Now, what is it that transforms “sensory input” into “knowledge”?

I claim that the space-time fabric which Einstein describes is not accurate. Space is not flat at any time! Therefore, we cannot use a one-dimensional vision to recreate a multi-dimensional actuality.

Just because I may not have a better explanation yet, does not make the generally accepted theory true.

The world was flat once too....

Know whatta mean?

Because there is no such thing as absolute TRUTH just as there is no such thing as absolute SPACE or absolute TIME.

You're responses come across to me as being quite defensive.

I'm just trying to offer the best understanding I have of the subject.

You seem to be rejecting the main ideas, yet I haven't seen where you've offered any alternative ideas.

But if you stick with it long enough you'll eventually understand why it has to be so.

Physicsts in general aren't that stupid. Relativity has survived an onslaught of rebellious physicists since it's birth in 1909.

Moreover, you had spoken about 'other directions' that spacetime could be bent. Yet you haven't suggested what 'directions' they could be?

You make these comments, but then never follow up on them to explain what it is that you're even attempting to suggest.

I agree Abra.For Creativesoul, to resist a theory or fact because he can't grasp it is understandable.

But Creative is analytical mentalist thinker and I am an imaginative and intuitive thinker. That alone always puts us in a different book. He zooms in on the details and I zoom out and look at the whole because the details only confuse me. Creative can't see the whole because he is caught up in some detail he can't get past.

Like Michael suggesting another dimension that space might be warped...

Otherwise, I'm just babysitting a daydreamer who's groping around in the dark without any clue at all where he might be going.

Creative I don't think it was fair of us to flat out say because you don't except some facets of these theories that you don't understand them, although abra is right, this is exactly what every physics student goes through, myself included.

There were actually several things you said, but I think the following is probably the best one to point to when taken out of context.

Observations do not make the explanations of them true.

Of course the mathematics fits, it has been designed around the notion that the concept is true.

In short the claim is this...The Laws of Physics are the same for any and all frames of reference. It has to fit...lol

I don't think you would have ever made that statement if you truly understood time dilation.

Because it's not space-time. It's spacetime.

"In fact, it's the curvature of the TIME aspect of spacetime that makes gravity WORK.

Time dilation is what makes gravity work!

Okay then, Creative, if there is a "direction" in which space can curve, how would you describe that direction? Up? Down? Left? Right? In? Out? Above? Below? 30% to the right?

Aren't "directions" relative to something??

What would you call the "space" above the sphere?

How would you locate the "top" of a sphere?

Where is up or down?

My question would be this: Is there only one sphere or is there other matter present?

If there is only one sphere, then the energy of that sphere is probably WHAT determines the "direction" of the curve of space, but even so, how would you describe or identify the direction?

Do you blame me for "dismissing" this question?

How would you even answer it, even if you knew the answer? Care to take a stab at it?

The nature and energy of the sphere determine the "direction" (however you decide to describe this direction) of the curvature of space.

Now the next question that should follow is HOW?

I dismissed the question because it seemed like a pointless question given that the description of a direction without any points of reference would be a little difficult to name. Do you know a way to identify a direction with no points of reference?

Do you know where the top and bottom of a sphere would be? Left or right? etc? If not, then what does it matter what determines a the direction of the curvature of space if you have no way to identify the direction?

A better question might be what determines the shape of the universe or the shape of known space-time.

I think you're missing the point worrying about length contraction and/or 'points in space'. That's back to thinking in terms of an absolute space out there in the Newtonian sense.

Just focus on time dilation ONLY. Once you truly understand time dilation intuitively then you're home free with all the rest of it. You need to understand time dilation so well that you can imagine experiencing it.

And again. Physics and Einstein's GR don't say WHY time dilation occurs. They simply say that they do indeed occur, and have been experimentally verified to be a real property of the universe in which we live.

What determines which direction space-time distorts???

Really? You want a plausible explanation?
First, space does not "respond" to the presence of matter. Without matter, there is no space.

If you can imagine a condition where there is no matter (including anti-matter and or dark matter or matter of any kind seen or unseen) then you would see that what is left is not space, curved or otherwise. What would you imagine is there then? Nothing? A flat surface? A void? A vacuum? A black hole? I don't know, but it would not be a three dimensional or four dimensional "space."

If a beam of light is traveling past me while I am moving at 99.9% the speed of light, then what speed is the light beam moving past me from my frame of reference?

Dont time and space kind of "stretch" to make sure nothing goes faster than the speed of light? Time can flow at different rates and even space can stretch for different objects.
