Just remember that you're standing on a planet that's evolving
And reolving at nine thousand miles an hour.
It's orbiting at nineteen miles a second, so it's reckoned,
The sun that is the source of all our power.
Now the sun, and you and me, and all the stars that we can see,
Are moving at a million miles a day,
In the outer spiral arm, at fourteen thousand miles an hour,
Of a galaxy we call the Milky Way.
Our galaxy itself contains a hundred million stars;
It's a hundred thousand light-years side to side;
It bulges in the middle sixteen thousand light-years thick,
But out by us it's just three thousand light-years wide.
We're thirty thousand light-years from Galactic Central Point,
We go 'round every two hundred million years;
And our galaxy itself is one of millions of billions
In this amazing and expanding universe.
Our universe itself keeps on expanding and expanding,
In all of the directions it can whiz;
As fast as it can go, that's the speed of light, you know,
Twelve million miles a minute and that's the fastest speed there is.
So remember, when you're feeling very small and insecure,
How amazingly unlikely is your birth;
And pray that there's intelligent life somewhere out in space,
'Cause there's bugger all down here on Earth!

I will need more time to think about all of this but I want
to give it a try...They will call me stupid...I don't care.
When you mentioned and I already knew about that but this is my point...Our universe itself keeps on expanding and expanding,
In all of the directions it can
Could it be possible that the earth is attracted toward the sun?
I don't know if it would be due to the expansion or gravity or some kind of magnetism.

yes the earth is attracted to the sun - which is why it doesn't spin off into deep space.
The gravitational attraction is what stops the earth going in a straight line, and forces it to curve around the sun.
If you're interested in this sort of thing, try to pick up a good documentary called "Origins"
(it's a pbs nova special)
they might have french subtitles

The earth circles the sun because the sun is warping the fabric of spacetime. I've said this a million times - to visualize what is going on in simple terms, think of putting a bowling ball on a bed. The bed will warp around the bowling ball. Put smaller marbles near the bowling ball, they roll toward it. But the earth doesn't fall right toward it, we orbit it....but the idea remains the same. Dense objects, all objects for that matter, warp spacetime around them....pete wrote: Man Thanks

or something like that.
magnetism?

it might help if you understand the history of the solar system and the earth.
look up the nebula hypothesis on google. If you're lucky you might find a good animation.
Else get your hands on this documentary:

Put a ball at the end of a stick attached to a rubber band.
If you spin the ball faster the ball will move away from the stick.
The slower you spin the ball the closer it will get to the stick.
This is the same principal in the Universe. Our moon is traveling faster than the gravitational pull of the earth so it is moving away from us.
Depending on how fast the earth is traveling around the sun will determine weather we are moving closer or moving away.

I know...We are already in it, I meant closer to the sun.
And thanks a lot for your participation.
I really appreciate it.
Men, I didn't know there were so many, so well educate people
in a forum like this, were people are here to play games in the first place. To all of you, thumbs up!
Take Care

I don't know about anyone else, but it will sure help me out alot.tnf wrote:pete what i don't get is how we are going to reconcile the rift between quantum mechanics and relativity. do you have an innovation that can do that?
i can give you some basic dimensions of subatomic particles if it will help.

I went through a few articles about quantum mechanics, I never learned it at school and never took the time to go into it since you just mentioned it.
It’s quite impressing to see how it resemble the theory of relativity and how it compared in ways to the way Universe work.
I will have to go into more studies before starting to give my opinion on it…I guess you can understand.
I love those type of studies. Wish I would be a teen at school right now with al the knowledge and tools EG pcs & internet for our research. I was the one with the biggest list of books at my school library at the time, we didn’t have access to internet then.
I already have a thing on it though but it is premature to tell.
Thanks for all of your help.
PS; Would you know of a site that is really professional for it?
I went through a few quite instructive ones but just in case I missed the one.

Thanks for the links
I read the first one now I will go through the others.
Talk about it later.

No pete, string theory, superstring theory, M theory, whatever, is an attempt to reconcile the fact that quantum and relativity both cannot be right. There must be one theory, one set of laws, that will explain the behavior of the universe on the large and subatomic scales. relativity will explain the behavior of the cosmos great, and quantum will explain the behavior of subatomic particles great, but you can't use relativity to explain the behavior of an electron and you can't use quantum to explain the motions of the planets.pete wrote:Thanks Sir TNFtnf wrote:Pete go read about string theory.
At first I thought You were joking.
I never heard that one, I don't know what it is in french, I will find out.

What I don't "comprehend" is:you can't use relativity to explain the behavior of an electron you can't use quantum to explain the motions of the planets.
The green part is the one wich is still not feasilble yet , not understood...
But the red part..I missed something or it really can't be done?
Pete
The theory of relativity cannot be used to explain the behavior of an electron. Applying the equations that deal with relativity to the subatomic world result in nonsense answers. The theory of quantum mechanics and the equations that it employs cannot be applied to the motions of the planets, the stars, galaxies, etc. Using equations from quantum mechanics on these objects results in nonsense answers as well.
