The Evolution of the Universe

In the beginning, of this cycle, all (or almost all) the matter of the Universe collapsed and then exploded. The outer layers of the explosion were ejected at the fastest velocity, leading to what we still see today -- the observation that the stars and galaxies that are the most distant from us are...

Re: Spiral Galaxies

Thought experiment: If the Universe started with a homogeneous distribution of the same type of atom except one that was heavier than the rest. If the atoms were equally spaced (pun intended) from each other except for the one heavier atom. That one would attract surrounding atoms. If the surroundin...

Spiral Galaxies

I recently read that 72% of galaxies are spiral. I asked myself why are there so many and how did they form. After thinking about it for quite some time, I came up with the following: In the beginning, of this cycle, all (or almost all) the matter of the Universe collected and exploded. The event d...

Big Bang Cosmology Meets an Astronomical Death

Re: "Newtonian Explanation of Galaxy Rotation Curves Based on Distribution of Baryonic Matter"

At first, when I read this 'paper,' I thought it was a hoax, but I'm a long time skeptic of 'dark matter' and MOND seems to be just a tweak of the math like a tweak of the epicycles when the observations got better. At least MOND didn't involve inventing VAST amounts of some kind of 'invisible' matt...

Re: Galactic Distance Ladder

I used to think that distance measurements were dependent on parallax, variable stars like Cepheids and redshifts. Now that I have the time to study those methods I found this: https://en.wikipedia.org/wiki/Cosmic_distance_ladder I'm interested in all those measurement techniques. I once read that t...

Re: Newbie looking for suggestions

My 20 cents worth (inflation you know). I think the hardest part of being a beginner is finding things in the sky. Therefore, I recommend a Meade ETX or something similar. The tube and tripod is very portable. It has a semi-automated alignment and after that you can select what you want to see on th...

Re: I now understand Pluto's place in the solar system

After watching the video I would describe the solar system as:

- Four inner rocky, dense objects that dominate their orbits

- Four gas giants that dominate their orbits

- The Kuiper Belt of which Pluto was the first to be discovered

- The Oort Cloud

Re: Dark Matter doesnt exist? Onto something or on it.

Take a look at a book by John Moffat, "Reinventing Gravity." He adjusts the law of gravity so we don't need 'dark matter.' I have tried to discuss the possibility that there is no 'dark matter' with a physicist, but since all the money is going to those who are trying to make it work, ther...

I also would like to support a local store, but I ordered a Coronado P.S.T. and it took them 10 weeks to deliver it. It was suddenly delivered 3 days after I threatened to cancel the order.
