From the big bang theory, after cooling the debris, allowed the formation of the following
galben [10]

Debris (Hydrogen and helium) from the big bang gravitationally clumped together, and frequently these clumps got big enough to start fusion in their centers and form stars.

What is big bang theory?

The Big Bang theory explains how the cosmos expanded from a highly dense and hot starting condition. The evolution of the observable cosmos from the earliest known times up to its later large-scale shape is explained by this prevalent cosmological model. A wide range of observable phenomena, such as the quantity of light elements, the cosmic microwave background (CMB) radiation, and large-scale structure, are all thoroughly explained by the model.

Eventually, the large gaseous balls fuse hydrogen into heavier elements, which causes them to become stars. The periodic table's iron is created when stars combine light elements to create heavier ones.

The remaining elements of the periodic table are created as a result of the stars exploding, producing white dwarfs that explode, or forming neutron stars that collide and explode. The remaining hydrogen gas is now "contaminated" by this other material, and some of it forms an accretion disk in which planets form when it compresses under gravity.

Why is it painful when a bee stings you.​
stellarik [79]
It’s painful because when they sing, a chemical is released called melting into the victim. That venom quickly triggers the receptors of pain, and thus causing the burning sensation. Another reason is because the stinger on a bee is barbed and when it sinks into the skin, it detaches from the bee and stays into the skin of the victim.
