Gravitational Lensing (115.0K)
Here we explore how the gravity of dark matter, in whatever form, is detected by the lensing of light passing close to it from more distant, brilliant young galaxies and quasars, a concept first suggested by Einstein and tested with great success in a total solar eclipse in 1919. But how do we know we are in fact seeing this?
In this interactive we saw how the gravity of a massive object is detected by the lensing of light passing close to it from more distant quasar. Bur what if the object being lensed is not a point-like quasar image, but an extended galaxy?
Here we explore how the gravity of dark matter, in whatever form, is detected by the lensing of light passing close to it from more distant, brilliant young galaxies and quasars, a concept first suggested by Einstein and tested with great success in a total solar eclipse in 1919. We find that the viewing angle plays a huge role in how the see the distant object here on Earth.
Here we explore how the gravity of dark matter, in whatever form, is detected by the lensing of light passing close to it from more distant compact collapsed star, just as Einstein predicted and was tested in the 1919 total solar eclipse.
