Re: The universe is expanding faster than expected
#2One thing I've always admired as a Layman about astronomy, is all the eloquent deductions they've been able to make that adds another framework of ways to discover new information, particularly the discovery of Cepheids.
Obviously the engineering side is also as impressive, being able to look at objects light years away and using the paltry several hundred million miles our Earth orbit takes us around the sun as a means of information discovery.

Don't worry too much about it. In the end, everything will be nearly 0k.

I appreciate your optimism. I tend to be optimistic about the future myself. But there is no law of the universe that everything will work out ok. Only if we make the right decisions as a species and we don't get unlucky.
I'm quite apprehensive that the great filter lies ahead - that technology accelerates too rapidly compared to our wisdom and we end up nearly destroying ourselves. We're getting the ability to program life itself and to likely to democratize the ability to harness the forces inside the atom. Neither of which we're ready for as a species.

"The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every ‘superstar,’ every ‘supreme leader,’ every saint and sinner in the history of our species lived there-on a mote of dust suspended in a sunbeam" - Carl Sagan
And that pale blue dot means nothing in a cosmic scale. Stop worrying and enjoy the incredible fortune of being alive.

I think it was a joke about zero Kelvin.

I believe the OP said 0K, not OK.
There may not be a universal law which says everything will be OK, but there is one which says everything will be 0K in the end.

#10Actual title:
Astronomers Get Their Wish, and a Cosmic Crisis Gets Worse
There seems to have been a reframing of the "crisis" at some point, with "discrepancy in measurements" becoming "expanding faster than expected" which latter seems to imply the Reiss camp has the expansion rate correct compared to the earlier mystery as to which might be true and why they might be different but both sides on an equal footing otherwise.
Reader (me) misunderstanding, actual change in scientific perception or PR work by somebody?
