Is an atomic explosion hotter than the sun?

During the period of peak energy output, a 1-megaton (Mt) nuclear weapon can produce temperatures of about 100 million degrees Celsius at its center, about four to five times that which occurs at the center of the Sun.

How hot is an atomic explosion?

From 0.2 to 3 seconds after detonation, the intense heat emitted from the fireball exerted powerful effects on the ground. Temperatures near the hypocenter reached 3,000 to 4,000 degrees Celsius. This heat burned human skin as far as 3.5 kilometers from the hypocenter.

What is hotter than the atomic bomb?

A hydrogen bomb, where a nuclear fission reaction compresses the fuel pellet instead, is an even more extreme version of this, producing greater temperatures than even the center of the Sun.

How bright is a nuclear blast compared to the Sun?

The Light of the Atom Bomb: In brightness, a nuclear detonation is comparable to the sun.

How many nuclear bombs equal the Sun?

We get the astonishingly huge amount of 400 trillion trillion watts. To put this into a crazy context, every second the sun produces the same energy as about a trillion 1 megaton bombs!

Sun VS. Atomic Bomb

Is the Sun just nuclear explosions?

Fortunately for life on our planet, the Sun gradually releases its nuclear energy over billions of years. The Sun is powered by the energy released when the nuclei of its hydrogen atoms slam together so hard they fuse together.

Why don't we send nuclear waste to the Sun?

The cost is too high

The cost of such a large-scale space mission is bound to be very expensive. In fact, the cost is so high that no space agency will waste time at all considering whether to send nuclear waste on Earth to the sun or the moon.

Can the Sun be stopped from exploding?

In order to save the Sun, to help it last longer than the 5 billion years it has remaining, we would need some way to stir up the Sun with a gigantic mixing spoon. To get that unburned hydrogen from the radiative and convective zones down into the core. One idea is that you could crash another star into the Sun.

What keeps the Sun burning?

The Sun survives by burning hydrogen atoms into helium atoms in its core. In fact, it burns through 600 million tons of hydrogen every second. And as the Sun's core becomes saturated with this helium, it shrinks, causing nuclear fusion reactions to speed up - which means that the Sun spits out more energy.

Will the Sun last forever?

Stars like our Sun burn for about nine or 10 billion years. So our Sun is about halfway through its life. But don't worry. It still has about 5,000,000,000—five billion—years to go.

Why doesn't the Sun explode?

Our sun isn't massive enough to trigger a stellar explosion, called a supernova, when it dies, and it will never become a black hole either. In order to create a supernova, a star needs about 10 times the mass of our sun.

How hot is a nuclear blast in Fahrenheit?

The initial fireball.

Within a few tenths of millionths of a second after detonation, the center of the warhead would reach a temperature of roughly 200 million degrees Fahrenheit (about 100 million degrees Celsius), or about four to five times the temperature at the center of the sun.

Can you survive a nuclear blast 30 miles away?

At a distance of 20-25 miles downwind, a lethal radiation dose (600 rads) would be accumulated by a person who did not find shelter within 25 minutes after the time the fallout began. At a distance of 40-45 miles, a person would have at most 3 hours after the fallout began to find shelter.

Is a nuclear bomb hotter than the core of the sun?

Temperatures of a nuclear explosion reach those in the interior of the sun, about 100,000,000° Celsius, and produce a brilliant fireball.

Can anything be hotter than the Sun?

Yes, Carys; there are lots of places in our Universe where it's much hotter than the Sun. Our Sun is a giant ball of gas that is 6000 degrees Celsius at the surface and millions of degrees in the centre.

What's worse than an atomic bomb?

But a hydrogen bomb has the potential to be 1,000 times more powerful than an atomic bomb, according to several nuclear experts. The U.S. witnessed the magnitude of a hydrogen bomb when it tested one within the country in 1954, the New York ​Times​ reported.

Is there anything on Earth as hot as the Sun?

This superheated core, says the BBC, is about as hot as the surface of the Sun. Scientists know the Earth's core, a multi-layered structure with a solid iron core spinning in a sea of liquid iron and sulfur, is hot.

Can you survive an atomic blast?

The number of casualties depends on the size of the weapon, where it's detonated, and how many people are upwind of the blast. Survivors of a nuclear attack would have about 15 minutes before sandlike radioactive particles, known as nuclear fallout, reached the ground.

How hot was the Hiroshima bomb Fahrenheit?

The Hiroshima fireball was 370 metres (1,200 ft) in diameter, with a surface temperature of 6,000 °C (10,830 °F), about the same temperature as at the surface of the sun. Near ground zero, everything flammable burst into flame.

Can fire burn in space?

Fires can't start in space itself because there is no oxygen – or indeed anything else – in a vacuum. Yet inside the confines of spacecraft, and freed from gravity, flames behave in strange and beautiful ways. They burn at cooler temperatures, in unfamiliar shapes and are powered by unusual chemistry.

Does water stop sun burn?

I can't get sunburnt when I'm in or around the water. False. Water offers minimal protection from UV radiation. About 40% of UV radiation can still reach the body 0.5 metres below the water surface.

What can the Sun not burn?

The sun does not run out of oxygen for the simple fact that it does not use oxygen to burn. The burning of the sun is not chemical combustion. It is nuclear fusion.

How much longer will the Earth last?

Four billion years from now, the increase in Earth's surface temperature will cause a runaway greenhouse effect, creating conditions more extreme than present-day Venus and heating Earth's surface enough to melt it. By that point, all life on Earth will be extinct.
