Holy fuck that looks cool :v:
[QUOTE=Warriorx4;27684158]Is Webb gonna replace Hubble? :ohdear:[/QUOTE]
Hope not, Hubble rolls off the tongue, "The Webb Telescope" is just gonna sound weird.

[QUOTE=Contag;27684851]What we see of the sun is eight minutes old. Looking eight minutes back in time. (!)
If the sun were to explode right now, it would take 8 minutes for us to be aware of it.[/QUOTE]
If it was to explode, wouldn't we be aware of it pretty much straight away?
With all the burning up of the atmosphere, melting flesh, and all that fun shit.
Granted, we might be able to look up and see the sun wearing its shades and smile, and giving us the thumbs up, but are we gonna give a shit?
But the first part is right, The sun we see is as it was ~8 minutes ago

No, we wouldn't be aware of it straight away. The fastest thing we know of is light, and it'll still take eight minutes for us to be bombarded with deadly radiation as radiation is still light. The sun is also just a big ball of gas and gas wouldn't immediately effect us.

My point though, was that the closer this big ball of gas gets to blowing our shit up, the hotter it's gonna get for us, until our atmosphere burns up and we all melt, evidenced by the fact that we're in the suns sweet spot for habitable life, while mercury and venus are way too fucking hot to live on (The whole Astronomical Unit thing).
That would happen before 8 minutes (but because it's closer, would we see it sooner?)

Yeah, there'd be signs beforehand if it were to explode, and those signs would probably kill us.
I'd wager that if it took more than a minute less for light to travel here, we'd be dead anyway.
[QUOTE=Gmod_Fan77;27684213]How can they look back in time with a telescope?
Damn it, space is fucking confusing.[/QUOTE]
you can't because space is a lie by Satan meant to make you hate the Lord
You guys seem to be missing the very important factor that the sun can't randomly explode right now. Before it goes supernova, our planet will be so close to the sun that Earth would simply turn into another Mercury.

[QUOTE=DELL;27685032]Even so that's not changing the fact that present time is present time because we can't move fast enough to notice that small of a change in time.[/QUOTE]
It has nothing to do with how fast we're moving relative to the photons that are hitting our retinas. It has more to do with the fact that there is currently no existing wave in the known universe capable of traveling to something instantaneously.
Light is fast, but it still takes time to travel. Why do you think there are light years?
We [I]are[/I] living in the present, but virtually everything we see is how it was a fraction of a nanosecond ago. Unless you're looking at the night sky. In that case you're talking about a scale of years.
