This rumor is so annoying and scientifically incorrect. The core of the sun is -739,156°C or something and it keeps the rest of the sun from getting to hot . If it got to hot, the sun would collapse in on itself, and then explode. We learn this in like 4th/5th grade guy's, come on!

It's going to run out of energy, everything will eventually.

no.

The sun is going to eventually run out of hydrogen, so it will eventually (billions of years eventually) cool and expand. In the process, it will expand large enough to envelop Earth.

I wa told by some scientists in 6th grade that it will run out of energy and explode in about 6-7 billion years.
Or something.

Fusion continually "refines" atoms at the core of the Sun (or any star for that matter.) Eventually, iron atoms will be made and that will be the death of the star. Iron is too heavy to continue fusing, and the star may explode.

if its gonna die in a time period longer than 5 billion years then why are you so concerned about it

The Sun is about halfway through life, 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, producing neutrinos and solar radiation; at this rate, the Sun will have so far converted around 100 Earth masses of matter into energy.

The Sun will spend a total of approximately 10 billion years as a main sequence star. The Sun does not have enough mass to explode as a supernova. Instead, in about 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 million kelvins and will produce carbon, entering the asymptotic giant branch phase.

Earth's fate is precarious. As a red giant, the Sun will have a maximum radius beyond the Earth's current orbit, 250 times the present radius of the Sun. However, by the time, the Sun will have lost roughly 30% of its present mass due to a stellar wind, so the orbits of the planets will move outward. If it were only for this, Earth would probably be spared, but new research suggests that Earth will be swallowed by the Sun owing to tidal interactions.

Even if Earth would escape incineration in the Sun, still all its water will be boiled away and most of its atmosphere would escape into space. In fact, even during its current life in the main sequence, the Sun is gradually becoming more luminous (about 10% every 1 billion years), and its surface temperature is slowly rising. The Sun used to be fainter in the past, which is possibly the reason why life on Earth has only existed for about 1 billion years on land. The increase in solar temperatures is such that already in about a billion years, the surface of the Earth will become too hot for liquid water to exist, ending all terrestrial life.

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.

Implying how the sun is a living thing?

Yeah. It can be destroyed tough :o

You do realize Elementary only teaches the basics, right? When you get to high school, you realize this is scientifically accurate.

Everything lives, everything dies. All stars go through a cycle and birth new ones. Whether it's from a black hole or an explosion, it will die.

The sun can turn into a black hole because it has a large mass.

The sun will not turn into a black hole, a black hole is formed when a colossal star with a mass MORE THAN 3 TIMES THAT OF THE SUNS reaches the end of it's life, get's crushed upon itself, leaving behind a compact black hole of infinity density.
