er, nooooo...I'm saying that the ones in space have to be adjusted for time dilation, for really realz.
Are you saying then that time dilation is a fancy way of saying the effects of gravity and velocity cause the clocks at height to run slower than those closer to the source of gravity?
it's not "height", and they're not technically running slower, but...yes.
Stay with me, I'll go through it slowly (and hope I get it right):
gravity is acceleration (you'll have to take my word for this, but you're being accelerated towards the earth at a pull of 1G right now, for instance). Gravity is a sort of velocity change (therefore, relative motion).
Both relative motion and therefore acceleration (which is a change in relative motion) will throw off two clocks in differing frames of reference.
The clocks in space are not moving relative to the surface of the Earth, but AND they ARE in a weaker gravitational field and they ARE moving really quick.
The clocks in the planes could fly as low as they chose (practical limits aside) BUT they were also moving relative to the "stationary" clock on the ground.
Both situations offer differing frames of reference when comparing two clocks with each other.
Since our need with GPS is to be accurate in a frame of reference placed squarely on the ground, and our clocks are in a different frame of reference, we need to take time dilation into account - if we didn't, relativity would be wrong. We do, so something's up - and the equations given to us by Einstein work remarkably well for being a shot in the dark, no?
Space doesn't exist because Space isn't made of particles or waves. After all, space is the emptiness between particles, but ICANT says that anything that exists must be made of particles or waves.
can I get an AMEN!
Therefore, there is no emptiness between particles.
Truly, space does not exist - we all live in an infinitely dense point of no dimensions whatsoever (can anyone actually tell me what a Height is made of? No?) - maybe though...this one spot is just really, really big?
ICANT says the Bible is true. In the bible, snakes can talk. All those times I have heard snakes hissing, I never knew that they were actually speaking a language. How deaf I was
I weep brother, I weep openly for the truth has set you free. Besides, I thought everyone knew they spoke parceltongue?
And since Science is not trustworthy, I cannot bring myself to fly in a plane built by science. Next time I need to fly, I will fly in a plane built on faith that God will lift the plane into the air, move it across the globe, and set it down where I need to be.
It is by faith alone that they fly! nothing heavier than air can fly without the grace of god. Not that gravity (heretical, evil nonsense) exists of course.
Birds, it is so obvious, live in a perpetual state of grace where sin doesn't weigh them down.
1) it's not MY essay, it was merely one of the first I found discussing the subject
2) The action of the moon on GPS satellites is quite probably small enough that it doesn't affect the calculations - at some point you have to give up and say "margin of error". It's what you call "diminishing returns" - the payoff from taking it into account is either so small, or the difference so negligible, that it simply isn't worth it. The moon? How about the SUN? How about the four gas giants in our solar system? How about globular cluster M1? Why stop there? Perhaps you'd like the author to take into account all of the matter of the known universe?
When you've reached your quota of 10 posts, can we assume you'll leave, or stick around and attempt to learn something?
At any point in time there would always be a percentage of satellites on the other side of the earth completely devoid of lunar grabitational influence.
Just because I think you're somebody who is self-impressed with their own smarts but could one day make a difference to the world, I intend to give you a gentle nudge towards REAL math and science rather than homeschooled fail or religulous technobabble.
I'm sorry to break it to you, kid, but mass does NOT shield from the effects of gravity.
If you want proof, then you'd have to get a really big rock to stand on. If you don't float away, the mass of the Earth is still pulling on you.
You can measure this if you want - try to weigh yourself close to the earth's surface, then get on your mobile really big rock and weigh yourself again - you'll be the same weight.
The only reason this would change (as discussed) is if you are far enough OUT of the gravity well of the planet Earth that it's cumulative effect on you is diminished.
Gravity reduces according to the inverse square law - hence we probably don't need to take into account the moon and the sun.
And yes, I'm lazy, I'll leave that as an exercise for YOU since you're not happy with the theory and I am.
