(TMU) — Theoretical physicist Sean Carroll expressed that clues in the small-scale structure of the universe point to the existence of numerous parallel worlds.
The shocking comments were made on the Joe Rogan Experience (JRE) podcast last year. Carroll says that the fact that tiny particles like electrons and photons don’t have one set location in the universe is evidence that there are many parallel universes.
Recently, in a follow up interview with News.com.au, Carroll expanded his thoughts. “But there’s a lot more going on,” Carroll told News.com.au. “Not every world you imagine actually comes true.”
The common sense rules of physics that rule our lives everyday make sense to us but at very minuscule scales common sense breaks down altogether. At the quantum level, the empty vacuum of space is filled with tiny particles constantly popping in and out of existence.
Bell’s theorem, a fundamental construct in quantum mechanics, may prove that multiverses exist. This theorem deals with situations where particles interact with each other, become entangled, and then go their separate ways, according to New Scientist.
“There are still equations, physical rules, patterns that must be obeyed. Some possible alternate worlds can come true. But not all of them,” Carroll said.
In the past, Carroll has advanced some groundbreaking yet controversial theories on topics such as the Big Bang theory and the nature of time.
He has said that the universe didn’t start in a huge explosion as most people now believe, but instead it is an infinitely old, constantly inflating entity in which time can run both forward and backward.
For Carroll quantum physics is not something that can be broken down and explained in simpler terms.
“As far as we currently know,” he writes. “Quantum mechanics isn’t just an approximation to the truth; it is the truth.”
“Physics is stuck trying to understand the fundamentals of nature and the Big Bang,” Carroll said. “It’s time to take a step back and understand its foundations. It’s time to tackle our understanding of the quantum world.”
In 2011 physicist Brian Greene wrote a book exploring the possibility called The Hidden Reality: Parallel Universes and the Deep Laws of the Cosmos.
“You almost can’t avoid having some version of the multiverse in your studies if you push deeply enough in the mathematical descriptions of the physical universe,” Greene told NPR. “There are many of us thinking of one version of parallel universe theory or another. If it’s all a lot of nonsense, then it’s a lot of wasted effort going into this far-out idea. But if this idea is correct, it is a fantastic upheaval in our understanding.”
Even Stephen Hawking suggested that, thanks to quantum mechanics, the Big Bang supplied us with an endless number of universes, not just one.
Up until this point understanding quantum physics and its realms has been impossible, but Carroll hopes that is changing thanks to technology.
“Now we’re getting better at that,” Carroll says. “Technology has improved. Maybe things are going to change.”
Greene, Carroll, and Hawking may be right, and researchers at Oak Ridge National Laboratory in Tennessee want to find out if there are multiverses or mirror images of our own reality. The team was set to record experiments last year sending a beam of subatomic particles down a 50-foot tunnel, past a powerful magnet and into an impenetrable wall.
“If it exists, it would form a bubble of reality nestling within the fabric of space and time alongside our own familiar universe, with some particles capable of switching between the two,” lead researcher Leah Broussard told New Scientist.
Chinese Military Satellite Smashed by Russian Rocket in “Major Confirmed Orbital Collision”
In an incident that is likely illustrative of things to come, Chinese military satellite 1-02 was smashed after it appears to have collided into the debris from a disintegrating Russian rocket.
The collision, which occurred earlier this year, shows the increasing danger of space junk such as satellite parts and other miscellaneous jetsam littering the Earth’s orbit. An estimated 8,000 metric tons of space debris pose the risk of destroying functional equipment such as weather forecasting systems, telecoms and GPS systems – and even manned space travel missions – if the problem isn’t reined in.
The fate of the Chinese satellite was uncovered by Harvard astrophysicist and satellite tracker Jonathan McDowell.
The breakup of Yunhai 1-02 was initially reported by the U.S. Space Force’s 18th Space Control Squadron (18SPCS). However, it wasn’t until recently that McDowell found out what caused the breakup.
The astrophysicist soon found that it was destroyed by space junk that originated from a Russian Zenit-2 rocket that had launched a spy satellite in 1996. On Aug. 14, McDowell found a strange entry in a database on Space-Track.org: “Collided with satellite.”
“This is a new kind of comment entry — haven’t seen such a comment for any other satellites before,” McDowell tweeted.
“A quick analysis of the TLEs show that Yunhai 1-02 (44547) and [the debris object] passed within 1 km of each other (so within the uncertainty of the TLEs) at 0741 UTC Mar 18, exactly when 18SPCS reports Yunhai broke up,” he added, noting that this “looks to be the first major confirmed orbital collision in a decade.”
However, the Yunhai satellite still remains functional and is transmitting radio signals, notes Space.com.
The incident shows the growing likelihood of such collisions in the high-traffic, littered near-Earth orbital zone.
“Collisions are proportional to the square of the number of things in orbit,” McDowell explained. “That is to say, if you have 10 times as many satellites, you’re going to get 100 times as many collisions.”
He added: “So, as the traffic density goes up, collisions are going to go from being a minor constituent of the space junk problem to being the major constituent. That’s just math.”
A worst-case scenario of such collisions is known as the “Kessler Syndrome,” and describes the possibility of one collision setting in motion a chain of collisions. Such a disaster was the premise of the 2013 film “Gravity.”
One hopes that things don’t reach that point.
In the meantime, however, there have been a number of initiatives meant to tackle the growing problem of space debris, such as the ELSA-d spacecraft launched in a demonstration mission earlier this year.
Scientists Find Possible New Signs of Alien Life on Saturn’s Icy Moon
A new study suggests that Saturn moon Enceladus, which is covered in an icy crust, could be a great place for life to exist.
New evidence collected by NASA’s retired Cassini spacecraft offers tantalizing details on the chemical makeup of the water plumes erupting from Enceladus.
The heavy amount of methane – a gas associated with life on Earth – suggests that underneath the icy crust of Enceladus, there could be a huge ocean of briny water potentially teeming with life.
The new study by researchers from the University of Arizona and Paris Sciences & Lettres University also found that there was a relatively high concentration of molecules of dihydrogen and carbon dioxide.
“We wanted to know: Could Earthlike microbes that ‘eat’ the dihydrogen and produce methane explain the surprisingly large amount of methane detected by Cassini?” asked University of Arizona associate professor and lead author of the study Prof. Regis Ferriere.
Scientists have long speculated that conditions on Enceladus, with its subsurface ocean and sources of warmth, could be conducive to the development of living creatures.
However, one possible explanation for the chemical composition of water on Enceladus could be the existence of microbes on the Saturn moon.
“In other words, we can’t discard the ‘life hypothesis’ as highly improbable,” Ferriere noted. “To reject the life hypothesis, we need more data from future missions.”
Confirmation of the “life hypothesis” will likely remain elusive for the foreseeable future.
“Searching for such microbes, known as methanogens, at Enceladus’ seafloor would require extremely challenging deep-dive missions that are not in sight for several decades,” Ferriere said.
Stunning New Images Show Glowing Auroras on Mars
A new probe from the UAE to study the atmosphere of Mars has captured never-before-seen images of a night time aurora on the Red Planet.
The UAE’s Hope Mars mission was meant to study the Martian atmosphere over the course of the year across the totality of its layers. However, before its actual scientific mission began, it managed to snap the shots of the extremely brief phenomenon, reports Space.com.
In images released on Wednesday, the auroras stand out clearly as bright flashes against the pitch-black night sky.
The chance discovery – which wasn’t even a part of the probe’s formal mission – shows the exciting finds other nations’ space programs are capable of finding.
“They’re not easy to catch, and so that’s why seeing them basically right away with [Emirates Mars Mission] was kind of exciting and unexpected,” said Justin Deighan, the deputy science lead of the mission and a planetary scientist at the University of Colorado.
“It’s definitely something that was on our radar, so to speak, but just looking at our first set of nighttime data and saying, ‘Hey, wait a second — is that? — it can’t be — it is!’ — that was a lot of fun,” he added.
On Earth, auroras or “northern lights” are the result of electrons surfing across the electric field during geomagnetic storms, causing atmosphere particles to ionize and create the colorful and dazzling light shows.
On Mar, similar auroras seem unrestricted by the north and south poles and happen across the rest of the planet.
This is because the magnetic atmosphere isn’t aligned like a bar magnet, as it is on Earth.
Rather, the Martian magnetic more resembles a situation where “you took a bag of magnets and dumped them into the crust of the planet,” Deighan told the New York Times.
“And they’re all pointed different ways,” he said. “And they have different strengths.”
This results in solar wind particles firing off in different directions, causing interactions with molecules and atoms across the Red Planet’s upper atmosphere and triggering the aurora.
The Mars Hope team hopes the discovery can lead to fresh insights on how the planet’s atmosphere interacts with solar activity.
