A new study by an international team of astrophysicists says that the age of the Universe is 13.8 billion years. Thus it is possible that the disputes about her age.

The study was conducted using data that were collected Cosmology Telescope in the Atacama (ACT). This was attended by 41 scientists from the research Institute from seven countries.

The object of study became the oldest light in the Universe, which dates back to the Big Bang – the so-called cosmic microwave background. With the help of the ACT was received it image. This light that was emitted through 380,000 years after the Big Bang, different polarization (represented by red or blue colors). Astrophysicists used the interval between these variations to calculate new estimates of the age of the Universe.

“In our work, we are restoring the “baby photo” of the Universe to its original state, eliminating the wear of time and space, which distort the image. Only after seeing this “baby picture”, we can more fully understand how our universe was born,” says nilima Segal.

The new estimate coincides almost exactly with the measurements of this “ancient light”, which was made with the help of the satellite Planck. It is possible that these confirmations will give reason to believe that the age of the universe still is 13.8 billion years. As recently put forward the idea that the universe is younger by a few hundred million years.

In addition to the age of the Universe, scientists have calculated more and the speed at which it is expanding. Measurements using ACT almost exactly correspond to previously obtained data from the satellite Planck and account for 67.6 kilometers per second per megaparsec. This means that an object that is at a distance of 1 megaparsec (about 3.26 m light years) from Earth removed from it at a speed of 67.6 kilometers per second due to the expansion of the Universe.
