# Earth at the center of the Universe?

First thought is that, as the universe is uniformly expanding from a BB, it means that every single point in the universe is simultaneously at the centre of the BB.
Next thought is that it make a great deal of difference to recognise that as distinct objects neither are at a centre of the universe in relational terms

The reason that we do not consider the earth as motionless with the sun going round it is that objects in the UNiverse would have to transgress the speed limit (speed of light) for it to be true.
This is the difference between geometry and physics.

Because?

Do you know what the “full” story is? How?

Many galaxies speed away from us is speeds greater than that of light. But anyway, NO. Changing reference point does not call for a change in the laws of physics. If something moves in speed X around an object, it does not matter which object you call “center”…

Because “things” like gravity and electromagnetism cannot be seen directly - but are inferred from a large amount of evidence and many many observations. If the planets and the Sun revolve around Earth, most of what we know about space and astrophysics is wrong. Did we land on the moon by an incredible, fortunate accident or is there something that works really well about our current physics models?

No.

It is an ontological choice, not a reality one way or the other.

To a peasant population it is an advantage if the the Earth is at the center of the universe, but to an urban population it is an advantage if the the Earth is not at the center of the universe.

You might have a good point there. One in need of a centering inspiration. The other in need of escape from the noise.

There is a painfully simple reason why the earth is not the centre of the universe IN ANY WAY, as that would mean that the observed movement of the stars would put their velocity well beyond any reasonable expectation of the speed of light.

Science just describes the “how”. And this description is not affected by the center SELECTED. Choose any center you like, transform your equations and you will have exactly the same “physics”.

Not really.
If the earth is taken as the centre, then that implies that the sun goes round the earth, (as the earth rotates) and so too do the stars. If you want to preserve the fact that the stars are far away they would have to be traveling far in excess of the speed of light.

Everything can be considered being at the center of the Universe,would it be earth, any solar system or even a mere subatomic particle. Everything is a fractal of the whole, and thus possesses an element of the whole within. As above, so below.

In the same way that would be a problem for the Sun, wouldn’t it?

However the speed you refer to is not violating anything. Relativity refers to local speed in a system, not speed related to anything in the cosmos.

Try and stop to think about it.

The earth is quite a big place. Which point of it, exactly, is at the centre of the universe?
