Default The Cooling of the Universe

Tests of Big Bang Cosmology

The Big Bang Model is supported by a number of important
observations, each of which are described in more detail
on separate pages:

1. The expansion of the universe
http://map.gsfc.nasa.gov/universe/bb_tests_exp.html


Edwin Hubble's 1929 observation that galaxies were generally
receding from us provided the first clue that the Big Bang
theory might be right.

2. The abundance of the light elements H, He, Li
http://map.gsfc.nasa.gov/universe/bb_tests_ele.html


The Big Bang theory predicts that these light elements should
have been fused from protons and neutrons in the first few
minutes after the Big Bang.

3. The cosmic microwave background (CMB) radiation
http://map.gsfc.nasa.gov/universe/bb_tests_cmb.html


The early universe should have been very hot. The cosmic
microwave background radiation is the remnant heat leftover
from the Big Bang.

These three measurable signatures strongly support the notion
that the universe evolved from a dense, nearly featureless
hot gas, just as the Big Bang model predicts.

Cosmic time is not relative to our extremely limited existence.

You and others of your mainstream closed mindset kind can't even tell
us what year Earth got its seasonal tilt or the Arctic ocean basin.
In fact, you can't hardly explain anything of how humans even came to
be.

The only cosmic things proven lately is that the universe and our puny
galaxy are anything but consistent or in any way unified. At least so
far, there's not even an identical star to that of our sun.

I guess this depends on your definition of 'identical', because there are many that are 'nearly identical', and it is just a matter of time before one is found...

Stars like our sun have come and gone billions if not trillions of
times by now.

Each and every stellar creation is one of a kind, unless intelligent
design gets involved...

No disagreement with the above, of course, nor the reasoning below
that I've snipped.

receding from us...


It was V. M. Slipher who provided the radial velocities, though
Hubble is often incorrectly given credit. What Hubble actually
provided were the galaxy _distances_. (The web page cited is correct
if you read it carefully.) By plotting velocity against distance,
Hubble discovered that recession speed is proportional to distance.

I agree.
