What would happen if the Sun hypothetically exploded today?

Answer 1

I don't agree with others that the world would incinerate or the atmosphere would be blown away. There's no possible chance of the sun blowing up naturally, either by a supernova or gamma ray burst or anything, and since this is hypothetical, I assume you mean the sun is like a bomb and it just blows apart, completely destroying itself. The actual pieces would be traveling a lot slower than the light from the explosion and gravity, which is as fast as light. So we would see the sun explode in the sky and then eventually be enveloped in darkness, during which time Earth has begun to drift away from where the sun used to be. Remember that if the sun explodes, its no longer there to keep the planets in orbit. So, the Earth would cool way down, and probably within a week it would be too cold to live on. Oceans would literally freeze over, and the atmosphere itself may even get cold enough to turn from a gas to a liquid and then a solid, which means no more oxygen to breathe. It would not be good times.

Answer 2

One: The sunlight will no longer explode - its going to coach right into a crimson sizeable, (efficiently boiling the Earth, in all probability even burning it completely), till now at last tossing off various layers of gases (starting to be a 'planetary nebula', with the the rest fabric condensing right into a white dwarf on the grounds that this won't happen for variety of 5 Billion years. 'Homo Sapiens' have been around for decrease than a 0.5 million years ( a million/10,000 of that factor) and 'Homo Erectus' basically began strolling upright possibly 2 million years in the past (a million/2,500 of that factor), it would look no longer likely interior the excessive that persons (as we'd understand them) might nevertheless be on earth in 5 Billion years. For a technology undertaking, you're able to desire to take a rope 50 ft long - that could desire to symbolize the quantity of time left till at last the sunlight 'swallows' the earth. Now, beside that, you're able to desire to place a bean or a popcorn seed (something a pair of million/4'' in length) to symbolize the two million years of homo erectus. next to that, a bite of pencil lead (around a million/sixteen'' thick) to coach the span of homo sapiens. The thickness of a sheet of paper could be used to symbolize the time from the Egyptians to present day-day (nevertheless that is surely plenty too thick). desire this enables!

Answer 3

We would hardly notice. It would be over that fast. The only type of cosmic explosion capable of exploding the sun would probably release enough gamma radiation in the first seconds to ablate a large part of the atmosphere and superheat the surface of the earth in a few seconds. Imagine someone putting you into a microwave with hundred times the power of the one in your kitchen.

Maybe a few people in deep mine shafts would survive until the actual matter shock wave shows up a couple of hours later... but they couldn't go out without dying of radiation before they even reach the surface.

Answer 4

Whats interesting about your question is because of the speed of light,we would not be aware that it had exploded for about 7&1/2 minutes.Then it would probably extinguesh all life on Earth as the Earth flies out into the cold infinate vacume of space (hypothetically)

Answer 5

If it actually exploded, we would be incinerated.
If it didn't hit earth, it would be incredibly freezing, dark, and quite a useless planet and life.

I love the sun.. DON'T LEAVE ME SUN!

Answer 6

The world would melt and eveything would die as there was no day, it was only night!!!

All the pieces would float out into space forever and burn the universe and all the hot lava will melt us!

Answer 7

We would all die as our atmosphere would be burned off, followed by the incineration of our planet.

Bad news - this is actually due to happen.

Good news - it won't happen for about 4.5 billion years (at which time the Sun will Nova)

Don't lose any sleep over it!

Answer 8

Hypothetically the Earth & the entire inner solar system would be incinerated. Then over time our former sun would collapse into a black hole.

Answer 9

the earth and all planets in our solar system would explode or become blocks of ice. Life would cease to exist.

Answer 10

Eight minutes later, the planet Earth would be gone.
