I think people are giving gravity way too much credit... So we'll be lined up with the galaxy? It's really a very weak force... And we're in orbit anyway, so we're already feeling most of the gravitational effects the galaxy has to offer...

isn't gravity the strongest force in the universe, black hole's at the centre of galaxy? Dont think that's weak?

Of the four fundamental forces it is the weakest.

Gravity is by far the weakest (for example the next strongest force - the weak nuclear force - is 1000000000000000000000000 times stronger). Its weakness relative to the other forces is actually one of the biggest mysteries of modern day science.

And when the LHC kicks off we will hopefully find out the force of well...everything..can't wait

gpjordanf1 · 03-07-2009 04:17PM

thanks very interesting i alway's took gravity as the strongest with black holes being the end result.

Compare attraction of a couple of lead balls for each other compared with a pair of rare earth magents used in earphones.

or paper for a comb (electrostatic)

Try and pull the atoms apart in a stainless steel rule or a tape measure...

The lead balls have to be huge before they have enough gravity to want to stick to each other...

Magnets strong enough you can't pull apart by hand will fit in your pocket.

03-07-2009 06:20PM

Here's another interesting way of thinking about it. If you've a piece of iron sitting on the ground, the entire Earth is gravitationally pulling on it; yet, you can pick it up with a magnet that's many many millions of times smaller than the Earth.

I think all this is more to do with frequency than anything else your talking about.The earths is going to increase over the next few years, beginning in 2012.

What do you mean its frequency? What kind of a frequency does the Earth have that can increase?

polishpaddy · 03-07-2009 09:30PM

Everything has a frequency.For example, when you look at a plant you see the colour green,the frequency being 540 (1012 Hz) terahertz.

No everything doesn't have a frequency.

Only things that have a cyclical process have a fequency.

But that's light. Light is an electro magnetic wave.

The Earth isn't a wave.
The only frequency it has is it's orbital period. And that it's changing any time soon.

That's different, though. A leaf "gives out" light which has a frequency of about 5.87x10^14 hz, that doesn't mean that the plant as a whole vibrates at that frequency: it means that certain (the majority) of the atoms in the leaves vibrate at or around that frequency.

The simple fact is that the frequency of a body composed of many many atoms is essentially cancelled out by the vibrations of the different atoms. If every atom vibrated in harmony, then there may be a substantial effect; but they all vibrate out of harmony at different frequencies; leading to an overall cancellation as a whole.

A body such as a phone doesn't have a frequency as you describe, as it's composed of too many different kinds of atoms. A body such as the Earth certainly doesn't have a frequency as you describe.

I didn't realise you knew so much about this topic.I tried to answer your question in a simplfied way.

The frequency i was referring to was not the magnetic field, as this has a frequency of 0hz.

A body such as the Earth certainly doesn't have a frequency as you describe.

I was talking about the frequency from the ionosphere down to the ground.So infact the earth has a frequency.

King mob; Does light have a frequency?
JammyDodger; Would you say a human has a certain frequency?

2012 = London Olympics.

polishpaddy · 03-07-2009 10:49PM

Best answer so far i think

But the Ionosphere reflects radiowaves.
How does this mean the Earth has a frequency?
Is it radio waves emitted?

Yes, because it is a electromagnetic wave.
The frequency and wavelength of which determines the colour you see.

polishpaddy wrote: »

No humans don't have a frequency as they do not vibrate, orbit or are waves.

I'm getting the impression you don't understand the subject matter.?

I get the impression we're moving away from the topic. Make it relevant ppl.

Really?
What gives you that impression?

You're the one claiming the Earth has a frequency.
What is that frequency exactly in hertz?
Is it a radio wave? Orbital period? Light wave?

How do you know it's changing?

The plant is not generating green or vibrating at green frequency. The other colours are absorbed and the green reflected by the molecules.

polishpaddy · 03-07-2009 11:34PM

The plant is not generating green or vibrating at green frequency. The other colours are absorbed and the green reflected by the molecules.

I was trying to explain to him how something has a CERTAIN frequency, in this case light, ie the colour green.

Really?

Your learning as you go along i can see it in your posts.

What is that frequency exactly in hertz?

Is frequency measured in something else besides hertz?

Is it a radio wave? Orbital period? Light wave?

If something has a frequency it has a wave lenght, right?

How do you know it's changing?

I've read about it.

Sorry, I didn't mean to try and trick you out or anything; I was just genuinely curious as to what you meant by everything having a frequency.

I wasn't referring to a magnetic field, either.

Earth doesn't have a frequency. I'm not even sure why you're saying the ionosphere has a frequency.

Do you mean the frequency of vibration of electrons in the ionosphere?

Do you mean the frequency of collisions in the ionosphere between electrons and other particles?

Or are you talking about ionospheric radiowave propagation? (i.e. what frequencies of radiowaves the different layers of the ionosphere allow to propagate?)

You're being extremely vague.

JammyDodger; Would you say a human has a certain frequency?

No, I wouldn't. You haven't defined what you mean by everything having a frequency, so what you're saying is extremely vague.

The only thing I can think that you're talking about is the fundamental frequency of an object (i.e. the frequency an object tends to vibrate at). But that concept doesn't apply to conplex structures such as the human body, or even the Earth (as it's a physical vibration).

But you see the difference between light and a planet right?

Unfortunately that's not true at all.

polishpaddy wrote: »

Nope not really.
Hertz is defined at number of cycles per second.

Can you describe the frequency of the Earth in hertz or not?

polishpaddy wrote: »

Nope, only waves.
Orbit have a frequency but not a wavelength.

What is the medium for the frequency of the Earth?

Frequency is an abstraction, a wave property.

It is descriptive of that particular property of a wave. It need not necessarily apply to a wave either, which is why you need to be specific on the type you are talking about.

galwayrush · 03-07-2009 11:47PM

I know what 2112 is all about, guess 2012 is a hundred years before hand.:rolleyes:

I was under the impression that we all vibrated at a certain frequency?

Yes i understand that.Highter the freuqncy the SHORTER the wave lenght etc i know thats why mobile phones have small aerials.

There are other calanders too that mysteriousely end around that time.

I can't wait....Yipee

Great! Less calenders = half the confusion.

2012, what's it all about?
