Hmmmm....

Trying to think of a deep, earth-shattering question that we can all ponder upon and answer and add some progress to this worried world.

No luck so far.

Will Mr. Draper drag hisself down to station to greet Tornado when it arrives on first proper mainline run?

No, that won't change the world.

Well the King Cross to Edinburgh line runs past about a quarter mile to the West of the Towers,unfortunately some houses obstruct one's view of same from one's back window,one has determined that once one takes power one's first act will be to order them demolished and the occupants shot.

Here's one for you,What would happen to the Earth happily tootling round it's orbit if the Sun were to suddenly disappear,in a instant,poof!! gone?

tony draper,

I should imagine it would depart at a tangent!

Ohhhh, you asked what would 'happen' to it (us)... well maybe we'd fall into one of those black hole thingies!

Highness

Does she take her gravity with her? We'd still have ours, but would shoot ahead in a "straight" line in the direction we were facing when Sol split.

I beg your pardon, Mr. Draper?

What's all this about the Earth going round the Sun? I think you got your fingers in a twist there - as any fule kno and as one can clearly see (when the British clouds don't get in the way) 'tis the other way round.

Talking of "round", what happened to those blokes who headed off to "prove" the world was round? Didn't see much more of them neither, did we? Goes to show they fell off the edge.

Well probably nothing as serious should the same happen to PPRuNe...

Ah but would it take 8 minutes or so until the light reaches us before we shoot off at a tangent; or does gravity not follow the same speed limit as the electromagnetic spectrum?

Yer Mr Sun would take his gravity along wi him,the question it should bring to mind is, exactly when would we shoot off at a tangent,?

oops sorry yer posted whilst I was typing Mr M

I'd have lay-in.

Gravity

Is Instantaneous, and ubiquitous, in my universe. No eight minute delay.

I expect Mr. Higgs and his Boson to explain it from Suisse, should they lash up the Hadron.

Nope, gravity travels at the speed of light 'cos we (they?) are trying to detect gravity waves which could not exist at an instantaneous travel rate.

I believe gravity exists as a constant, which is why they can't find gravity waves at any speed when they go looking for them.

I'll be alright if the sun goes out, I've got plenty of eco-bulbs.

No, we'd shoot off in an ever-straightening curve, always getting nearer to a straight line but never quite getting there.

Here's another question. Fictional depictions of a large meteorite colliding with our planet show it crashing with some speed, usually into the Pacific, or (in recent US films) into France, althouigh this may change after tomorrow's Inaugeration.....

Suppose the meteorite was on a very similar trajectory to the planet and approaching with minimal difference in speed. Would it touch down "gently" on the equator, as in "just a nudge ?"

Yes, it would be just a nudge but just a nudge from a very large mass would cause huge amounts of damage, Try getting a little nudge from a truck and you will know what I mean.

We wouldn't know for about eight minutes. Then we could have a mourning session for the loss of Page 3 (the only two good things normally found in the comic).

That's easy, about 1 furlong per fornight faster than the speed of light, because simply you always see light after darkness.

To prove this try to open up your ice box fast enough to see the light before the darkness.

If one is suffering from flatulence and due to politeness holds it back where does it go?

It doesn't go anywhere, just adds to ruination of your lower intestine.

Get thee to the lav.
