1) How does the wind rushing over and under wings make a plane fly?

2) How does a mobile phone still work perfectly when on the move?

3) How does the sun's light travel though the vacuum of space?

1. It creates a pressure differential in the air which it attempts to equalise

2. Radio waves travel in all directions, same way as a walkie talkie or car radio

3. Light does not need air to travel on

To take up Ziggys point I used to wonder on the following 2 questions:

1. If the earth is spinning so fast and gravity is so weak then why are we not thrown off the earth into space especially people living on the equator

2. If space is a vacuum why arent we sucked out into it?

A quick google tho sorts these things out..... the answers are way more interesting than the questions BTW

However you discover that google has got to such answers to the the following ( and a good few other)


Why does a major chord sound happy and a minor chord sound sad? IN fact why do we like music at all?

How do I know I experience the same things as anyone else. How do I know that green means the same thing to me as to ziggy or orior?

What the feck is time?

I think a major chord sounds sad, which answers your second question.

Gravity isn't weak. It's a lot stronger than any negligible centrifugal force from the Earth's rotation. That only comes into play with spac launches which are more efficient at lower latitudes.


Quote2. If space is a vacuum why arent we sucked out into it?

Gravity holds us and a layer of air against the surface of Earth.

Yeah the idea was you would google these and discover for yourself unfortunately you seems to have missed the interesting bits

That is, the Earth actually spins really slow....(and btw gravity is weak)

and...

that a vaccum only "sucks" things because of the air pressure around it

Don't understand how Antrim GAA haven't developed a ground in their county to a reasonable standard, ignoring the whole Casement fiasco.

Nobody fully understands the mysteries of Antrim GAA affairs.

Not forgetting the fish lips, Botox faces and blinding white teeth.

I feel the need to put this in the 'grinds my gears' thread. You can always spot the Irish girls out here because their faces glow, they seem to plaster the make-up on with a trowel.
