Hello Orca What logical traps? Well, it all goes back to Newton and before, when they were kicking around the idea of gravity and a static universe. Now this is before they knew about galaxies. The mind experiment went something like this: if you have an a static universe full of stars, gravity wou...

The first part I garee with, but not the add on. What does smaller mean in an infnite universe. Is the universe infinite? Is it also static? If so how does it avoid gravitational collapse? Remember, even before Newton this was a struggle...people 'wanted' the unvierse to be infinite, but there are ...

Mate, If you think that the Big Bang is it so be it. By next year the theory will be exposed. Its onlly a matter of time. Exposed? You make it sound like a conspiracy! :-) If BBT is found to be inaccurate, and the tests that prove it to be inaccurate can be replicated throughout the community, then...

Hello Orca You are assuming that there is a start to all this and that the BBT is correct. In my opinion, there was never a start and there will never be an end. Just a process of recycling and evolution of stages and phases of the objects within the universe. But! you statement maybe correct withi...

Me too, harry.. Though it seems to me that it would be really weird if gravity didn't propagate at the speed of light. After all, the other 3 forces have been unified...somewhat...the electro-magnetic force and the weak force were actually referred to as one electro-weak force in one of my textbooks...

Astro, it just doesn't seem like it adds up! :( The Chandrasekhar limit is only 1.4 solar masses. While it is true that many stars that have much more mass are able to lose enough of it, usually you can see some trace of it, like a planetary nebula or remnants of a supernova. Shouldn't the Sirius sy...

Sirius B (APOD 6 Oct 2000)
Sirius, the brightest star in the sky, is in fact a binary star system. There are two stars...Sirius A, a main sequence white-blue star, and Sirius B, a small companion thought to be a white dwarf star. I never thought much about it...but something occurred to me of late. Why would a white dwarf be ...

The universe has no edge in what ever logic you use. If you use man's maths than maybe space/time is a derivative, but ! time, actual time cannot be changed. Cannot be lengthen, shorten or given different dimensions. You just as well prove that santa clause is true. Time is relative. Time moves mor...

Again -who the heck is the IAU :roll: We can reject their decision and set precedence for future attempts. Seriously –Pass it on “R-E-J-E-C-T-E-D”!!!! Political agendas should not enter into astronomy. It took us too long to overcome religious agendas. That is my final say in this matter---Just say...
