Blazars Are A Thing

The video uses a roll of toilet paper to illustrate how perspective affects naming in astronomy. It explains that quasars and blazars are the same astronomical objects viewed from different angles. Quasars are seen at an angle, while blazars are viewed head-on, causing them to appear brighter due to Doppler boosting. The video concludes that while the distinction between quasars and blazars is debated, they are essentially the same phenomena observed differently.
