A nearby black hole just erupted for the first time in 26 years and scientists are ecstatic.
- great, here come the Chitauri.kona
- Literally on our doorstep!Ianbolton
- so if gravity is so strong that even light cant escape it, that makes gravity faster than the speed of light right?moldero
- I've never heard gravity described as having a speed.monospaced
- The strength of the gravity created by the super dense singularity is what 'captures' the light. Light particles are effected by gravity throughout the...Morning_star
- ...universe. In the case of a black hole the gravitatonal force is so great, particles of light cannot break free.Morning_star
- Gravity is the product of mass and speed. So with enough mass speed gets negatedgilgamush
- Some of my books starting falling off my shelves.face_melter
- how is gravity a product of speed?monospaced
- yeah, what gilgamush said is false.sarahfailin
- not false. for instance the speed of the earths rotation creates centripetal forcegilgamush
- newton's second law brobrogilgamush
- It's not literally on our doorstep is it. It's the exact opposite of literally on our doorstep... lolset
- That's NOT Newton's 2nd Law, and centripetal force is NOT the same as gravity, not even a little. Earth's MASS creates gravity and inward force.monospaced
- Umm, no one knows how gravity is created...set
- correct, but we certainly know where its source is: mass :)monospaced
- Weight squared = gravity over speed of rotation. Nobody said they were the same dummy. They affect each other thoughgilgamush
- the earth's rotation doesn't affect the gravitation pull, which stays constant... please don't call me a "dummy."monospaced
- well i just explained the relationship why it does soooooogilgamush
