When a planet starts to cross in front of the suns linear path around the galactic center, what stops the sun and planet from colliding like gravity would want them to do? is this why orbits are elliptical, the planet gets slingshot when looping in front of the suns path?
Do artificial satellites have to enter the earths orbit at an angle, or can they be shot straight up, and then have their thrusts turned off and they will be compelled to begin to orbit the earth? Do all satellites travel at different velocities, and if they do, is this dependent on their mass, and the initial velocity they were traveling when they left earths atmosphere?

Are you serious in saying that it is magnetism that keeps objects in orbit??????????
That's the theory, correct. But that's not the case with the moon, at least what we see doesn't exactly match the theory, so it's not correct from that perspective. This article explains more but also explains it's still somewhat of a mystery:

What I meant is that it's static now on the moon, but this tidal effect occurs to both bodies in a situation like the earth and moon correct?
This process still does not explain why the bulge is now found only on the far side of the moon. "You would expect to see a bulge on both sides, because tides have a symmetrical effect," Garrick-Bethell said. "It may be that volcanic activity or other geological processes over the past 4.4 billion years have changed the expression of the bulge on the nearside."

How does it rob the rotational energy ( that is explained above in the other posters post, the earth rotates faster so ahead of the moon there is a bulge in mass?)
Because as the earth drags on the moon to speed it up the "equal and opposite effect" is the moon's gravity draging on the earth to slow it down - it is an exchange of energy.
This wiki article has a fuller explaination - including a history of the discovery of the effect as far back as the late 1600's.

At this point, I actually find this post rather amusing, for the following reason:
Over and over again, you emphatically refuse to invest a rather minimal amount of effort and get precise answers to the questions that you have or pretend to have (and I'm leaning towards the latter). You can research satellite kinematics and dynamics to a degree almost approaching that of a professional, with all the basics and more advanced topics laid out for you on the Internet. It's the 21st century, remember? Instead, you exhibit a rather pathological tendency to dump ANY QUESTION WHATSOEVER onto ATS and then ardently demand answers to same, which would basically involve somebody re-typing the info already available or some cut-and-paste technique.
In my humble opinion, if you continue down this line, your chances of getting any sort of knowledge are infinitesimally small.

Cosmogenic synthesis... What a delightful spoonful of word soup, so deliciously spiked with nonsense for the consumptions of the fools...

You are nothing but a grumpy old man who has wasted a lot of time and space in his brain with useless information.
You have never accomplished anything of significance for the scientific community or humanity.

Ah ty for that. I will also take a look at that vid later with my nightly sandwich and hot chocolate.

the reason the orbit could be getting larger, is because if there is an acceleration (some type of sling shot) at any point in the moons orbit,
The Moon is moving to a higher orbit because of the effects of tidal locking. It is "robbing" rotational energy from the Earth and converting it to orbital energy. The Earth's rotation is slowing. The Moon's orbit is getting higher.

What a sad example of complete failure of the education system.
Your aversion to math is making your understanding difficult. If you took a few centimeters a year and multiply that by a large number of years, what kinds of distances do you come up with? I mean, this simple multiplication is elementary school math, right?

If the moon wasnt always traveling towards the earth, wouldnt it be a quintillion light millennia away from us by now?( If not constantly traveling toward the sun)
Yes, in this case, apparently you are wrong to ask if the moon wouldn't be "be a quintillion light millennia away from us by now". You're not doing too well without math.

i interpreted that to mean that the force of gravity causes massive bodies to undergo the opposite of attraction (attraction = going towards), the force of gravity causes bodies to go away from each other,

Well there you go. Your interpretation was incorrect. Gravity is an attractive force. It gets tricky though because the strength of the force is inversely proportionate to the square of the distance between the objects being considered. Perhaps this is the source of your confusion. Tidal forces are not the same as gravity. They are due to gravity gradient. The difference in the force of gravity between places on the Moon (or Earth).
But it is the attractive force of gravity which balances the angular momentum of the Moon and keeps it in orbit around the Earth.
The Moon's orbit is inclined about 5º to the ecliptic, which would make it about 65º to the plane of the Galaxy.
edit on 2/22/2013 by Phage because: (no reason given)
The inverse square law is not tricky. Its ramifications (tidal forces) can be, and often result in misconceptions about what causes tides. You seemed to be confused about how tidal forces could cause the Moon's orbit to expand.
Inverse square law is not tricky its quite intuitive, could you imagine it being any other way? like the force of gravity getting exponentially larger the further you get from the mass?
You just demonstrated that you don't understand the concept.
Is a stronger force of gravity proportional to the more mass a body has, or the larger a body is? Does a ultra dense, ultra massive, but relatively small body have a stronger gravitational force then a body that is 10 times as large but 10 times less mass?
Because the Moon's orbit is determined by the angular momentum of the Moon and the force of gravity. As the center of gravity moves, the Moon's orbit moves with it. Tie a rock to a piece of string and start spinning it around your head. Now walk forward while continuing to spin the rock. Does your head collide with the rock?
Why doesnt the earth and moon collide when the moon begins swinging around in front of earths path?
