Announced a team of physicists in Massachusetts Institute of Technology Successful efforts to create sensors that may detect dark matter in the universe.

Scientists are puzzled when they mix theories PhysicsTogether, they conclude that the vast majority of the universe is made up of something we haven’t figured out how to observe or measure. This missing “thing” is called “dark matter”. This matter, if it exists, belongs to the quantum world, and it is very difficult to measure it, because the quantum world does not obey the laws of classical physics.

To illustrate the difficulty of measuring things in the quantum world, hit the site The Next Web For example, the technician throws a coin and then takes a picture of it while it is still in the air. There is no way to determine if it will land on the face or the writing.

In the world of classical physics, it is enough to wait for the coin to reach the ground to measure the result, but in the quantum world the coin will reset itself, and the image will not be able to determine which face it landed on.

To solve this problem, the team of scientists explained in a statement: “We used a system of lasers to trap the atoms, then sent out a blue entangled light, which forced the atoms to oscillate in a coherent state. We let the entangled atoms evolve forward over time, and then exposed them to a small magnetic field, which It led to a small quantitative change and a small change in the collective oscillations of the atoms.”

It would be impossible to detect such a shift using current measurement tools. Instead, the team applied time inversion to boost this quantum signal. To do this, they sent out another red laser that stimulated the atoms to untangle, as if they were evolving back in time.

To simplify what the scientists did, the reader can imagine that the researchers threw two coins into the air at the same time, and forced them to do exactly the same thing.

And the scientists discovered how to force the atoms to vibrate with enough force to study. The ability to detect this level of turbulence may allow us to “measure” hidden gravitational fields. This means that these techniques might lead to a complete detector of dark matter.
