Re: I don't object to changing my mind, but can take more convincing than I really should. Dreaded Anomaly Send a noteboard - 14/06/2011 03:38:05 AM
Generating hypotheses by itself is not science; it's really not even amateur philosophy, just day dreaming. Anything you can't test is just speculation, not science; without the scientific method, what is science but speculation? More practically, how does pulling something out of our rear that MIGHT be true (but unverifiable) advance anything? If that qualifies as science angels and aliens are sound scientific hypotheses. When you speculate on speculation, yes, most of your hypotheses will be wrong: That's the problem.


If you put gas in your car and don't turn the key, the car doesn't go anywhere, so what's the point of gas?

Science needs multiple elements to succeed; different people make different contributions. We can't test ideas if we don't have any! This is not a hard concept, and I really don't understand why you are persistently bothered by it.

He's no longer claiming confidence alone, but certainty, emphatically and repeatedly. That it was a pre-existing certainty only underscores the reservations that creates in me. Remember, I'm no longer saying exotic dark matter isn't very probably valid, just that it's still too soon to treat it as the slam dunk Dr. Carroll does. It's clear he'd already come to that conclusion and is only citing supporting evidence as it becomes available; that he has the education and awareness to find it doesn't make it more credible.


Sean has worked in this field for virtually his entire adult life and has made significant contributions to physics and science outreach. He has a clear and broad understanding of astrophysics and the universe as humanity has observed it so far. You have an opinion on the issue based on an understanding of astrophysics which could charitably be called shaky and very little time spent looking at the evidence. You continue to resist revising your opinion to the appropriate level given the evidence. But yeah, it must be Sean (and most other astrophysicists) who is rationalizing. Give me a break.

It's called, "the scientific method", and involves hypotheses one can test, not simply throwing out an idea not fundamentally contradicted by current evidence and hoping someone some day finds a way to test it that ultimately validates it. That's a lot bigger and less certain area than pure science; let's say there's a God, and based on that hypothesis let's say He created man in His image: Having established those things we can say all SORTS of things on the basis of them. None of them would be science though.


We won't ever figure out how to test a hypothesis, or if we already have evidence relevant to it, if we don't explore the idea. Theoretical science looks for new ideas, as opposed to theology, which continues to look at old ideas that have already made numerous failed predictions and are no longer worthy of consideration. Yes, theoretical papers won't be right all the time, or maybe even a majority of the time; that's still very different from continuing to go in directions that are obviously, blatantly wrong.

I still think dark matter's just non-luminous matter without a convenient light source to reflect. Joel - 28/04/2011 10:34:21 PM 869 Views
We've just about ruled out the idea that dark matter is just non-luminous "ordinary" matter. Dreaded Anomaly - 28/04/2011 11:44:34 PM 808 Views

Might help if you clarified where your skepticism is at Isaac - 29/04/2011 02:32:07 AM 690 Views
Potentially either, or a combination of the two. Joel - 30/04/2011 02:36:50 PM 762 Views
It's hard to discuss without knowing your objections a bit more clearly Isaac - 30/04/2011 04:58:03 PM 671 Views
My primary objection is that alternatives to dark matter seem to have been ruled out prematurely. Joel - 02/05/2011 01:29:14 AM 803 Views
Well, they weren't, not really sure how else to put that Isaac - 10/05/2011 03:19:57 AM 861 Views
Alright then, objection withdrawn (cautious skepticism intact). Joel - 14/05/2011 05:34:17 AM 971 Views
