Won t memories turn into hope?

The current lifespan of the Earth is 4.6 billion years, and it is still unknown how long the Earth will exist in the future. Here are the references.

How long is the life span of the earth?

The Earth is speculated to have survived for 4.6 billion years, but how long will it live?

Scientists believe that if the Earth is allowed to move freely, it may exist forever, but if other external factors interfere with it, the Earth may have an end of life.

The external factor is the sun in the first place, because it is the closest planet to the earth and can have a destiny on the right earth That is to say, all the energy and power on the earth come from the sun, and once the sun has three long and two short, it is bound to affect the earth. Before the 30s of this century, people always thought that the sun would one day burn out, turn from white to orange and then to red, and finally become a dark star that was silent, but its brilliant life. In the 30s, when physicists learned the mystery of the sun's light, the situation was very different.

It turns out that the Sun's energy comes from its thermonuclear reactions, and the Sun's lifetime will pass through the gravitational contraction phase, the main-sequence star phase, the red giant phase, and the compact star phase. The main sequence phase is the period of stability of the Sun. This phase will last for 10 billion years.

At present, the sun is only halfway through and is in middle age. Once the Sun reaches the red giant stage, then the end of the Earth is coming. Of course, this is billions of years away.

Are there any other factors besides the sun's interference with the earth? Some scientists believe that the Sun may have a brother, a companion star of the Sun, which orbits the Sun day and night, and every 26 million years, turns to the closest place to the Sun"Make waves"Its strong gravitational pull will cause a large disturbance of many comets, and 1 billion comets will be on a rampage in the solar system, and the Earth and other planets will become these comets"Target"。If the mass of the comet that collides with the Earth is large enough, the consequences are unimaginable:

the extinction of light organisms and the drastic changes in ecology; Heavy landslides and earth cracks, the earth"Broken bones"。However, this solar companion star, which could bring misfortune to Earth, has not been discovered, although many scientists believe it exists.

Love doesn't have to be forever. What you have may be the best memories of your life. Because you have loved, you will not become an enemy; Because I have been hurt, I won't be friends; It can only be the most familiar strangers.

Love has been known, drunk has been drunk. The memories of love should be well collected, but the happiness in the future should be found separately. Love is a feeling, not love is also a feeling, and it is often difficult to decide whether the feeling in the heart is love or not.

Forget it, love is not as nourishing as you

You don't want to have love to nourish your heart, but

See if love chooses you ...

For the sake of your dreams, don't be shattered, let go and chase it.

Work hard for your dreams.
