What bad thing will happen if the Sun suddenly disappears?

First, it must be said that the Sun's disappearance is almost impossible because of unnatural matter and energy. This is just a hypothesis set to satisfy the curiosity of some people.

1. What will the Earth do if the Moon suddenly disappears?
2. What will the Earth do if the Moon suddenly explodes?
3. Will the Earth be affected if the comet once destroyed the dinosaurs hitting the Sun?
4. Why is the moon glowing?

Gravity disappears

It takes at least 8 minutes and 20 seconds for the light to travel from the Sun to human Earth so at the time of the Sun's disappearance, we have not felt any changes. But when realizing the abnormality, the inhabitants of the Earth inevitably became confused and panicked.

In addition, because gravitational waves disperse in space along with the speed of light, the Sun's gravity placed on Earth will also need 8 minutes and 20 seconds to disappear. This means that when people recognize the disappearance of the Sun, the Earth also loses the gravitational influence of the Sun. Meanwhile, the Earth follows a straight line in space inertia.

The other planets in the solar system also gradually lost their orbit and travel at the speed they are traveling around the Sun multiplied by the distance between them and the Sun follows a straight line tangent to the orbit. After the Sun disappeared these things will happen after about 3.2 minutes with Mercury, Venus is about 6 minutes, 12.7 minutes with Mars, Jupiter is 43.3 minutes, 1.3 hours for with Saturn, Uranus is 2.7 hours and after 4.2 hours, Hai Vuong discovered something unusual.

Night covered

When the Sun disappears, from the 9th minute onwards, the Earth will be in darkness. But thanks to fossil energy and electricity, the cities will continue to light the lights only now is all night time.

At that time, the stars will appear very clearly in the sky.

Plants do not photosynthesize

99.9% of the Earth's natural production comes from photosynthesis. Sunlight is an extremely important and indispensable element in photosynthesis.

So when the Sun disappears, photosynthesis will stop immediately. After only a few days or weeks, trees on Earth will die, except for giant trees. The amount of sugar needed to convert into living energy accumulates in giant trees that can help them survive in the dark for many years. But when the temperature of the Earth drops, they will also die due to water and sap freezing.

Trees die, causing the Earth to lose its supply of oxygen to feed living things. But because the Earth's atmosphere contains up to 6 billion kilograms of oxygen, while humans consume about 6000 billion kilograms of oxygen per year, we can still live for thousands of years.

The temperature drops

Lack of sunlight, the Earth will become cold. Initially, the average surface temperature of the Earth will fall between 14-15 degrees C. After 1 week, the temperature drops to 0 degrees Celsius and after about a year, the temperature will be minus 73 degrees C.

People can still exist

When the Earth's temperature drops, people will have to migrate to geothermal areas like Iceland or Yellowstone, where they "enjoy" the Earth's own heat output. Anyone who can't find a place with warm temperatures will die in about a year from the time the Sun disappears.

The ocean freezes  

After the Sun disappears, after 1 to 3 years all the oceans on Earth will be covered by ice. But by being protected by a thick layer of ice and kept warm by heat vents at the bottom of the ocean, liquid water can still exist deep in the ocean.

Bacteria

Within 2-3 days, most bacteria will die except for a few species that live deep in the ocean, separate from sunlight. Because bacteria produce energy by converting heat, methane (methane) and sulfur into the organic matter needed - chemically, not photosynthesis.

Opportunity to revive the Earth

When the Sun's gravity disappears, the Earth flies inertia in space in a straight line at a speed of 30km / s. Perhaps after a few billion years, when the Earth crosses the Milky Way, it might fall into orbit around a certain star, ice will melt, and the bacteria on Earth will once again. Revive people?
