Transcript

The universe can be defined as anything that is, was or will ever be. So far as we know, it encompasses everything, and through that as a whole remains the most mysterious phenomenon we can ever know. It may even be that we are destined to never have a complete understanding of it, it’s simply too hard, and the experiments needed to glean more info... Read More

Questions & Answers

Q: What evidence supports the theory of the big bang?

The discovery of the cosmic microwave background radiation and the expansion of the universe provide strong evidence for the big bang theory.

Q: What is the significance of inflation in the early universe?

Inflation explains the uniform temperature of the cosmic microwave background radiation and suggests that the universe expanded at a faster rate during its early stages.

Q: How did the formation of matter occur in the early universe?

The formation of matter began with the synthesis of protons and neutrons, followed by the creation of hydrogen and other elements through the actions of stars.

Q: Are there other epochs in the universe's history where life could have existed?

There is a possibility of earlier habitable epochs, but any evidence of life during these periods is unlikely to have survived.

Q: Why is there a lack of evidence for alien civilizations despite the age and availability of planets?

The Fermi Paradox suggests that there may be factors preventing the detection or communication with alien civilizations, leading to the mystery of where they are.

Q: What is the eventual fate of the universe?

The universe is predicted to continue expanding and cooling, leading to the eventual extinction of stars and the creation of a cold, dark universe.

Q: Will the proton, a stable particle, decay in the future?

Scientists are uncertain about the stability of the proton and whether it may decay into other subatomic particles over extremely long periods of time.

Q: What are iron stars and what is their potential fate?

Iron stars may form in the very distant future and could eventually collapse into black holes, which would then undergo evaporation through Hawking Radiation.
