Mankind 'shortening the universe's life'

advertisement

Ya know you can't even look up at the sky at night without doing something to destroy the universe. The power that humanity commands is just astonishing!! (This of course assumes that there are no other intelligent life forms out there doing the same). What this means is that we don't know as much as we think we know about physics.

"The intriguing question is this," Prof Krauss told the Telegraph. "If we attempt to apply quantum mechanics to the universe as a whole, and if our present state is unstable, then what sets the clock that governs decay? Once we determine our current state by observations, have we reset the clock? If so, as incredible as it may seem, our detection of dark energy may have reduced the life expectancy of our universe."

Prof Krauss says that the measurement of the light from supernovae in 1998, which provided evidence of dark energy, may have reset the decay of the void to zero - back to a point when the likelihood of its surviving was falling rapidly. "In short, we may have snatched away the possibility of long-term survival for our universe and made it more likely it will decay," says Prof Krauss. Not all agree, since his interpretation hinges on one of the issues at the heart of quantum theory - do you need people to do the observing?

Who's leading the conversation?
This visualization below allows you to see the impact that each user has on the current conversation. The top row contains the group of users who have had the most impact, the 2nd row the group of users who have had the 2nd most impact (et cetera). Users with similar impact are grouped together, and the average score of the group is shown to the left of the group. The author of the article is also shown on the left, in their corresponding group. Each user's score is based on the number of comments the user has made plus the number of votes their comments have received. The scores are calculated relative one another, so while their absolute value is not particularly important, their relative difference does indicate a larger difference in impact on the conversation.

I think that once we discover a testable and observable theory of Quantum Gravity, much of the strange behavior we see in Quantum physics today will smoothly translate into the observations made by Cosmologists and Quantum effects we see now will be put in the proper context so that such applications to the cosmological state of the universe will not produce such strange thought experiments.

I do think that "strange" to use your word is an apt description.

Happy T Day
