But in Australia, we still have our feet firmly planted on the ground. When you hold up a ball and drop it, it always goes towards the ground, no matter where you are on the Earth. When the ball goes towards the sky, we say it is going “up”. When it is going towards the ground, we say “down”.
Is Australia actually upside down?
Because it’s in the southern hemisphere, which is the other side of the earth to the US. This means Australia is ‘upside down’ compared to anywhere in the northern hemisphere.
Why don’t you feel upside down in Australia?
“But I don’t FEEL upside-down when I go to Australia.” The reason is – you have a brain. And it’s very good at sensing what is Up and what is Down due to gravity. So, it “tells” you that you are standing vertical no matter where you are on the Earth.
Is the planet upside down?
Astronomers believe that at some point, a colliding celestial body tilted Venus so far off its original position that it is now upside down. The only other planet to spin in a weird direction is Uranus which spins on its side, probably the result of another collision early on in its life.
Does the earth have a top and bottom?
“As far as we astronomers can tell, there really is no ‘up’ or ‘down’ in space,” he says. So the answer to the question of which way up is the Earth is simple: it is not any particular way up and there is no good reason other than a historical superiority complex to think of north as being the top of the world.
Which is wider Australia or the moon?
Although the Moon is about as wide as Australia, it is actually much bigger when you think in terms of surface area. … The land area of Australia is some 7.69 million square kilometers. By contrast, the surface area of the Moon is 37.94 million square kilometres, close to five times the area of Australia.
What makes Australia dangerous?
What makes Australia such a hostile country? The Sun – Australia lies under a hole in the ozone layer, and ultraviolet rays burn the skin like nothing else. That’s why Australia has the highest rate of skin cancer in the world. Snakes – 21 of the 25 venomous snake species live in Australia.
Why don’t we fall into the center of the Earth?
The reason that objects don’t fall to the center of the earth is that the force of gravity is balanced by the “normal force.” Basically, this force arises because the forces between molecules in the ground are strong enough that molecular bonds aren’t broken when we step on them.
Why don’t we fly off the earth?
Normally, humans aren’t thrown off the moving Earth because gravity is holding us down. However, because we are rotating with the Earth, a ‘centrifugal force’ pushes us outwards from the centre of the planet. If this centrifugal force were bigger than the force of gravity, then we would be thrown into space.
What country is at the bottom of the earth?
|Area||14,200,000 km² 5,500,000 sq mi|
|Population||1,000 to 5,000 (seasonal)|
|Population density||<0.01 per km² <0.01 per sq mi|
What would happen if the world flipped?
The weakening of the magnetic field as it undergoes a complete flip would make the Earth more vulnerable to the effects of solar radiation, which have the power to disrupt powerlines and telecommunications.
Why is Antarctica not upside down?
Gravity is always pulling your whole body and everything around you in the direction of Earth’s core. Whether you are in Antarctica, at the equator, or anywhere else on Earth, if you’re upright with your feet on the ground, you feel (and you are) right-side up.
Why isn’t there an East and West Pole?
The poles are definite points on the Earth defined by the axis of rotation. East and west, though, are not. … Because the Earth only revolves in one direction around a north/south axis. The poles are the exit points of an imaginary stick (or “pole”) around which the planet rotates.
Does the universe have a bottom?
Our 4D universe does indeed have a top and bottom. The bottom (T=0) was the Big Bang. Space and time curved in, not to a point but to a parabola. … This is the problem of whether the universe is open or closed.
Does space have an end?
The end result is unknown; a simple estimation would have all the matter and space-time in the universe collapse into a dimensionless singularity back into how the universe started with the Big Bang, but at these scales unknown quantum effects need to be considered (see Quantum gravity).
What is outside the universe?
Outside the bounds of our universe may lie a “super” universe. Space outside space that extends infinitely into what our little bubble of a universe may expand into forever. Lying hundreds of billions of light years from us could be other island universes much like our own.
