Science: The Hubble and Redshift

Is this cool or what?

Measuring the redshift allows astronomers to figure out how fast these entire galaxies are rushing away from us.

The Big Bang — it's not just commonsense. It's the LAW!!

OK, that was gravity, but in these dark times we need to focus on science to draw us out of the bleak Armageddonish view of the future being promulgated by rightwingnuttia. Carl Sagan was right. "Billions and billions of stars ..." Just waiting for us to explore them all.

I hope this loverly post means you're doing well - I've been so over-extended these last 2 weeks or so I haven't had a chance to come by and check up on you! How are Los Gatos, whom I love long distance?? (Kinat?) (Sounds sort of Hebrewish, maybe?)

Lies! The work of the devil, don't believe it, I know because Rush and Sean and Bill, et al. told me so! The earth is only 6000 years old and is the center of the universe and all the other stuff is fakery.

Yeah, I can just hear the stupid wingnuts now.

I have to tell you Q that this little video filled me with awe and wonder. It is soooo beautiful. I love it! And even though I am an evil non-believing atheist, that video was very spiritual for me. It filled me with a sense of connection with the universe and that is truely beautiful! Thank you!

Lizzy, hi! I've been by a few times, and see you're back to blogging! Haven't commented though. I am doing well,thank you. Life is a little tough as I am forcing myself to get up and move around as much as I can, which means pain, which means drugs. And reading about war. Which is awfully depressing. But the kitties have been comatose from the heat, which means they're NOT getting in trouble and destroying things.

Kinat is Arabic for something, but I forget what. So much for memory and language. Don't use it, lose it.

FoTPC, isn't it beautiful? Science is just SO cool, I can't imagine why people would need anything else, like fairy stories.

Me either! You said it TPC!

Tony Darnell (the narrator) states that some of the galaxies are moving faster than the speed of light. Anyone know how that would be possible?

Hi, SteelyBob,

I don't know, physics not being my area of specialty. However, I should (and will) research the issue and blog a follow-up. Thanks for bringing up the issue.

Yah, physics ain't my bailiwick, either.
I seem to remember that it's doctrine that nothing exceeds the speed of light.
Something like, mass increases greatly as the speed of light is approached. More and more energy is required to accelerate as one approaches the speed of light.
Sorry, Star Trek fans (I'm one of those).
This one assertion that I'm quibbling about (galaxies exceeding the speed of light) does not detract from a really great video. Thanks for telling us.
