i heard that the earth is not moving what do you think ????????

Question

i have heard from a friend of mine that the earth is not moving and it is stationary and all the sun and the moon are turning around it and that NASA is telling lise
and then i thought about the satalites on space what makes them move do they use fule to move them and and how many times they send fule to it
and more and more in my mind is going on
i think my friend it right what do you think ?????????????

Answer 1

Your friend is an idiot... if the Earth did not rotate, we would not be able to generate enough gravity to remain here... we would in essence be a dead planet or simply a traveling rock !

Answer 2

Many of the responders here note that the earth's rotation is mostly or partly responsible for gravity.

That is simply not the case. Gravity is a property of mass. ALL mass exerts gravitational force, whether it is moving or rotating or not.

Now, on a spinning mass such as the earth, an object will WEIGH slightly less at the equator than at a pole, due to centripetal acceleration. But a 1kg mass at the equator would have the same mass if moved to the pole (discounting very slight relativistic effects of its motion through space).

The sun outmasses the earth nearly a million times. It is obvious that all eight planets orbit the sun. The change of the constellations through the seasons also suggest that. The very seasons themselves are explained by earth's axial tilt, as it revolves around the sun.

Astronomers used to use complicated epicycles to explain the motions of the sun and planets around the earth, but the sun centered solar system is far simpler, superior, and more rationally explains all the evidence.

Answer 3

The motion of the earth is provable in several ways. First, is stellar parallax. When measuring parallax there is an effect of the revolution of the earth (I think it's called aberration, but don't hold me to it) that causes the light of the stars to seem to make little, tiny ellipses (it's caused by our moving through the stream of light from them and seeing the light at different angles) that must be removed from the measurements. The second way is intuitive..if the stars were revolving about us then they are all at the same distance (and wouldn't show parallax at all) or their velocity would increase with distance, in a regular way. We can measure proper motion (motion across line of sight) and it does not increase in a regular way with distance, nor do all stars that show proper motion move in the same direction. So, it is proven by these physical tests that the earth does orbit about the sun, not the other way around. I have left out the obvious, such as planetary retrograde motion, phases of all the planets (even the superior planets have phases, only full or gibbous), and the like.

Your friend, then is incorrect, and has not studied astronomic history well enough to realize the fallacies of his or her contentions.

In a way, however, your friend is right, because as a frame of reference to all earthly activities, even earth orbital activities, we can think of the earth as being stationary.

Answer 4

Movement is always relative to a reference.
Most people use themselves as a reference when deciding that something is moving.
After a little thought some people can see (and trust) that when another person (who might be moving differently) decides that something is moving that it is indeed moving.
The difference between what a person sees and what another person honestly reports as motion gives rise to the idea that all motion must be considered relative to the observer.
The Earth was used as the standard reference for motion for so long that the idea that the Earth was also moving confused a lot of people.
An absolute reference of "space" was then assumed to decide motion.
Since space (without any matter) cannot be referred to (one cannot decide if the nothing is moving with respect to the nothing) a three dimensional "fabric" of space was thought to exist. It was called the Ether.
In 1887 the Michelson-Morley experiment was conducted to find out how fast we all were moving (and in which direction)with respect to this "Ether".
It turns out that there is no "Ether" but it took Einstein to properly explain that everything is relative to everything else.
So the Earth is both moving and not moving depending on how the observer is moving.

Answer 5

Scientists think it is moving. Around the sun.
Satelites are 'falling' all the time around the earth. Imagine the earth as a globe, or a ball, and the sattelite falls next to it, before it drops away from the earth, the earth's gravity pulls it back into it's orbit around the earth.

Answer 6

no offence but your friend is completely wrong. the earth moves around the sun as do the other planets in our solar system, along with spining on its own axis. to add even more the sun and all the planets in themselves are moving around the edge of the milky way. and to expand again the milky way is most likely travelling in a vector out in space. so in reality the earth is actually moving in four "directions" or ways all at once. in response to RUSTY POTATO gravity is partly due to centrifugal forces but it is also to do with mass.

Answer 7

how old is your friend? 5? if the earht was'nt moving we would all fall off! you can tell the earth is moving by looking at the clouds. just trust a little thing called frame of reference.

PS. rely on your science teacher more than your 5-year-old friend.

Answer 8

I think that the Earth is moving. It's just common sense.

Answer 9

The last time that I heard this was from a Catholic school science teacher in grade school.

Answer 10

Your friend is right and the rest of the silly scientific community is lying. It's just one big global conspiracy created by aliens in their quest to rule the earth and make lab rats of us all.
WE'RE DOOMED!!

Oh yeah, plus, the world is flat.
So don't travel too far. : )
