Supercooling refers to the process where a substance is cooled below its freezing point without solidifying, but it is not officially recognized as a distinct state of matter. At extremely low temperatures, such as below 4 Kelvin, matter can enter states like Bose-Einstein condensates or superfluids. Superfluidity is a phenomenon observed in certain liquids at very low temperatures, where they flow without viscosity. The discussion highlights the importance of precise terminology when discussing states of matter and encourages proper communication. Understanding these concepts is essential for grasping advanced physics topics.

is there a state of matter called the supercool state or something..if yes,can someone please elaborate?..if no,can someone please reply about the states of matter..?
when stuff gets really cold like below 4 Kelvin , it can become an Einstein-Bose condensate

Yes, I've seen "superfluid" described as another state of matter.

do u mean..like..when gas is exposed to -279 deg celcius..it directly changes into liquid or a superfluid as u may call it..??

Please type words properly; you are not "texting".
Try http://en.wikipedia.org/wiki/Superfluid" . Notice in the first sentence it links to "phases of matter", which is what we are talking about as "states".
Do we even know? My understanding of dark energy is that particles come into existence, exert and outward force, then vanish. My problem with that is how, of course, then how does dark energy know to push everything in the same direction? The pressure exerted would be in all directions, even if the space was moving so why isn't stuff pushed all over the sky?
Thanks - rev
