a. According to the Big Bang theory, our universe began as a singularity which rapidly expanded around 13.8 billion years ago.

b. Some planets have moons and satellites because they may have captured them as they traveled through space, while others may not have been able to capture any due to various reasons such as gravitational interactions with other celestial bodies.

c. The foundation of the Big Bang theory was provided by the observations made by astronomers such as Edwin Hubble, who discovered the expansion of the universe through the redshift of galaxies.

d. Nowadays, the universe is still expanding, with galaxies moving away from each other at an increasing rate due to the force of dark energy. This expansion is leading to the universe becoming larger, colder, and darker over time.
