What Happens if the Sun Becomes a Black Hole? The concept of the sun transforming into a black hole appears quite frightening, but in reality, it remains a concept only present in works of fiction.
Black hole is an area in space with extreme gravitational pull in which nothing can escape.
The Sun is crucial for the survival of life on Earth. As stated by NASA, the Sun comprises roughly 99.8 percent of the mass of the solar system. Its significant mass enables the movement of all the planets around it, including Earth.
Read the article below to learn the real science is the Sun becomes a Black Hole, how gravity would change, and whether Earth could survive.
What Happens if the Sun Becomes a Black Hole?
In the event that the sun was replaced by a black hole, the Earth and the other planets in the solar system would still follow their existing orbital paths.
One might wonder how this is possible, but the strength of gravity relies on mass rather than form. Therefore, replacing the sun with a black hole having the same mass will mean that gravity remains the same.
What would happen is:
-
Earth would still orbit the black hole just as it orbits the sun now.
-
Absence of light means total darkness.
-
A significant decrease in temperatures, rendering life impossible.
-
Plant life would die out because there will be no photosynthesis.
The major difference would be absence of heat and light, not gravity. In a few weeks, the temperature on Earth will go below freezing point.
Ultimately, oceans would freeze up, and the Earth would become an icy, dead planet.
Why the Sun Won't Become a Black Hole?
The sun cannot form a black hole due to insufficient mass.
The formation of a black hole takes place mostly after a star much more massive than the sun collapses due to gravity towards the end of its life cycle. The sun cannot collapse in such a way.
This is due to the following reasons:
-
Massive stars, at least twenty times as heavy as the sun, are necessary for a black hole to form.
-
In the next 5 billion years, the sun will expand to become a red giant.
-
Later on, the sun will turn into a white dwarf, not a black hole.
According to researchers, only massive stars experience the process of collapsing that leads to the formation of a black hole.
Know Why Blackholes are so powerful?
Would we survive if the Sun turned into a black hole?
No, human beings and other living things would not survive if the Sun turned into a black hole.
Though the Earth will still be in orbit around it, without sunlight, survival is going to be extremely hard for all living organisms on Earth, since life is highly dependent on the Sun’s rays.
Some major consequences if sun becomes a black hole would be:
-
Permanent darkness on Earth
-
Extreme atmospheric cooling
-
Extinction of the food chain due to plant death
-
Unavailability of energy sources like solar power
-
Oceans and Seas would freeze instantly.
Earth could experience surface temperatures below -100 degrees Celsius within one year. It is only certain microorganisms found far below the surface that could survive.
Survival of human beings would need artificially made environments, and these have not been developed yet.
Conclusion
The sun turning into a black hole may be an intriguing thought but it is quite impossible. In case if the Sun becomes a black hole, gravity will be unchanged but life on earth would come to an end because of no heat and no light.
