The sun will eventually lose around one-third of its total mass throughout the course of its lifetime. Its gravitational pull on the Earth lessens as it loses mass, despite the fact that it continues to increase in size. The Earth is progressively receding in its distance from the sun. Heat from the rising sun will burn away our seas and atmosphere, and our planet will be completely devoid of all life as a result.

What would happen if the sun ran out of energy?
The sun will run out of energy in around 5 billion years, causing the solar system to undergo significant changes. The oceans will be baked to a crisp. When the fuel source is depleted, the sun will begin to expand at an alarming rate. As it evolves into what astronomers refer to as a red giant, its outer layers will spread until they envelop a large portion of the solar system.
How long will it take for the sun to run out of fuel?
In around 5 billion years, the hydrogen in the Sun’s core will be depleted, and the sun will no longer have enough fuel for nuclear fusion to continue functioning. As a result, the Sun will cease to shine in around 5 billion years.
What if the Sun died?
When the Sun’s hydrogen reserves are depleted, it will erupt into a red giant, which will consume Venus and Mercury in the process. The Earth will be reduced to a burnt, dead rock, having lost its atmosphere and had its seas cooked away. There is a lot that can happen in the next 5 billion years, even if the Sun will not become a red giant for another 5 billion years.
How many years until the world ends?
By that time, all life on the planet will have gone extinct. Most likely, the planet will be absorbed by the Sun in around 7.5 billion years, once the star has entered the red giant phase and grown beyond the planet’s present orbit, according to current estimates.
Can we fuel the Sun?
The only fuel the Sun can utilize for fusion is contained within its core, which occupies only 0.8 percent of the Sun’s volume and accounts for only 34 percent of its mass. When it has used up all of the hydrogen in its core, it will blow off its outer layers into space, where it will eventually collapse and become a white dwarf. One possibility is that you may collide with another star and destroy it.
What will happen if the Sun explodes?
If the Sun bursts, all human and plant life on Earth will perish at some point in the future. Scientists predict that the sun will gradually get colder and larger, and that it will eventually become a red giant. The planet will most certainly engulf Mercury, Venus, and Earth as it begins to grow, and these three planets will be destroyed in an instant.
Will the Sun burn out?
The Sun will run out of hydrogen in around 5.5 billion years and will begin expanding as it consumes helium. It will transition from being a yellow giant to a red giant, extending beyond the orbit of Mars and vaporizing the whole planet, including the atoms that make up your body and mind.
How long will humans last?
In accordance with J. Richard Gott’s formulation of the contentious Doomsday argument, which asserts that we have likely already lived through half the span of human history, humanity has a 95 percent chance of becoming extinct in 7,800,000 years.
Can we survive without sun?
Everything from plants to creatures that rely on plants for nourishment, including people, would perish if the planet were to go extinct due to global warming. Some humans may be able to survive on a sunless Earth for several days, weeks, months or even years if they are resourceful, but life on Earth without the Sun would eventually prove to be difficult to sustain.
What if the Sun disappeared for 5 seconds?
If the Sun were to suddenly vanish, the Earth (and all other objects in the Solar System) would continue their forward travel in a straight line into space, rather than continuing their almost-circular orbits as they do now. This indicates that the Earth would be traveling at around 30 kilometers per second towards the stars (67,000mph).
How Many People Can Earth Support?
The average American consumes around 9.7 hectares of land. Simply based on this information, the Earth can support at most one-fifth of the current population (1.5 billion people) at a quality of living comparable to that in the United States. Water is essential.
How old is the Earth?
On average, Earth has been around for 4.54 billion years, plus or minus around 50 million years. Scientists have combed the planet in quest of the oldest rocks that can be radiometrically dated, but have come up empty-handed. They uncovered rocks that were approximately 4.03 billion years old in northern Canada.
