There are only four forces of nature.
Quantum mechanics integrates three natural forces.
The theory of hypergravity unites four forces in 11 dimensions.
Superstrings, which unite all forces and the laws of nature.
All theories fail completely at the singularity.
The universe is flat.
The universe is blazing when it is young and gets colder as it ages.
The diameter of the universe is more than 150 billion light-years.
The universe has no center.
Saturn can float on water.
Any atom in your body could come from any planet in the universe.
The size of the Sun is about 1.3 million Earth.
The naked eye can only see 5 of the universe.
The solar system has been spiraling away from the Milky Way.
Every day, 27.5 million stars are born and die.
The Hubble telescope can see light from 13 billion years ago.
The day of the Moon is 708 hours.
Pluto and Venus.
1. Ice on Pluto is harder than steel.
The average temperature on the surface of Pluto is -220°, which is not difficult to understand, because it is far away from the furnace of the sun, so the temperature is naturally low.
However, because of the tidal locking, the back side of our moon does not see sunlight all year round, so the temperature on the far side of the moon is also very low, and even the lowest known temperature in the solar system - 238° is measured in a crater on the far side of the moon. At such low temperatures, the strength of the ice has killed the steel.
2. Venus is getting longer every day.
As we all know, one circumference of the earth around the earth's axis is one day, and one circumference of the sun is the time of one year. The time it takes for each planet to move like this is different.
The weird fact is that Venus needs 243 Earth days to make one orbit on its axis, but only 225 Earth days to orbit the Sun. Venus is a year behind before a new day comes. In this way, living on Venus is not a birthday that can be celebrated every day.

2. The mainstream view in modern cosmology is that the origin of the universe originated from a large state, which evolved from a state of extremely dense and extremely high temperature in the past, and reached a state through continuous expansion, which is called the grand theory of the universe or the theory of singularity.
3. We don't know what caused this big **. The light emitted by the big ** is still spreading outward. The resulting gases and clouds, dancing, spinning, and aggregating into embryonic galaxies.
4. The universe is a general term for the vast space and the various celestial bodies and diffuse matter that exist in it. The origin of the universe is an extremely complex issue. Modern astronomical observations prove that it is in constant motion and development.
For thousands of years, scientists have been searching for when and how the universe came to be. Many scientists believe that the universe was formed by a large ** that occurred about 14 billion years ago.

Anonymous users2024-02-051. The Rising Universe is a general term for the vast space and the various celestial bodies and diffuse matter that exist in it. The origin of the universe is an extremely complex issue. Modern astronomical observations prove that it is in constant motion and development.
For thousands of years, scientists have been exploring when and how the cosmic laughing branch was formed. Many scientists believe that the universe was formed by a big ** that occurred about 13.8 billion years ago. At first, there was no space, no time, and the reason was not known, space began to explode, and vibration made matter born.
The big ** caused the space to expand, the space of the universe continued to expand, and the temperature also dropped accordingly, and later all the galaxies, stars, planets and even life in the universe appeared one after another.
2. The latest research puts the diameter of the universe at 156 billion light-years or even larger.
3. The observable age of the universe is about 100 million years.
Knowledge about the universe:
1.In the constellation Aquila, 10,000 light-years away from Earth, there is a cloud of alcohol, 1,000 times the diameter of the solar system. It contains the same amount of ethanol as 400 (400x1024) bottles of beer. >>>More
1. Tea is sweet, bitter and slightly cold, and is a traditional natural health drink in China. People have found that there are more than 500 kinds of chemical components in tea, the main components of which are caffeine and tea polyphenols. >>>More
Thought is based on the tangible world, (explain, what is left of our mind other than what we hear, see, feel, smell and taste?) The universe constitutes our existing tangible world, so the mind cannot transcend the universe. The universe increases or decreases according to the desires of thought, for example, in the past, scientists used molecules as the elementary particles of matter, and matter was made up of molecules. >>>More
The universe has been around for 13.7 billion years. >>>More
Recent research has shown that there may be other universes.
