What bad thing would happen if the sun suddenly disappeared?

First of all, to say that the disappearance of the Sun is almost impossible because of the unnatural matter and energy. This is just a hypothesis designed to satisfy the curiosity of some people.

  • What would the Earth be like if the Moon suddenly disappeared?
  • What would the Earth be like if the Moon suddenly exploded?
  • Would the Earth be affected if the comet once destroyed dinosaurs hitting the Sun?
  • Why is the moon glowing?

Gravity disappears

It takes at least 8 minutes and 20 seconds for light to travel from the Sun to the Earth, so by the time the Sun disappears, we haven’t felt any change yet. But when realizing the anomaly, the inhabitants of the Earth inevitably panic, panic.

In addition, because gravitational waves disperse in space with the speed of light, the gravity of the Sun on Earth will also take 8 minutes and 20 seconds to disappear. This means that when humans realize the disappearance of the Sun, the Earth also loses its gravitational influence. Meanwhile, the Earth flies in a straight line in space according to inertia.

Other planets in our solar system are also losing their orbit

Other planets in the solar system also gradually lose their orbit and travel at the speed they are traveling around the sun multiplied by the distance between them and the sun in a straight line tangent to the orbit. After the Sun disappears these will happen after about 3.2 minutes for Mercury, Venus for about 6 minutes, 12.7 minutes for Mars, Jupiter for 43.3 minutes, 1.3 hours for for Saturn, Uranus is 2.7 hours, and it takes 4.2 hours for Neptune to detect the abnormality.

The darkness covered

The darkness covered

When the Sun disappears, from the 9th minute onwards the Earth will be in darkness. But thanks to fossil energy and electricity, cities will continue to keep their lights on, just at night time.

The stars will appear very clearly in the sky
Meanwhile, the stars will appear very clearly in the sky.

Plants do not photosynthesize

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

Trees will die if the sunlight disappears completely

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

Ancient trees can live for years in the dark

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

The temperature dropped

Without sunlight, the Earth will become cold

Without sunlight, the Earth will become cold. Initially, the average surface temperature of the Earth will fall around 14-15 degrees C. After 1 week, the temperature drops to 0 degrees C and after about 1 year later, the temperature will be minus 73 degrees Celsius.

Humans can still exist

Plants do not photosynthesize

When the Earth’s temperature drops, people will have to migrate to geothermal areas like Iceland or Yellowstone, which is “enjoying” the heat generated by the Earth itself. Anyone who cannot find shelter with warm temperatures will die within 1 year of the Sun’s disappearance.

The oceans freeze

The oceans freeze

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


Cyanobacteria can survive in the harshest conditions.

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 necessary organic matter – chemical, not photosynthesis.

An opportunity to revive the Earth

An opportunity to revive the Earth

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