Next Generation Space Telescope

ok ok, wait- i stand corrected- dark ENERGY is theorized to make up 70% of the known universe- my bad...

[JBrd79]

Actually i read that dark matter is theorized to make up some 70% of our visible universe. that figure is straight from the NASA Website. I'm not saying it's correct but that's what the "experts" say. i wonder where the two of you got your figures from? :/

ok I was going to replace the hubble space telescope with a handmade one, but i was too busy. 30 yearsssss!!!! for a new telescope only 5 times more powerful than hubble???. I just hope this James Webb don't last 30 years in the space, because in 2040 the technology will be simply amazing with all that robots making coffee jaja.

u must be a nutsack if u think we are the only one in space soo many galaxies

[MAMOHT82]

1:32 cheap JWST rip off

[ASIANBOYZPRODUCTION]

it's like you can afford one!!

[bs2174]

Another sorry attempt to try to prove evolution. What a panty waist of taxdollers. The only thing good about "telescopes" is that we relly just get to see more and more of the glory of God.

[EasyWolf31]

Your a moron lol

[bs2174]

So is your comment.

[razorflown2]

I think it's awesome that our tax dollars are going to these projects. I think it's great that obama will tax the fuck out of everyone and use the money to fund science. Science has only been dominant for the last 100-300 years. You christians had 1000+ years, remember? The dark ages? The middle ages? You're a piece of shit. How fucking stupid can you be? Go fuck your goat some more you ignorant tard.

Do you kiss your mother with that mouth?

[gmpep3]

I was on pins and needles when the Hubble was created and launched. I hope I'm around for the James Webb. What a very special time in human history!

[joshig1983]

A wikipedia article says the launch will be no earlier than June 2013. I guess there have been some delays.

[Mattnesss]

oh sorry! I really should read the video descriptions more carefully

[Mattnesss]

dark matter doesn't make up 90% of the mass of the universe... it only makes up 22%. Our visible matter makes up around 4%. DARK ENERGY (!) is what makes up the most mass (around 74%).

I like this video, but that's a bad mistake to make :P

[stevebd1]

The video is from 2002 when the term dark matter pretty much covered the unseen matter/energy that made up most of our universe and dark energy was speculated. Its only with the observation of type 1a supernovae at very high red shifts within the last few years that the existence of a dark energy was confirmed and the term became an accepted phrase in present day cosmology.

[TitaniumDragon]

I rather suspect dark matter/energy is an error in our current physics rather than a huge portion of the universe.

[Mattnesss]

The thing is that everything we observe fits the idea of dark matter and energy. In fact we directly observed the gravitational effect dark matter has (there's a great picture of the ring of dark matter, it's easy to find) and you couldn't explain the rotation of galaxies without there being dark matter.

We don't really know much about dark energy yet, just that some "energy" must exist. Thus the name dark energy, we don't know what it is, just that it is.

[TitaniumDragon]

That "ring of dark matter" is what is more commonly known as a "black hole", but black holes DO NOT make up much "dark matter". We COULD explain the rotation of galaxies without dark matter -with different physics-. That's apparently what you don't comprehend; when everything isn't matching up nearly correctly, it means that our physics are wrong. People just haven't come up with a correct theory yet, probably because it is weirder than relativity.

[Mattnesss]

I'm not talking about black holes... Astronomers mapped out the distribution of dark matter by observing it's gravitational effect on the light of objects in the background. The dark matter distribution is ring shaped in this picture. If you had just googled "ring of dark matter" you'd know what I'm talking about...

[TitaniumDragon]

Oh, THAT. I know what you're talking about now. The problem with saying "gravity blah blah blah" is that the theory of relativity is probably WRONG; when you can't explain 96% of the universe with your theory, then you've got a major problem, and it isn't that 96% of the universe isn't there, its that your theory breaks down. Basically the map was made from the theory of relativity, so if the theory is wrong, then the map is worthless, which is probable.

[AbelMagwitch73]

What is your point? If you think that relativity is wrong, what is right? Where does 96% come from?
