The Sun which is considered as a source of heat and energy is actually a star in the center of the Solar System, It looks like, a perfect ball of plasma that is too much hot because of nuclear fusion reaction. We can see things just because of sunlight also the fruits we are eating are just because of the sun because plants perform photosynthesis in sunlight. The temperature of the earth is bearable just because of the sun. But have you ever thought that what happens when the sun disappears? You can't think that what will happen if the sun disappears for a second. So in this article, you will get the answer to this question.
What if the Sun Suddenly Disappeared?
There is a limit to the speed at which information is transmitted in this universe, which is commonly called the speed of light. This speed is about 300,000 kilometers per second. Which is denoted by c. But what if this speed of information transmission was not fixed? The news of the destruction of a distant planet might have reached us first and news of the formation of the new planet may reach us later. Therefore, there is a limit to the speed at which information can be transmitted. From which we get the knowledge about formation to the step by step, or gradual, end of the star in the order in which those events take place. So not only photons will travel at the speed of light, which are small packets of light and massless particles, but also force carriers of strong nuclear force massless, gluons, and gravitational waves.

What Will Happen to Planets If Sun Disappeared?
If our sun suddenly disappears somewhere, the first to know about the disappearance of the sun will be Mercury, the closest planet to the sun. Then Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune will find out that the sun has disappeared.
What Will Happen to Earth if Sun Disappeared?
When the sun disappears, the photons emitting from the sun will travel at a speed of 300,000 kilometers per second and reach us in eight minutes and twenty-one seconds (8 Minutes and 21 Seconds) after the sun disappears, the whole earth will be plunged into darkness. The birds that used to find their way because of the sun will get lost. In the absence of sunlight, photosynthesis in plants will stop. The gravitational waves of the sun will be able to feel the earth for only eight minutes and twenty-one seconds after the disappearance of the sun, after which the earth will start traveling in a straight line on an unknown path, forming a tangent in its spherical orbit around the sun. Just like when a stone tied to a rope is rotated, when the rope breaks or the rope is released, the stone starts moving in a straight path by forming a tangent in its circular orbit.
What Would Happen to Humans if the Sun Disappeared?
Humans will be calm for some time because of the heat absorbed by the earth from the sun. But this will not always be the same. Since the sun, the source of heat, disappear the earth will gradually cool down. Oceans, glaciers, lakes will all begin to turn to ice. The temperature will continue to fall. People will dig the ground and seek refuge in its warm layers. But with the passage of time, this method will not work and in the end, no human being, animal, beast, the bird will remain. on earth.
If the Sun disappeared Would we Freeze?
A common question which is asked by millions of people is that will we freeze without the sun? So just Like, If we put a cup of Coffee or Tea in Refrigerator then it will not gonna freeze instantly, rather it will take some time to freeze. So just like this, the Earth will also not gonna Freeze instantly the earth will remain hotter for some time without the sun. But the Temperature of Earth will fall below 0°F within a week and it will gradually fall and after a year the possible temperature of the earth without sun will be -100°F. The Top layers of the oceans will freeze but below the top layer it prevent itself from freezing for thousands of years and humans can live in submarines in the warm layers of oceans for a long time.
But don't be afraid, the sun is not disappearing anywhere. This is just a possible scenario that has nothing to do with reality.
