Scientists believe the "first event" in the Universe was the Big Bang. The Big Bang Theory attempts to explain how the universe was originally created.
The creation of the universe.
God said "Let there be Light" and the universe magically appeared out of nowhere.
This Answer.
Scientists estimate that the universe began forming around 13.8 billion years ago during an event known as the Big Bang. This marks the beginning of the expansion of space and the creation of all matter and energy in the universe.
Scientists refer to the event that started the universe as the Big Bang. This is a cosmological model that suggests the universe began as a very hot, dense state and has been expanding and cooling ever since.
The event that marks the beginning of the universe is the Big Bang. This was a cosmic event that occurred about 13.8 billion years ago, creating the universe as we know it today. The Big Bang theory is widely accepted by scientists as the most plausible explanation for the origin of the universe.
The Big Bang.
The first cause of the universe is often posited as a fundamental entity or event that initiated existence, commonly referred to as the "Big Bang." This singularity is theorized to have contained all the energy and matter of the universe, which expanded rapidly, leading to the cosmos as we know it. Philosophically, some argue for a prime mover or an uncaused cause, suggesting that there must be something outside of time and space that initiated the universe. Ultimately, the nature of this first cause remains a topic of debate in both science and philosophy.

Theoretically, the universe is infinite. It has no definable edge, or event horizon. Consider the space into which the expanding universe is expanding into.
The Big Bang refers to the event that created the universe. It is not expected to happen again as the universe is already expanding and evolving from that initial event. However, there are theories like the Big Crunch or Big Rip which describe possible future scenarios for the universe.
Yes, the heat death of the universe is considered an inevitable event according to current scientific understanding. This theory suggests that over an extremely long period of time, all energy in the universe will be evenly distributed, resulting in a state of maximum entropy where no more work can be done.
