Gravitational lenses to study dark matter
Receive gravitational lens to that highly massive object that has the ability to produce the attraction of gravity. This goes back to the wise words of Albert Einstein who has proven to be a great teacher in the world of science revealing us an interesting way of observing the universe. If we rely on the theory of relativity, we can define as gravitational lenses to that object located between the light source and the person who observes. This contains so much mass that is capable of making the luminous rays of Curven or diverting deforming the space-time.
The importance of gravitational lenses
Many wonder how scientists can observe from so close to objects that are so far away. The truth is that the role of gravitational lenses is essential when this can be achieved. Studying is the use of these lenses in astrophysics has been fundamental in recent years due to different aspects. To begin, the fact that it connects directly with gravity is an open door to study how the dough is distributed by the lens.
In addition, sometimes the image can be much greater, this means that we are able to receive a broader amount of light that crosses the object located in space. This means that even the farthest objects of the universe can become detectable. Finally, the image obtained will allow us to obtain information and data of great precision about the observed object. Without this incredible phenomenon, it would be required of really innovative and high technological instruments that have even been invented so far.
How gravitational lenses are used in astrophysics
Understanding the use that science brings to gravitational lenses is relatively natural. This phenomenon is used in this field of science in order to detect objects located at immense distances and then study them. In addition, it is a way to detect extra solar planets and serves to "shape" those objects whose high level of mass is causing deformations in space-time, although these cannot be captured by telescopes. When it comes to studying dark matter and detecting it in space, these lenses fulfill an essential function. Considering the role of this would put in space when it comes to the formation of structures and the evolution of the galaxies.
Finally we can say then that a gravitational lens is a phenomenon that allows us to have a look from the universe never seen before, opening the way to study and fulfilling a fundamental role in the world of astronomy. They allow us to know even more about the universe that surrounds us revealing us really interesting phenomena.
