Physicists and astronomers study the ways in which various forms of matter and energy interact. Theoretical physicists and astronomers may study the nature of time or the origin of the universe. Some physicists design and perform experiments with sophisticated equipment such as particle accelerators, electron microscopes, and lasers.
The Universe is massive and incredibly old, older than everything contained within.
Sun like Star Kronos shows signs of having ingested 15 earth masses worth of Rocky planets, promoting astronomers to name it after the Titan, who ate his children
In astronomy, the geocentric model (also known as geocentrism, or the Ptolemaic system) is a superseded description of the universe with Earth at the centre. Under the geocentric model, the Sun, Moon, stars, and planets all circled Earth.
The Big Bang theory predicts that the early universe was a very hot place and that as it expands, the gas within it cools. Thus the universe should be filled with radiation that is literally the remnant heat left over from the Big Bang, called the “cosmic microwave background”
Stars. Universe has confounded mankind since ancient times. Early man would look up at the night sky and try to decipher the various shapes and figures created by groups of stars clustered together.
Every human has always wondered what lies beneath and beyond the sky. One always tends to try and put meaning to the universe that lies around him. And thus, astronomy came into being.
