But we know that plant food (CO2) is going to kill us all........./s

[minnesota_bound]

I am going out on a limb here and say it is expanding pretty darn fast.

Who said the universe is infinite? How do they know?

“But, but I thought science knew everything. So sayeth the Democrats.”

I know the head of the physics department at the local college. He’s lectured at Fermilab. He once told me that every scientific “fact” should be prefaced by the statement “At our present level of ignorance we assume that.......”

This story fits with the youtube ufo stories

[HandyDandy]

It’s all relative.

[MtnClimber]

Really?

Who said the universe is infinite?

I was about to ask the same question...

There may be an infinite number of universes, but that too is conjecture.

But we know it is caused by man.

[Henchster]

“Who said the universe is infinite?”

NASA has been telling us that forever. Probably because they don’t want us to know what’s on the other side. {:^)

[dfwgator]

"This is too much!"

“L. Ron Hubbard”

Just another Howard Hughes-Timothy Leary sort of wannabe.

[rottndog]

NASA....Truman Show directors....

[TruthInThoughtWordAndDeed]

It’s not.

[equaviator]

When you hot, you hot
When you cold, you not

[MtnClimber]

It’s all relative.

You may be right. We my not know all the variables in what we think are constants.

Hundreds years from now Scientist will look back and laugh at out ignorance.

Probably something that will be repeated every few hundred years. Two hundred years ago was 1817. What did we know then? We did not even know about galaxies.

[Ray76]

Expansion takes time. Maybe time is an illusion.

[HandyDandy]

We don’t even know what Gravity is. I was amazed to read in the article that we have only been aware that the Andromeda Galaxy is outside of the Milky Way galaxy since 1932. I was born into a world that readily accepted this. It wasn’t even known at the time my father was born.
