In This Article

• Questions about time have sparked philosophical debates, inspired scientific investigations, and fueled artistic and cultural expressions throughout history.
• The question of how time began or whether it had a specific start is still an area of active research and speculation in cosmology and theoretical physics. In the context of the universe, the scientific discussions on the start of time are closely related to the concept of the origin of the universe itself.
• The main question physicists study is whether time is a reality or an illusion. Time is commonly regarded as a fundamental concept, existing independently and not composed of or reliant on anything else.
