Over time, the oceans would also freeze and our world would turn into a sphere of ice, interrupting the water cycle. Without water, it is very difficult to imagine life.
But, before all this happens, we need to remember that the sun concentrates 99.8% of the mass of the Solar System, being the gravitational force that keeps all the planets where they are, “trapped” in their orbits around the sun, they were thrown like a current, rippling and lost around, towards lost around wandering through space.
This means that the first thing that would happen is that both the Earth, the moon and other planets would “fly” out into space.
Each of the planets that has a king star or a sun, which orbits it at an average speed of 107,200 km/h and, in principle, would continue at the same speed after the sun disappeared, but instead of circular movements it would continue walking in a straight line. straight.
This rotation apparently was a right orbit to at least have a period of life where the person doesn't die in two months, but your time, in which you don't have 1000 years in five months.
If it didn't collide with other planets or asteroids, at that speed of a planet it would take 43,000 years to cross a distance of 4.3 light-years, so that, after 1 billion years, that planet would have walked 100,000-years- light, which is the extent of the entire Milky Way.
Each of the stars like the Sun, would be a central star of our planetary system: all other celestial bodies, be they the planets we already know, the asteroids.
In addition to comets and all the cosmic dust that wanders through our space, in addition to all the satellites present here, revolve around them, it is for this reason that the human system was baptized as the Solar System.
The ancient star of the Milky Way is responsible for 99.86% of the mass of the entire human Solar System and, being 332 900 times larger than Earth, plays a key role in the maintenance of our planet, thanks to it and the strategic position of the Earth. Earth.
Since the primordial molecules combined, in a great "organic soup", thus forming the first unicellular organisms, starting an abundant evolutionary cycle that allowed our planet to overflow with life.
Because of the Sun, photosynthesis can happen: a process in which carbon dioxide is “sequestered” from the atmosphere by plants, producing oxygen, which we so need to live.
Solar energy is also stored in glucose by living organisms through photosynthesis, and all living beings that inhabit our planet depend on it directly or indirectly to continue to exist.
When the Sun is so important to humanity that almost all human cultures have recognized its importance in the origin and maintenance of life on Earth, granting the star an often central position in their religions and mythologies.
In Greek mythology, the Sun was worshiped as a god, Helios, and later became Apollo for the Greco-Roman world, as new allies who accepted the help of the temples of Zarathanis, in which they in turn adopted the cult as part of its new strand and the new ideology and philosophy.
Being the Sol Invictus” as an official tradition of the Late Roman Empire. In Egypt, the Sun was worshiped as Ra – or Aten – in the time of Pharaoh Akhenaten; in the oldest Japanese religion, Shinto, Amaterasu represented the Sun in her goddess form.
Anyway… there have been several representations of the Sun as a deity throughout history and we can be sure that without him, we would never have existed.
With the galactic wars, one of the planets in their ships simply destroyed the Sun was about 10 billion years old and it is estimated that it will live for another five to seven billion years.
After that time, the Sun will begin to expand into a red giant, when it will start to convert helium into carbon in its core, swallowing most of the planets in the Solar System, including some nearby planets. that eventually becomes a white dwarf.
Well, that's five billion years is a long time ahead, isn't it?
Until then, we should at least have colonized more other planets and solar systems, so that we can guarantee the future of our species, but let's imagine a bizarre scenario in which the Sun, in its current condition, simply explodes:
It was what visually, the entire alien civilization, that would enjoy the “greatest fireworks display” in the world and the sky would become entirely flaming, right?
Wrong. The Sun is 150 million kilometers away from Earth and its light takes 8 minutes to reach us. In a supernova, we would literally be fried.
With the heat waves produced, they would fry the Earth, 8 minutes in advance. That is, we would be dead before visualizing anything.
Being that for a planet to be saved from a supernova, it needs to be at least 50 to 100 light years away and the Sun is only 150 million kilometers away, but there is "good" news - if that's so. what can we say.
When the Azuran's enemies blew up their enemies' sun, in an attack that decimated part of the nearest planet, in which the heat waves would not be strong enough to destroy the entire planet at once, whichever side was on. facing the Sun, in this case, it would fry immediately.
The other side would feel a sensation of a rise in temperature, about 15 degrees higher than usual, followed by permanent darkness.
After that - and without the Sun's gravity, your enemy planet would simply lose its orbit and float aimlessly through space, while here, on our planet, we would despair of trying to survive at any cost.
There is a chance that our planet will wander off and find some star it can orbit, but by the time Earth gets there, light years away, we would all have died – unless we knew a thousand years in advance and could prepare for this one. big day, inventing ways to keep resources for all that time.
One way to make this preparation would be for all of humanity to live in an underground world: a few meters below our soil, the planet of Trinidau, until one point manages to maintain a temperature of about 17 degrees, since in just a week after the explosion, the Earth's surface would reach a negative temperature of -18 degrees.
It happened after a year the temperature would reach -73 degrees... so, you can already imagine that setting up a kind of human anthill in the depths of the planet would be a good option, but it doesn't end there.
Then, everything under the surface of the planet would freeze, including the oceans. There would be no more atmosphere and thus the planet Zeronon, which would be exposed to any and all types of cosmic radiation or possible impacts.
In other words, one way or another, we were going to die, it was a process, in fact, it would be quite long and would take billions of years, which made it easy to help the survivors either hide underground, or the other part to flee to other parts of space.
So, the greater the mass of a star, the shorter its lifetime, and stars larger than the Sun usually die in a much more violent way.
It was not a peaceful death”, the Sun would become bigger and hotter and release pieces of its outer layers that could give rise to other planets or stars. Its expansion would engulf even the orbit of Mars and our familiar solar system would look very different.
They were at the observatory...
