Bad things. If all the starts went supernova at the exact same time, we'd still only be affected by our own sun's supernova. The others starts are so far away that we wouldn't notice for years. Assuming that the sun somehow skipped the other stages of death and suddenly went supernova regardless of its mass, we'd be doomed about 8 minutes after it happens. On the scale of the universe though, there'd be complete chaos. Planets flying everywhere, no more energy for known life to exist, etc. Keep in mind that only the largest of starts can potentially go supernova, though. If only the starts big and bright enough to supernova went supernova, things would be bad but very different.
What else can I help you with?
What happens if all the stars supernova?
we all die
Why do all stars end in a supernova?
Oops! Not all stars end up as a supernova. To become a Type 2 supernova, the star has to be between 8 and 50 times larger than the Sun.
What are all stars and galaxies in?
All stars and galaxies are in the universe.
Where are stars in the universe?
Stars are scattered all across our universe but guess what? there are no stars in our solar system besides the sun!
What happens if there is no stars?
If there were no stars, the Universe would be devoid of the light, heat, and energy that stars provide. This would drastically alter the formation of galaxies, planets, and the conditions necessary for life to exist. The absence of stars would lead to a dark, cold, and lifeless Universe.
Does supernova happen to all-stars?
No. Only massive, short lived stars can supernova and only under certain conditions. The large majority or suns, including our own (yellow dwarf) will eventually burn out and become black dwarfs. However, this process takes so long the Universe is not yet old enough for us to witness the event.Nope... Stars like our sun end with a red giant then a White dwarfOnly big stars with a mass that is 10 times the sun only explode into a supernova...so basically ... nope
What are all the stars and galaxies in?
The Universe.
If you see 2 shooting stars and wish the same thing on them both is that bad?
All that happens is that the universe gets to ignore you twice.
Are pulsars found in supernova remnants.?
Yes, pulsars are often found in supernova remnants. Pulsars are rapidly rotating neutron stars that emit beams of radiation, and they are formed when a massive star undergoes a supernova explosion. The remnants of the supernova provide the environment from which the pulsar originates.
Is there stars all over in the universe?
Yes, There are.
What is a way the the universe might end?
Eventually all the stars in the universe will extinguish and go supernova, and the universe will become dark. With no light or energy the universe will become a cold and dark place, but alas, there's no reason to start selling all your stuff and preparing for Armageddon as this will take billions and billions of years to happen. Our own Sun will continue to burn strong for about another 7-8 billion years.
What element is the most abundant in the universe and all stars are made of it?
The most abundant element in the universe is hydrogen.
