"Spinning Earth" theorists, nutters or onto something?

No the one who thought a really good bearing is roughly the same thing.

The earth is spinning, and your brain has a mechanism for compensating for this movement so you do not feel the spinning motion - If you want to, you can disable this mechanism purely by drinking a quantity of alcohol

Sit in an aircraft or a fast train and it doesn't feel strange. You feel the acceleration and deceleration but you don't notice anything when travelling at a constant velocity.

The earth doesn't make a habit of slowing down or speeding up so there's nothing to perceive.

[jmorgan]

Yeah but what if you jump up in a train moving 125mph......

[24lemons]

Try it. Nothing will happen as you are also travelling at 125mph. If you jump and the train decelerates or accelerates suddenly then you will fly forward or back.

Ah, so it's Eddie who's turning the handle? Presumably he takes his breaks on the chesterfield sofa?

I beg to differ, if the spinning earth folk are right then someone standing on the equator goes from travelling at 1000mph in one direction to 1000mph the other direction in the space of 12 hours

Is that right?! I guess that some people are so desperate to believe in conspiracy theories that they'll buy into any old nonsense!

I think the real question is who is spinning the sky?!

It always surprises me how many are not aware the skies do this, every night of the week!

That's right, only at night though, oh hang on, night is just being on the shady side as the Earth spins about its axis.

I hope you are pretending to be stupid.

Which way does the free floating helium balloon move when the lorry carrying it brakes? Towards the front of the lorry or towards the rear?

[LHRFlightman]

Get in a lift and press the down button. At the precise moment the lift drops, jump. You'll know the floor is moving away from you but you still get a WTF moment in your head as your feet go past where the floor was.

I have no idea what this has to do with this thread, but hey ho.

Everything, it's about inertial frames of reference.

What no option for stays in the same place? (Nor goes up or down but you've not really included enough information to work that one anyway)

Assuming it's floating right at the top of the van, touching the roof, it'll move towards the back as the van decelerates.

First we have to know how the balloon is weighed and is the lorry on a plane on a conveyor belt, but what happens at altitude?

If it's touching the roof it's not free floating.

We're all spinning at 1000mph only if we're standing on the ground, if you were to jump in the air, the earth no longer has its velcro attachment on you, so you'll fire off at 1000mph into the nearest wall. That's why planes work, they just 'jump' wait on the earth spinning a bit, then land. Simple isn't it?

Correct. You can get into Oxford/Cambridge now. The air carries on moving to the front of the braking lorry, therefore the helium balloon, of lower relative density and momentum, moves towards the rear.

WHOA! Back up buddy. Who said the Lorry was full of air? And even if it is "air" what pressure is it at? There could be a vacuum in there. What if the Lorry is full of Hydrogen?

I demand better questions!
