🌌The Big Bang theory suggests that the universe began with a hot, dense phase called inflation.
🚀Before inflation, the universe underwent a rapid exponential expansion.
🌏There may be multiple universes, and our universe could be infinite in extent.
🔭The universe is currently expanding and is likely to continue expanding forever.
🔬Scientists are studying the cosmic microwave background radiation to understand the early state of the universe.
What is the Big Bang theory?
—The Big Bang theory proposes that the universe began with a hot, dense phase called inflation. It is the prevailing cosmological model for the origin of the universe.
What happened before the Big Bang?
—Before the Big Bang, the universe underwent a rapid exponential expansion. This phase is called inflation.
Are there multiple universes?
—There may be multiple universes, and our universe could be infinite in extent. Some theories suggest the existence of a multiverse.
Is the universe still expanding?
—Yes, the universe is currently expanding and is likely to continue expanding forever. This expansion is supported by observations and measurements.
How do scientists study the early state of the universe?
—Scientists study the early state of the universe through the cosmic microwave background radiation, which is the oldest light in the universe.
