Is there dark matter in our solar system?

Current cosmological models suggest that our universe began 13.82 billion years ago in a big bang, the instant at which time, space and matter were born.

However, what few people know is that ordinary matter or baryonic matter, which we can see in the universe today, only accounts for 4.9% of the total mass and energy in the universe. The remaining dark matter (26.8%) and dark energy (68.3%) are the mainstream of our universe and can really affect the fate of the universe.

Although science has not yet found the true body of dark matter and dark energy, the large-scale structure of the universe under the cosmic hole has indirectly proved the existence of dark energy 39bet-xsmb-xổ số tây ninh-xổ số binh phước-xổ số binh dương-xổ số đồng nai, the accelerated expansion of the universe is also evidence, and the dark matter can be obtained from the abnormal speed of the stars outside the galaxy.

Dark matter has long been considered the galaxy's glue, because it provides extra gravity so that stars on the outside of the galaxy don't spin too fast and get thrown out of the galaxy as stray stars, and the galaxy doesn't spin too fast and break apart.

So is there dark matter in our solar system?

Astronomers think: between the distribution and density of dark matter, dark matter in the void universe certainly exists several pieces, which have been floating in the universe and release the extra gravity, but when we look at its direction, we can only see a void, so even if dark matter pieces to the solar system, we can't see it.

6dab09bfadb3d662c1d1f77f95e82d7aBut physicists believe that dark matter, which cannot be directly detected but exerts a gravitational influence on other objects, is also made up of microscopic particles that are gravitationally clumped together, a typical dark matter clump the size of a solar system.

It is these wandering within the galaxy of dark matter clumps, providing additional gravity, thus affecting the motion of the stars and galaxies, and the reason we have not been able to detect dark matter, because we haven't dark matter clumps near to the solar system, they were close enough to the solar system, such as dark matter exert extra gravity can be high precision of the earth gravitational wave detector found, Just like when gravitational waves were detected.

One might wonder if the dark matter clumps, about the size of a solar system, would cause gravitational interference in the solar system, causing the Earth to fall into the sun, or the moon to fall into the Earth.

But this is not going to happen, because the density of dark matter clumps is very small, and in the whole volume of dark matter clumps size is equal to the solar system. Even if it is completely with the solar system, life on earth, we will not be affected by any, only the high precision of gravitational wave detector have a reaction, tell us about dark matter.

If the proportion of dark matter is correct, then the occurrence of "dark matter clumps passing through the solar system" should be about once every 20 years, which is equivalent to once every second in the 13.82 billion years of the universe's history, which is enough to show the impact of dark matter on ordinary matter in the universe.

And, of course, if the future ultra-high precision of gravitational wave detector did not detect the presence of dark matter, maybe there will be many physicists who don't believe in the existence of dark matter, will think it is only a hypothesis of extra gravity, resulting in abnormal velocity stars within the actual reason, just we don't yet know.

But no matter how, at least for the present physics, dark matter and dark energy is the biggest mystery of another, it is enough to affect the second 100 issues of human civilization, considering so far all human theory and technology is based on ordinary matter level, dark matter in the future if found, there must be more theory and technology being developed.

By then, human civilization may really understand the nature of the universe, and evolve rapidly from a planetary civilization to a galactic civilization, or even a cosmic civilization.
