Endless Facts, One Snippet at a Time
What Is Astrophysics? The Physics of the Universe
- Astrophysics blends astronomy and physics to explain how the universe works, from stars to galaxies.
- It seeks to answer big questions: how did the universe begin, and how will it end?
- Astrophysicists study light across the spectrum—radio waves to gamma rays—to unlock cosmic secrets.
- Gravity, relativity, and quantum mechanics are core tools in astrophysics research.
- Black holes, neutron stars, and supernovae are extreme laboratories of physics in space.
- Observatories like Hubble and the James Webb Space Telescope are astrophysics’ eyes on the cosmos.
- The field explores dark matter and dark energy, which make up 95% of the universe.
- Astrophysics isn’t just about space—it drives technology like GPS, imaging, and data analysis.
- By studying cosmic microwave background radiation, astrophysicists trace the universe’s earliest moments.
- At its heart, astrophysics turns the night sky into a grand physics experiment.
