Chemistry Are there elements in the universe that are not on Earth?

There may be, but not for sure.

At present, human beings have synthesized many heavy elements, but it is not certain whether there are still conditions for the synthesis of heavy elements in the universe.

Among stars, there are generally few heavy elements, and the highest is only iron, so it may exist in some cold stars with suitable conditions.

In the universe - there should be elements that are not on Earth.

However, at present, the level of human science and technology is limited, and some things cannot be detected at present.

Macroscopically: the earth belongs to the universe, not the other way around (the earth is only a member of the vast universe) as - black, white, red, green. And so on, these colors that we can see with our eyes.

It also belongs to the category of spectrum, and those that are not on the earth do not mean that there is no in the universe, just like infrared light and ultraviolet light that are invisible to the naked eye.

The power of a black hole can absorb all the energy and even distort time.

There must be, otherwise there would be many Earths in the universe.

Scientists won't be exploring the universe forever.

There must be, and scientists are still looking for it, but there are many places where they can't go, and they can't study without samples.

Hehe, the universe is boundless, the earth is just a grain of dust, the earth is a planet in the solar system, and the solar system is in the Milky Way, so there may be as many as 1 billion galaxies as large as the Milky Way in the universe, not only the universe, but also some matter on the moon that is not available on the earth.

In the development of human chemistry, there are very few chemists who can go down in history. The exception was Mendeleev, the founder of the chemical element table, and anyone who aspired to work in chemistry had to bow down in front of Mendeleev's podium. In the eyes of a chemical dog, a list of chemical elements is the whole world.

Let's think about whether the elements of the entire universe are gathered in the chemical element table. In other words, all the elements in the universe are on Earth, in the hands of human beings? Of course it is no.

In the eyes of experts in basic theory, the use value of the elements is the same as that of the creator. If you discover a new element, this year's Nobel Prize in Chemistry will be yours by no surprise.

This is the value of discovering the new element, and you have been at this time as the Creator. Even if the element can be produced, a list of chemical elements is obviously not enough. Mendeleev's list of chemical elements has been almost perfect.

It can even analyze the parts of unknown elements and inspire everyone to feel with their hearts. But the quest for chemical production of new elements is never-ending. People have already produced more than a dozen elements by manpower, and the list of chemical chemical elements of 118 elements is nothing more than everything in the universe that people understand.

Under human observation, the entire universe seems to stop there, with only 118 elements, neutron star mergers and supernova explosions, which are the heavy element production factories of the universe. It is even believed that there are only 98 elements in the universe, and that the elements that people can generate cannot be generated in the universe.

If star orbits are affected by supernova explosions of massive stars, then the stars formed from these orbits will have the same types of elements as on Earth, with only a few differences in content. Naturally, other planets do contain a very small number of elements that are not found on Earth, and the content of such elements should be extremely low. In addition, it is unlikely that there will be particularly high mass primors on other planets, and because transuranic primors are very unstable, they are very susceptible to nuclear decay into more stable and lighter molecules.

Because of this, the elements created on 94 can generally only be stored for a short period of time. In addition to ordinary chemicals composed of various elements, there is also dark energy in the universe that has not been understood until now. Based on observations, it is inferred that dark energy is much larger than that of ordinary chemicals, and that they are no longer composed of chemical elements as we know them.

No. Because the chemical elements on the earth are very limited, and the universe is very large, and there are many unknown elements, the chemical elements on the earth are not all the elements in the universe.

The chemical elements on the basis of point 1 must be all the elements in the universe, because they are the whole elements, and they have a cosmic transformation, and this speed can reach a standard.

I don't think it's all the elements in the universe, after all, the universe is infinite, we have only explored a small part of it, and there are still a lot of unknowns.

I'm not a major in physics or chemistry, but I think there must be something that the earth doesn't have. Although the periodic table is now known from the first element to more than a hundred good, the structure of the same element on Earth is the same as that of other places.

The question is about matter, so matter is not only a question of elements, but also substances formed by different element ratios. For example, if coconuts don't grow in the north, it seems reasonable that there is no other place on Earth in the universe.

First of all, I don't believe that there are only human beings in the universe, otherwise human beings would be too lonely in the vast universe. So how can we prove that things that we have not seen do not exist, so in our limited cognition, we should not give a definite definition of what we do not know.

For us, accurate physical laws may not necessarily be applicable to any environment, although there is rationality in the current understanding of human beings, but for the unknown, we can only use our current cognition to speculate, and the verification will be handed over to the scientists who have the ability to explore the universe to a certain extent in the future.

We have all seen a lot of science fiction movies, and the things in science fiction today are all imagined by human beings, so the things imagined by us human beings may indeed exist in some parts of the universe, and now our human beings have too little understanding of the universe, and when they do not really reach the depths of the universe to explore, all the current theories can only exist in the theoretical stage, and we can only conduct theoretical research, and how the specific facts can only be left to the future to verify.

We know that all kinds of matter in the universe mainly come from the nuclear fusion reactions in the universe and stars. From the moment the universe was born, the chain of formation of various substances began. There are now more than 90 natural elements on the earth, as well as synthetic elements, adding up to a total of 118 species.

Could this be the total amount of elements in the universe? In the unknown corners of the universe, will there still be chemical elements unknown to mankind? In the eyes of physicists, the probability of the existence of unknown elements is very low.

In nuclear physics, scientists can calculate that there are components in the universe other than known elements, but their chemical properties are very unstable, and the probability of discovering them is very low. The last element of the periodic table, element 118 OG-294, was discovered in 2006 and has a half-life of only seconds, which is an element that exists almost only instantaneously.

Using their own technology, scientists have synthesized 23 elements, from 95 to 118, which is an amazing achievement. But so far, humans have not mastered the method of synthesizing Element 119, because it is only a theoretical thing, and it is very difficult to turn it into reality.

There is a classical "island of stability" theory in physics, which is a conclusion drawn after summarizing the stability of various elements. Scientists have found that if the number of protons and neutrons in a nucleus is one in 126, the atom will exhibit very stable properties. For example, if there are 50 protons of tin in the nucleus, the nucleus is very stable.

However, transuranic elements have a short half-life, and as the atomic number increases, the nucleus becomes more and more unstable. It's getting harder and harder to synthesize or discover it. Scientists propose that when the periodic table develops to element 126, it may be a very stable element, but perhaps the atom will not reach element 126 at all.

In the event of a cosmic event, supernova explosions may form matter larger than Element 118, but their half-lives will be quite short, and they cannot be captured by the current technological means of mankind. What do you think?

It is the ordinary existence of matter in the universe. In the vast universe, although it is a high vacuum, there are still hydrogen molecules and hydrogen atoms. Space around the Sun is scarce, with only one hydrogen atom per cubic centimeter, and more in interstellar molecular clouds, reaching about 40,000 per cubic centimeter.

Of course, this is very thin compared to the Earth's atmosphere, which contains 40,000 trillion nitrogen and oxygen molecules per cubic centimeter.

Scientists envision installing a huge funnel-shaped hydrogen collector on a spacecraft that already has considerable speeds, allowing it to collect hydrogen from space as it advances, and then let it perform a fusion reaction to accelerate the spacecraft with the energy generated. One gram of hydrogen atom fusion produces 630 billion joules of energy, which is 20 million times the energy of bituminous coal. Because this type of spacecraft is similar to a ramjet aircraft, it is called an interstellar ramjet spacecraft.

If the initial velocity of an interstellar ramjet is 1 kilometre, the diameter of the hydrogen collector must be hundreds of kilometres in diameter in order to collect grams of hydrogen per second.

Humans have lived on the surface of the earth for a long time and have become accustomed to bearing the earth's gravity, that is, the acceleration of gravity of 1 gram. If an interstellar ramjet flies at an acceleration of 1 gram, a person will live and work on the spacecraft with neither overweight nor weightlessness, as on the surface of the Earth.

1 gram accelerates, the speed increases very quickly, and in 2 years (the year of the earth) it can reach 97% of the speed of light, flying a distance of light years. If you go to the light-year-old Celestial Sky 5 (Crois Goldfish), after flying past the midpoint of the voyage, turn the spacecraft 180 degrees, it will slow down at 1 gram, and finally arrive at a lower speed, and return with the same procedure after 1 year, about seven or eight years (more than 20 years on Earth). For example, if it travels around the universe, the spacecraft accelerates continuously, and flies out of the galaxy in 12 years; 14 years flew through the Andromeda Galaxy; Fly a distance of 10 billion light-years in 20 years.

If the universe were spherical and had a circumference of 90 billion light-years, the spacecraft would have circled the universe 1 9 times. Since the speed of the spacecraft is very close to the speed of light, the speed effect is very significant, and it only takes 1 2 years to fly the remaining 8 9 laps and return to Earth. Of course, 90 billion years have passed on Earth.

The world is so big, there are no wonders, not to mention that in the vast universe, I think there are still elements in the universe that are not on the earth, because we still have many elements on the earth that have not been discovered by us humans, and at the same time, we humans have found a very peculiar element on Mars, which is not available on the earth, so I think there should be some elements in the universe that are not on the earth.

Yes, like the periodic table summarized by human beings, some of the latter elements are synthesized, and there may be some extremely special environments in the universe, and there are special elements for a short or long time.

There must be elements that the earth does not have, because the universe is so big, and in that far unknown depth, there must be something that we have never seen before. I believe that if we want to fully explore the universe, we will at least wait for our technology to develop before we can explore this vast universe and understand the nature of the universe. so that we can understand this universe.
