Is the Universe very big? - Page 2

I have been thinking.
My questions are for the sake of discussion.
If we took inflation out of the model and allowed an expansion rate at the speed of light would that time be long enought for everything to, as simple as I can put it equalise by internal machinery which would dictate although not related touching whatever could reach a universal equilibrium.

Excellent post Alex

Whilst I have always struggled with size and distances in the universe, I find it much easier to tackle the time side of it.
Almost every physical thing I have encountered or read about in my finite physical life has a beginning and an end, not always first or final though as things can be formed from something ( beginning ) and change to something ( end ) and so on it goes.
The time related to this seems to me to be the the big ticket.
In less than than a week, this Thursday night I drive back to Brisbane to see my new grandchild and then bring my better half back to the coast before this Sunday. It is not the distance that is relevant to me but the time it takes.

If I owned a Lear jet on a property that had an airstrip and likewise the same for my son in Brizzy, I would be there and back every 2nd weekend, with just a few hours each way travel time against 9-10 hrs driving.
What has changed, not the size of distance, but the means that we compress travel time between the two locations.
I spent near 38 years commuting to and from Sydney at a general minimum 3.5 hours door to door per day. What a difference had I been able to step through a portal to work. No distance or size but the time it takes for a step each way.

I have not been able to find it since, but quite a few years ago I read a news paper extract of an article that I think was called ‘ Curtains of Perception ‘

In short and from memory, it goes something like this.
Early in human history a tribe lived in a large valley and knew nothing beyond its ridges. One day one of the tribe walked over the ridge and met an unknown tribe member from the other side.
Their perception of their worlds changed at that point for ever.
We move onto horse, boat, plane and rocket to find out just how big our world is and how small our perception was.
This pails into insignificance though when we discovered the electromagnetic spectrum and the means to read and use and measure it. Newtonian telescope to radio astronomy and computers to master them.

Is the universe very big?, I just am marvelled when each curtain of perception is rolled away to reveal just how big my world really is and how small it really was.
Next curtain!!! gravitational waves perhaps!!! Surprise me.
That’s why I look at the stars and wonder and wonder and wonder.......

Alex are you talking about this universe that we are in or the billion other universes one of which spawned this one?

My guess is there are 'Big Bang' events going on continually, being spawned by the collapsing of other older universes into singularities and then propagating a new one.....

(Prove my theory wrong, I dare you

)

We haven't apsolved Mercury orbit yet, and big question is why there is NO blueshift recorded.

Hi Steve
Thank you for your kind complement.
I have decided to buy a camper van so that I never have to leave home.
A pier inside with a mount under the dining table a scope under the bed.
Have ever heard...it is a wise man who can imagine a stick with no ends...and the answer is not a circle...try thinking about that ...but not while driving.

With respect you have a hypothesis a theory is like set in stone...
However on another site there is a nice chap who posts his hypothesis and that is his approach...he calls it the spongey universe.

Well that is entirely political.. so much is funded by republicans they control the recorded red shift and they dont want any blue shift recorded.

Blue Shift - is that polite speak for BS?

Looking into TheTheory of Special Relativity is would seem due to the constant C although there should be a blue shift there wont be any observed blue shift...its all tied back to observers observing C as a constant.The same occurs with Red Shift we dont observe it because of the aformentioned rule applying to observation of light and what we observe is just red dust...its everywhere in the universe all left over from the iron wiskas hypothosis ...why it oxidised we dont know...I am working on it but its not the only thing...and there is that box that the oxeygen goes into..
And that is unprepared...I see a speaking circuit ...
I recon I could spin it with the best of them.

Lots of observed blue shift in Canberra.

There can not be any blue shift, because we are at the centre of the universe and everything is moving away. Where else would life form but at the center of the creation of everything?

LewisM · #33 31-01-2018, 11:18 AM

Life is infinite and eternal - but a person lives but once.

Carbon based life form indeed.

To continue to believe in the Big Bang singularity in an infinite space is absurd. Perhaps in our observable cosmos, yes, but to assume there are not repeated and continual events such as this gigaparsecs away is denial of the obvious. The Big Bang assumes every single atom condensed at a single point - a point that has no centre, no end...and there was a great attractor to condense them in the first place, which came from... yes, our human brain cannot fathom the Cosmos.

Sorry, Big Bang does not work, but it continues to evolve as our understanding progresses. We will and can NEVER know.

You can't just leave a statement like that hanging there without explanation:

a) What are the unresolved problems with Mercury's orbit that haven't been addressed yet?

b) What is the problem with a general lack of Blue Shift? (It's not correct to say that there is NO observable blue shift, but red shift is far, far more common, as would be expected in an expanding universe.)

a) For sure it is Planet X / Nibiru causing fluctuations in Mercury's orbit

b) because, somewhere someone considers it a conspiracy, probably perpetuated upon us by NASA

Wonder if Mad Mike The Rocketman will launch to try to see the curvature of the universe next...or is that flat too?

I think the Universe is described as flat.

Nearly everything we perceive as being the "solid" part of the universe is just an illusion created by energy fields around impossibly small particles called Nuclei ( Nuclei are around 100,000 times smaller than the atoms they’re housed in). So the universe is pretty much just energy. Here's a strange but different idea about what might be happening. https://io9.gizmodo.com/5876966/what...-particle?IR=T
What is time anyway, for me it's always just now.
