Explanation:
the big bang theory describes how the universe began in a hot, dense state that has since expanded and cooled over the past 13.3 to 13.8 billion years, with the calculated age depending on the particular observations and scientific model of the universe that are used.
Alpha particles, also called alpha rays or alpha radiation, consist of two protons and two neutrons bound together into a particle identical to a helium-4 nucleus. They are generally produced in the process of alpha decay, but may also be produced in other ways.
A gamma ray is electromagnetic radiation of the shortest wavelength and highest energy. Gamma-ray radiation has wavelengths generally smaller than a few tenths of an angstrom (10−10 meter), and gamma-ray photons have energies greater than tens of thousands of electron volts.
