According to Einstein's general theory of relativity, gravity can be thought of as the curvature of space and time. However, here the scientists point out that this geometry of space and time responsible for gravity gets deformed at the Planck scale. They have used the new theory of gravity's rainbow to account for this modification of the geometry of space and time near the Planck scale, where the mini black holes are predicted to exist.
Using gravity's rainbow, the scientists found that a little bit more energy is required to produce mini black holes at the LHC than previously thought. So far, the LHC has searched for mini black holes at energy levels below 5.3 TeV. According to gravity's rainbow, this energy is too low. Instead, the model predicts that black holes may form at energy levels of at least 9.5 TeV in six dimensions and 11.9 TeV in 10 dimensions. Since the LHC is designed to reach 14 TeV in future runs, these predicted energy requirements for black hole production should be accessible.
If mini black holes are detected at the LHC, then it would arguably support several ideas: parallel universes, extra dimensions, string theory, and gravity's rainbow—with these last two having implications for a theory of quantum gravity. Most obviously, a positive result would support the existence of mini black holes themselves.
"If mini black holes are detected at the LHC at the predicted energies, not only will it prove the existence of extra dimensions and by extension parallel universes, but it will also solve the famous information paradox in black holes," Ali said. Solving the paradox is possible because, in the gravity's rainbow model, mini black holes have a minimum radius below which they cannot shrink.
However, if black holes are not detected, the scientists will need to reexamine their understanding of these ideas.
"If black holes are not detected at the predicted energy levels, this would mean one of three possibilities," Khalil explained. "One, extra dimensions do not exist. Two, they exist, but they are smaller than expected. Or three, the parameters of gravity's rainbow need to be modified."
Fascinating stuff.
So lets make the single most violent and destructive thing in the universe, IN A LAB ON EARTH , just because we can. OH!! and the bad news is that it has a 99.99999999999% chance of destroying everything within 10 light years. Just sucking right down! Remember that the safety of this experiment is promised by the same people that believe Global Warming is "settled" Still think it's "cool"? ---Ray
ReplyDeleteI ain't no scientist and have little formal education, BUT - - - ,
ReplyDeleteThanks to the Berkeley Open Infrastructure for Network Computing (i.e., "BOINC") coordinated by the University of California at Berkeley, I (and YOU?) can volunteer my personal home computer as part of an international network of other volunteer home computers in researching raw data for selected scientific projects, including the European Organization for Nuclear Research (i.e., "CERN") Large Hadron Collider in Switzerland.
My pet project, the one that got me started originally, is the Search for Extra Terrestrial Intelligence (i.e., "S.E.T.I.").
This morning, Wednesday 25 March 2015, I received an e-mail notifying me that I had been selected as the USER OF THE DAY for the Rosetta@Home research project, operated from Baker Laboratory at the University of Washington in Seattle, which attempts to discover proteins that can cure human diseases.
These, and numerous other scientific research programs run in the background of your computer, allowing you full use of all of your other normal computing activities.

Since TODAY is the Twenty-Fifth, I want to wish everyone a "MERRY CHRISTMAS" ! ! !
Congrats on all counts!
DeleteAs for my interest in S.E.T.I., it ain't all that illogical science fiction, as in 1977, at the Big Ear Radio Observatory at the University of Ohio, an intelligent radio signal, now known as the "WOW!" signal (Google it), lasting about a minute and a half, and believed to have originated in the area of Constellation Sagittarius, WAS DETECTED AND RECORDED.
ReplyDeleteBut, there's been nothing since then.
I personally believe, based largely on my Christian faith (I'm a "Mormon" convert) that God created MANY worlds just like our own, populated with human beings just like us, as they, just as we, are created in the image of the Father of us all.
So, it's only natural that someday, there may happen some deliberate or accidental intelligent communication signal detected and recorded once again.
Science is a purely human activity.All humans are prone to error. Science is not always error-free:In 2011 one tracking agency recorded over 400 annual retractions of peer-reviewed published scientific papers that later failed closer scrutiny. A retraction is the most severe censuring action a published scientist can experience. As recently as the early 2000’s the number was just 30 or so. (Van Noorden, R. 2011 Science Publishing: The trouble with retractions. Nature. 478 (7367): 26-28.).
ReplyDeleteError, and the process for discovering and correcting the error, is the core of the scientific method. I always laugh at folks who holler that the "science is settled," because that is the polar opposite of what science is.
