Sure it is. Observing an effect caused by an object is observing it.

When you look at a flower you are observing the selected frequency reflection and scattering by the surface of the flower. The plant itself is not emitting light. When someone slaps you you observe it through various pain signals sent to your brain. There are many ways that observations can be made. Your personal prejudices do not apply.

Of course it is. We are detecting the effects of the dark matter on the gravitational field. When we use light to detect something, we are using the effect of that thing on light. When we use electrical current to detect something, we are using the effect of that thing on electrical current. All are observations of the thing causing the effects.

No, it is not, and your analogy is flawed.

Observing a flower is a process of interpretation through our sensory apparatus.

Observing the "effect" of a flower, say, the honey assembled from its nectar is NOT observing the flower.

Wrong.

All "observation" ultimately occurs due to our senses.

This idea of "observing" dark matter, or anything, by exterior effects it has on its environment is to add another layer of cause and effect.

You observe the "effect" of a flower when you look at it with your eyes, and impulses travel to the brain.

So far, there is no "flower" to observe for dark matter. There is nothing to observe to produce the image in the brain. The best you have is an effect caused by something THAT HAS NOT BEEN OBSERVED.

Wrong. When we observe the flower, we do not see the flower itself, but rather the light reflected from the flower. In other words, we detect the effect the flower has on the ambient light.

In the case of dark matter, we use the effect that dark matter has on passing light. The lensing of the light allows the detection of the dark matter, just as the reflection of light allows the detection of a flower. Both are examples of observation.

I should also point out that the measured matter and energy densities were *way* too low to cause re-collapse. So the likelihood of eternal expansion was considered the most likely possibility.
Now, we know there is dark matter, which was not on the original tally of matter and which makes up quite a large contribution. We also know the cosmological constant is not zero, which means the range of possibilities is much larger. In particular, it seems that our universe is geometrically flat but will expand forever at an increasing rate.
I approve of terms such as "the range of possibilities is much larger" (I assume that means larger than the likelihood of eternal expansion? only faster and faster? of if not, what?) because the words are not making much of a claim to certainty. I also like the term "it seems that" even when you seem to think something is more likely. the lack of dogmatic assertions of certainty make me more comfortble with your scientific preferencess, which - as an agnostic about more than religion - I find much preferable to scientific assertions.

Proof to 100%, that there cannot possibly be any god at all-- what sort of god would permit such as these examples of insanity, to represent it?
how can you assume there could not be an awful creator god, capable of creating disgusting things? I certainly hope there isn't a mostly bad creator god - sort of like the Biblical one - but it is far more likely than an allgoodallpowerful one, which is the one version I do strongly believe to be impossible.

obviously I do not believe in any sort of God (unless god is defined as all that exists, which is a really unusual definition), but there are degrees of disapproval of various gods and or God.
My degree of disapproval of the "creation" - the world as I know it, at least - and of the Biblical version of a Creator. at least match. Both of them quite horrid.

You are so full of shit.

No, you are not observing dark matter.

You are observing the lensing effect of light.

You are postulating dark matter from something you observe. There is no image constructed in the brain associated with something identified as dark matter, as there is with observing a flower. We do not postulate a flower. We observe it.

You OBSERVE the lensing effect of light. You DO NOT OBSERVE dark matter.

Nobody has ever observed dark matter, and nobody knows what it looks like, even if it exists.

It could be medium-toned matter.

Who the hell knows? Nobody.

Detecting is not observing.

You detect there is "something" causing an "effect" on light.

When you find it, we will all observe it.

So far, nobody has observed it.

I fully allow that you are so detached from reality that you might think you have observed it, because you read about it and have seen calculations involving it.

That is sad, but you are still wrong.

A blind man can "detect" a splinter in his ass.

He can't observe it.

It could be grey matter, but not in the case of creationists, who either always lacked gray matter or had it atrophy into non-existence from lack of use.

the bad thing about stars is that they can explode - presumably even if they have planets with some sort of life on them - or expand (which is destined to eventually fry us on earth if we do not do it first with global warming due to all the fossil fuel profiteering and political lies protecting it). Only the nice lady bugs are nice, not the ones that look like them only more orange, and which bite.

When light reflects from a flower, the rays are refracted by the cornea and focused on the retina, and an electrical impulse is carried via the optic nerve to the brain, where an image is conceived of as a "flower".

You are trying to tell me that happens with dark matter?

Describe the image your brain recognizes as "dark matter".

Do you believe absolutely anything somebody with a telescope tells you?

No, I am not saying this happens with dark matter. I am saying that isn't the only way to observe something. Observation is done by measuring the effects something has on something else. We have observed dark matter through its effects on light.

That's fascinating, Abused.

But I'm not a creationist.
