Not for everyone. An eternity in a burning lake of fire is the destination for many according to some books I've read.
I would say climate change. Of course you would have higher temperatures and sea levels, which would reduce the availability of land due to floods. Also, the lack of frost can affect agriculture, causing famines. I feel that, as well as overpopulation as OP said, will make resources more limited to the point it becomes totally unsustainable.
Nah mate. Too many Birmingham fans punching people who play football
Betelgeuse is 640 ish light years away. You think a star that size would cause enough radiation to hit earth if it nova'd. I dont think so. It's also going to be another 1m+ years before it novas so man will be an altogether different an u recognisable species by then.
There so many ways it could come to an end, just a matter of which one gets us first really
Not according to David Aguilar the Director of Science Information and Public Outreach at the Harvard-Smithsonian Center for Astrophysics in Cambridge, MA.
Aguilar said Betelgeuse, which is part of the Orion constellation, is one star that could go supernova, bathe the planet in radiation and "literally strip life off the surface of the planet."
Who you going to believe, Director of Science Information and Public Outreach at the Harvard=Smithsonian Centre for Astrophysics or Feedy
It's a tough one, I'll sleep on it.
Alpha orionis, to give the star its proper name, is 48m x further from the earth than the sun.
If we assume the largest ever supernova emitted 600bn x as much energy per second as the sundoes, we see even at that distance, we would receive around 1/130,000,000,000 of the energy that we receive from the sun
Hmm, who do I listen to? feedy or David Aguilar, A naturalist, astronomer, author, David's expertise is in communicating the wonder of science. He is the past Director of Science Information and Public Outreach at the Harvard-Smithsonian Center for Astrophysics in Cambridge, MA. In 2015, he left Harvard to join NASAs New Horizons special media team on the Pluto flyby mission. He is a Random House/Smithsonian and National Geographic author and illustrator of 7 books on astronomy including "Cosmic Catastrophes - 7 Ways to Destroy a Planet Like Earth"; "ALIEN WORLDS"- a look at how bizarre alien life may be throughout the Universe; "13 Planets", and "Space Encyclopedia". He is past Director of Fiske Planetarium and Science Center, and the founder of the Science Discovery Program at University of Colorado Boulder; past Marketing Communications Director at Ball Aerospace and Technologies Corporation and member of the Hubble Space Telescope repair team; past Marketing Director of "Evolution", PBS's Emmy-winning 7-part NOVA series. Hmm it's a tough one.
I guarantee that a-orionis is too far away at 600+ light years to affect earth at any significant level.
Contemporary thinking says any supernova would need to be between 100-150 light years to cause any effect on the earth.
Well I for one will be sleeping easier now it's guaranteed as not an issue
David Aguilar you say
Betelgeuse and 2012 - Bad Astronomy
Cosmic Catastrophes: Seven Ways to Destroy a Planet Like Earth. It's in his book.
Some blogger versus a NASA bloke from Havard.
Believe what you want. A supernova more than 100 light years away isnt going to affect the earth. The distance is just too far for its luminosity to be comparable with the sun.
NB hes no blogger, you need to do some research
