What will happen if the earth is stationary?

Question

the earth rotates on its axis.and after each day we become older.so what will happen if the earth is stationary.please give me a scientific answer

Answer 1

We used to think the earth WAS stationary and everything moved around it in circles.  But that didn't fit the observed facts.  The Copernican model we all learn in school, with the earth rotating on its axis and orbiting around the sun and all the planets doing the same, with all the orbits ellipses -- this fits much better, but not perfectly.  Since the Theory of Relativity, we can describe it any way we want, even go back to a stationary earth, but the math gets very ugly when you try to account for the bulge at the equator and the very complex paths of moon and planets.  The way we learned it (Copernicus) is just simpler, and more than good enough for knocking around the solar system.

But Relativity must be taken into account for the GPS system.  

Answer 2

we'd all fall off

seriously the rotation of the earth creates the gravity that keeps us on it's surface, keeps the atmosphere around the planet and gives us air to breathe.

if the rotation of the earth was less we'd drift about a bit, and if it was more we'd be a darn sight shorter.

you can't equate the ageing process with the spin of the earth because the two are not related. you would age at the same rate if you lived somewhere where the day was 10 mins long. we don't age because the of the passing of days, these are just a convenient way of marking time on this planet. time passes regardless, which is all very quantum and not something i know much about.

Answer 3

Stationary is a relative term. There are no stationary fixed points in the universe.

Even on a small scale, if you choose yourself as the fixed point them jump off of your kitchen table, the earth will move towards you until your feet stop it.

Gravity does not depend on the rotation of the planet. The passage of time

does not either. The concept of a day would change, but the only physical changes would involve climate and perhaps the planet's magnetic field.

Answer 4

Who says rotation causes gravity? Last I heard, gravity is a function of mass (the heavier an object is, the more gravitation).  Motion is a relative term.  From our viewpoint, the earth is stationary.  From the sun's viewpoint, the earth revolves around it.  From other viewpoints, the earth appears to meander like other planets when viewed from earth.  So the earth is stationary -- relative to you.  What would happen if everything suddenly stopped is a question only God could answer -- He's done it once before.  

Answer 5

Nothing in space is stationary.  There are theories that even the universe itself moves.

Answer 6

The earth's rotation is what causes the earth's gravity... and gravity is what holds in the atmosphere.  So if the earth stopped spinning, it would lose it's atmosphere.

Answer 7

Nothing will happen except as to where it becomes stationary. On one side it'll be day and on the other night, permanently. There'll be no weather seasons. These in return will have affect on the life as we know it.

I would argue through the prism of nature, that we have adapted to the conditions we live in now.

In other words if nature's balance is disturbed I would hypothesize that the changes that will result would mean, no life on earth would survive.

Earth rotation has no direct impact on Gravity.

For a more in depth answer, I think you'll be better of posting it in; Astronomy or physics section.  

While getting older in one way you are correct. It is the rotation of earth that causes day and light, seasons, 365 days etc. Which we artificially use to define our illusion of time.

Sec -> Min -> Hr -> day -> wk -> year

These are artificial segments we use to define time. So you are right these divisions give us our measure of time, which in turn we use for measure of our life, how old are you? for example. My birthday is . . . , He was 65 years old . . . etc.

. . . BUT we are aging every second, we simply just don't notice it. There are countless processes going on in our bodies, and aging process (even not fully understood yet), depends on these changes. It is just we need a certain length of time before we notice if we are old or not, in other words, criteria we use for aging or growing older is only visible after certain

amount of changes have taken place, which we calibrate using Time, which in turn is due to the result of Rotation of The Earth.
