Ok, here's one for the cosmologists [View all] clarice Feb 2013 OP

So what's the question? marybourg Feb 2013 #1

question clarice Feb 2013 #4

Actually we can go back a lot further than 1 million years. Cary Feb 2013 #8

google "Hertzsprung-Russell (H-R) diagram" marybourg Feb 2013 #12

Just googled it. WOW !!!! Thanks clarice Feb 2013 #21

Sounds about right. cleanhippie Feb 2013 #2

What makes you think we would know the "current" nature even if we saw the light instaneously? Cary Feb 2013 #6

We could take that conversation to the philosophy group. cleanhippie Feb 2013 #31

There's not that much difference between philosophy and physics these days. n/t Cary Feb 2013 #37

How so? cleanhippie Feb 2013 #40

Ever heard of Schrodinger's Cat? n/t Cary Feb 2013 #45

The OP was a question about not knowing the true nature because we "see" light through time & space. Cary Feb 2013 #39

So, following this logic... clarice Feb 2013 #7

Certainly possible, and depending on its age as we see it... cleanhippie Feb 2013 #32

There are a lot of things we will probably never know. n/t Cary Feb 2013 #3

All true! We can't know the current nature of the star--only it's past nature. That said... Moonwalk Feb 2013 #5

boggles the mind, doesn't it! take it a step further.... NRaleighLiberal Feb 2013 #9

correct. Viva_La_Revolution Feb 2013 #10

And you are following Quantum Mechanics? Sekhmets Daughter Feb 2013 #11

I find the energy transfer time in the sun (and all stars) to be even more interesting... DreamGypsy Feb 2013 #15

Very cool....*head explodes* clarice Feb 2013 #17

Yes it is wicked cool. Sekhmets Daughter Feb 2013 #19

Welcome to DU Sekhmets Daughter Feb 2013 #30

Thanks.....you ROCK !!! clarice Feb 2013 #33

Some very important knowledge about the cosmos is based on information ~13.5 billion years old. DreamGypsy Feb 2013 #13

Aw heck...just hop through a worm hole and travel a million light years in a sec and take a look... Sancho Feb 2013 #14

lol....and what's funny is... clarice Feb 2013 #18

Try figuring out quantum entanglement...so cool. clarice Feb 2013 #16

Considering a star, like our sun, has a lifespan of 8 billion years Confusious Feb 2013 #23

Yes, I used 1 million as a conversation starter. clarice Feb 2013 #25
