Why are scientists looking for planets with hydrogen in their atmospheres? Could it be that aliens b

The reason why scientists are looking for planets with hydrogen in their atmospheres is not because aliens breathe hydrogen, but because scientists guess that they breathe in a unique way, and more importantly, the properties of hydrogen itself, one is that the quality of hydrogen itself is very lowIf there is a large amount of hydrogen on a planet, it means that the mass of the planet is very large, and scientists speculate that the mass of a planet with a large amount of hydrogen is about 2 to 10 times that of the Earth; The second is that hydrogen in sufficient concentrations can also act as a greenhouse gasThis means that they can maintain a certain temperature on the planet and, if ideal, liquid water. <>

In recent years, scientists have moved away from studying matter on Earth and are focusing their attention on the solar system and beyond. With the increasing number of known planets, as well as the ** sent back by the Mars probe in the United States, people have more reason to believe that in addition to humans, there may be other life in the universe, although this is just a guess, but the probability is still very high, since there may be life, it will also give birth to a problem, if the breathing mode and respiratory substances of creatures on other planets are not the same as humans? <>

To be honest, this possibility is not impossible, and some people have put forward such a conjecture that aliens exist in the form of dark matterAlthough this statement is groundless, judging from the various clues that human beings currently have, there is such a possibility. Since it is an exploration of the unknown, the first thing to do is to dare to guess, of course, this speculation is not imaginary, but has a certain basis, taking scientists to suggest the detection of planets with high hydrogen content as an example, in fact, there are many microorganisms on the earth that are metabolizing hydrogen for the continuation of life. <>

This shows that the conjectures of scientists are very well-founded, and even if they are ultimately inconclusive, they have also increased the rate of human exploration of the universe.

Because scientists think that aliens are very likely to breathe hydrogen, aliens are indeed very likely to breathe hydrogen.

Because the main component of water is hydrogen, where there is hydrogen, there will be water, then it means that the planet is alive.

Human beings rely on oxygen to survive, but it does not mean that all extraterrestrial civilizations in the universe and space can rely on oxygen. Studies have shown that hydrogen in sufficient concentrations can act as a greenhouse gas. This keeps the planet's surface warm enough to maintain liquid water, which is the source of life.

Although the earth does not produce a large amount of hydrogen, there is still hydrogen, and hydrogen is the lightest gas, so there is a possibility that hydrogen is too light, and the attraction of the earth cannot restrain it, so some of the hydrogen slips into outer space.

To put it more simply, if an object moving on a planet moves at a certain speed, then it can get rid of the gravitational pull of the planet and run into space, which is called escape velocity. The escape velocity on Earth is about kilometers and seconds. All gas molecules are doing random thermal motion, and with respect to any gas molecule, there is an escape velocity, and the smaller the molecular weight, the lower this velocity.

Hydrogen has a smaller molecular weight, so it also has a lower escape velocity. When hydrogen reaches the upper part of the atmosphere, there are always some hydrogen molecules that move faster than the heat, so they are the first to flee the earth. In addition, due to radiation, disturbance and other factors, once its thermal motion speed exceeds the escape velocity, it will also leave the earth one after another.

So, in the Earth's atmosphere, there is almost no hydrogen.

We don't know what kind of gas aliens breathe, but under the existing scientific and technological research, oxygen is an indispensable thing for living matter, and it has become the mainstream idea now.

Because oxygen is produced by photosynthesis, if there is life on the planet, then a lot of oxygen may be produced. If there was no life on the planet, a large amount of oxygen would not exist. Hydrogen is too light to float on the planet and needs oxygen to oxidize it and turn into water.

So oxygen is the basis for the existence of life on the planet.

Because oxygen is an indispensable gas for living organisms, once you leave oxygen, you will feel extremely uncomfortable in your heart for a minute, and you will die directly, and it is not possible to confirm that aliens inhale hydrogen for the time being.

Because scientists have discovered that where there is life, there will be a lot of oxygen, so they feel that where there is oxygen, it is suitable for life. And what aliens rely on to sustain life has not yet been discovered, and the evidence supporting the existence of aliens is also very ethereal.

Scientists use the presence or absence of oxygen to determine whether there is life on this planet, so can't aliens rely on hydrogen and helium to breathe? In fact, this topic seems very convincing, the universe is so big, why do we have to breathe oxygen like humans, need water and carbohydrates to replenish energy, can't we breathe hydrogen, helium or even nitrogen? Let's take a look at the possibility?

How many possible lives are there?

Don't think that you think that there are other types of life in the universe, because scientists have more brains than you, otherwise why wouldn't you become scientists? So how many of the possible life types are there?

Carbon-based life. 1.Carbon-based water-based life, a type of life with carbon as the core element and water as the medium.

2.Carbon-based amino life, a type of life with carbon as the core element and ammonia as the medium.

3.Boron-boron-based hydrogen fluoride-based life, with boron as the core element and hydrogen fluoride as the medium, is a type of life.

Silicon-based life is a type of life with silicon as the core element and silane as the medium.

Life in the form of energy exists in the form of an internal quantity (without substance), such as the type of life in the plasma state.

Artificial types of life do not do metabolism of bioelectric energy or quantum computers as carriers of organisms.

Life in the form of electromagnetic waves and information.

What types of life have been discovered so far?

Of course, you are not mistaken, we have only found carbon-based life on Earth, not any type of life on the Moon or Mars, and the farther depths of the universe, except for some organic molecules, are blank for you to discover!

Water is the medium of exocarbon-based life - is very critical, so we will be very interested in the existence of liquid water when searching for exoplanets, but we are not particularly concerned about the existence of oxygen, why is this so, and is oxygen not a necessary gas for life? In fact, there are many lives on the earth that can survive without oxygen, such as E. coli can be aerobic or anaerobic (fermentation to obtain energy), and lactic acid bacteria are aerobic and anaerobic are mainly fermented! But one thing to point out is that as long as there is water, oxygen will be present, because of the presence of liquid water, which will evaporate in large quantities in warm climates, and photolysis in the upper atmosphere will allow hydrogen to escape and leave oxygen behind, albeit in very small amounts, but in billions of years it will be a very significant amount!

Because organisms must absorb oxygen if they want to survive.

Life in the form of energy.

A type of life that exists in an internal form (without a substance), such as in the plasma state, does not require oxygen to survive.

According to logical reasoning, in the infinite universe, the life forms of aliens must also be diverse, and they are not necessarily the same as us earthlings.

Carbon-based water-based life, a type of life with carbon as the core element and water as the medium.

It's more reasonable to be more predominantly oxygen, and other gases are really a bit hard to explain.

There are other life forms that do not survive on oxygen.

Life should be viewed in terms of the presence or absence of water, oxygen is secondary.

This may be the difference between the creatures.

Breathe oxygen and use water as the solvent for life.
