Why are blazars so full of energy?
Because of its accretion disk
When a black hole approaches a star, it begins to gather material from the star's accretion disk, which is a slow-moving orbit around the black hole.
The temperature of the gas in a blazar's accretion disc rises as it approaches the black hole, creating plasma that erupts from the hole and shoots out a high-energy photon beam, creating the universe's most brilliant object.

Blazars are a particular kind of active galactic nucleus (AGN) that have a supermassive black hole at their center. Blazars emit intense amounts of energy because of processes that occur around the black hole, such as matter being accreted onto it and radiation and particle jets being released along its rotational axis. The jets are thought to be produced by charged particles interacting with magnetic fields close to the black hole, which releases high-energy radiation across the electromagnetic spectrum.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.

- During the late stages of a star's life, what causes the star to expand into a red giant/supergiant, then explode into a nebula or supernova?
- What would happen if a supernova exploded in space? What would it do to us?
- What are the characteristics of a red giant star?
- What would happen if someone entered a black hole?
- Suppose we observe a Cepheid variable in a distant galaxy that brightens and dims with a regular period of about 10 days. What can we learn from this observation?
