Why does sun never run out of heat energy?

"Never" is a big word... The Sun has shone for a long time, and it will continue shining for a long time, but it will eventually run out of fuel."Never" is a big word...

What is one problem with fuel cell cars?

one problem with fuel cell cars is that if they run on solar energy then if theres no sun that day it won't have the power to reverse it into energy and run the car with the sun energy needed!


How do scientist estimate the temperature of the sun?

We don't need to estimate it, we can measure it (at least the surface temperature) using the cavity radiation equation and experimental observation of the solar spectrum.


Will the sun shine forever why or why not?

No, the sun will not shine forever. The sun is a star that will eventually run out of fuel and expand into a red giant before collapsing into a white dwarf. This process will last billions of years, but eventually the sun will no longer be able to sustain nuclear fusion and will fade away.


Why do sun like stars turn into white dwarfs?

It is because it collapses after it has run out of "fuel".

The energy source in this case is the Sun. Yes, the Sun will run out of fuel eventually, but it is expected to continue shining for about 5 billion years or so.


What happens to stars bigger than then the sun?

When they run out of fuel they collapse and become black holes.


When is the predicted date of when the sun will burn out?

Scientists estimate that the sun will run out of fuel and expand into a red giant in about 5 billion years. After this stage, it will shed its outer layers and eventually become a white dwarf, leaving behind a planetary nebula.
