The lifespan of the universe is expected to be incredibly long. Current scientific theories suggest it could last trillions of years or even longer before it reaches a state called the heat death. In this scenario, the universe will have expanded so much that stars burn out, and galaxies drift apart, leading to a cold, dark, and inert cosmos.

FAQs & Answers

  1. What is the heat death of the universe? The heat death of the universe refers to a theoretical scenario where the universe reaches a state of maximum entropy, resulting in a cold, dark cosmos.
  2. How do scientists predict the lifespan of the universe? Scientists use models based on the laws of physics, cosmological observations, and theories about dark energy to estimate the universe's lifespan.
  3. Is the universe expanding? Yes, current observations indicate that the universe is expanding, which contributes to our understanding of its future and eventual fate.
