Study Notes
Universe Timeline and the James Webb Telescope
- The universe's age is approximately 14 billion years.
- This concept of deep time is difficult to grasp, as it's outside our common human experience.
- Scientific understanding of the universe's age is relatively recent, developing only in the last 150 years.
- Human perception of time intervals is different from cosmic time scales.
- Time scales vary significantly between different organisms, like humans and dogs. A dog's day is equivalent to roughly seven human days.
- The James Webb Telescope is used to map the universe.
- The Gridiron timeline of the universe is one method for mapping cosmic history.
Measuring Deep Time
- Measuring time in the vastness of the universe presents unique challenges, especially with numbers as large as 14 billion years.
- Deep time concepts, such as the universe's age, are difficult to visualize due to their scale.
- Different life forms experience time differently.
