Sorry about the previous, incomplete reply. I hit "post", rather than "preview" while trying to figure out how to spell "Chandrasekar". I kept thinking Chandra Levi, and I knew that wasn't right.

Mr Samuels somehow either ignores or overlooks that it would be 150 years before we even know there has been a supernova and/or we feel the effects, if any.

It is so close that if it were to blow up before moving away from us, it could wipe out life on Earth. Let's hope so. Mankind has outlived its usefulness.
Yes indeed. We all know that the planet is being destroyed by mankind, particularly white North Americans.
This should please the fine members of Earth! First!

I have heard reports that Earth is already on the road to becoming uninhabitable by humans due to the CO2-O2 cycle breaking down.
The short version is that plate tectonics combines with weather to keep temperatures between boiling and freezing points of water over the very long term. In Earth's early history, when the sun was much more feeble, there was much more CO2 in the atmosphere.
According to the article I read, or heard, the sun was already hot enough that critical amounts of CO2 will have to be removed from the atmosphere just to keep temps from soaring and oceans from boiling away. Soon, the Earth will remove so much CO2 that plant life will be reduced. Long before the sun goes to Red Giant stage, advandced life on Earth will be blotted out. The article said this was already beginning to happen, and that we don't have 4.5 billion years, but much closer to 4.5 THOUSAND years, before this becomes a noticiable and increasingly serious problem.

"This is also hundreds of millions to billions of years in the future." Oh, I see! Billions, not millions.
Whew! You had me worried for a moment there.

"But do not panic yet. "Very soon" could mean hundreds of millions of years in the future"The "Nike" wearing Y2K nutjobs that didn't jump aboard Hale-Bobbit might find use for their freeze dried foods yet!!!! Just have them make sure the shelf life is a couple of million years. :-)

I just hope it goes off at night, I want to see the light show!
Eastern time, mind you...

Thanks for setting the record straight, in other words this is cheese.
Or A KORANS DR MINTS, which is what Karin Sandstrom's name comes out to playing with the anagram server. ;)

And that is just as well, because we are only 150 light years away from HR 8210 at presentIf its 150 light years away it could have gone Supernova during the Civil War and we wouldnt know it yet
(and some freepers will blame that on Lincoln too;)

Soon, the Earth will remove so much CO2 that plant life will be reduced. What, no more salad bars? What will the veg heads do then?

"high-speed gases, moving at significant fractions of the speed of light. Just the thing to rip the atmosphere off of a seared planet."
Aw heck,that happens around here ever time Ah makes chili>

If it did let fly, the high-energy electromagnetic radiation and cosmic rays it released would destroy Earth's ozone layer within minutes, giving life little chance of survival. Isn't it a coincidence that Harvard published this article on the very same day that we find out:
Ozone Hole to Mend itself by 2040 according to Japanese Scientists...hmmmm? (^:

I tend to think that the letter from Karin deploring the bonehead reporter is genuine. I especially liked her last note of ignoring reporters. That's how I know she is still a student.
Once she is a full professor she'll understand that reporters are very useful in keeping the grant money flowing. A typical feminist sociologist would correctly understand that this problem will keep her in grant money for 300 million years.
