Scientists measure the total amount of light produced in the universe

Stars emit 4x10 ^ 84 photons of light since the universe was formed 13.7 billion years ago, according to a new study.

The team of researchers recently claimed to have measured all the light produced by stars in the universe so far. The exact number given is 4x10 ^ photon photons (photon is the smallest light unit). The data was collected by NASA's Gamma Fermi telescope for 9 years.

"From the data collected by the Fermi telescope, we were able to measure all the light emitted by the stars so far, " astronomer Marco Ajello from the University of Science Clemson said.

According to him, this is the total amount of light generated in a few hundred million years since the stars began to form after the Big Bang. It is estimated that about one trillion trillions of stars are formed in the universe.

"Measuring the amount of light emitted by stars living in the galaxy helps us better understand the evolution of stars, as well as a deeper understanding of the universes that generate sources. Its bright , "said Ajello.

Even so, Clemson University scientist admits that 4x10 ^ 84 is just a relative number, because a lot of light is created in the universe but cannot reach the Earth.
