A new theory suggests that a mirror universe existed before the Big Bang

Since the 1950s, scientists have discovered that certain phenomena have the ability to violate some established symmetries of the universe. This is how it has now been proposed that our universe could be the reflected image of a universe of antimatter that extends backward in time before the Big Bang.

This has been suggested by a group of scientists from Canada. They have designed a cosmological model that raises the existence of an “anti-universe” that, like ours, has a fundamental rule of physics called “CPT symmetry”.

A fairly similar study was reported 3 years ago and suggested the existence of a mirror universe where time could be moved upside down.

What is the “science” here?

The phenomena that we mentioned in the first paragraph and that could violate some established symmetries of the universe are called parity (P), which is the idea that if you change all your spatial coordinates (up, down, inside, outside, right), physics will continue to behave in the same way. Another is called charge (C), which states that the change of matter to antimatter should lead to the same physics. But that is not always the case. At first, many of these violations were resolved using the combined CP symmetry, but then the researchers found violations in this as well, so they added time (T) to the equation. The principle says that something may be able to break one (or two) of the symmetries of physics, but nothing should be able to break the combined CPT symmetry.

Unlike the previous study, this new research uses this approach for the entire universe. They argue that the universe does not violate the CPT since our universe dominated by matter, expanding in a certain direction in the time since the Big Bang, is the mirror image of a universe dominated by antimatter that existed before the Big Bang.

This theory has some interesting advantages. It does not require us to build new physics to explain several complicated events in the evolution of the universe, such as ” Cosmic Inflation,” the extremely rapid expansion of the universe in the fraction of seconds after the Big Bang. It also presents a possible candidate for dark matter, since this configuration would produce an excess of hypothetical massive particles known as sterile neutrinos.

However, it is far from being a perfect theory. It does not explain, for example, the fluctuations of temperature in the cosmic microwave background: the universe must be full of radiation, which is the remnant of heat that remains of the Big Bang after the cooling of the gas, which has been a cornerstone of the cosmological models since its discovery.

Now, the team is working to solve these problems; and if they do, they may be able to respond if there is a mirror universe populated by “evil versions” of ourselves.

The scientific study has been published in  Physical Review Letters.

Ecto-1 Returns in Teaser for Secret Ghostbusters Movie

Trailer teases the return of the Ghostbusters with a malfunctioning proton pack and a rusting Ecto-1.

A new Ghostbusters is coming in 2020! It was announced this week with the arrival of this short but effective teaser trailer. It’s an eerie night and spine-tingling music from the original Ghostbusters score is playing as the camera moves past a fence dripping with ectoplasm into an creepy barn where we hear the sound of proton pack that won’t start. And then the wind blows up a tarp to reveal a rusting Ecto-1.

The new film is being directed and co-written by Jason Reitman, the son of Ivan Reitman who directed the original Ghostbusters.

“I’ve always thought of myself as the first Ghostbusters fan, when I was a 6-year-old visiting the set. I wanted to make a movie for all the other fans,” Reitman told Entertainment Weekly. “This is the next chapter in the original franchise. It is not a reboot. What happened in the ’80s happened in the ’80s, and this is set in the present day.”

For those of us who grew up in the 80s, the 1984 Ghostbusters film was probably one of our earliest introductions to the occult, inspiring a lifetime of obsession. Sure, I was disappointed when I learned Tobin’s Spirit Guide wasn’t real, but my hope was renewed when I discovered real occult texts. And of course Ecto-1, a 1959 Cadillac built by the Miller-Meteor company, kick-started a love for hearses.

Do you believe in UFOs, astral projections, mental telepathy, ESP, clairvoyance, spirit photography, telekinetic movement, full trance mediums, the Loch Ness monster and the theory of Atlantis?

I probably had not even heard of these things before Ghostbusters.

The new Ghostbusters is set for a 2020 release.

A New Class of Drugs Could Make Safer Sleeping Pills

ZZZ

If your house caught fire in the middle of the night, you’d want to wake up to deal with that emergency, right?

In a new prescription sleeping pill study published this week in Frontiers in Behavioral Neuroscience, half of the study participants slept through a fire alarm as loud as someone vacuuming next to their bed. Researchers from Kagoshima University, Japan estimated that millions of people taking prescription sleeping pills like Ambien and Halcion would sleep through a fire alarm. They propose that a new class of hypnotic drug might be used as an alternative which would function like a sleeping pill while still allowing the brain to wake up during an emergency.

DORA The Hypnotic Drug

The most widely prescribed type of sleeping pills, benzodiazepines, are really effective at getting the brain into “sleep mode”. Unfortunately, they act as a sort of blanket, suppressing areas of the brain that they don’t need to. That includes the area of the brain that decides which external information, such as noises in the night, to pay attention to.

Over the past decade scientists have been developing a new class of hypnotic drugs called dual orexin receptor antagonists (DORAs). DORAs more selectively target the brain’s sleep/wake pathways making them a safer alternative to benzodiazepines while also leaving the user with a reduced hangover-like affect these drugs can cause.

Wake-up Call

When tested in lab mice, those that had been given the benzodiazepine triazolam were slower to rouse than those given DORA-22 when presented with the sounds of a fox, a serious threat to a mouse. Better still, once the danger had passed the mice given DORA-22 fell back asleep as fast as the mice that had been given a sleeping pill, and significantly faster than mice that hadn’t been given anything at all.

More human testing is needed in order to show DORAs have potential applications as sleep aids. Since 2014, a DORA called surovexant has gained regulatory approval in Japan, the USA and Australia. High costs and limited clinical testing of surovexant have stymied its use but new types of DORAs currently in development could some day offer better results at a lower cost.

Creepy AI can now create ‘100 per cent lifelike’ human faces from scratch

Can you tell who is real and who is not? Artificial Intelligence is now able to create lifelike human faces from scratch.

Researchers at NVIDIA have been working on creating realistic looking human faces from only a few source photos for years.

For many people it’s difficult to tell the difference between one of the
faces generated below and an actual human face, can you spot which is
which?

The source image – the top row – are the only legitimate photographs of real people, the rest have been computer generated. The programme uses various traits from real people to create new fake people

The team at NVIDIA, released a paper on the subject, and explained they used Generative Adversarial Networks (GAN), to customise the realistic looking faces.

The fake faces can be easily customised by using a method known as ‘style transfer’ which blends the characteristics of one image with another.

The generator thinks of the image as a collection of three styles, known as coarse styles (pose, hair, face shape), middle styles (facial features
and eyes) and fine styles (colour scheme).

Animals, such as cats, and objects such as a bedroom can also be generated, using the same method.

The researchers created a grid to show the extent to which they could alter people’s facial characteristics using only one source image.

One of the most fascinating aspects of this is GAN has only be around for four years.
