Dark matter is a mysterious and invisible material form. We believe that it accounts for about 27%of the known universe, about 6 times more than visible substances. Although it accounts for a considerable proportion in the universe, since the Swiss American astronomer Friez Zwellia first proposed its existence in 1933, we have been unable to understand what kind of substance is. So far, dark matter has never been directly detected by humans.

Although the James Weber space telescope cannot be directly seen "seeing" dark substances, scientists believe that by measuring its impact on the surrounding environment, this telescope can give some answers to the main questions about dark matter, and this process will greatly promote our right to right to right. The understanding of the entire universe.

Scientists do not know what the dark matter is composed of, and they are still trying to study a method that directly detect it. At present, scientists are continuously optimizing this method in the large -scale strong collision (LHC) experiments of the European Nuclear Research Organization (CERN). Unlike these experiments in progress, the James-Weber space telescope cannot directly detect dark matter, but it can study the effects of dark matter on normal and visible substances.

"When you observe the dark matter, you seem to always adopt a" roundabout "method because you can't see them. The dynamics of galaxies. "Klaus Pontopoden, a project scientist at the Institute of Space Telescope Science, told Space at a press conference in May.

For example, as a "roundabout" method for detecting dark matter, astronomers can use existing technology to measure the quality of stars and galaxies. The main evidence of the existence of dark matter is that if there is no visible quality, many galaxies cannot move as they are doing now -they will not even exist at all.

In order to help astronomers more accurately locate the dark matter, James Weber Space Telescope will take extremely clear images. From the research staff, it will observe the interference caused by the gravitational lens effect, which will point them to point out that the "invisible quality" place will be pointed out The lurking corner. The gravitational lens effect is a phenomenon described by Einstein's general theory. Under this phenomenon, when a beam of light passes a large -quality object, because the space -time structure is slightly bent, the direction of the light will occur slightly.

When imaging for a distant galaxy, the James-Weber space telescope can find these quality and determine what "missing" (or unable to observe) -This is likely to be dark matter. "James-Weber Space Telescope is particularly suitable for this type of surveying and mapping, because the extremely clear images it output will observe very small interference. And because it can see such a deep space, James Weber space telescope can be exposed to contact To more background galaxies to measure the interference caused by this gravitational lens effect, "NASA introduced in an overview information about James Weber Space Telescope.

"Moreover, James Weber Space Telescope will be able to observe many statistics about galaxy evolution." Overview data supplements, "Scientists can compare these observations with how the dark matter play in this process, so as to thus There is a corresponding understanding of the quantity and nature of dark substances in galaxies. "

The design of the James-Weber space telescope is to see a farther space we can see before, and this will also "see" farther time. By conducting these observations in the deep space, the James-Weber space telescope will continue to study the early beginning of the universe and its galaxies, as well as the role that dark matter may play in their evolution.

Ponzo Piddan said that scientists are continuing to understand the formation time of early galaxies in the universe. This formation process is "driven by dark matter evolution models and set different parameters for the original galaxy at different times".

Poundpidan added that the James-Weber space telescope can be used to measure some basic parameters of the earliest galaxies in the universe, let us better understand their light and quality distribution, and so on.
