When gravity of an extremely dense object bends space gravitational lensing is likely to happen. The simple understanding to this is when you think of putting a bowling ball into a mattress. The same way eyeglasses have lenses, it is the same way space could act as a lens. It is true that distortion would be caused by all types of objects but those very dense ones would cause enough of it that would easily result into a bend. In the long run, objects will appear closer.
It is through this kind of reasoning that gravitational lensing recently made headlines. Thereafter, Supernova was discovered by Kelly the UC Berkeley postdoctoral scholar who admits that it threw him a loop. “It was such a surprise for me”. Kelly adds. A special issue of Science which marks the 100th anniversary of Albert Einstein’s General Theory of Relativity describes how the discovery appeared. The discovery whose research has been going on for 50 years has been termed as the most amazing thing that ever happened and the researchers’ ad highly thrilled. It is a discovery that will help them determine the amount of dark matter present through calculating the distortion caused by the galaxies.
Supernova is seen four times, it will arrive in different images and it is possible to take note of the delays between its arrivals. Its bursting is set behind a cluster of very huge galaxies whose colossal mass is said to have distorted both time and space. It has this dark matter that is invisible. However, it can be visualized and it unites the galaxies together. It is said to be present in most of the matters of the universe. The supernova can be magnified, magnification that comes in handy in assisting the astronomers reveal light in which billions of years have been spent travelling the universe.
This discovery has since revealed that gravitational lens will not only make objects be seen from different locations but there will also be dramatical magnification.
