We would all be killed in the supernova explosion that created the pulsar out of our Sun. The Earth itself would be vaporized. Any returning space travelers would be fried by the intense pulses of gamma radiation that give the "pulsar" or "pulsing gamma ray source" its name.

However, this cannot happen - because our Sun isn't nearly massive enough to go supernova.

Earth is a planet, not a star; it can never be a pulsar.

For an excellent description of what life might be like on the surface of a pulsar, read the boon "Dragon's Egg" by Dr. Robert Forward.

What would happen if the sun was replaced by R136a1?

R136a1's heat would probably vaporize all of the planets.


What would happen if Neptune came closer to the sun?

it would blow up!


What would happen if you put pure water in the sun?

it melts


What would happen to Earth if the sun was replaced by Alpha Centauri A?

It's a similar star in most respects to our Sun, slightly larger, but the increase in size, would probably be offset by an increase in revolution. So probably not much. It might be a little warmer and the years should be shorter, but in all other aspects - life would go on as normal.


What would happen to the Earth's oceans if the earth was closer to the sun?

oceans would dry

What would happen if Betelgeuse was your solar system star?

If the star Betelgeuse replaced the Sun, most planets will be inside the star, even Jupiter. It would outshine the Sun like the Sun outshines the Moon.


Could the sun be a pulsar?

No. A pulsar contains the mass of the Sun, squeezed into a ball 20km (12 1/2 miles) across


What will be the last stage of life for your sun?

A Pulsar


Are pulsar star found in the solar system?

No. There is only one star in our Solar System, the Sun and it is not a pulsar.


Did the sun form out of a pulsar?

no, it formed from a nebula, then condensed


If the Sun were replaced by a star with twice as much mass what would happen to the gravitational force between Earth and the Sun?

If the sun was replaced by a star with twice as much mass the gravitational force would be unbalanced and the new sun would burn the earth because if the gravitational force cannot hold than the sun would plummet towards the earth and burn it.


What would happen if replaced the sun to a blue giant?

An average blue giant is about 5-10 times the size of the Sun and are much hotter than the Sun is. If our Sun were a blue giant, life, as we know it would never have happened. The Earth would have been vastly too hot to support abiogenesis.


What kind of star will the sun be in the last stage of its life?

A Pulsar.


What would happen if you nuked the sun?

nothing would happen, the sun is constantly going through nuclear reactions


Was the sun made by a pulsar?

Our Sun is at least a 3rd generation star; the solar system formed from the debris blasted into space by countless - or at least, unknowable - numbers of supernova explosions of old dead stars. Some of those could well have left stellar cores that were pulsars. But it's unlikely that any of the Sun's mass was ever in a pulsar; the mass contained in a pulsar is so tightly bound by gravity that it is unlikely that any could ever escape. About the only way that any pulsar mass might have escaped would be if two neutron stars (and a pulsar is just a spinning neutron star) were to collide. Some of the mass might escape from the explosion, which would probably create a black hole as the result.


If the sun crashed into an invisible kinder egg what would happen?
