What If a Supernova Exploded Close to Earth?

Twinkle, twinkle, little star. How I wonder what you, wait a minute, why are you twinkling so much? Um, guys, that's no diamond in the sky. That looks like a supernova. As much as we love to blow stuff up here on Earth, no bombs or pyrotechnics could compare to the incredible force of nature's biggest explosion, the supernova. As a star reaches its grand finale and explodes, what would happen to life on Earth if we were close by? How far away from a supernova are we considered safe? Could anything survive its deadly radiation? What makes supernovae valuable to us?

From the 2002 movie Frozen, The super brightest star Sirius from the Eridanus Constellation exploded into a hypernova close to Earth and froze all life on Earth, The Sun, Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune, the dwarf planets, the stars and even the galaxies have froze too. And then 5 Billion Years Later, The Sun heats up and melts all snow and ice and unfreezes all life on Earth. The Great Thaw occurs when the Sun heats up with all stars causing it to melt all the snow and ice around the universe, eventually unfreezing all life on Earth.

Its so cool to hear em talk about our univers and all that knowledge. but then its like -its just so happened that were on a petfect spot in galaxy plus a living planet that we dont need to worry- xD thats cuz theres a creator. we build telescope to see so far away. but we remain blind to the miracels just in front of us
reply

That would be Venus. Planets are not fully lit up unless they are perfectly on opposite side of earth from the sun on their orbit. The irregular shape you see that looks like explosion is just a planet phase mixed with blue focus. With a quality telescope, Venus sometimes looks like a crescent moon due to waxing or waning.

At least a supernova shockwave is limited by the speed of light, and the kinds of stars that could go supernova have light-years of distance away from us. Also if the supernova happened, by the time it reached us, would have already happened at least 50 years by the time it reached us.
reply

There-s might actually be a super nova explosion in 2023 because there a two stars coming very close together and there coming together as we speak. To make it worse it-s close to earth. If I-m wrong don-t blame me blame the short that I got this information from.

Short story short there would be no sound, physics wouldn't allow that and secondly a lot of things would hurl towards us and anything large enough would destroy the atmosphere and we would run out of oxygen a lot of meteorites would hit also.
reply

Wonder if we would have advanced warning and detect it coming or if it would travel light speed and kill us before an emergency broadcast alert hit our cell phones. Then again not much point in issuing an emergency broadcast. -

The Ordovician Extinction, one of the six mass extinctions, is believed to have been caused by a supernova within 10 light years. In any case, the odds are very much against a close supernova
reply

In the last science update, there's no sun in our neighbourhood. It seems that our solar system is in one big void. So the next sun is around 500 lightyears away -

One. Explosion. In. Earth. And. It's. Destroy. In. A. Minute. Because. Of. High. Speed. Explosion. Also. Possible. In. One. Special. Area. Which. Poisenus.

I thought this was called - What If - not - maybe put us in risk-!
edit: at least its been more than 2, 023+ years and it probally has not happaned

reply

Well if it exploded the explosion has to stop exploding at some point right? How long after we get hit do we have to be underground?
reply

I met you in california
you said you loved him in gorgeia
your heart is in ground frozen over
my hearts in the sky supernova

reply

What happened when supernova is coming near to our earth in this century. just imagine. i wish to born in another universe at that time
reply

If those materials comes to earth there could be no life left. Just imagine our sun exploded what do you think will happen to us.
reply

There are some things that should concern us, but this is not one of them. There are no supernova candidates close to earth.
reply

Does anyone know the movie the clip in the beginning is from? I assume it-s a movie since it says -movie clips. - -
reply

Don't worry we will only get like 1500 damage and some effects like some might turn confuse, morph into frogs, etc.
reply

-Casting shadows, even during the day. - Uhhh. yeah. That's what's supposed to happen during the day.

Why don't you make another Hollywood moon landing in color images? Or send Bruce Willis to save earth
