With the continuous development of human science and technology, we can also use the astronomical telescope to view the Nine Heavens Galaxy. The “big hero” in human history, the Hubble Telescope, once photographed the incredible Einstein Cross in the deep space. For humans, what kind of existence is this?
The mysterious phenomenon of gravitational lensing
The realization of the human spaceflight dream is largely due to the theoretical achievements of physics in history. In the long history of human civilization, many great physicists have emerged.
These physicists use their own wisdom to promote the development of civilization, shining like stars in the river of wisdom. And Einstein is the brightest star in human history.
In his lifetime, Einstein used his wisdom to travel through thousands of galaxies and spy on the mysteries of the deep space of the universe.
The gravitational lensing effect proposed by Einstein is actually equivalent to a kind of deep space prediction. Einstein once believed that in the vicinity of massive celestial bodies in the deep space of the universe, due to the gravitational effect of celestial bodies, space-time will have a certain distortion phenomenon.
Under the action of this distortion, when the light passes through this massive celestial body, it will also be distorted. If an observer on Earth can spot a supermassive object in the light, it is likely to see one or more deep-sky images formed by the distortion of the light.
On the basis of gravitational lensing, Einstein speculated that there is a Pegasus galaxy in the deep space 5 billion light-years away from the earth. The Pegasus galaxy is likely to form a quadruple image with some nearby quasars. From this, we can also speculate that the galaxies in the universe are actually similar to some extent.
However, due to the limitations of science and technology at that time, 5 billion light-years away is a deep space that is simply untouchable for humans. It is impossible for us to observe the Pegasus galaxy and the quadruple image that Einstein said through the astronomical telescope. , so Einstein’s gravitational lensing phenomenon could not be proved by corresponding scientific evidence at that time.
Einstein Cross in deep space
Human history is constantly advancing, and human technology is constantly iteratively updated. With the development of modern science and technology, many “impossible” in history have also become “possible” with the support of technology.
With the development of technology, mankind has also launched a further exploration of the deep space of the universe, and the deep space images that Einstein said were not successfully captured by the Hubble Telescope.
In November 2014, Hubble, a “deep space veteran”, once again brought surprises to people. Astronomers have discovered a special image in the deep space images returned by the Hubble Telescope. On this photo, we can see five large blue light spots.
They come from the distant Draco star cluster, flashing blue light in the deep sky, appearing in the deep space of the universe in a cross-distributed structure. In the photo, we can see that the spot in the middle is the largest and occupies the center firmly.
The remaining four blue light spots are like “guardians”, symmetrically guarding around the central light spot in a “cross-shaped” structure.
This discovery is undoubtedly a huge surprise for mankind, because they successfully confirmed the gravitational lensing effect proposed by Einstein. After half a century, mankind has finally observed the magical astronomical phenomenon predicted by Einstein.
The astronomical image is also known as the “Einstein Cross” because the five blue light spots look like a giant cross in appearance.
The meaning of Einstein’s cross
The appearance of Einstein’s cross is a treasure-like discovery for astronomy. It not only successfully confirmed the prediction made by Einstein, but also successfully reflected that there is indeed a “galaxy projection” phenomenon in our universe, which further deepens human’s cognition of the universe and makes our astronomical The business has entered a new field.
For many people, it may be thought that the Einstein Cross represents five galaxies, but this is not the case. In the universe, they just exist like a “mirage”.
The remaining four spots surrounding the main spot are just projections of the main spot, not real galaxies. This place is like the mirages we usually encounter in the desert. They are just phenomena caused by the refraction of light. For us, we cannot touch or touch them.
After the appearance of Einstein’s cross, the astronomy community has been promoted to strengthen the search for dark matter. For a long time, dark matter is the most mysterious matter in the universe. It is neither visible nor touchable, but it is like a “ghost” that exists around us all the time.
Perhaps the exploration of dark matter will further deepen our understanding of the universe and at the same time reveal the mysteries of the universe.
In any case, the appearance of Einstein’s cross is of great significance to human beings. It is like a time and space shuttle, taking us to appreciate the deep space scene in Einstein’s mind half a century ago, and feel Einstein’s star map of the universe.
Epilogue
I believe that with the continuous development of human civilization, we can also observe more magical astronomical phenomena in the universe. The mysteries of the universe can also be revealed by humans one day in the future. The journey that human beings are currently sending to the universe is already a miraculous existence.
