So the Sun is out and we have light for 8 more minutes, if we wouldn't be aware of the fact that the Sun "died", would we notice it, before the light goes off?

And what about the last 8 minutes? Any changes in the temperature, sunlight etc.?

Since nothing can travel faster than light, if the light from the event hasn't reached us, the event has not happened yet. Einstein showed how the limitations imposed by the speed of light affect the concept of simultaneity, and that each location has its own "now". This intrinsic entangling of time and space is why you see references to "space-time". The universe that you can see is all happening right now, the fact that the light took a billion years (or eight minutes) to get here notwithstanding.

Personally since everything travels at the speed of light in this instance I would say yes. It would take at least 8 minutes for us to see the effects of whatever happens to the sun in terms of it dying. But, the suns death is a gradual process that is going to take billions of years. Trust and believe before the sun's lights just goes out the sun will swell to an enormous size obliterating the Earth and the inner planets in the process and then it will shrink to a white dwarf still emitting light

In the 8 minutes where the Sun stops giving out life, we will be dead anyway as we will have been engulfed by its "Red Giant" stage and be scorched to nothing, but we would see no difference because it takes 8 minutes for light to reach us from the Sun, so we will have no natural light (meaning it will be night time all the time) 8 minutes after the Sun stops giving out light

We would not notice any changes until the eight minutes is up. Nothing can travel faster than the speed of light, so therefore, we could not feel or see any changes for eight minutes. Some people speculate over whether we would feel gravitational effects of the sun dying instantaneously (faster than light), but Einstein said even gravity does not travel faster than light.

So -- we would not know that the sun died until eight minutes after the fact.

nothing will change for us until after 8 minutes. The first thing we would notice is darkness. Then temperature change and all the other things that would follow. Light travels the fastest in the universe so we would see it go out first.

OH MY GOD!

The fuel depletion of a star takes millions of years to happen.

Long before it start the radiation from the outburst of solar flares will shut down the magnetic field of Earth.

The ultraviolet light and radiation level will increase sterilizing this planet of all living forms.

Over the next 10,000 years the Sun will expand as it becomes a RED GIANT engulfing Mercury, Venus and EARTH.

Nothing but a burnt out rock will remain.

100,000 years after that it will beging to shrink until it becomes a white dwarf. How it will remain until the end of times.

It will never go dark.

If the sun died, it would have previously turned into a red giant, which means we would have been fried a million years previous to it becoming a red dwarf. So it's not like we'd just be hanging out here on Earth and then the Sun stopped shining. But I like your theory, and it would be fun to see.

Who told you about "last 8 minutes" ?

We would see no changes

We would notice nothing unusual until we reach the event horizon.
