How long?

In FE theory how long has the Earth been accelerating at 9.8m/s²?

Oooh, that's a good question. We would assume since the creation of the earth, but then again, some of these people are likely young-earth creationists, who think the world is like 10 000 years old.

In FE theory how long has the Earth been accelerating at 9.8m/s²?

The earth is what...4.5 billion years old or so?

Hey Mikedar

According to "Young Earth Creationists"  Bishop Usher worked out the  Earth was created on October 26 4004 BC at 9 o'clock. In the mid 1600,s.

>>>The earth is what...4.5 billion years old or so?<<<

So FE theory agrees with mainstream thought as to the age of the Earth?

You can quote you know.  And why wouldn't they? 

Oh, and to be more precise its been accelerating all that time?

Good question.  What of the creation of the UA?  It must have been around since creation, or the earth wouldn't pull together would it?

I assume so, or else some catastrophic event must have occurred that caused the earth to lose her gravitational field and began the acceleration.





BTW, I know where you are going with this, and there is no need to bother with the calculations. 

>>>BTW, I know where you are going with this, and there is no need to bother with the calculations. <<<

Are you sure?

I was more interested in how a body traveling at a substantial proportion of c stabilizes its self with out the use of a severe  rate of spin to gyroscopically stabilize it?

I'm presuming its   accelerating  with respect to instantaneously comoving inertial frames.

It's travelling through open space.  Would that make a difference?

Because the UA is only acting on the "opposite" side of the the Earth that we are on

I'm confused, explain.

A cylinder can rotate on either its x or y axis

If the Earth rotated on its x axis we would fall off as it appears the UA only acts on the Earth not us (if the Earth rotated 180° it would accelerate away from us)

To have a gyroscopically stabilizing y rotation would cause structural instability of the Earth.

Doesn't the UA act on us?  And why would it accelerate away from us if it rotated

Doesn't the UA act on us?  And why would it accelerate away from us if it rotated

If we are both being accelerating at the same rate from the same "u" and jumped up the Earth wouldn't catch up  with us

Tom said the UA acts according to mass.  The earth has more mass, :. it is accelerated more.

Yeah, we've already had a discussion about that. It doesn't make sense as more massive objects would feel lighter.

Well I missed that, but I guess I'm wondering what the new theory is now though.

Opps!

But we are getting side tracked
I'm more interested in what systems allow an object accelerating at 9.8m/s² and traveling at a significant proportion of c maintain its stability and orientation for billions of years.

The reason it can keep accelerating is because there's no fixed frame of reference by which to meaninfully state its speed or velocity. Without this, it will never reach any given speed or velocity, it will just accelerate. This may sound a little wacky, but it's a fairly simple idea to grasp.

The only way we can gauge speed, and the only way in which it is at all meaningful, is if there is a fixed reference point away from which the speeding object is moving. With the Earth, this is not the case.

well there's the far away stars we constantly gaze at. in fact...it is by analyzing the red-shift of the stars in the farthest reaches of the universe that we have come up with our predictions of how old the universe is and when the big bang was, and the rate of acceleration at which the universe has been expanding (which, incidentally, is not constant, so not really compatible with UA...)

so unless UA is pushing slightly harder at times and slightly less hard at other times on the far away stars than us...

Well actually, if you read a few of my old posts about the UA and other planets/"stars", you'll find that I don't believe in an even UA either, certain parts of it are crests and troughs (though they all push in the same way).

Im not asking how or why it is accelerating Dogplatter rather how Earth maintains its stability and orientation for billions of years whist traveling at pretty much c.

I may add if you cant meaningfully state its  velocity it means you cant ascertain displacement ....then you cant ascertain acceleration.But lets not get side tracked......

Can you prove that the Earth has gravity?

>>>Can you prove that the Earth has gravity?<<<

Not trying to.
Simply asking for a concise and thought out answer from people who subscribe to FE theory in relation to ..."how Earth maintains its stability and orientation for billions of years whist traveling at pretty much c."

Not poking fun, not treating them as a side show , not using rude words or derogatory phrases or attitude.Just an answer.

Oh my god! Someone who understands relativity! It's a MIRACLE! I love you...


I mean, what?


Oh, how it retains stability? I don't see why it wouldn't. Firstly, keep in mind how HUGE this "disc" is. It's gargantuan. Secondly, obviously since the rest of the universe is being accelerated by the same force (presumably), the UA must pass the Earth along its sides as well, and thus isn't necessarily being pushed from the bottom like a wave, but rather being carried along as if with a current. Thus, the stability is pretty much assured unless turbulence was hit, but since we're in free space, I don't know what kind of torrents we would run into that could knock such a massive disc out of orientation.

The answer can be as simple as many of the RE answers: "If it were any other way, we would never know it."

You cant deride it if you use it.
