In the case of “weak lensing”, gravity doesn’t create the image of a distant galaxy, but it still produces a measurable useful effect. Collective light from many galaxies or other sources passing near a galaxy cluster is brightened by weak lensing, letting researchers map the mass of the lens. The “Bullet Cluster” is a case … See more According to general relativity, gravity can be described as a distortion in the structure of spacetime. Objects like planets and even light follow the straightest possible path within that structure, but the … See more When light from a distant galaxy passes by a massive galaxy or galaxy cluster closer to Earth, gravity bends the path of the light. Since the source galaxy emits light in all directions, … See more The gravity from stars obviously is far weaker than that of a galaxy cluster, but in some cases astronomers can still measure lensing from them. “Microlensing” is the effect when one star … See more sun zapper zinc stick https://bearbaygc.com
