Is the earth absolutely safe, is the earth safe

It's relatively safe, and it's definitely not safe, but do we have any other options?

There are so many absolutes besides that motion is absolute. Danger is potential, this is normal, when asking this question, it is better to work hard, enjoy life well, a person's life is only a few decades in a hurry, just let it be.

Hello, glad to answer for you. Earth is in a safe corner of the solar system. This is because we are currently losing money and there is no way to really leave the solar system, including sending some machinery and equipment out of the solar system.

And according to the information transmitted by the two probes of the Explorer series, the solar system is far larger than we think. So we can't really conclude that the entire solar system is safe, there are no black holes, no nebulae and other matter. But now safety does not mean always safe, the hot reflection of the small wrecking ball let us all know that the final fate of the sun will cause us disasters, but compared to this, there is another disaster that may be closer to the earth, that is, the disaster from the moon.

We all know that the "little brother" of the moon is breaking away from the control of the earth, and it is likely that Sun will become a planet of the same level as the earth in the future. I hope my answer helps you.

<> for example, there are about 80,000 known near-Earth objects (NEOs), that is, blocks of "space rocks" or asteroids-ranging with diameters ranging from 1 meter to 1 km, like the Moon, that share their orbit with the Earth and are therefore constantly approaching the United States and, therefore, repeatedly in positions where they may collide with the Earth.

Near-Earth objects do not include the approximately 31 million main-belt asteroids orbiting the Sun between Mars and Jupiter — 750,000 of which are well over 1 kilometer in diameter — whose orbits cross the Earth at a much lower frequency.

However, unlike the Moon, NEOs do not orbit the Earth, but rather act like a "column" with the Earth orbiting the Sun, except that many are "Earth crossers" whose eccentric orbits often intercept the Earth's orbit. About 15,000 tons of meteors enter the Earth's gravitational field in the form of meteors every year (that's 41 tons per day!). Most meteorites are relatively small in size and completely burn up due to friction with the Earth's atmosphere before reaching the surface as meteorites.

Still, every day at least one meteorite with a diameter of 400 mm or more passes through the atmosphere to reach the Earth's surface, which, along with all the smaller dust and space debris, actually adds about 100 tons to the weight of the Earth. Yes, you read that right, 100 tons of space debris are dumped on Earth every day of the year – and not humans!

In the early days of life on Earth – about 4 billion years ago – the number was much higher, and it was actually all the debris that turned the Earth from a relatively small "space rock" into what it is today. Of course, as more and more fall on Earth, that means there is less and less left to land on – which is why Earth is much lower (and safer for us) now.

Safe. Because the Earth's environment is now very stable and there are no external dangers, the Earth is safe now.

It's safe for now, because it's still able to sustain our humans all over the world, so that our humans all over the world can spend every day on it unharmed.

I think the earth is still relatively safe now. Because people are protecting the environment of the planet. I believe that the earth will get better and better in the future.

No matter who it is, there will always be a day when the earth will be destroyed, it's just a matter of time or time, because:

Dialectics holds that everything in the universe has a process of occurrence, development and disappearance, including human beings, the earth, and the solar system. Nature created a brilliant flower of life, and finally brutally killed it, this is the law of the universe, and no one can change it! A great man once said that when the end of mankind comes, the whole world will celebrate the victory of dialectics!

Life is lost here, extinct, but reborn in another place where conditions are right to begin a new evolutionary process. It can be said that the end of life, like the beginning (birth) of life, is not subject to people's subjective will. Life in the universe is in an endless, cyclical, and never-ending process.

The end of the world is in line with dialectics, it is not subject to people's subjective will, and no one can stop it, but when will the end of the world come, and in what form? Did it happen in 2012 or so-and-so? No one can tell, but it's certain that this day will come sooner or later!

It's a pity that you and I probably can't wait for this day haha!

Finally, one thing is certain, with the increasing destruction of the natural ecological environment on the earth, the natural disasters faced by human beings in the future will become more frequent and more serious, and even threaten the survival of human beings! Humanity must not take this seriously!

Oh, it's hard to say. Now what is not dangerous, what food safety, traffic safety ......It's a lot, and it's not surprising that the earth is in danger right now. You say yes, right?

We can't predict the future, but you can't wait for the end of the world, although there will be an end of the world.

It should be no, oh, normal life, life should be positive, not negative,

Yes, the earth is in a very dangerous situation.

But we don't have a choice, do we? At least now humanity is not in a position to make any other choice.

So, we want the planet to be able to get through the danger.

1. The danger of extraterrestrial creatures.

2. The danger of human nuclear weapons.

3. The danger of terrorism.

4. The danger of destruction of the earth's environment.

5. The danger of planets and other objects hitting the earth.

Wait a minute. There are many dangers, and I wish humanity and the planet better and better.

The earth is subjected toSurrounding Jupiter and other asteroids, meteoritesThe winding is protected in an orderly manner.

In the millions of years that humans have appeared on the earth, the development of human beings can be explained in four words, we can say that the earth is a very safe planet, and human beings include everything on earth. After discovering the mysteries of the universe, scientists discovered that there are three obstacles around the Earth. Thanks to their supporters, Earth can become the most special planet.

The first is Jupiter, which is naturally known as the protector of the Earth. Jupiter is large, and there are many asteroids and meteorites in space. The planet is in flight, covering a large number of Jupiter, and all this damage will fly towards Jupiter and will not threaten the safety of the Earth.

If this asteroid escaped from the Jupiter Cluster and escaped the Earth's second barrier, it would be the Moon, which is often ignored by everyone. This does not mean that the moon is too small to be a planet like Earth's satellites. Where there are many craters on the Moon, a shield can be seen, which is evidence that the Moon protects the Earth, and the asteroid that can escape from these two natural barriers and continue to fly towards the Earth has almost become fragments.

The Earth will do so much damage, not to mention the Earth's third barrier, the thick atmosphere.

The height of the Earth's atmosphere is more than 1000 meters. Since many asteroids and meteorites penetrate the atmosphere, they will create intense friction that will heat up and burn the asteroid, making it less harmful to Earth.

The Earth has not been greatly attacked in these hundreds of millions, which is why the Earth is so safe. With these barriers, the Earth will remain safe for many years to come, and will be even stronger when technology advances more powerfully in the future.

Because the constant magnetic field in the universe can control each other.

I think this must be because the Earth is protected by extraterrestrial life.

He was not materially protected. Rather, it is because he has the ability to protect himself.

I think this is still amazing, and the current level of science cannot confirm it.

The earth provides space and places for human survival and development; Earth is the only known planet with advanced intelligent life; The earth's resources and energy are indispensable for human survival and development; The earth is currently the only natural environment in which human beings can live normally.

In the solar system, the Earth is about 100 million kilometers away from the sun, not far away, not close, not hot. There is a thick atmosphere on Earth that protects the planet. There is also water on Earth that life is indispensed without.

Therefore, the earth can become the only living planet in the solar system, and the only home for mankind!

The physical and chemical environment of the earth provides opportunities for the evolution of life, ensuring the birth, evolution and development of human beings. So, for the time being, the Earth is not only the home of human survival, but the only one.

Because the earth is so important to us. Without the Earth, what would humanity do? At least now, the Earth is better than all the planets that have been discovered, more suitable for human life than any other planet, at least, she is our first home, our mother, and why are we called earthlings?

Think about it, my friend. We need the planet! The earth is very important to humanity!

So, please don't let the earth be destroyed, please imagine what the earth will be like in a few hundred or thousands of years if human beings continue to destroy the environment with impunity, isn't it just a ruin? One might ask, friends, but who is the one who caused this ruin? Isn't it ourselves yet?

So, please protect the planet! Because, the earth is the home of human survival!

1. The sun is relatively stable and can provide energy to the earth for a long time 2, the environment is relatively safe, there are not too many asteroids 3, and the existence of the atmosphere greatly reduces the impact of foreign celestial bodies on the earth.

Because you look at it from the perspective of human beings, after all, the life span of a single human individual is limited, and the history of the development of human civilization is also very limited, so there is such an illusion. If you look at it on the scale of the universe, or to a lesser extent, from the perspective of the entire solar system, the interior of the solar system is not very safe. Not only have outsiders invaded the solar system, but also the asteroid belt between Mars and Jupiter and the Kuiper belt around Neptune are mostly irregular celestial bodies, and one may run out one day due to gravitational disturbances, and I don't know if it will crash into Jupiter, Mars, or other stars.

Only outsiders have broken into the solar system, and the asteroid belt between Mars and Jupiter and the Kuiper belt around Neptune.

This is mainly due to the fact that the earth has three major guarantees, which have protected the earth layer by layer, and perfectly protected the earth, so perfect that people can't believe it, and even suspect that the earth is deliberately protected. The first is Jupiter, which blocks most of the threats to Earth. But it's not perfect, because there will always be fish that slip through the net and are not intercepted by Jupiter.

For those who slipped through the net, the moon began to play its role, and the dense impact craters of different sizes we see on the far side of the moon are actually the objects in the asteroid belt that escaped and evaded the interception of Jupiter, and finally were intercepted by the moon when they hit the earth.

From the perspective of the entire solar system, the interior of the solar system is not very safe.

The sun is relatively stable and can provide energy to the earth for a long time.

Because there are many celestial bodies protecting the Earth nearby.

Because the Earth is located in an extremely rare habitable zone in the universe.

Because a lot of meteorites were intercepted by Jupiter.

Jupiter will protect the Earth, and then there will be a vapor layer to protect it.

In a nutshell: the earth itself is not dangerous, only human beings are at risk. Because humans can change the earth, causing all kinds of pollution, changing the weather, destroying water resources, and so on.

The destruction of arable land, the reduction of land for crops, and the extraction of various resources such as coal, oil, natural gas, etc., will cause damage to the planet year after year. Volcanoes, tsunamis, etc. do not occur very often, and the incidence of large-scale natural disasters is also low, as long as human beings treat the earth well, the earth will not retaliate against human beings.
