and destroy us,” Lykken said.

Strange Cases Of Slippage Through Time

Mysterious Universe ponders times slips — cases in which people temporarily experience the future or past, or briefly interact with people or objects from a different era:

Physicists like Albert Einstein, Michio Kaku and Stephen Hawking have all said time travel is theoretically possible; our science just can’t achieve it. But what if nature can?

Time slips have been reported throughout history. English women vacationing in France in 1901 claimed they stepped into the French Revolution, and two English couples traveling in Spain in the 1970s stayed at an oddly archaic hotel that was simply gone on their return journey. RAF pilot Sir Victor Goddard encountered airplanes in 1935 that didn’t exist until 1939, and a 100-year-old Swiss watch found in a Chinese Ming dynasty tomb. People may slip like this all the time.

During the Aurora Borealis of 2004, visible in North America as far south as the lower Midwest, Jake, 15, stood outside his parents home in the Lake of the Ozarks, Missouri, around 10 p.m.
