Scientists have found a way to explain anomalies that do not fit the current hypothesis regarding the age of the Universe. It consists of refining the existing hypothesis of tired light.
this is what we know
It is generally accepted that the Big Bang occurred nearly 13.8 billion years ago. The experts reached this conclusion following analyzing the phenomenon that occurs when the wavelength of electromagnetic radiation for the observer increases in relation to the wavelength of the radiation emitted by the sources. It was called “redshift”.
Everything would be fine with this hypothesis, but there are several anomalies that do not fit with it. For example, the James Webb Telescope found several supermassive galaxies and black holes at the dawn of the Universe that should not exist there. Another problem is the star Methuselah, also known as HD 140283. It is believed that its age may exceed 14 billion, that is, it must be older than the Universe.
The light aging hypothesis was proposed almost 100 years ago. The astronomer Fritz Zwicky suggested in 1929 that light loses its energy as it travels through the Universe. The reason is the collision of photons with cosmic dust, gas and force fields.
This hypothesis was refuted, but Canadian scientists have recently revised it, updating the model with Paul Dirac’s equation, which describes the interaction of particles at the quantum level. They now suggest that the age of our universe is regarding 26.7 billion.
