Have you ever wondered you are going to travel to Mars? As a common man, it is near too impossible for thinking about the situation but NASA had started a new program called Send Your Name To Mars. Under this program, NASA has started an online form filling. Link to this program will be given. To send your name to mars you have to just go through the link which I will provide you. If you do not know how to fill the form, fill your form with the science behind science- Here is the link "Send Your Name to Mars: Future Mission" Fill the form fast and make your friends jealous of the boarding pass. But don't make them that jealous share th e link to your friends and family as fast as possible. The link is given here for how to fill form and link for the form:- Share the link fast because forms are filling fast:- https://truesciencebehindscience.blogspot.com/2021/02/send-your-name-to-mars-mars-2020.html First, you have to go through the link given below: The link will direct...
Have you ever thought about a matter which is frictionless😮? Today you will know about such a state that is almost impossible to exist. But it can exist under certain impossible conditions. So, let's dip into the fluid which is frictionless with Science behind Science-
Superfluid, the literal meaning for this word is a type of matter which is very good in deforming and very unstable. According to physics Superfluid is a substance that has the characteristics of superfluidity. In other words, a fluid that has zero viscosity and no entropy, therefore, flows without losing any of the kinetic energy. If Superfluid is stirred it forms an infinite vortex that means a never-ending vortex.

In 1937, Pyotr Kapitsa in Moscow discovered an amazing material today called superfluid. He noted many of its properties and published an article in 1938. Later he was awarded a Nobel prize in 1978 for his great achievements in low-temperature physics.

Helium-4 an isotope of helium. Liquid Helium at the temperature of 2.17 Kelvin starts showing the properties of Superfluid. When this He-4 is cooled to 2.17 kelvin. The gas He-4 liquefies and turns to a liquid, an abnormal liquid. Its properties get changed now it has those properties which can't be possessed by a normal fluid. He-4 becomes a fluid that has zero viscosity and has no entropy. According to a physicist if this fluid is being stirred it will form an indefinite vortex which can continue to million, billion years. Because the friction between the molecule is diminished to zero. Hence the kinetic energy of the particle never decreases and remains constant forever.
At the temperature of 2.17 kelvin, the thermal conductivity of superfluid increases tremendously to million times from the normal temperature. In other words, the temperature and electricity from this could pass very easily. Which is very high from the thermal conductivity of copper or silver. The property of thermal conductivity also provides it one more super ability in which thermal conductivity does not allow the fluid to boil at its boiling point.
In one experiment, Superfluid Helium was filled in a beaker. Then the beaker was put at a temperature of 2.17 kelvin. The result was astonishing, superfluid came out of the beaker. It means superfluid pierced the gap between molecules and came out of the gap.

The kinetic energy of the material increases so much that when it is still and no force is applied then also it will come out of the vessel itself.
There are many more experiments on superfluid but all that can't be fitted in just one post. Some physicist assumes that the link to understand dark matter and dark energy can be solved with the help of the concept of superfluidity.

Scientists also assume that space-time maybe some sort of superfluid which is highly slippery and many other predictions. For today that's all thank you for all your support. Meet you next time.
