When the Sun explodes, will there be millions of years of light, escaping all at once?

Answer 1

Our sun will not explode.
In approx. 5 billion years it will become a red drawf and expand past the earth's orbit.

A star must be much larger to nova, or explode.

Answer 2

The sun wont explode. It will expand in size dramatically starting about 4 billion years from now and puff off its outer layers before contracting to a white dwarf. In the process it will give off a great deal of energy in the form of heat, radiation, and light but it would not escape all at once and it would not be correct to think of it as being millions of years of light, although for several million years the energy given off per second will be a lot higher than at present..

Answer 3

I think you're just a bit confused.

First, the sun will not explode - its not massive enough. In a few billion years it will start to expand and become a red giant (no explosion), then a few more billion years and it will puff off its outer atmosphere (again, no explosion) and then start to cool off.

Second, when a star explodes in a supernova, it instantly fuses the remaining hydrogen and helium fuel (and all the other fusable elements it has created in its core) in an intense burst of light, heat, and high-energy radiation (xrays and gamma rays). The explosion takes a few seconds to start, then will continue to glow for weeks or months (if we could see it) until it fades, leaving an expanding sphere of debris and either a neutron star or black hole (or possibly nothing) behind.

So since its so bright, you might say that a number of years of light are released (you might say that, but scientists wouldn't). But there is no way to relate the amount of light in a supernova to a specific number of years - they just don't correlate with each other.

Answer 4

If the Sun explodes ...................... the escaping light would be the very LEAST of your problems : )

Answer 5

no, when the sun explodes its going to combine with hydrogen present in it and that will be more stable source of energy , so there will be light and nothign escaping

cheers!!!!!!!!!

Answer 6

Light is not measured in years. Your statement makes no sense.

If you're thinking of a "light-year", that is a measurement of DISTANCE. It is the distance light travels in one year. Here's the conversion factor:

1 light-year = 5,878,499,810,000 miles

Answer 7

use a match (parental control if under age please) the match gives off heat when not lite (radiant) when lit a large volume is given off at once... this is many times the amount given off by the match not lite... rough example but you should see my point.
