Universe had a beginning

(ORDO NEWS) — It is easier for many to think that the Universe has existed forever and there can be no beginning.

There is nothing wrong with this, because for a long time the greatest scientists, who had limited knowledge, also thought so.

Modern science says otherwise, and today there is ample evidence to indicate that the universe had a beginning.

First Edwin Hubble, and then Einstein, observing outer space through a Californian telescope (the most powerful at that time, allowing you to see galaxy clusters), made sure that galaxies are continuously moving away from the Milky Way

The farther away a galaxy is, the faster it is receding.

Initially, Albert Einstein was also an adherent of the theory of the “Stationary Universe”, and before him Isaac Newton was sure of this.

However, working with verifiable data from direct observations, the great physicist of the 20th century came to the conclusion that the universe must be expanding.

The speed of removal of galaxies is determined using a spectrograph: the light of distant galaxies is passed through a prism, color decomposition occurs, and the farther away the galaxy is, the more red color is obtained.

This is how the term “redshift” was born, which is a criterion for the remoteness of objects.

Therefore, if the process of the expansion of the Universe could be rewound like a film tape, then we would see how the galaxies approach each other, get closer and closer, and then merge into one point.

In 1987, physicist Robert Woodrow received the Nobel Prize for the discovery of microwave cosmic microwave background radiation – thermal radiation that evenly fills the Universe, which arose during the era of the primary recombination of hydrogen.

This once again proved that initially the Universe was in a singular state (point), but at some point in time it began to rapidly expand in all directions with the release of an incredible amount of energy!

This sudden expansion is known today as the Big Bang.

The term was coined by astronomer Fred Hoyle , who for many years was an opponent of the theory of the origin of the universe from a point.

Speaking on the air of the radio station, Hoyle jokingly called the process of spontaneous expansion of space-time the “Big Bang”, but everyone liked this expression so much that they decided not to change it.

The whole world around us with its endless expanses is the result of the Big Bang . Scientists cannot yet explain exactly what caused this event, but they know for sure that the Universe did have a beginning.

It is likely that every fraction of a second other Universes are born or even “bud off” from ours.
