Bell Labs scientists proved Big Bang Theory

“How did we get here?”

The existence about the universe has fascinated mankind for centuries. Many scientists have tried to answer this, including Rev. George LamtreA Belgian cosmologist and Catholic priest. In 1927, he said that the universe was made from a single particle that he called “Primwell Atom”.

That atom later disintegrated into an explosion, Lemtra felt, according to space, time, and a ever-expansion universe, American Museum of Natural History,

The possibility of a lametre’s idea seems familiar, as known as now Big Bang TheoryThe direct proof for theory was not found for almost four decades later, completely by accident.

Bell Labs Researcher Arno penzias And Robert Woodrow Wilson Using radio astronomy using one in 1964 Horn antenna Holmdel is located in the company’s premises in NJ Reflective antenna Was the most sensitive in the world at that time. It was formed to take weak radio signals from space Project Eco, NASAExperimental 1960 satellite communication program. The project successfully did this twice, first for the first time in 1961 via Eco Communications satellite, and the second time through the Telstar Communications Satellite active in 1963.

While Penzias and Wilson were using Holmdel antenna to map Radio signal from Milky WayThis raised a mysterious buzzing noise, which will not go away despite efforts to eliminate it.

The signs, which maintained the day and night, became the cosmic microwave background radiation, which allows the universe – a relic from the creation of the universe – which helped confirm the Big Bang theory. Casual success earned Penzias and Wilson in 1978 Nobel Prize in Physics,

The discovery of Project Eco, Telstar, and cosmic microwave background radiation was recognized as an IEEE milestone at a ceremony held at Holmdel on 25 May at Wilson Park, where Horn Antenna is located.

The evidence of Penzias and Wilson for the Big Bang Theory “shaped our understanding of this universe and in our place,” Thomas Kaflin, 2024 IEEE President, said. News release About surrender.

“Cosmic background radiation, one of the most transformational discoveries in the second half of the 20th century, has also given rise to non-un-ranked communication innovations that address some of the world’s greatest needs, including disaster relief aid,” Kaflin said.

Creation of world’s most sensitive antenna

After the commencement of the Soviet Union in 1957 Artificial satelliteThe world’s first artificial satellite was put into the orbit of the Earth, US government increased its efforts to fund development Non-sighted communication innovation, as detailed in one Engineering and Technology History Wiki Entry,

The government and industry worked together on initiative in laboratories across the country. One of the earlier programs was Eco, which was aimed at receiving two-way voice communication between NASA. Jet propulsion laboratory Goldstone, in California, and Crawford hill In Holmdel, 5 kilometers from Bell Labs Complex.

To make communication possible, the project developed and manufactured horn antenna on the Bell Labs site. The antenna was 15.24 meters long 6.1 meters wide, weighing 16,329 kg. This makes the radio waves inside or out of the horn shape, and the reflector bounced waves in the same concentrated beam – indicated in a curved mirror similar to a giant metal megaphone. Despite its large size, the machine can be targeted properly.

Unlike other antennas, which are tuned only for a frequency, Holmdel antenna worked in a wide band of frequencies, so it can lift many types of radio signals. It can also handle radio waves leading to linear or circular paths.

The design is responsible for the ability to eliminate unwanted noise from the environment.

The receiver was placed on top of the horn, which eliminates the requirement of a connecting line, resulting in external noise and signal loss.

Antenna allowed Project Eco to complete the first high quality long -range voice circuit in 1961 through Eco, a passive communication satellite of her name. A similar experiment was successfully completed through the Telstar satellite after two years, according to this Proposal for IEEE milestone,

In 1964 Penzius and Wilson began using Holmdel Antenna Display your own radio astronomy experiments,

What is that echo sound?

The pair was trying to map a weak map Radio signal from Milky WayHe picked pain to eliminate external noise from land, environment and antenna so that their readings are not affected. Even they cooled the antenna with liquid helium from the receiver on the antenna and pressed the intervention on the antenna -the theoretical temperature on which all the move stops.

Still they kept listening Constant buzzIt was less, stable and 100 times more intense, as researchers expected noise of intervention – and it was coming from all directions in space.

Penzias and Wilson re -designed their efforts to eliminate the intervention, restlessly retained their equipment.

“They went so far that to take the latta and detergent the antenna carefully wash with a drop of pigeons, which were nested there,” Leonardo Cotty told IEEE spectrum In the 2023 article about the search. Collletti is a physics professor Free university of boozen-bozanoin Italy.

But even after all the pair of work, the mysterious discussion continued.

After Penzius and Wilson were responsible for everything, including pigeon pope, he concluded that the radiation he had detected could have been nothing else in the earth, sun, or galaxy.

Later he came to know that researcher and astronomer physicist Robert H. Dike, P. James PeelasAnd David Tod Wilkinson But Princeton University Cosmic microwaves predicted the existence of background noise, which “he believed with Big Bang, according to” An entry On Nokia Bell Labs website.

“As it turned out,” the article says, “the radiation detected by Penzias and Wilson was an ideal match that was predicted by Princeton researchers.”

Horny antenna

Holmdel Antenna was nominated in 1989 National historical siteBut in 2021 Nokia, who acquired Bell Labs, sold 43 acres to the technology entrepreneur Rakesh Antala,

The following year, the Holmadel Planning Board voted for a study to consider re -reviewing the site as an area required for redevelopment.

The local community started a campaign together and A. Online petition to save antennaThe township eventually gained ownership of the horn antenna site after a comprehensive legal process. Last year dedicated it Dr. Site as Robert Wilson ParkHonoring it as a place where “we gained an important understanding of the birth of our universe.”

A plaque, a plaque identifying the IEEE milestone designation, is displayed in the lobby of the AT & T Labs Science and Technology Center in NJ’s Midletown, which is about 7 kilometers from the CrFard Hill. The plaque reads:

In 1959–1960, NASA and AT & T developed a satellite meaning station at Holmdel, NJ, including a novel tracking horn -Feller antenna, Messer Primlifier and FM Demodeulator. Prithvi Station demonstrated the first high quality long distance voice circuit through the Eco Passive Communication Satellite in 1960–1961 and through the Telustar Communications Satellite active in 1962–1963. The experiments conducted in 1964–1965 provided the first indication of the cosmic background radiation associated with Big Bang.
