> The Big Bang Hypothesis - which states the universe has been expanding since it began 14 billion years ago in a hot and dense state - is contradicted by the new James Webb Space Telescope images, writes Eric Lerner.

> It is not too complicated to explain why these too small, too smooth, too old and too numerous galaxies are completely incompatible with the Big Bang hypothesis. Let’s begin with “too small”. If the universe is expanding, a strange optical illusion must exist. Galaxies (or any other objects) in expanding space do not continue to look smaller and smaller with increasing distance. Beyond a certain point, they start looking larger and larger. (This is because their light is supposed to have left them when they were closer to us.) This is in sharp contrast to ordinary, non-expanding space, where objects look smaller in proportion to their distance.
Smaller and smaller is exactly what the JWST images show. Even galaxies with greater luminosity and mass than our own Milky Way galaxy appear in these images to be two to three times smaller than in similar images observed with the Hubble Space Telescope (HST), and the new galaxies have redshifts which are also two to three times greater.

I'm not surprised that the first analyses of the first Webb data seem to indicate that galaxies in the early universe are more massive than the standard model of cosmology predicts.

Scientifically Accurate Twinkle Twinkle Little Star

Twinkle Twinkle Little Star
I know exactly what you are

Opaque ball of hot dense gas
Million times our planet’s mass
Looking small because you’re far
I know exactly what you are

Atmospheric turbulence
Causes rays of light to bend
Blurry light gives views subpar
Causing twinkling little star

We see you as if in the past
Light’s not infinitely fast
Lookback time delays our view
I know exactly what you do

Fusing atoms in your core
[1]Hydrogen, helium, carbon and more
With such power you shine far
Twinkle twinkle little star

Classed by their spectroscopy
Types named O, B, A, F, G…
Bright when close and faint when far
I know exactly what you are

Smallest ones burn cool and slow
Still too hot to visit, though
Red stars dominate by far
Twinkle twinkle little star

Largest ones are hot and blue
Supernova when they’re through
Then black hole or neutron star
I know exactly what you are

Gravity holds on too tight
Nothing gets out, mass or light
Black holes are the most bizarre
Remnants of a twinkling star

Neutron stars spin really fast
When their beams of light sweep past
Then we call you a pulsar[2]
I know exactly what you are

Our Sun’s average as stars go
Formed 5 billion years ago
Halfway through its life so far
Twinkle mid-size yellow star

Sunspots look dark but they’re bright
Slightly cooler so less light
Temporary surface scar
I know exactly what you are

Swelling up before it’s dead
Cooling off and growing red
Then its end is not so far
Twinkle big red giant star

Outer layers float away
Planetary nebulae
Wispy gas is gossamer
I know exactly what you were

White dwarf is the core you get
matter is degenerate[3]
When small stars say au revoir
Twinkle very little star

Interstellar medium
Recycled ad nauseam
Gas and dust are spread afar
I know exactly what you are

Forming from collapsing clouds
Cold and dusty gas enshrouds
Spinning, heating protostar
Twinkle twinkle little star

Often forming multiply[4]
Clusters bound by gravity
Open type or globular[5]
I know exactly how you purr

Two stars make a binary
Or a triple if there’s three
Some are solo just like ours
Twinkle twinkle little stars

Two hundred billion stars all stay
Bound up in the Milky Way
Dusty spiral with a bar
I know exactly what you are

Stars have planets orbiting
Rocky or gassy, moons or rings
Earth’s unique with life so far
Twinkle twinkle little star

Watch the tonight.
As soon as it gets dark look a little above the horizon.
