Where is the center of the universe?

A logical necessity since if you tried to send some type of gravitational signal you would no longer be a static field. However moving static fields allow the precise determination of their position, mass, velocity, and direction of travel, assuming you can track the magnitude of the field at different positions and times. That way you can get out of the way of that big boy before it comes crashing in. It wouldn't do much good to try and communicate with an asteroid anyway. Note the shape of the object from your perspective, even if it passes, could theoretically be calculated. If the object had spin you could even get a 3d profile. I am wondering if the resolution of the measurements would be limited by the zero point energy on the interferometer reflecting surfaces. I believe there is however a logical question if non-symmetrical rotating objects generate a static field.

I'm not sure a massive object coming towards you is an example of a static gravitational field.

If it's not accelerating or rotating I think it would have to be. Else you would have to pick a preferred initial frame of reference (namely yours).

Some questions do not have logical answers. We should consider the universe is created as it is and expanding rather considering it originated from a center point. Every point in the universe if a creation point and further looking for logical answers would confuse the physical theories itself.

Don't forget - those who have all the answers also have all the questions. So further looking wouldn't be helpful.

Uh ... HUH ?

Is there any physics in whatever it is you just said?

bmehmud

Ok. How this big bang originated. I want a logical answer involving the 'physics' what you know.

Drakkith

We don't know. Just like we don't know how to make Fusion power work. Or any of a thousand things we know that we don't know.
We CAN say that the universe was once in a very hot very dense state and expanded outward from there. We can extrapolate back in time to a point very close to where the big bang is theorized to have occurred at, but beyond that we cannot say as our model breaks down.

bmehmud

That is not a logical answer not physically proved. You are saying that universe 'WAS' once very hot dense state or we may say 'singularity' BUT from where does the singularity came from? who created the 'singularity' and how this 'singularity' got infinite density? what is density by the way? who created the matter? when the matter was created? giving the accurate calculation time of creation of matter? what is time by the ways? who created the time, space, matter and after all the 'physics' and its principals as we say AND the mother of all questions "How this all is created by itself"?

phinds

YOU ARE NOT LISTENING ... as drakkith pointed out, we don't know. Get over it.

Drakkith

I already answered your question on the origin of the universe. We do not know. The state of the early universe is a much different story. Our current model describes it very well. It is both logical and proven according to current observations. It would be illogical to disregard simply because you don't want to believe it or don't know anything about it.

bmehmud

Yes I am listening that is why I asked the question. Simply quoting "We do not know" is proving my point here. I want to believe if I get a logical answer. If you do not want to answer is another point. Thank you guys.

This seems beligerantly redundant, no offense. If your point in the first place was to prove that physics isn't sure about what created the universe, your point was proven already, (by physics).

You asked a question, you got an answer, and frankly, that answer IS backed by all the physics we know. It may not be the answer you want per sae. Hell, I hated finding out that distant galaxies are receding FTL, meaning we, in our current state of progress, will NEVER see those galaxies up close and as they are now, not as they were 47 billion years ago or however long it took for the light to reach us.

We observe the universe as is, (it's expanding, use whatever term you want), and when you reverse that whole aspect, you end up with everything closer together. Singularities don't make any sense, that is why people will tell you they just don't know. Best guesses based on today's understanding is that yes, we were once more compact, and something made us start to be less compact. Dark Force? The great turtle holding us all up on his shell farting after eating some bad cabbage?

I can make up something more creative that is logical and deals with physics, but it's no closer to the truth than the singularity. That is just the result of extrapolating what we know of the universe back as far as it goes. And typically, in physics, a singularity means we don't quite know what happens, because our math breaks down.

You clearly don't have a point other than "God did it", which of course is unscientific garbage. It's certainly not implied by the things we know. The "big bang" is a feature of a few different theories of space, time, matter and motion. None of those theories make any claims whatsoever about what, or who, created those things in the first place. They don't even involve the concept of creation in any way. There are no theories of creation.

SHISHKABOB

saying that we don't know doesn't prove anything other than the fact that we don't know. Someone saying that they do know how the universe was created doesn't prove anything other than that they are saying that they know how the universe was created. Nothing can be proved in this situation because there is no data about it.

Ok maybe this is just too much for me to understand. I try to look at everything in its simplest form. If you were able to travel beyond the limits of the universe (if there is such a thing) and look back on it would it not have a geometric shape? If so, wouldn't that shape have a center point? Whether or not it is expanding or contracting it still has a shape. Unless you know the physical dimensions you can't calculate it but it still has to have one. It's my uneducated opinion that one day we will gain enough knowledge about the physical universe that all the knowledge we have now will seem like stone age nonsense. I appeal to all you free thinkers out there. Don't let the so called scientific authorities tell you that your ideas are wrong or impossible. The earth is not really flat!

Did you take a look at my links to the hyperspheres?

Just in case you didn't, just google Hyperspheres and you can see how you can move around through one without seeing a center.

The universe is all-encompassing, there really is no "going beyond the limits to get a look at the over all shape" since going beyond any limit would still put you inside the universe, since the universe is everything. Just like the one dimensional being analogy. If you lived on the outside of a 2 dimensional circle, you could only move forward or back. You wouldn't even know there is a center, because you would have to be 2 dimensional to see the circle at all. So with that in mind, where is the center of a circle when you only live on the edge, only able to go forward and back?
