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.

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.
The first event was the wedding.
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.
