The dilemma of the beginning of the universe
The expanding universe that has been explained is the last article, which you, my friend and dear reader, must read to understand more about today's article and they are related.I will leave you the article link here.
We return to today's article, today we will sail in space and in a beautiful and wonderful story to know whether the universe has a beginning or is it eternal?
The expanding universe divided the physical community into two groups,
- A team of them was the LEMAITRE scientist who was mentioned previously in the last article and sees that if the universe was expanding and expanding with time, this means that the universe was small in the past and that it was at one of the stages it was very, very small, to the point that it was a point.And this point is where everything started and that the universe has a beginning.
- The second team, who was the most prominent scientist and physicist, FRED HOYLE, was seeing the universe as opposed to what LEMAITRE had seen. The universe does not have to have a beginning despite the expansion that we see, and that the more the universe is expanding, new galaxies are born in it, so that the density of galaxies will not decrease with time and that the universe will remain eternal, present from the beginning and continuing until infinity
Here we conclude the important question: Does the universe have a beginning, or is it eternal?
One of the most brilliant stories in the history of physics begins, Arno Penzias and Robert Wilsone at Bell Labs.
Bell Labs are strange labs and their research is always strange or useless in the short term.
Bell Labs are strange labs and their research is always strange or useless in the short term.
But this research took nearly 7 Nobel Prizes, and this is the story I'm going to tell you today for one of those awards.
The two scientistes previously mentioned by Penzias and Wilsone have been allowed by a telecom company to use huge Antennas to explore the sky and galaxies.
The idea could be very easy and simple by directing Antennas to space, but after the experiments began there was confusion despite the change of direction, they examined the receptacle accurately, but there is confusion, so think that the reason is the presence of Antennas near the city of New York, and they kept it away, but without suspicion. Still exists,
This confusion lasts for years, until they hear about an article that the New York Times will publish and explain the reason for that confusion,
The strange thing is that this confusion will cause Penzias and Wilsone to win the Nobel Prize in 1978, and the nice thing is that Dennis Overbye in his book lonely hearts of the cosmos, when he wrote about the two scientists
He would say Neither Penzia nor Wilson understood the significance of their discovery until they read about it in the New York Times
This discovery which almost gave importance to the theory that the universe had a beginning
What was in that article that explained the mystery of confusion, and which explains it, but very simply explains, that the universe had a beginning and that it expanded and cooled as it expanded more, then its beginning was often a very hot region, and from the intensity of its high temperature are not galaxies and stars that could not form Even the atoms could not form from the intensity of the high heat, but when the universe began to expand and reached its age to 300 thousand years, where the temperature of the universe came down to 3000 degrees, although it is a very high temperature, it was sufficient for the atoms to form. And light began to liberate and spread throughout The universe is expanding, and the wider the universe, the more The wavelength is long and cold until it reaches 2.7 K.
The same thing was obtained, the equations we talked about in the previous article, if the universe actually had 13 billion years, it was that light that was called Radio Waves that was causing that noise. Or what is called Cosmos Microwaves Radiation, photons since the universe had 300,000 years.
And this conclusive evidence that the universe had a beginning.
