Default Ever wondered what you would do if a comet was about to strike the earth?

Here are the top 20 underground bunkers in the UK that could save your life...

Sky 1 is preparing to release its new 10-part British comedy-drama 'You, Me and the Apocalypse' starring actor Rob Lowe
As a huge comet hurtles towards Earth, the show's characters find themselves underground watching it all unfold on TV
Keeping with the apocalyptic theme, MailOnline has listed the best places to hide in the event of a catastrophe

Entrance: This steel, airtight blast door leads into the bunker. Sealed
from the inside, it is eight inches thick and weighs 30 tonnes. There
are armed guards on the other side

We used to have this discussion as teenage boys. There was a certain teenage girl's house that was likely to get a lot of visitors.

A comet ? Nothing ... A rock of the same size ? Farewell to loved ones

A ball of water ice, frozen gasses, dust, and boulders or an asteroid of solid rock. At the entry speed either would be moving at it really wouldn't matter what it was made of. The results would largely be the same.

Generally speaking comets move at a higher velocity than asteroids due to the fact they originate much further out so have farther to fall down the gravity well.

Density difference of 5:1 and low boiling point ---> much lighter impact or no impact at the ground level

Velocity of 15 miles per second (low end for a comet) so transit time from edge of atmosphere to impact with planet surface = negligible.

Small comets and asteroids their density would play a greater role. At eight miles in diameter it will be cold comfort that it only made a 100km crater instead of 200km.

You should read a novel titled "Lucifers Hammer." The authors devoted several pages to explaining why it really doesn't matter much what it's composed of once the size and velocity passes a certain point.

One of my favorite apocalyptic novels. Don't we have a thread about those?

NV, the show 'You, Me and the Apocalypse' is supposed to be shown on NBC. I think it's supposed to be later this fall, possibly November, but I'm not sure.

Could be a fun show.

I tried \minority Report last week - yawn. Blindspot - not sure about that one yet... I'll give it another episode or two. Fear The Walking Dead - several episodes of introduction that could have been dealt with in a cleaner, more speedy fashion.

Going to try Code Black Wednesday night but so far, I've not been overly impressed with new network offerings.

OH caught the trailer for "You, Me, & the Apocalypse" the other night and commented "Ah, you'll be watching that then..." He's getting the hang of things.

Of the bunkers listed, aside from the London ones, I've been to Hack Green in Cheshire several times. Some of the government issue gear that furnishes the various rooms is what I used when I started work (civil service in the 1980s), so a real set of memories there. I remember the giddy heights of Grade 7, when you got a rug, a coat stand, and a green padded desk chair with arms, still available at the bunker and just as uncomfortable now. And one of the main scenarios set out at Hack Green covers the city where I now live.
