##### Why aren't Australians 'Upside-down'?
« on: 12/01/2009 08:50:06 »

Hi, can you tell me why if the Earth is round, why people in Australia are not upside down?

Sounds silly but I know about gravity and that earth is so vast but I can't understand why people that are not on top of Earth can have their feet on the ground and not be 'hanging downwards' is the only way I can put it.

If a fly say walks around a ball, when it is underneath it will be upside down, so why is this not so for people on earth. People I have asked have said it's because of gravity and I get that but it stilll doesn't explain why.

Please can you tell me, thank you.

What do you think?

If you think about it, they are upside-down - relative to someone 1800 the other side of the Earth - as are we. There is no top and bottom in space.

Gravity always pulls things and the direction it pulls them is through the center of gravity.  With a ball, or sphere, the center of gravity is right at the middle, so gravity tries to pull everything towards the middle.  This means that no matter where you are standing on a spherical object, like the Earth, gravity will always try to pull you inwards.  If you think of gravity as pulling you in, instead of down, it might make things a bit clearer.

If one person was at the North Pole and another was at the South Pole, which one would be upside down? It doesn't matter. We are basically 'trapped' on Earth and there is no reference point to determine what is up-side down and what isn't.

If you took a photo from the Moon, with the North Pole at the top, then the Ozzies would look nearly upside down.

But 'down' for them would be towards the centre of the Earth.

Aussies may not be upside-down, but they are definitely backward *hides*

None of us is "the right way up" or "upside down", what we are is "feet towards the middle".

If there was no gravity, I would fall off my chair, but so will you! So who is upside down now?
