Theories of the Universe

This states that the universe had a beginning and possibly an end. It states that the universe originated from a singularity, an infinitely dense point. All matter and energy was found in that singularity.

• Big Bang Theory

• Steady state Theory

• Multiverse Theory

• Cosmic Inflation Theory

This states that the universe has no beginning and no end. It states that the universe expanded but did not change density; matter was inserted into the universe as it expanded, thus maintaining a constant density.

• Steady State Theory

• Big Bang Theory

• Multiverse Theory

• Chaotic Inflation Theory

It states that the universe expanded and the universe experienced a period of exponential inflation. This solves the horizon and  flatness problems of the Big Bang Theory.

• Cosmic Inflation Theory

• None of the above

• Steady State Theory

• Multiverse Theory

It states that there may be multiple or even an infinite number of universes (including the universe we consistently experience) that together comprise everything that exists: the entirety of space, time, matter, and energy as well as the physical laws and constants that describe them.

• Multiverse Theory

• Steady State Theory

• Big Bang Theory

• Chaotic Inflation Theory

It states that different universes form from different areas/regions of a mother universe. Some of these universes expanded through inflation while others did not.

• Chaotic Inflation Theory

• Big Bang Theory

• Multiverse Theory

• Steady State Theory

Matter was not present at the beginning of time, there was only pure energy compressed in a single point called singularity

• Big Bang Theory

• Oscillating Universe

• Steady State Theory

10. It may be an infinity of universes, all with their own laws of physics, their own collections of stars and galaxies (if stars and galaxies can exist in those universes), and maybe even their own intelligent civilizations.

• A. multiverse

• B. oscillating universe

• C. static universe

• D. atomic universe
