Skip to comments.Update on the universe: Top scientists gather in Dallas to dissect space, matter, time
Posted on 12/07/2013 8:34:53 PM PST by gooblah
An idea hatched around a Dallas swimming pool 50 years ago has blossomed into one of the worlds most prestigious scientific conferences.
Starting Sunday, more than 450 experts on gravity, black holes and the newly discovered Higgs boson the subject of this years Nobel Prize in physics will gather at the Fairmont Hotel in downtown Dallas to discuss the newest findings and most pressing mysteries in their fields

I hope they focus on what exactly gravity is. Resolving the Grand Unified Theory problem would be very cool!
“Resolving the Grand Unified Theory problem would be very cool!”
Or even more groundbreaking... what causes that double-post thing on FR.
I would be satisfied knowing why my snowblower won’t start unless it’s warm.
In Dallas? Lets hope they are not talking about no black holes.
...dissect matter, space, time...
Hey! Wait there pal, I’m using that stuff...
Sounds like a neat conference. They have opened it to the public which is nice. I wonder if they will put it up on Youtube.
The universe on speed
One of the most pressing questions for astronomers is why the universe appears to be expanding faster and faster. Researchers made the discovery in 1998 and won the Nobel Prize for their work in 2011. That was an amazing, counterintuitive discovery, says Kolb. Whether people admit it or not, every cosmologist expected the expansion to slow down because gravity should act to pull everything back together.
Scientists believe an invisible force called dark energy is driving the quickening expansion. While much of space may look empty, Einstein predicted that it had mass. If empty space has a mass, it also has a pressure that pushes space apart, says Kolb, who will deliver a public lecture on the unseen universe at UTD on Wednesday evening. Scientists at the symposium will discuss how to design experiments to improve their understanding of dark energy.
This will likely be a re-creation of the Salk Institute conferences.
Sam Harris: TSN Beyond Belief 1/2
Just one example.
There is so much more:
Richard Dawkins, Lawrence Krauss, deGrasse Tyson and more intellectuals bashing religion.
Mark my words:
This event will be a platform for the promotion of “POP Science” and an unchallenged attack on religion.
Mark my words.
If the Deadites gain control of the Necronomicron at this conference, well, a terrible evil shall befall humankind and more stuff, harrumph.
Did you say the words?
Klaatu... Verata... Necktie.
The result will be 28 lbs of belly button fuzz.
Conclusion?.........islam is a true religion, all roads lead to islam no? Kinda like the kevin bacon game
I'd like to hear what their conversations are like in the bar during happy hour after a few drinks....LOL!
I knew Sheldon was on to something...
That was funny!
It's Bush's fault.
I attended one of these in the mid nineties at the Smithsonian in DC. It was a good thing that I read all of the papers and background info before going. Not really something a low-information voter could just walk into.
That is VERY cool! The kid has a lot of talent.
(I don’t understand it — but after watching, my vast ignorance is less vast than it was before)
Gravity is the equivalent of infinite, accelerating universal expansion. I wish the eggheads would see that.
Look at the units for Newton’s gravitational constant, G:
Centimeters cubed divided by grams seconds squared.
Put it another way. It is
(Centimeters cubed per gram) per second squared.
Since it is something per second squared, it is an acceleration. We know G to be a small but positive number, that something is going to get bigger and bigger.
What is the “something”? Centimeters cubed per gram SB familiar, it is the inverse of the density.
So since the inverse of the density is getting bigger and bigger over time, we correctly conclude the density is getting smaller and smaller.
Thus, the average density of the universe is getting smaller and smaller, the mass is getting spread out in the vacuum, the fact that mass tends to gather together is a consequence of gravity, not the definition of gravity.
Thee big bang didn’t “happen”, it is still “happening”.
All of this is not just my opinion, I’ve read several abstracts that say much the same thing.
I just watched it again and I have a dumb question: If the math leads to ten dimensions, why “compactify” down to four?
Check out loop quantum gravity.
Usually for either convenience or simplification. Like when I heard light has a miniscule mass...I had to re look Einstein’s Field Equations for the base assumptions. That is usually where the weird stuff happens, like spooky interactions at a distance. We have more to fill out for a full understanding.
I loved the normalization issue, he really hit it home.
Did you see this? http://freerepublic.com/focus/f-chat/3098695/posts
It sounded interesting to me, but (sadly) way over my head.
Over mine too...but he was not doing pure thought experiments which I believe are severely overused...biology especially...
He caught an entangled pair...
Gravity is not just out of our grasps, it may be within our lifetimes, we’re just a little behind our feline friends who have been testing gravity for millenia.
