What If The Sun Go Out And What If The Earth Stopped Spinning?

What would happen if the Sun went out? Even without being astronomy experts, most of us know that that big yellow thing shining in the sky is pretty important to our existence. And that without it, things down here on Earth would be rather cold and dark. However, we were curious to understand what might happen if our giant source of heat and light suddenly vanished from the sky.
Without neglecting to ask a final question about the consequences of a cosmic braking…
But this I have just described to you is the sequence of events that will lead to its natural death. Let’s instead invent a thought experiment, and try to imagine that the Sun would suddenly go out, like a light bulb — right at this moment!
What would happen? After how long would we notice it?

At the speed of 300,000 km per second, light takes about 8.3 minutes to cover the distance between the Sun and Earth, which is about 149.6 million kilometers. So from the moment the sun disappears, it will be a little more than 8 minutes before we know visually what has really happened.
An illusory security that also relates to another famous thought experiment… that of asking: What would happen if the Earth stopped rotating?
Have you ever thought about the possible consequences for life on the planet if the Earth suddenly stopped rotating around its axis and came to a complete halt?
Well. Before we start talking about the disasters you are already surely imagining, it is only fair to point out that right now the Earth is spinning on itself with an angular velocity of 15° per hour, which corresponds at the equator to a speed of about 1670 km per hour.
