Galaxies Underestimated

The quest for knowledge should probably not be limited to practical applications.
No, but it should be limited to the practical application of knowledge, built on other known laws, which are well known and well established. It is foolish to find a way to do something that is known to be impossible.
Do we know how long galaxies exist? I don't think we do
I agree. If observation and replication is the mode that proves anything.
The value is that these new finds run counter to the cosmological principle and that we need to recognize alternative hypotheses.
I always found it odd that there are so many like bodies out there, like planets for example, but no "half planet" or "star in the making".

The big bang for example, at least in a simple context......an explosion......I have seen enough explosions to know that as the debris leaves the genesis of said explosion, the amount of matter per square ft (as example) gets less and less dense, not the same in all areas with even dispersion. Of course, explosions do not typically create anything, but make them less complex. Entropy. This would suggest that the universe would have been most complex at its beginning, and as time moves on, things would be less complex.

If all things in the universe would be the same at all times form all perspectives, I just cant make out how all these galaxies would be in the same state at the same "time".

I may not fully understand the cocept.....but, there seems to be a contradiction.

Interesting.
 
The math doesn't support that analogy /
We are significantly smaller than a grain of sand /
There are roughly 26,000 stars out there for every single grain of sand on Earth /
If you scaled the entire universe down to the size of our planet, Earth would just be the size of an atom /
Most intelligent response in this thread. Nice.
 
No expert here, but in modern physics, in my experience, there is just no meaning or expectation that anything is going to feel right. The exception is 0W8 oil, which does not feel right to anyone.
Unless made by Redline Oil or High Performance Lubricants I completely agree. Better have a hths of at least 2.6
