Question

anyone knows about BigBang effect in space​

Answer 1

Answer:

Deuterium atoms then joined up with each other, forming helium-4. This all-sky image of the cosmic microwave background, created by the European Space Agency's Planck satellite, shows echoes of the Big Bang left over from the dawn of the universe.

Answer 2

Explanation:

Bang became more and more "diluted" in space, causing the universe to cool. Popping open a beer bottle results in a roughly similar cooling, expanding effect: gas, once confined in the bottle, spreads into the air, and the temperature of the beer drops.
