This image from the Hubble telescope is a breathtaking affirmation of Einstein’s theory of general relativity. Gravitational lensing is what gives the middle of the image a slightly  warped look; the enormous mass (and therefore incredible gravity) of the  galaxy cluster in between the telescope and more distant galaxies  behind it warps the fabric of spacetime to distort and magnify the light coming from distant objects. The four identical white lights near the center of the image are actually all the same quasar, repeated in a “gravitational mirage” by the lensing effect.
