More Than One Reality Exists Simultaneously (in Quantum Physics)   
https://amp.livescience.com/65029-dueling-reality-photons.html

Can two versions of reality exist at the same time? Physicists say they can — at the quantum level, that is

Researchers recently conducted experiments to answer a decades-old theoretical physics question about dueling realities. This tricky thought experiment proposed that two individuals observing the same photon could arrive at different conclusions about that photon's state — and yet both of their observations would be correct.

For the first time, scientists have replicated conditions described in the thought experiment. Their results, published Feb. 13 in the preprint journal arXiv, confirmed that even when observers described different states in the same photon, the two conflicting realities could both be true.

... if measurements themselves aren't absolutes — as these new findings suggest — that challenges the very meaning of quantum mechanics.

"It seems that, in contrast to classical physics, measurement results cannot be considered absolute truth but must be understood relative to the observer who performed the measurement," Ringbauer said.

New Controversial Theory: Past, Present, Future Exist Simultaneously 
https://bigthink.com/surprising-science/a-controversial-theory-claims-present-past-and-future-exist-at-the-same-time

Our experience of time may be blinding us to its true nature, say scientists. 

- Time may not be passing at all, says the Block Universe Theory.
- Time travel may be possible.
- Your perception of time is likely relative to you and limited.




The block universe theory says that our universe may be looked at as a giant four-dimensional block of spacetime, containing all the things that ever happen, explained Dr. Kristie Miller, the joint director for the Centre for Time at the University of Sydney.

In the block universe, there is no "now" or present. All moments that exist are just relative to each other within the three spacial dimensions and one time dimension. Your sense of the present is just reflecting where in the block universe you are at that instance. The "past" is just a slice of the universe at an earlier location while the "future" is at a later location.

Quantum Machine Appears to Defy Universe’s Push for Disorder     
https://www.quantamagazine.org/quantum-scarring-appears-to-defy-universes-push-for-disorder-20190320/

One of the first quantum simulators has produced a puzzling phenomenon: a row of atoms that repeatedly pops back into place. Physicists have been racing to explain what might be going on..

... Physicists have dubbed this bizarre behavior “quantum many-body scarring.” As if scarred, the atoms seem to bear an imprint of the past that draws them back to their original configuration over and over again.

Researchers Develop Way to Control Speed of Light, Send it Backward
https://phys.org/news/2019-04-researchers-develop-way-to-control.html



University of Central Florida researchers have developed a way to control the speed of light. Not only can they speed up a pulse of light and slow it down, they can also make it travel backward.

The results were published recently in the journal Nature Communications.

Previous attempts at controlling the speed of light have included passing light through various materials to adjust its speed. The new technique, however, allows the speed to be adjusted for the first time in the open, without using any pass-through material to speed it up or slow it down.

"This is the first clear demonstration of controlling the speed of a pulse light in free space," said study co-author Ayman Abouraddy, a professor in UCF's College of Optics and Photonics. "And it opens up doors for many applications, an optical buffer being just one of them, but most importantly it's done in a simple way, that's repeatable and reliable."

Abouraddy and study co-author Esat Kondakci demonstrated they could speed a pulse of light up to 30 times the speed of light, slow it down to half the speed of light, and also make the pulse travel backward.

The researchers were able to develop the technique by using a special device known as a spatial light modulator to mix the space and time properties of light, thereby allowing them to control the velocity of the pulse of light. The mixing of the two properties was key to the technique's success.
...

Open Source: H. Esat Kondakci, Ayman F. Abouraddy, Optical space-time wave packets having arbitrary group velocities in free space, Nature Communications volume 10, Article number: 929 (2019)

Abstract:
Controlling the group velocity of an optical pulse typically requires traversing a material or structure whose dispersion is judiciously crafted. Alternatively, the group velocity can be modified in free space by spatially structuring the beam profile, but the realizable deviation from the speed of light in vacuum is small. Here we demonstrate precise and versatile control over the group velocity of a propagation-invariant optical wave packet in free space through sculpting its spatio-temporal spectrum. By jointly modulating the spatial and temporal degrees of freedom, arbitrary group velocities are unambiguously observed in free space above or below the speed of light in vacuum, whether in the forward direction propagating away from the source or even traveling backwards towards it.

Future 'Human Brain/Cloud Interface' Will Give People Instant Access to Vast Knowledge via Thought Alone
https://medicalxpress.com/news/2019-04-future-human-braincloud-interface-people.html

Writing in Frontiers in Neuroscience, an international collaboration led by researchers at UC Berkeley and the US Institute for Molecular Manufacturing predicts that exponential progress in nanotechnology, nanomedicine, AI, and computation will lead this century to the development of a "Human Brain/Cloud Interface" (B/CI), that connects brain cells to vast cloud-computing networks in real time.

This cortex in the cloud would allow "Matrix"-style downloading of information to the brain, the group claims.


I Know Kung Fu! ... Show Me.

"A human B/CI system mediated by neuralnanorobotics could empower individuals with instantaneous access to all cumulative human knowledge available in the cloud, while significantly improving human learning capacities and intelligence," says lead author Dr. Nuno Martins.

B/CI technology might also allow us to create a future "global superbrain" that would connect networks of individual human brains and AIs to enable collective thought.

... an experimental human 'BrainNet' system has already been tested, enabling thought-driven information exchange via the cloud between individual brains,"

'The Matrix' hit theaters 20 years ago. Many scientists and philosophers still think we're living in a simulation.
https://amp.businessinsider.com/the-matrix-do-we-live-in-a-simulation-2019-4

In 2001, Nick Bostrom, a philosopher at the University of Oxford, circulated the first draft of a paper suggesting that a highly advanced supercomputer - with a mass on the order of a planet - would be capable of running a simulation on a humanity-size scale. (Bostrum told Vulture that he hadn't seen "The Matrix" before publishing the paper.)

Bostrom said this computer would be capable of doing 10^42 calculations per second, and it could simulate the entire history of humankind (including all our thoughts, feelings, and memories) by using less than one-millionth of its processing power for just one second.

By this logic, all of humanity and our entire physical universe are just blips of data stored in the hard drive of a massive supercomputer.

He concluded: " We are almost certainly characters living in a computer simulation."



There is no spoon!

... Many scientists argue, however, that we'll never be able to figure out whether or not we're living in a simulation.

Marcelo Gleiser, a physicist and philosopher at Dartmouth College, told New Scientist that trying to address Bostrum's question based on our current knowledge and technological capabilities is pretty hopeless. That's because if we were really living in a simulation, scientists wouldn't have any idea about the laws of physics in the "real world" outside. They also wouldn't know what kinds of computations would be possible outside the bounds of our simulation, Gleiser said.

... So everything that we think we know about what's possible in terms of computing power or the laws of physics could just be another aspect of the simulation.

... "If we're indeed a simulation, then that would be a logical possibility, that what we're measuring aren't really the laws of nature, they're some sort of attempt at some sort of artificial law that the simulators have come up with,"

Nah. No Simulation. Supposing a simulation is a cop out, like religion. The only way the world is a simulation is that the human brain takes what it perceives of the universe runs it through a computer and the product of that calculation is what we call consciousness. We each have our own simulation. The simulation starts when the first few cells differentiate into neurons and ends when the neurons run out of power.

If time passes and there is no one around to experience it, does time passes?

Morpheus: What is real? How do you define real? If you're talking about what you can feel, what you can smell, what you can taste and see, then real is simply electrical signals interpreted by your brain. 

... Or maybe it's all a dream?

What we can feel, smell, taste, see, hear, our perception of acceleration and time is our common reality. We perceive signals and the network of neurons in our brains process them. The output is consciousness.

 No simulation outside. No dream state. None of that is needed.

All wrong oren, it is merely an optical illusion. You actually don't need the left or right images to see her rotate in different directions, but they are helpful for those who can't see a reversal (using only the center image).

Experimental Device Generates Electricity From the Coldness of the Universe
https://phys.org/news/2019-05-experimental-device-electricity-coldness-universe.html



An international team of scientists has demonstrated for the first time that it is possible to generate a measurable amount of electricity in a diode directly from the coldness of the universe. The infrared semiconductor device faces the sky and uses the temperature difference between Earth and space to produce the electricity.

"The vastness of the universe is a thermodynamic resource," said Shanhui Fan, an author on the paper. "In terms of optoelectronic physics, there is really this very beautiful symmetry between harvesting incoming radiation and harvesting outgoing radiation."

In contrast to leveraging incoming energy as a normal solar cell would, the negative illumination effect allows electrical energy to be harvested as heat leaves a surface. Today's technology, though, does not capture energy over these negative temperature differences as efficiently.
