If the Earth reversed rotation, would the magnetic poles automatically reverse as well?

Wrong: electromagnetic energy has nothing to do with the Earth's physical spin.

If you want to stop the Earth from rotating, you would need to apply counter torque (a mechanical energy only) in the opposite direction of it's spin.

Specifically you would need 6.46098 x 10^29 Joules of energy to stop the Earth at the very least.

In order to make the Earth stop and then spin at the same velocity it's currently spinning in the opposite direction, you would need at least twice the amount of energy that I cited above.

Can you come up with any sort of visualization for that amount of energy as is so mind bogglingly huge l.....does not compute lol

Mayble like a unit of time of total solar output or something?

Here you go, a link to Joules:

The zettajoule (ZJ) is equal to 10^21 joules. Annual global energy consumption is approximately 0.5 ZJ

and

The yottajoule (YJ) is equal to 10^24 joules. This is approximately the amount of energy required to heat the entire volume of water on Earth by 1 °Celsius.

Is there even a name for 10^29 joules? Thanks for the link ill read later to refresh myself on the subject :-)

The planets in our Solar system system all rotate counterclock wise except Venus and Uranus which rotate clockwise. The magnetic poles of venus are located geographically opposite to Earths. Therefore this would suggest if the spin of the earth was reversed then the magnetic poles would reverse.

How do we know that it isn't simply upsidedown ? Quite concieveable a large enough impact just flipped the planet over while keeping the same angular momentum, its only perspective from our point of view

Wrong.

Uranus rotates on it's axis just as all the other planets except Venus, it just does so on it's side since it's rotational axis is inclined to 97.77 deg.

The Earth's magnetic field has nothing to do with the Earth's physical rotation. Neither does the electromagnetic energy from the sun.

There is more electromagnetic energy in a magnet on the door of your fridge than there is in the Earth's magnetic field, so there would not be anywhere near enough energy for it to affect the Earth's spin in the first place.

It's thought that both Venus and Uranus have their axis orientated the way they do because of massive physical impacts with other celestial objects.

NOT their magnetic fields.

In universal terms i would define Down as the direction in which the gravity is pulling an object.

reply to post by AthlonSavage

Venus has no intrinsic magnetic field. The very weak field it does have is produced by its ionosphere not its core.

Please provide a source regarding the orientation of the magnetic poles of Uranus and Venus.

A planet in orbit is in freefall around the Sun. There is no "down" in orbit.

imagine crossing the galactic equator, or dark rift, and suddenly the galaxy itself is pulling in the other direction.

Kind of like how things work on earth when we cross the equator.

This force would be enough to slow the earth down, stop it, and have it reverse direction. It may just reverse the earths spin, or it may reverse the entire direction the earth orbits the sun.

Of course, its just a theory, but seeing as we go above and below the galactic equator, is it too crazy to believe that the galaxy itself has north and south poles?

Wrong, magnetism is not the cause of the Earth's spin. The Earth spins because there is no counter-torque acting to stop it.

You think eh, but the thing is, IT IS. We spin on overunity. Iron core, and magnetic poles. Earth is a free energy machine.

And anything else is the fake science. Not kidding with this either. Real mc coy.

If we suddenly got the lion, as opposed to the lamb, type of sudden pole shift, where some energy or influx, suddenly makes it finish off quickly, and we get to 0, earth stops spinning. The northern hemisphere would go into the metaphorical 3 days of darkness, and the southern hemisphere would do the 3 days of light.

The solar system is not crossing the Galactic equator but please, what happens when we cross the equator on Earth?

Dude, take a physics class, it would really help you.

reply to post by Unity_99


Yes the Earth has an Iron core. No the Earth's magnetic field does not control our spin.

The Earth's spin is a mechanical force, not a electromagnetic one.

Maybe you should take the time to learn some of the "Fake" science so you can understand better what we are talking about instead of spouting nonsense instead.

We move from the northern hemisphere, to the southern hemisphere. the coriolis effect.

Why don't hurricanes or cyclones ever cross the equator? Because they can't....

If earth was to cross the galactic equator, there would be a definite change in its spin.

Now for some reason, science says we are nowhere near the equator, then again, the ancients say we are.

It also seems to me that the dark rifts center cannot be pinpointed properly, so we very well could be crossing it.

I just refuse to believe that the mayans and other civilizations ended their calendar, to call it just another day.

You might want to rethink that:

Coriolis Effect Cause

The Coriolis effect exists only when one uses a rotating reference frame. In the rotating frame it behaves exactly like a real force (that is to say, it causes acceleration and has real effects). However, Coriolis force is a consequence of inertia, and is not attributable to an identifiable originating body, as is the case for electromagnetic or nuclear forces, for example. From an analytical viewpoint, to use Newton's second law in a rotating system, Coriolis force is mathematically necessary, but it disappears in a non-accelerating, inertial frame of reference.

You think the Coriolis effect has something to do with magnetism?
It doesn't

It also seems to me that the dark rifts center cannot be pinpointed properly, so we very well could be crossing it.

The "dark rift" is clouds of dust and gas which lie between us and the Galactic center. We are nowhere near the "dark rift". The Galactic equator is something else.

In addition, the solar system moves perpendicular to the galactic plane in a harmonic fashion, with a period of 52 to 74 million years and an amplitude of ~49 to 93 pc out of the galactic plane. (The uncertainties in the estimates of the period and amplitude of the motion are caused by the uncertainty in the amount of dark matter in the galactic disk.) The Sun and planets passed through the galactic plane about 2-3 million years ago, moving "northward."

www.astro.ncu.edu.tw...

It may not be exact but with 2-3 million years ago, it leaves a lot of room for error.

I just refuse to believe that the mayans and other civilizations ended their calendar, to call it just another day.

The Maya did not "end" their calendar. It is the end of a long count, to be followed by another long count. What other civilizations specified 12/21/12 had any significance?

But you can't just take that and apply it to the spin of planets. The spin of planets has nothing to do with any kind of galactic Coriolis effect.

If earth was to cross the galactic equator, there would be a definite change in its spin.

A planet's position relative to the galactic center has nothing to do with its spin. The Earth's spin is there because of whatever torques were applied to it during the formation of the solar system, and no significant counter torques have been applied since. By Newton's first law it will continue to spin until a force (in this case a torque) acts on it.

I just refuse to believe that the mayans and other civilizations ended their calendar, to call it just another day.

You mean like what we do with our calendar?
It's fine if you want to investigate what the ancients believed, but what you are saying about the physics of the earth's spin is just flat out wrong.

Agreed on all points


If the nature of the earth and the sun are magnetic then it would certainly be no great leap to assume that our galaxy and perhaps the universe itself is also magnetic in nature.

But the Earth is NOT magnetic in nature. What makes you say that?

Because the Earth has a magnetic field, which for all purposes is extremely weak? Again, a magnet that you use to hang up a piece of paper on your fridge is many times more powerful that the Earth's magnetic field.

Again, the Earth's magnetic field is NOT what makes the Earth rotate on it's axis. The magnetic field is a product OF that spin down in the Earth's core.

If our magnetic field were to completely shut down and disappear, the Earth would keep on spinning, because it's a mechanical type of force, NOT magnetic.

It simply amazes me at the amount of people that can't seem to understand some of the most BASIC Earth sciences that are taught in grade school, and instead, insists on making very wild (and incorrect) statements about how things work.

Yeah but school is hard. They make you like, do math and stuff.

incorrect.. sorry but KE is clearly Killswitch Engage.
anybody knows this.
