Astronomers have caught the first glimpse of the planet originally formed after the Big Bang 13.8 billion years ago, potentially detecting the role of mysterious dark matter, this time more important than the Big Bang. ” We see the origin of humanity.” “

There may be a new understanding of the nature of dark matter
The study, supported by the Arizona State University Foundation and sponsored by the study, found this very weak signal, opening a new window to the universe and a new dark matter (dark matter) nature
Dark matter cannot be studied by electromagnetic observation, that is, matter that does not interact with the electromagnetic force. We can only know that from the effects of gravity, and we know that there is a lot of dark matter in the universe.
Astronomers don’t actually see anything, and are indirectly inferred from the frequency changes of waves generated by wireless signals.
The faint wireless communication device from outer space was detected by a table-sized wireless separator installed in the Australian desert, which cost less than 5 million yuan.
Bowman said the signal came from the first object formed when the universe emerged into darkness, 180 million years after the Big Bang.
The astronomers say that seeing even a little signal when the universe just shines makes more sense than knowing the Big Bang. Because life comes from the stars, ” I saw the origin of man.” “

The biggest breakthrough since the discovery of gravitational waves
The decade-long exploration yielded results several years ahead of expectations, known as the biggest astronomical breakthrough since the discovery of gravitational waves in 2015.
To the experts’ surprise excitement, the signal showed unexpected low temperatures and abnormally significant wave frequencies, which astronomers believe could be caused by invisible dark matter.
If so, it would be the first demonstration that dark matter that scientists have searched for for decades does exist.
Bowman agreed that the finding could also be proven in independent experiments, but his team spent two years working against validation.
Research shows that the early universe was twice cooler than originally estimated, at minus 270 degrees Celsius (minus 454 degrees Fahrenheit).
Bakana, an astronomer at Tel Aviv University, said the unexpected low temperature may have been caused by the interaction between ordinary matter and dark matter, taking the energy away from the latter.
The common matter that forms everything that humans can see and touch is only 4.9% of the total mass of the universe, dark matter is 26.8%, and the remaining 68.3% is dark energy.
Dark matter is invisible and can only be perceived by its gravitational pull of other matter in the universe.
Scientists believe that for about 400,000 years after the Big Bang, the universe is black and cold, filled only with hydrogen and helium. Stars then formed in the highest concentration of cosmic clouds; the human sun and solar system formed about nine billion years later.
