is it true the sun will die out?

Question

some people told me in 30 to 40 yearsbut somebodysaid 30000 o 40000 years i know this is a stupid ?

Answer 1

No need to worry about it will be in millions and millions of years .

Answer 2

74% of the Sun's mass is hydrogen, 25% is helium, and the rest is made up of trace quantities of heavier elements, like any other star.
It generates its energy by nuclear fusion of hydrogen nuclei into helium and is in a state of hydrostatic balance, neither contracting nor expanding over time. Basically this means that the sun is a huge nuclear reactor constantly expending it's fuel.
The Sun is about halfway through its main-sequence evolution, during which nuclear fusion reactions in its core fuse hydrogen into helium. Each second, more than 4 million tonnes of matter are converted into energy within the Sun's core.
The Sun does not have enough mass to explode as a supernova. Instead, in 4-5 billion years, it will enter a red giant phase, its outer layers expanding as the hydrogen fuel in the core is consumed and the core contracts and heats up. Helium fusion will begin when the core temperature reaches around 100 MK, and will produce carbon and oxygen. While it is likely that the expansion of the outer layers of the Sun will reach the current position of Earth's orbit, recent research suggests that mass lost from the Sun earlier in its red giant phase will cause the Earth's orbit to move further out, preventing it from being engulfed. However, Earth's water will be boiled away and most of its atmosphere will escape into space.
Following the red giant phase, intense thermal pulsations will cause the Sun to throw off its outer layers, forming a planetary nebula. The only object that will remain after the outer layers are ejected is the extremely hot stellar core, which will slowly cool and fade as a white dwarf over many billions of years. This stellar evolution scenario is typical of low- to medium-mass stars.
So yes, the sun will eventually die out.

Answer 3

someday, sometime, yes it will.

it is a star, and stars die out too.

this is a fact because scientist know about stars that died out, and the sun is not special, it will follow suit.

but you need not worry, unless some large meteorite bangs in the earth, the sun will still be shining when you'll be a 150-year old person. (ie if you live to be that old!)

Answer 4

yes the sun will die out eventually. 30 to 40 years??? how can anyone even say that.

Answer 5

Only the number of years is stupid. It's millions of years.

Answer 6

Yes, it's true. One other person above is correct... In about 5 billion years.

Answer 7

yes, but 5 billion years from now,after all its hydrogen is burned

Answer 8

Every thing born must die.
so really you should see everything that way.
simply put, you will be blessed to see the sun for all your tomorrows.

Answer 9

Yes, in few million years. Don't sweat it...
