Creating super fluid, pushing forward will accelerate backwards

Unlike the known physical objects, when you push this liquid forward it will accelerate backwards.

Researchers in the US said they created a liquid with a negative volume in the laboratory . which is almost unreasonable. So that means, unlike the known physical objects, when you push this liquid forward it will accelerate backwards instead of moving forward .

Such an odd phenomenon can tell scientists as a valuable source of information to study some strange phenomena that occur inside black holes and neutron stars .

The question here is how can something have a negative mass, which goes against the usual scientific principles?

Hypothetically, negative volume appears in the same way as positive and negative charges in the electrode. According to theoretical research, it is reasonable, but it is fierce controversy in the scientific world even if matter with negative mass can exist without breaking physical principles.

The first material with negative mass is produced in liquid form.

Newton's law of motion is usually written in the form of formula f = ma , or force equivalent to the product of its mass and acceleration. If we rewrite it as an acceleration equal to a force divided by the mass of the object and make the mass negative then that would cause negative acceleration - try imagining sliding a glass on a table and it will repel your hand.

However, just because it seems strange to us, does not mean that it cannot and research the previous theory shows some evidence that negative mass can exist in our universe. does not violate universal theories.

Moreover, many physicists think that negative mass can be linked to some of the strange things discovered in the universe, such as dark energy, black holes and neutron stars.

To create this strange liquid, the team used lasers to cool rubidium atoms.

As a result, the researchers tried to reproduce the negative volume in the laboratory and have achieved some initial success.

Researchers from Washington State University said they had succeeded in obtaining a liquid of rubidium atoms with negative mass and suggested using this liquid to study some of the strange phenomena. happens in the deep space.

" The first problem here is to control the nature of the negative mass without any other variation occurring, " said one of the researchers, Michael Forbes.

To create exotic fluids, the team used lasers to cool rubidium atoms to a fraction above absolute zero, creating a Bose-Einstein condensate. In this state, particles move extremely slowly according to the strange principle of quantum mechanics, not classical physics - which means that they begin to behave like waves, with one position without determined.

The particles also synchronize with each other and move uniformly, forming a super fluid - a flowing substance without losing friction energy.

The team used lasers to hold the superfluid at freezing temperature, to trap it in a bowl containing less than 100 microns. While still in the container, this super liquid still follows the Bose-Einstein condensation phenomenon normally.

However, when released by a second laser by clicking atoms to move back and forth to change their spin to break down the container and allow rubidium to spill out so quickly that atoms act as if it were has negative volume.

" Once you push, it accelerates backwards, seeming rubidium collided with an invisible wall, " Forbes said.

Up to this point, researchers believe that the liquid they create is the material of negative mass. It is too early to say that this supernatant is sufficient to test some of the laboratory's sound mass suggestions, and should be tested independently and objectively by other units.
