The Universe is infinite has always been and will always be

and is unchanging in time.

“The Universe is

Static and Eternal”

Einstein’s Equations

LEFT-HAND = RIGHT-HAND SIDE SIDE Curvature = Energy-Momentum

Gµv = 8πTµv Gµv - Ʌgµv = 8πTµv Cosmological Constant

“I love hearing that lonesome wail of the train whistle as the magnitude of the frequency of the wave

changes due to the Doppler effect”

Red Shift = Velocity

1.5 x 109 years !

Einstein’s Equations

LEFT-HAND = RIGHT-HAND SIDE SIDE Curvature = Energy-Momentum Gµv - Ʌgµv = 8πTµv

Gµv = 8πTµv + Ʌgµv

THE WORST PREDICTION IN ALL OF PHYSICS!!

Weighing the Universe

Ωm = 0.30±0.01

Ωm = 0.30±0.01

Anthropic Principle:

"Conditions that are observed in the universe must

allow the observer to exist“

-or-

The Universe looks the way it does because we’re here to see it.

Einstein:

“What really interests me is whether God [sic] had any choice in the creation of the universe”

“Eternity is a long time, especially near the end“

“Things are going to get unimaginably worse, and they are never, ever, going to

get better again!”

Fund Cosmology NOW !

The longer we wait, the less we will see

if ≈ 6x10-30 g/cm3 RH ≈ 1.7x1026m ≈ 18Glyr

No evidence of the Big Bang !

Hubble Expansion = disappears

Dark Matter = disappears

Dark Energy = disappears

CMB = disappears 1/2 ≈ 1 kHz

“The Universe is

Static and Eternal”

Some Cosmic Humility

We live in a very special time:

The only time when we can observationally verify that we live at a very special time!
