The universe is only 13.8 billion years old, but Methuselah is 16 billion years old. Is the big bang theory wrong?
In the current big bang theory on the origin of the universe, the universe was born 13.82 billion years ago. Time, space and matter were born at that moment. Before that, nothing existed and physics did not exist. Therefore, the research scope recognized by the scientific community is 13.82 billion years ago to now.
Shanghai epidemic isolation, accidental exposure of star luxury houses, sure enough, their simplicity is different from ours
The epidemic situation in Shanghai affects the hearts of people all over the country. But as an international metropolis, we are not only isolated from ordinary people, but also stars living in Shanghai. Peng Yuyan appeared at the nucleic acid detection point, which caused a big shock in the community.
Several”pillars” are as high as 5 light-years. Hubble telescope found that they are collapsing due to”moths”
In terms of shape, nebulae have various shapes, and their diameters are more than several light-years, just like huge pictures painted in the universe. With the progress of human science and technology, we can see clearer Nebula images. Although the nebula images presented to us by NASA have been processed for easier viewing, people still surrender to the grandeur of the nebula.

1.5 billion times bigger than the sun, and the dangerous Betelgeuse could explode at any time? Scientists give time
This symbol represents the sun. Because the distance between Betelgeuse and the sun is about 700 light-years, the position of its own star has been uncertain, so its size can only be maintained in a range. Betelgeuse is about 1.5 billion times larger than the sun.
If the sun goes out, how long will it take humans to perceive it? In eight minutes? 10000 years, to be exact
The birth of life in galaxies is also inseparable from stars. For places with life, the thermal radiation brought by the sun emitted by stars can supplement energy to many organisms and organisms. In terms of macro scale, although stars in galaxies emit electromagnetic storms from time to time, they have both advantages and disadvantages.
