I watched a documentary where it's said that light coming from the core of the sun takes thousend of years to reach the surface of the sun. Why is this so?
why this delay? since energy travels along with the lightDale said:They are actually talking about the energy carried by the light, rather than the light itself
The light gets absorbed, re emitted, and scattered a bazillion times. Each time in a random direction. The original light doesn’t travel very far at all.kent davidge said:why this delay? since energy travels along with the light
The light emitted from the core never gets to the surface. It is absorbed almost immediatelykent davidge said:otherwise I would expect the light emitted from the core to take a long time to get to the surface.

The Sun is a massive ball of gas, primarily made up of hydrogen and helium, and its core is the source of the light emitted from the Sun.
Light travels at a speed of approximately 186,282 miles per second, which means it takes about 8 minutes and 20 seconds for light from the Sun to reach Earth.
Sunlight appears to be white, but it is actually made up of all the colors of the visible spectrum. These colors combine to create white light.
The Sun produces light through a process called nuclear fusion. In the Sun's core, hydrogen atoms combine to form helium, releasing a huge amount of energy in the form of light and heat.
No, the light emitted from the Sun is not constant. The Sun goes through cycles of increased and decreased activity, which affects the amount of light and energy it emits. This is known as the solar cycle.
