Basically there are 4 states of matter. Solid, liquid, gas and plasma. Apart from these the Bose Einstein condensate is also considered as 5th state of matter. read more
There are also proposed very high energy states and hypothetical states where gravity itself is considered as a state of matter called gravitational singularity; may be present at the center of black holes. Glass n crystals are also considered as non classical states. read more
In physics, a state of matter is one of the distinct forms in which matter can exist. Four states of matter are observable in everyday life: solid, liquid, gas, and plasma. read more
Among non-classical states of matter, plasma is the most abundant, accounting for a large percentage of the baryonic matter in the known universe. Other non-classical states can bear strong similarities to classical ones, require specific environmental conditions, or exist primarily in theory. read more
