Big bangTheBig Bang is the expansion of the Universe from an extremely hot and dense state that started about 13.7 billion ago.
Gas is one of the four basic states of matter. A pure gas consists of individual molecules(like helium, xenon, neon, etc), diatomic molecules (like oxygen, sulphur, hydrogen, etc) or a compound molecule made of different atoms(as in CO2). A mixture of gases contains variety of gaseous molecules like that of air. Read More>>
Gravitational Force is an attraction between two bodies by the virtue of their mass. The force of attraction between two point masses is , where m1 and m2 are the masses of the particles and r is the distance between them. G is a universal constant having the value 6.67 × 10-11 Nm2kg-2. Read More>>

A small, soft space rock smacked into Costa Rica on April 23, 2019. And it may have carried building blocks for life. The washing machine-sized clay fireball broke up before landing, . Locals found shards scattered between two villages, La Palmera and Aguas Zarcas. And while meteorites turn up all over Earth, these shards were special; the asteroid that spawned them was a soft remnant of the early solar system, made from the dust from the spinning nebula that would ultimately form our solar system, formed in even older stars. This particular space rock contains complex carbon compounds, likely including amino acids (which join to form proteins and DNA) and perhaps other, even more complex building blocks of life.
