just can't see it!

It's the black blob with shifty eyes and funny legs.
The dark energy batteries certainly look good too - could come in handy.

Nicely refutes your argument about stubborn blind people ;) We are all blind to most of the universe, but that doesn't stop us from accepting that there must be something there.
Why have those people got bug eyes anyway; does that come from looking through telescopes too much ?

Not if one is really stubborn. Anyone can ask a million questions about Dark Matter and Dark energy which no one will be able to answer. It is easy for people to argue against such exotic stuff. But anyone who is reasonable would see the point of such assumptions.
It is similar with things like emergent properties needing Intelligence, NDE's indicating an after-life etc. People can be reasonable or they can be stubborn like the blind man.

There is hard evidence, albeit indirect, for something that we provisionally label 'dark matter'. There is no such equivalent for 'after-life'. That is just fanciful interpretation of personal anecdotes. Such personal testimony hardly counts as hard evidence; to do so would be regressive, we might as well go back to medieval blood letting to cure diseases. We have learned the hard way what counts as good, telling evidence, we should not be in the business of abandoning good standards.

just pack it in eh!

No, it isn't. Actual objective evidence is not similar to baseless speculation or wishful thinking based on anecdotes.

To a stubborn blind man...experience of light is anecdotal!

not if its ultra violet or infra red

No it's not. Light can be measured using a light meter. Nothing anecdotal about light meters.

You think a reading on some meter would convince a stubborn blind man that Light exists all around him?! LOL!
How would he know what the meter is measuring? And whether it really is measuring this mysterious thingy called Light? And whether someone hasn't rigged the meter in line with their belief in this Light? How would he still know what Light is?
He would still have to take the word of the non blind.

blind people are not so stupidly stubborn. All the people I know with sight loss have to find ways to be more resourceful and practical for a start.

I think you mistake stubborness for stupidity.
I can't hear infrasound but I am not so stupid as to deny it because it can be measured with instrumentation.
I can't see infrared but I am not so stupid as to deny it because it can be measured with instrumentation.
Maybe you need to distinguish between stubbornness and stupidity and you need to learn the difference between anecdotal evidence and hard evidence.

Remember the two boxes I talked about?!
When something is within your belief system you will accept anything, however far fetched....Dark Matter, Dark Energy, Worm holes, Singularity, String vibrating in 11 dimensions, Seven dimensions wrapped around a String, Parallel Universes, Simulated Universes......whatever.
But when something falls outside your belief system, you will not accept anything at all....however obvious and simple that may be. Emergent Properties and Complexity are obvious indications of a direction and Intelligence. NDE's monitored by professional medical experts and psychologists, are obvious indications of an after-life.
You will dump things in the two boxes in your brain and accept everything in one and accept nothing in the other. That is stubborn or stupid...you decide.

Science doesn't do beliefs.
Science is based on evidence, observation and reason. If there is solid repeatable evidence, then we will want to investigate and learn what we can. You are still mistaking rigour and discipline for stubbornness. In a post-truth world seemingly awash with misinformation, conspiracy theories and fake news we need discipline more than ever to help us focus on what is actually true amongst all the noise. To abandon that discipline would be a backwards step.

Sounds like you're describing yourself when you talk about these two boxes, Sriram. ;) :)

Here's your first mistake: science isn't a belief system.
Dark matter and dark energy are assumed to exist because the Universe behaves in ways that strongly suggest they do. Black holes have been observed. Worm holes are a theoretical consequence of General Relativity. They may or may not exist but nobody claims they definitely do. The eleven dimensions of string theory and parallel universes are only speculation and seen as such. Singularities are an embarrassment to GR and therefore it is thought that GR is incomplete or subtly wrong.
So, no, scientists don't accept anything however far fetched.

I read Sriram's post and before immediately responding with 'rubbish', I read the next post, went to reply and got the 'This page can't be displayed' notice. that lasted right until now actually.
Mind you, that doesn't alter the fact that I still think it was rubbish,! :)

Thinking that only material things can exist, everything requires 'hard evidence' in the form of measurable parameters, science is the only way to understand reality, anecdotal experiences cannot be evidence for real phenomena, changes in properties of organisms can occur through random variations only.....all these are beliefs.

The ToE is not a belief, it is a theory drawn from observation and evidence and as such is subject to constant update, unlike beliefs.
Who says only material things exist ? Energy is not matter, quantum states are not matter, spacetime is not matter.
Anecdotal evidence is poor quality, typically, so we value forms of evidence that are more robust. Nothing wrong about that. If we open the door to anecdotal testimony, all manner of mumbo jumbo will get sucked in. It is a good thing that we make effort to keep our knowledge base clean.
-

...everything requires 'hard evidence' in the form of measurable parameters...
Not sure what "measurable parameters" means in the context. However, if we don't have consistent, objective evidence for something, how else do we distinguish a real phenomenon from guessing or mistake or misinterpretation or wishful thinking or...?
...science is the only way to understand reality...
Well, it appears to be the best why to understand matters of objective (intersubjective) fact. If you have something as good or better at that, then feel free to share.
...anecdotal experiences cannot be evidence for real phenomena...
Well, of course they can be. However, anecdotal evidence alone is not a basis for believing something - if it were, we'd have to believe many mutually contradictory things - which would be very confusing.
...changes in properties of organisms can occur through random variations only...
You'd do yourself a big favour if you actually bothered to study and understand the subjects you address. You seem to have a completely fixed - and largely inaccurate - view of both science in general and of specific scientific theories, hypotheses and speculations. Hence, you seem completely unable to grasp (for example) the actual theory of evolution by natural selection because it is nothing like the idea that is fixed in your mind. You cannot see that dark matter is in a totally different category to singularities which are in a different category to parallel universes, no matter how many times the distinctions are pointed out.

Ah, another of your good posts, Skos.
I also agree with Walter's, 'I'm glad I'm not you.'
-
this has been done so many times now , there's no getting through to him , he simply repeats himself but offers no method or evidence or the slightest glimmer of any way of evaluating what is clearly wishful thinking.
Sriram, saying it over and over again does not make it more true or real.

I am not talking about the Theory of Everything that scientists are trying to come up with. Not likely to happen anytime soon. And it certainly cannot be a ToE if it doesn't take into account Consciousness.... or even if it attempts to explain matters of Consciousness, spirituality etc. through some Quantum Mechanical process.
I am talking about the philosophical position some people adopt that only material measurable phenomena can exist, consistent anecdotal experiences cannot be evidence, Science is the only way to understand reality, what we cannot sense directly cannot exist...and so on.
These are clearly wrong premises and a wrong philosophical stand. There are some articles in the Freethought section that show how the attitude of scientists is now changing. But some people seem to be stuck in the 'Hard' science of the 19th and early 20th century. ::)

We cannot directly sense the vast majority of things and it is because of science, not in spite of science, that we know such things. With our inbuilt senses we cannot hear infrasound or ultrasound, we cannot see dark matter, we cannot see subatomic particles, we cannot sense magnetic fields. What we can sense directly is a tiny fraction of what there is and we have science to thank for revealing all these things.

Yes...these are all through sense extensions.....but they all belong to the same class of phenomena.
But tell me...why do you accept the idea of Parallel universes...but not the idea of spiritual worlds? What is the difference? This is what I mean by dumping ideas into two boxes.
-

Like what? The "Evolvability" one that you didn't understand or the "Atheism dying?!" one in which you made an unevidenced assertion science was changing and ignored my request for clarification?
But tell me...why do you accept the idea of Parallel universes...but not the idea of spiritual worlds? What is the difference?
As far as I know there isn't even a widely accepted definition of the term "spiritual worlds" - what does it even mean? If you have clear hypothesis or conjecture and can gave reasons why it should be taken seriously, it might be something that could be evaluated. Wittering on about near death experiences really isn't anywhere near enough.
There is no idea (singular) of parallel universes. The term is used to refer to several different ideas with various reasons as to why they might exist. The ideas range from making fairly straightforward assumptions about known and tested theories, to speculations that are no better than science fiction.
So there aren't actually two ideas here to accept or reject.

I'm not sure we do accept 'parallel universes'. If you refer the the Many Worlds hypothesis, that is a conjectural explanation for observations from quantum mechanics; there are other rival ideas for things that we currently cannot explain through classical physics, but the observations are real and repeatable so there is some real phenomenon there requiring explanation, and we are having to dig deeper past our everyday intuitions about how reality is in order to glimpse what underlying reality these observations are telling us about. There is no comparable hard evidence for 'spiritual worlds', just cultural beliefs and personal anecdote.
