2.5 Million stars will explode on Friday.
Supernova (NASA)
Across the Universe there will approximately 30 supernovas a second.
All day.
Right across the sky, where ever you look stars will be dying. Tearing themselves apart in world shattering explosions.
Sending out vast amounts of radiation, some forming blackholes and others vast glowing nebula. Whole planetary systems destroyed and consumed in an instant.
All day long.
And the meteorites…
Meteors (Guardian)
All around us the meteorites will be landing. If you looked carefully you would have seen 20,000 >100g meteorites hit the Earth’s surface in the last year.
Over 50 will hit us on Friday.
2 meteorites an hour hitting our planet.
Bringing material from the depths of space, with it’s different isoptopes and ancient deposits. Some of it will be from the beginning of the Solar System. Some from even before that.
Then there is the Sun.

On Friday it will crush mercilessly 600 million tons of Hydrogen every second. All day long. While we sit here under its gaze it will have turned 51840000000000 tons of hydrogen into helium through out the day and as a result will have unleashed vast amounts of radiation across the electromagnetic spectrum, much of it harmful to life on Earth. The weather will be affected, storms created, winds generated and water will evaporate.
All of this will happen on Friday 21st December 2012.
None of it will mean the end of the World.
All of this happens everyday.
Pretty amazing place the Universe isn’t it?
Now stop worrying and enjoy the rest of the week.

You’re on a roll, Paul. (ps is that all true? WOW!)
End of term- finally have some time! Yes these are averages but true.
So if there are something like 10^24 stars in the universe it would take something like 10^15 years for them all to explode at that rate. Big place, the universe.
Oh yes it would. And of course the rate of new star formation needs to be taken into account…
“It turns out that half the stars in existence now formed more than 9 billion years ago, and it took just 2 billion years to form all of them. The other half took almost five times as long to produce. If this trend continues, the universe will only get 5 percent more stars, even if we wait forever” http://www.popsci.com/science/article/2012-11/almost-all-stars-are-old-and-universe-making-hardly-any-new-ones
So I won’t change my model. 🙂
Wasn’t disagreeing with you, the problems of net speak! That said Star formation rate at present in the Milky Way is in balance with star death (approximately 3 solar masses a year each way) so the number of stars is pretty constant. In some Galaxies the rate is far higher for formation than death, while in some the rate of formation is essentially nill.
