The multiverse is just a mirage

So your consciousness determines what you can perceive!

Through the senses of our body, a wealth of information enters our minds, which we process, filter through our senses over and over again, and a lot of information is lost at every step. Eventually, it turns out that our consciousness is self-sufficient. Our brains process four hundred billion bits of information per second about our environment, body, feelings, and time, but we only pay attention to two thousand bits of this. This means that we live in a world where everything we perceive is just the tip of the iceberg - we only notice what our habits allow while simply ignoring the vast mass of information left - the invisible part of the vast iceberg of countless possibilities. If the brain processes four hundred billion bits of information, and we pay attention to only two thousand of it, it means that what we experience as reality — which is our world — is just a set of information filtered out and limited by our consciousness. And our consciousness performs the filtering based on its own endowments and limitations.

If assuming that universe is a swelling bubble and outside it, more bubble universes exist, all immersed in an eternally expanding and energized sea—the multiverse. The hypothesis sprang from efforts to understand our own universe’s birth. The difference between bubble universes and their surroundings comes down to the energy of space itself. Create an algorithm to simulate the universe! One group recently coaxed vacuum bubble-like behavior out of a simple simulation. 1,000 digital arrows that could point up or down. The place where a string of mainly up arrows met a string of largely down arrows marked a bubble wall, and by flipping arrows, the researchers could make bubble walls move and collide. In certain circumstances, this model perfectly mimics the behavior of more complicated systems in nature.

If you can encode your system on a device that’s realized in nature, you don’t have to calculate it, That device is known as a quantum annealer. A limited quantum computer, it specializes in solving optimization problems by letting qubits seek out the lowest-energy configuration available—a process not unlike false vacuum decay. If programmed a string of about 200 qubits to emulate a quantum field with a higher- and a lower-energy state, analogous to a false vacuum and a true vacuum. 

 If two condensates interfere in just the right way, the group predicted, experimentalists should be able to capture direct images of bubbles forming in the condensate—ones that act similarly to the putative bubbles of the multiverse. The experiment, it contains by definition all the physics that nature wants to put in it including quantum effects and classical effects, How to steady the condensate blend against collapse from unrelated effects. I hope finally ready to set up a prototype experiment, and they hope to be blowing condensate bubbles in the next few years.

 If all goes well, they’ll answer two questions: the rate at which bubbles form, and how the inflation of one bubble changes the odds that another bubble will inflate nearby. These queries can’t even be formulated with current mathematics. 

That information will   calculate exactly how a whack from a neighboring bubble universe in the distant past might have set our cosmos quivering. One likely scar from such an encounter would be a circular cold spot in the sky, which  But other details—such as whether the collision also produces gravitational waves—depend on unknown bubble specifics.

 If the multiverse is just a mirage, physics may still benefit from the bounty of tools being developed to uncover it. To understand the multiverse is to understand the physics of space, which is everywhere.

I think so... everything you see and experience, including time, can only be a projection and an illusion No matter how extreme the idea sounds, theories about whether the Universe is an illusion or a hologram are not new. The researchers claim to have found evidence to support the hypothesis. Read more: Cosmic rays suggest that our universe can be a computer simulation The holographic universe is information that makes up what we perceive to be 3D reality and that is contained in time. Imagine that everything you see, feel and hear in three dimensions, and the perception of time actually comes from a flat two-dimensional field. “White noise” or microwaves.Using this information, the team was able to compare networks of data characteristics and quantum field theory.They found that the simplest quantum space theories could explain almost all cosmological observations of the early universe. But what if we only perceive what they want .

What does qantum  annealing mean?

In mathematical analysis, the maxima and minima of a function, known collectively as extrema, are the largest and smallest value of the function, either within a given range, or on the entire domain. 

The systems work through a process called quantum annealing. This begins by placing a system's qubits in an absolute energy minimum. From there, the hardware gently alters the configuration of the system so that its energy landscape reflects the problem that needs to be solved. If everything goes well, all the qubits will end up with the lowest possible energy in the new landscape. Viewed literally, this will end up identifying the lowest energy state of that landscape. But if the energy landscape represents something else—some other problem restructured so that it looks like an energy minimization—the final state will represent a solution to that problem.

 the machine a quantum annealer to distinguish it from the gate-based quantum computers being developed by (among others) Google, IBM, and Intel. The gate-based quantum computers can perform a broad range of computations, and it has been shown mathematically that, for some problems, the computers provide a dramatic speed-up compared to traditional computers. Right now, however, the companies making these systems are struggling to scale up the number of qubits to more than a few dozen; it's estimated that more than 1,000 qubits are needed to provide the error correction necessary to make these computers reliable.

A quantum annealer cannot solve the same range of problems, and the mathematical foundations underlying the system have not been explored as deeply. With a 5,000 qubit machine in the works, however, scaling up has proven far less problematic. And failures due to errors will often produce a good-but-not-optimal result on a quantum annealer, unlike a gate-based quantum computer.

That's how it's supposed to work, at least. Energy landscapes tend to look like a collection of peaks and valleys, and there's a chance that the system will get stuck in a valley that's not the absolute minimum. While the system should be able to take advantage of quantum effects to tunnel out of these valleys, the process isn't deterministic; sometimes, it will simply remain stuck. In some cases, this won't matter much, as a good minimum can be nearly as valuable as the best. In cases where it does matter, the same problem can be run multiple times, with the best solution identified by its frequency.
