Right this makes sense now.
And would this mean Hubble radius and Hubble time are inverse of each other as well? So Hubble radius has been increasing while Hubble time has been decreasing?
I still don't think i catch your drift marcus. Sorry for being stubben i just want to be 100% clear.
So Hubble constant is the measurement used to describe the expansion of the universe. And Hubble Time is how old the universe is, but things like inflation and dark energy make it more than it...
I remember an analogy which said that you can't teach a dog physics, it can't comprehend physics. Likewise we might not be able to comprehend physics to an extent.
Also is there an exact conversion we could just times the Hubble constant with to get the km/s per Mpc units?
I was playing around with some numbers and got 9.78x10^2. It isn't exactly precious so was wondering if there is one.
Thankyou both. I did get a bit confused. My reasoning behind my question was that i know the universe has been gradually expanding faster and faster. And i believed that the Hubble constant is the rate at which the universe is expanding (67.9 Km/s per Mpc). Wouldn't this mean that the Hubble...
Same here.
I also tried for 0.473 billion years where Ht was "1.0176"
∴ H = 1/Ht
∴ H = 1/1.0176
∴ H = 1.407459536
And when i place "1.407459536 per billion years in (km/s per Mpc)" in Google i get this (screenshot):

I have made up my mind about buying a telescope. The one i will be buying is:

But i do still have some questions. This is my first telescope, will it be easy for a new...
I remember reading an idea about universe bruising as a way in which we could proof multiverse. I believe the basic idea is that if another universe would collide with our own we should see some kind of effect or 'bruising' according to the source i was reading it from. I'll try and find it and...
In a way yes. but was mostly looking at all the statistics of the stars from 10 billion years ago compared to stars 5 billion years ago. But The Hertzsprung-Russell Diagram helped to separate them in groups and i just searched them individually :)
Sorry if i was a bit unclear on the wording i used. The Hertzsprung-Russell Diagram seemed very interesting and something I'm looking furthering into now. Thankyou very much!
Just been looking around for any good resources or databases which show history of stars in the universe. I have mostly been looking into the size and chemical content of them (like those of population I, II, III). But just looking for some real data and numbers to go with it, like star sizes...
I was woundering if the terms "Northern Hemisphere" and "Southern Hemisphere" (of the universe) are used a lot in either an astronomy or astrophysics concepts? Because i have see both those terms being used to describe some ideas for the universe, and i was woundering if anyone could give me...
Hello, I've been looking round trying to find a history of records, showing the speed of which the universe is expanding? Would this just be the hubbles constant? If so I'm looking for past Hubble constant values. Is there an archive for this? or is there a way to work past Hubble constant's to...
Thankyou Markus!
Is there anyway to find out the density of different parts of the universe? For example is the density in the northern hemisphere of the universe bigger or less than the southern hemisphere? I would think they would be different because the universe isn't uniform, because we...
