what would it look like if the sun exploded

What would happen, hypothetically, if a black hole appeared out of nowhere next to Earth? … The edge of the Earth closest to the black hole would feel a much stronger force than the far side. As such, the doom of the entire planet would be at hand. We would be pulled apart.

Will Earth end up in a black hole?

Will Earth be swallowed by a black hole? Absolutely not. While a black hole does have an immense gravitational field, they are only “dangerous” if you get very close to them. … It would get very dark of course and very cold, but the black hole’s gravity at our distance from it would not be a concern.

How cold would Earth be without the sun?

And without sunlight, the Earth would get very, very cold. Earth’s surface temperature now averages about 57 degrees Fahrenheit, but by the end of the first week without the sun, the average surface temperature would be below the freezing point.

What would happen if the sun disappeared for 1 minute?

As soon as the last of the sun’s light reached us – eight-and-a-half minutes after the sun itself disappeared – the sun would blink out and night would fall over the entire Earth. Not until that instant would Earth sail off in a straight line into space. … But then the night sky would begin to change.

What would happen if there was no Jupiter?

There would be minor changes in the planets’ orbits about the Sun, but very little else. However, Jupiter does a great job of shepherding and absorbing small objects in the Solar System. With Jupiter gone, the main effect on Earth would be an increase in the rate of impacts from asteroids and other space flotsam.

Has anyone went to the black hole?

But if you’re going to try it, you need to know this one small catch. Scientists say humans could indeed enter a black hole to study it. Of course, the human in question couldn’t report their findings—or ever come back.

Would entering a black hole hurt?

When you start feeling pain depends on the size of the black hole. … If you’re falling into a stellar black hole, you’ll start feeling uncomfortable within 6,000 kilometers (3,728 miles) of the center, long before you cross the horizon [source: Bunn]. Either way, spaghettification leads to a painful conclusion.

What is a white black hole?

A black hole is one prediction of Einstein’s theory of general relativity. Another is known as a white hole, which is like a black hole in reverse: Whereas nothing can escape from a black hole’s event horizon, nothing can enter a white hole’s event horizon.

What if Earth had 2 moons?

If Earth had two moons, it would be catastrophic. An extra moon would lead to larger tides and wipe out major cities like New York and Singapore. The extra pull of the moons would also slow down the Earth’s rotation, causing the day to get longer.

Will Moon ever crash into Earth?

Exceptionally unlikely.” But for an object to knock the Moon off its orbit, it would have to be “big enough to hit the Moon at the right speed at the right angle,” says Byrne. … So the Moon’s orbit is getting further away from Earth, not closer, and certainly not on a collision course with our planet.

What happens if the Moon crashed into Earth?

With the Moon coming closer, Earth’s rotation would speed up. Our days would become shorter and shorter. Global temperatures would go down, nobody would worry about climate change anymore. Unless asteroids burned the Earth to a crisp.

How long would it take for the world to freeze if the sun went out?

In the best case, the average temperature drops to 32 degrees Fahrenheit in about 400 days, and to zero degrees Fahrenheit in 879 days. These averages, however, include the oceans, and the heat retained there will largely stay there, not doing us much good.

Why can we not live without the sun?

Without the sun there would be no vegetation on earth, because every plant needs light to live and grow. The sun even enables them to generate oxygen by means of photosynthesis, which humans and animals need to breathe. The earth’s position in the solar system is optimal for the development of life.

How cold is space?

about -455 degrees Fahrenheit
Far outside our solar system and out past the distant reachers of our galaxy—in the vast nothingness of space—the distance between gas and dust particles grows, limiting their ability to transfer heat. Temperatures in these vacuous regions can plummet to about -455 degrees Fahrenheit (2.7 kelvin).Sep 25, 2020
