An article titled Webb's telescope overturned the Big Bang theory was reprinted on the Internet, and people were exclaiming that Webb's 10 billion US dollars had not been spent in vain.
However, this article has caused concerns among countless astronomical workers, who believe that such fake articles will mislead people's understanding of astronomy.
Web Telescope worth tens of billions
So, is the Big Bang the origin of the birth of the universe? Is Webb's telescope consolidating this theory or overturning it?
How did our universe come about?
How does the universe originate
Is the Big Bang true or false?
The Big Bang is generally considered to be the theory of the birth of the universe , but in fact, the Big Bang theory of is not the truth, but a hypothesis . However, there are many astronomers who support this hypothesis, so is tentatively designated as the origin of the universe .
If there is enough evidence to prove that the Big Bang hypothesis is wrong and supports the new hypothesis, then this theory will be replaced.
The development of science has always been that theories exist first and then verified. If is successfully verified, then the old theory will be replaced by the new theory. If the verification fails, it means that the new theory is not perfect.
Cosmic Big Bang
For example, many theories of Aristotle only exists in history books but not in physics books . The reason is that Galileo , Newton , etc. have verified that his theory has limitations. Astronomers such as
Lemait , Hubble were the first to propose the theory of the origin of the Big Bang, especially Hubble. When observing the universe, they discovered a redshift phenomenon .
red shift phenomenon is that the wavelength of visible light in becomes longer, and finally reaches the wavelength of infrared of , and humans can no longer see it.
The reason for this phenomenon is that the universe is expanding . Hubble believes that galaxies are far away from each other, and that this distance is regular. From this, he deduced the formula for Hubble's Law : Vf = Hc x D.
Astronomer Hubble
Then Hubble pushed back along the galaxies, found that all galaxies came from a point , which may be the origin of the universe.
However, how did a point change from point to matter?
At this time, a man came into the sight of the astronomer, and he was Einstein .
Einstein himself also studied the universe . Although this is just his interest, he had a profound impact on later astronomers.
Einstein also studied astronomy
He proposed cosmic phenomena such as gravitational field , wormhole , and especially his theory of relativity. Black holes are the extension of his general theory of relativity .
Similarly, according to Einstein's theory of relativity, astronomers believe that today's matter in the universe originates from the explosion at that point, and the energy generated by the explosion of becomes the mass of the universe .
This explosion occurred in about 13.7 billion years ago , and our solar system was born about 4.6 billion years ago, so our location is a certain distance from the center of the universe.
The universe was born about 13.7 billion years ago
The strongest "Ace Pigeon"
James Webb Telescope is the successor of Hubble Telescope . It is more advanced than its predecessors because it observes infrared rays.
Hubble once mentioned that there is a redshift in the light in the universe. Because the universe is expanding, all galaxies are far away from each other, so there will be fewer and fewer galaxies that humans can observe in .
However, if we can catch the light after redshift , then we can catch up with these distant galaxies .
Therefore, based on the original Hubble, the Webb telescope chose to observe infrared rays .
pioneer Hubble
However, the space journey of Webb telescope did not go smoothly . According to the plan, it should have launched in 2007, but it was repeatedly postponed due to various problems.
Its cost also increased from the initial $500 million to the later $10 billion . Every year NASA announced that it would launch, but it would be postponed for various reasons. Over time, people would subconsciously react to the news of the launch of the Webb telescope.
after 14 years of "pigeon", Webb Telescope finally successfully launched and started working in 2022. Before officially taking office, it experimentally took several pictures, with a clearer clarity far exceeding its predecessor Hubble Telescope.
"Ace Pigeon" Webb Telescope
Wait until the Webb Telescope really sent back the photos, The entire astronomy community was in full bloom , because a photo of Webb can be studied for several years, and they can gain a lot of new knowledge.
However, not long after the photo was sent back, the new discovery of Webb's telescope appeared and the claim that the Big Bang of the Universe appeared, which confused countless astronomers. Whose research was so fast?
Photos taken by Webb
University of Kansas Astronomer Allison Kirkpatrick believes that this is a fake news. First, the article was published in a place called "Academy of Arts and Thoughts" (iAi) , which is not a strictly authoritative astronomical institution.
Secondly, the beginning of this article is "shock" and "panic" and other words, with a gaze-attracting attitude. Generally, rigorous academic articles in will not think of starting like this to attract people.
Allison Kirkpatrick is even more angry that this article also quotes papers she once published, but what she said in was misinterpreted by , which became the basis for overthrowing the Big Bang.
Hubbour and Webb's use of one position
In fact, Allison Kirkpatrick is a supporter of the Big Bang theory , and she has been working in this area.
After learning that this article was widely reprinted, she expressed her concern and at the same time she expressed her gratitude because someone called or emailed her, which showed that people were still skeptical about this article.
Allison Kirkpatrick said that although she supports the explosion theory, if Webb Telescope really finds to overturn the old theory, she will accept it happily, but she will not accept this kind of fake news.
Astronomers clarified the news
Webb's real discovery
Webb's telescope data transmitted back requires scientists to process it in the background, and then make it into pictures and announce it. all the images are G-started .
Because the resolution of images is too high, , and by enlarging the image, you can see the later galaxies. One photo is enough to study for several years.
In addition to shooting the long-distance universe, the Webb Telescope also photographed the close-distance celestial bodies . It observed Mars , Jupiter and Neptune among the eight planets .
Neh and its big black spot
Among them, it took Nehl's halo , which is the clearest halo photo in 30 years.
Due to the special optical processing system of the Webb Telescope, the photos it took are different from the original Hubble. Hubble uses visible light, so what Hubble takes is what we can see with our eyes.
Webb is different. Take Jupiter taken as an example. The entire picture of is a dark red , which is very different from the orange-red Jupiter we think.

These dark red lights are infrared rays emitted by Jupiter's atmosphere. Scientists can use these photos to study Jupiter's gas composition from another direction.
Webb also "sees" the atmosphere of Mars . Scientists have always known that the atmosphere of Mars is very thin, but they are not clear about its distribution.
This time, people clearly saw where the atmosphere of Mars is located in , which is a good reference for choosing places when logging on Mars in the future.
It also discovered carbon dioxide in the atmosphere of the exoplanet exoplanet , which help people study whether alien life really exists and how many super earths there are outside the system.

us and the universe
Whether it is Hubble or Webb telescope, they are all human eyes facing the universe , helping us see a longer distance.
It is hard for you to imagine that the Hubble telescope is actually a failed . It did not achieve the goal originally planned, but this does not affect its becoming the greatest astronomical telescope in human history .
Webb was not favored at first, and one "pigeon" and another, so people thought it would float with water, but Webb still withstands the pressure and successfully launched it. Just a few photos sent back from made the astronomy world so shocked .

Real astronomers hope that the Webb Telescope will have new discoveries , which is also the original intention of launching the deep space telescope.
As Allison Kirkpatrick said, the Big Bang is a hypothesis, does not rule out the possibility that it will be overthrown , but it is not "overthrown" in the form of fake news.
In fact, among astronomers, there are many people who do not support the Big Bang . They have also criticized the Big Bang theory for imprisoning the thoughts of astronomers, resulting in the fixed direction of everyone's research.
These astronomers also put their hopes on the Webb telescope, hoping to obtain more evidence to refute.
The Big Bang is still a hypothesis
They also don’t want anyone to attract attention on the topic of “Webbe Telescope overthrows the Big Bang”. science is serious!
