Answer 2

a. According to the Big Bang theory, our universe began approximately 13.8 billion years ago as a singularity—a point in space and time with infinite density and temperature. This singularity expanded rapidly, leading to the formation of the universe. As it expanded, the universe cooled and allowed the formation of matter, galaxies, stars, and eventually planets.

b. Planets have moons and satellites because of gravitational interactions. Moons are natural satellites that orbit planets. Planets with stronger gravitational forces can capture or retain moons, while those with weaker gravitational forces may not have moons. The presence or absence of moons is primarily determined by a planet's mass and proximity to other celestial bodies.

c. The foundation of the Big Bang theory was provided by several astronomers and physicists. The theory was primarily formulated based on the observations and work of Georges Lemaître, a Belgian priest and physicist, and Edwin Hubble, an American astronomer. Lemaître proposed the idea of an expanding universe in the 1920s, and Hubble's observations of galaxies moving away from each other and the discovery of the redshift of light from distant galaxies provided crucial evidence supporting the theory.

d. The current state of the universe is continually evolving. It is still expanding, as confirmed by various astronomical observations, including the redshift of light from distant galaxies. This expansion is happening at an accelerated rate, driven by dark energy, a mysterious force. Within the universe, galaxies continue to move, stars are born and die, and various cosmic processes are ongoing. The universe is dynamic, with ongoing changes and developments in its structure and contents.
