As each decade passes, the probability that somebody will possess the courage to suggest that all of this investment was a mistake will predictably approach zero.
Where have ya been living? Ya need to get out more, people suggest this all the time.
Actually, no. What's implied is the presence of an unseen, distributed source of gravity.
This gravitational lensing result is certainly interesting, but CDM theory has a long way to go before we'll conclude that it's correct.
But until we pin down the nature of that matter, it's an *assumption* that any form of matter is responsible for these observed gravitational phenomena. ... it's still an assumption.
... and to the horror of scientists it isn't understood via current models. Now THAT is SCIENCE!!!! ...
When DM causes gravity, then one can assume, that DM is also attracted by gravity. Or not?
If yes, the DM should also form bodies and fall on bodies made from ordinary matter.
There's nothing they like more than a mystery and the opportunity to discover something new
They say that a quark-gluon plasma can only exist in extremely high T. But what mechanisms could lead to a cooling.

Jun 13, 2013No offense intended to the researchers, who I trust are extremely talented, but one wonders if dark matter researchers will eventually regret not widening the scope of their investigation to also include questioning accepted hypotheses. A person can be forgiven for suspecting that we are at an impasse here, and that the situation will simply not change for the better.
Re: "few scientists seriously doubt that it exists ..."
Perhaps that's actually the problem. If the discipline basically weeds out approaches which question foundational hypotheses, then wouldn't this be an extremely risky strategy in the event that a wrong turn was taken? Many lines of investigation have been tossed out along the way. As each decade passes, the probability that somebody will possess the courage to suggest that all of this investment was a mistake will predictably approach zero.
