So which? Survival or stunning vistas?

His name is Grylls, not Gylls I'm guessing you're not based in the UK Over here, he has something of a reputation for 'stretching it a bit' examples include use of smoke generators to make skipping across volcanic bowls look a lot more dangerous than they really are. He is also staying in...

How so? Surely to call it a number, even a special class of number, is to imply that infinity is numbered? Isn't infinity more of a concept, something that we use to help us get by in everyday technical or mathematical situations? A most elementary case in point: A circuit designer with a...

Well I don't think their visible absence necessarily precludes time travel. They probably read history in much the way we do and would no doubt understand what a paranoid, covetous generation of humanity we are (were); in short, a time-traveller from the future would likely be abducted by...

...and he's right, of course - it's simple :rolleyes:

Alpha Centauri or Pluto would be the most feasible Centre of Milky Way inadvisable owing to the black hole that I believe is lurking there and although I don't know where Earth sits in relation to the centre, it's probably a long way even at 0.5c. In the case of Andromeda (I'm no astronomer)...

Maybe I need to step back from the plight of the coffee. The OP is simply looking for a smoother ride, he's not expecting his coffee to come safely to a halt or avoid errant wildlife as a result of his smoother ride.

Possibly but if we're talking about placing a cup of coffee on a table in a car while the car is moving, it becomes pretty difficult to bifurcate the apples from the oranges. Changes in inertia are inextricably linked to rough surfaces as part of the same (typical) driving experience for the...

as I said in my last post, microbial life will inherit the Earth... You're contradicting yourself - we're successful at living in so many different environments because we're adaptable, not because we're specialised. Take the Polar Bear, very specialised for living at the Pole - not really cut...

How would you counter inertia in, say, an emergency-braking scenario?

I don't think the question was ever about destroying our way of life (although that would certainly disappear if we did) or making things less comfortable for ourselves; the question seems to be purely and simply about annihilation of either the Earth itself, life on Earth or perhaps life on...

There'd probably also be commercial reasons why it wouldn't work ie I don't know what it would cost to mass-produce a sonic screwdriver (assuming it ever became possible to build one) but would unit cost ever be cheaper than for a normal screwdriver? They'd be useful in high-voltage...

Hi you might be missing a point there - if we're reducing the Mayans to palm-reader status on the basis of a prediction then the same rule must apply to Newton, why would something so unscientific as a prediction be any more credible just because it came from a paradigm-accepted source like...

lol well there was a certain degree of levity in my original entry, perhaps I should have said an instant pole shift would result in global destruction; the last few flips - by all accounts - took around 7,000 years each. There does appear to be something afoot, the magnetic north pole...

A GPS satellite IS a clock, isn't it? A fair few communications systems rely on them for sync. So is the question If a terrestrial system was taking its clocking from a GPS satellite and you could bring the clock source to Earth would there be a relativistic deviation in sync between master...
