I think everyone would agree with that.
The thing is, everything keeps pointing to "this one thing." And, "this one thing" does not contradict what we believe is already firmly established understanding. Further - When we take what we know and apply it to what has been proposed, it all "works."
Does that mean it is "true." Well, if you can't measure it directly, yet, but its effects are predictable as you have modeled what it may be, then it doesn't matter if it's a bit of dark matter or a unicorn - It works.
I prefer to think it is as it has been thought of, with possible exceptions if we find something extraordinary. But, it all seems to "work" with what we already depend upon and what ideas we have relied upon to get us this far. And, if that continues I am happy to visualize it however science says we should until something else comes up.
"Dark energy," though... What's the next "Dark" gonna be? I "get it", but are we starting to move into the limits of our ability to comprehend? What next tool is going to help answer these questions and what truths may it reveal that cause us a rethink?
