Where was the epicentre of the big bang (universe) in relation to us?

[CheeryTulip]

Just curious Behind the sun or behind Pluto?

When we are in which position relative to the sun?

Following. Literally obsessed with anything to do with space so hoping this thread gets lots of replies and I learn lots more new mid-blowing facts.
I still cannot get my head around the fact that space doesn't end anywhere that it's just infinate. Honestly the concept is just too much for my mind to understand.

Everywhere, in front, behind, whereever.....😊

I realise now I based my question on the image of our planets in a row but of course they're rotating around the sun

I'm looking forward to the release of new photos next week by NASA of the furthest reaches of the universe yet seen.

Are you confusing the solar system & the universe because Pluto orbits the sun, so there are times when the sun and Pluto are in the same direction and times when they are opposite.

Remember the Big Bang proceeds a rapid expansion in space, so it's not that we have moved away from the epicentre but more that that tiny dot that was before has grown bigger to become the whole universe.

Omg my mind's blown by that @notimagain

That's me 🙋‍♀️ Centre of the universe right here!

One of the few cosmology things I remember is the currant bun concept. Pick a currant, while expanding in the oven it will see every other currant moving away from it. That's why light had redshift in every direction into space and not blue. (something like that).

This is bloody fascinating. I heard someone say recently, that the further out you go, the faster everything's moving away. At the time I understood it but I've forgotten now. And if the big bang came from a dot, what put the dot there?

What's scary, is the space charts, when you zoom out and realise how much outthere, there is, and see that our universe is just a small dot on the fabric of space.

<lurks in fascination>

I love thinking about all this. Totally blows my mind.

Now, I know that the big bang kicked everything off. There was nothing here before then: no matter, no space, nothing.

But ... what happened? How did something come out of nothing? Why did the big bang suddenly happen? Why did it happen right then? Etc etc etc ..... 🤯

OMG

I don’t believe the Big Bang Theory. It is just a theory anyway. Its not like a law or anything. I rather think we have matrices/vast networks of universes and that black holes & white holes connect them…so the matter going into a black hole, comes out a white hole in another universe. When one universe collapses because it has more black holes than white, a new universe is created by the excess black holes…resulting in matter expanding into a new universe that then has stars that then supernova that then create black holes and connect it up to other universes. As for what was the first universe/origin of universes, haven’t quite worked that out yet. But I suspect there was no first/origin because time isn’t really linear. Time is more like a spring folded into a möbius loop.

Except it doesn’t redshift everywhere. There are over 100 galaxies (and their billions of stars) that are blueshift. The Andromeda galaxy for example are blue shift and thus moving closer towards us,

It doesn’t work like that; it was everywhere.

That’s not what “theory” means in science.

A theory is a well-supported model of how the universe works. The scientific equivalent of what you mean by theory is a hypothesis.

There is a lot of evidence supporting the idea that as we turn the clock back the galaxies were much closer together, and we see the echoes / ashes of the Big Bang in the microwave radiation background.

I’m not a cosmologist, but was a physicist when younger.

I've importantly googled it and the consensus is there was no epicentre

And this is based on...

I know what a theory is thanks. It’s still not a law. It’s between hypothesis and law. We do know that Big Bang Theory breaks a few laws by positing that we are creating matter/energy, and rather a lot of it, out of nothing. It also, I think, is a sciency retelling of Genesis when you strip back the narrative…which essentially states all this comes from nothing. The only thing different is that instead of a God creating out of nothing, it’s some wierd ass explosion.

True, galaxies orbit about each other and some were closer together, but others were also farther apart….take the 100+ that are blueshift for example. True, we see background evidence of matter moving at different speeds/dark matter & entropy. But just because we have evidence our universe was ‘born’ and will eventually succumb to entropy/back holes and “die” doesn’t meant it was created from nothing nor that it is the only universe. I’m not denying the data, but rather the (convenient) matching of that data to what is really a more modern creation story.

Rumour has it that Brian Cox’s wife is on here. Maybe he could swing by and fill us in.

Have you published your theories anywhere? I'd like to read them.

No, none of that is right. Galaxies do not orbit each other, and a law is not “above” a theory, it’s a different thing; laws tend to be very simple facts such as conservation of momentum or the speed of light.

The current theory accords with all known laws, it is not positing that energy is being created.

When I was doing my doctorate I would often be sent unsolicited “theories” like @Discovereads above, from people who didn’t have a background in the subject but just didn’t feel like they liked the science.

I’d read some through, but like the above one they were just supposition, and didn’t match the data.

I think it was Pauli (happy to be corrected though) who described idea like this as “not even wrong.”

A bunch of physics reading. White holes exist. As do black holes. No one knows where the matter goes in a black hole or where the matter comes from in a white hole. So it is reasonable to think perhaps it’s the same phenomenon but one end is the mouth and the other the arse end. We know they are massively supercharged compared to wormholes that only bend space time within a universe so why can’t the black/white holes not be essentially giant wormholes between universes? They both bend space time, they are both structurally the same. Theres a lot of physicists that think multiple universes exists- Stephen Hawking was one. Similarly, some leading physicists have also posited that time is not linear.
