Discussion Overview

The discussion revolves around the concept of whether the Earth is at the center of the universe, exploring observational science, the implications of the Big Bang theory, and the nature of the universe's expansion. Participants engage in a debate about the interpretation of observations and the philosophical implications of scientific theories.

Discussion Character

  • Debate/contested
  • Exploratory
  • Conceptual clarification

Main Points Raised

  • Some participants suggest that observational science indicates we are at the center of the observable universe, questioning the validity of scientific theories that contradict this view.
  • Others argue that there is no absolute center of the universe, stating that every observer sees objects receding in all directions, which contradicts the idea of a central point.
  • A participant raises the question of whether the Big Bang had a center, seeking clarification on the nature of its origin and shape.
  • Concerns are expressed about the leap of faith required to accept scientific theories that extend beyond observable evidence, drawing parallels to arguments about the existence of God.
  • Some participants emphasize that the laws of nature appear consistent across different locations in the universe, suggesting that the same observations would hold true regardless of the observer's position.
  • Questions are posed about the implications of backtracking the recession of galaxies and whether this leads to a singular point, with some expressing confusion over how multiple observers can each perceive themselves as central.
  • There is a challenge to the coherence of the idea that every point in the universe can be considered a center, with participants questioning the geometric implications of such a model.

Areas of Agreement / Disagreement

Participants do not reach a consensus; multiple competing views remain regarding the nature of the universe's center and the interpretation of observational evidence.

Contextual Notes

The discussion includes unresolved questions about the implications of the Big Bang theory and the nature of observational evidence, as well as the philosophical considerations surrounding scientific speculation.

Yes, the geometry you used in school is 100% incorrect when you use it in a situation where it does not apply. For example, a triangle has angles that always add up to 180 degrees correct? What about when you make a triangle on a large spherical object like the Earth? Guess what...they don't add up to 180 degrees anymore. Why? Because Euclids geometry doesn't apply to large curved surfaces.

See here: http://en.wikipedia.org/wiki/Non-Euclidean_geometry

The simple answer is that a 'triangle on a spherical surface is not a triangle.

Easily proven by putting it on a flat surface.

I just gave you the standard definition of isotropy that so beautifully fits observation that professional, knowledgeable physicists have conducted. Please pick apart the definition of isotropy and tell me why it is so "obviously flawed". If you want to talk in terms of rigorous differential geometry then it is only fair to do so.

You see I find it hard to believe something which is so obviously flawed.

What is even harder to believe is that anyone could believe it!

Can't really say any more than that, I will have a further think about it,but the more I think
about it the more convinced I am that I am right.

I'm sorry you believe that. It makes no sense to have that attitude, especially when you haven't even made any effort to understand a complicated concept that has centuries of evidence and data behind it. If you only believe things that make sense to you then the world must be a very very weird place full of unbelievable things.

Sometimes you can tell an argumentative person with no knowledge right from the first post. There do seem to be quite a few of them around here, misc. crackpots included.

Pardon me, I hope you are not referring to me.

I have a great knowledge of matters, maths and science.
Best in my year at school and hence I would imagine I am probably better at maths than you.
(based on probability theory).

It would be a hell of a lot stranger if you believed the stuff which did not make sense. :rolleyes:

I will stick with the stuff which makes sense thank you very much!

That is the realm of reality!

I doubt that very much. This thread should be locked now that we know the OP has no interest in real science and only wants to be argumentative.

I have made my case pretty clearly, I have listen to the arguments you provided and pointed out flaws in them.

A number of the points I made have not been adequately addressed IMO.

Would it not be better to let others address those points rather than sweeping them under the carpet?

I am a reasonable guy, my points are reasoned, well founded in maths and science.

What are you afraid of?

If the thread is locked please feel free to post or message me a better explanation.
Saying stuff like "OP has no interest in real science and only wants to be argumentative"
is grossly unfair.

But all that stuff moving away from us, how do you explain that?
The redshift etc?

All the evidence and observation points to us being at the centre.
All of the evidence and observation points to us being just like every other point in the universe. An observer millions of light years away will see exactly the same thing we do: "All that stuff moving away from us, the redshift, etc."

The explosion of space idea is disconcertingly vague it has many problems.
Where did all this space come from?
The explosion of space idea is very well thought out. It explains "all the stuff moving away from us, the redshift, etc." As to where all this space came from, one of the longstanding hypotheses is absolutely nothing. There are lots of signs that do point to this. That said there are other conjectures, but finding which is right (if any) is going to be a bit challenging. What science can do right now is to explain the universe right down to a tiny, tiny interval after the big bang. That's a pretty big accomplishment, don't you think?
Seems to me there are huge problems as I hope I have pointed out, many centres millions of mile apart and apparently no centre at all.
Your "huge problems" are merely arguments from ignorance and appeals to incredulity. These are logical fallacies, the use of which is strongly disapproved of at this site. Don't go there.

The only word to describe that is nonsense!
There is a lot of nonsense out there, but is mostly from people who go "la la la I can't hear you" because science somehow threatens them. This site has a lot to offer to people who are willing to learn. I suggest that you try to learn rather than taking the "la la la, I can't hear you."

I am not doing that though am I?
The problem is the opposite, other poster wants me to stop me hearing you!

So you really can't accuse me of that, that would be be ridiculous.

Yes you are. I gave you the definition of an isotropic manifold and told you to go look up CMB data and see how it is evidence for our universe being isotropic. Obviously you haven't done that.
