Can someone help me with this question.
I've noticed that NGC 1300,2442,1365 and our Milky Way Galaxy all have a Bar of stars at the center. Does this have anything in common with the modal of the gravity wave center?
What forms the bar?

In all the years that bars have been observed, I don't think a sustained explanation has been found. The difficulty is what is visible vs what is not. Models based purely on luminous matter distribution run into difficulties, as the observed tangential velocities of stars as a function of radial distance from galactic centre doesn't fall off fast enough. This eventually lead to the concept of 'dark matter' which, by definition, allegedly contributes to such dynamics but is unseen. ( Don't confuse this with 'dark energy' which refers to a quite unrelated idea on a vaster cosmological scale ) Until a full accounting is achieved of all gravitationally active elements then explanations of all structural patterns remain moot.
Cheers, Mike


In all the years that bars.........structural patterns remain moot.

I've just looked a few things up.
If we judge matters upon visible stuff alone, then the overall/average tangential velocities of stars in a galaxy should fall off like the inverse square root of the radius from galactic centre. This is very similiar to our own solar system, and is a 'Keplerian' distribution if you like.
However for very many galaxies looked at to date the measured velocities are pretty constant ( ie. not subsiding ) with radius, and out to a considerable distance too. It is posed therefore that a globular distribution of invisible material ( aka dark matter ), also centred on the galactic centre as visibly defined, would explain things. If so one can deduce some properties of said dark matter.
Now some observations have shown that no edge has yet to be defined for the extension of such dark matter into intergalactic space. I think the motions of smaller satellite galaxies similiar to our Magellenic clouds in the Milky Way were considered here. This raises the serious possibility of vast extensions of dark matter into what are otherwise deemed 'voids', many galactic radii away.
Studies of gravitational lensing of light from some galaxy clusters have deduced the presence of considerable non-luminous mass that contributes to the bending of the light. ( The entire material produces multiple images of some other galaxy or object well behind the cluster as viewed by us. By analysing the images carefully one can uniquely determine the mass distribution that produced it ).

Strings calm the chaos. And as a single string dances through space, it sweeps
out a tube. The tube can act as a bubble that surrounds the tear. A protective
shield with profound implications. Strings make it possible for space to rip.


Well, the 'tube' is what happens when the 'string' vibrates back and forth very rapidly. Picture a piece of a rubber band stretched between two fixed posts, or maybe better, picture a guitar: when you pluck a string, if you look closely, you'll see that it not only vibrates back and forth, but it is also vibrating up and down at the same time. So rather than looking like a flat ribbon as it vibrates, it looks more like a tube, even though you plucked it in only one direction. Brian Greene was explaining how the 'tube' might allow a surface with one shape (say a plate or saucer), to morph into a different surface (say a doughnut, which has a hole through it even though the surface is still what mathematicians call 'continuous'). How might a hole form in the surface of the shape without it tearing? A tear in the surface, for various reasons, doesn't fit well with either maths or physics. So I think Brian Greene was making a point that the strings of 'String Theory' might keep the fabric patched while it morphs around a tear, specifically regarding the situation where there's lots of mass in a very small volume of 3D space, like near a black hole, I think the rationale being that a wormhole is possible, in turn making possible the connection of points in space that are otherwise far apart in distance and/or time.

So what causes it and how far does it stretch? The strings vibrate in various patterns, to account for the various particles in the Standard Model, and according to the show, if you enlarged an atom to the size of the solar system, then these strings would be about the size of a tree, an eleven dimensional tree, so try to picture not an empty solar system, but millions forests stacked on top of each other, forest as far as the eye can see, for all the trees. :)
I hope I interpreted the show correctly

Honored Crunchers,
Instead of a shotgun, how about a BB gun (single shot partical beam) where the contact points were guaranteed from 3,5, or 6 different directions?
Is it possible?



Two reasons why this won't work:

It would be impractical to build a machine of sufficent power to make this worthwhile.

Secondly, and more importantly, the extremely small size of the particles involved would make it impossible to guarantee a result. Think of the differences in scale between the electromagnets and other hardware required to build the machine, and the size of the particles. You'd be talking of tolerances in billionths of 1%, or smaller.

Even in the existing particle beam accelerators most particles just fly straight through the collision points. Collisions are a very rare event, and only happen in reasonable numbers because there are many many many opportunities.

I was just wondering if anyone knew of any future
plans to build a supercollider who's atoms met at
one point from 3,5,or 6 differant directions?


Don't think so.Reason being the chances of a three way collision are too small to make it worthwhile.

Say you had a three-way collider. Most of the collisions would still be two out of three, and by most I mean maybe one in a few billion would be a three way.

Think of firing two shotguns at each other, a few of the pellets will hit each other, most will miss altogether. [this is a thought experiment, don't try this at home!] Think of firing three shotguns into a central place. To be useful a three way collision has to be reasonably simultaneous. Pellet 1 & 2 collide and pellet 3 must arrive before 1 & 2 react. Crump then crump is no good, it has to be crumm-Crump for the energy to build anything useful.

The particles in a particle beam are much further apart (in relation to their size) then the pellets in a shotgun blast, and the move faster.

How long, moving at 99% of the speed of light, does it take to travel past an electron - that is about the maximum time you'd need between the two collisions.

And the extra energy would only be another 50% up from a two-way. It is therefore more reliable, cheaper, and easier to design to increase the power of the two beams by 50% each than to add a thrid beam line.

I remember when 3GeV was cutting edge (I was at CERN at the time). Since then machines have got a load more powerful, but each increase has kept to the one-on-one design. If it would help to have extra beam lines they'd have done it long before now. Instead they keep making the circles bigger.

No idea on the cost of something new like the Rubbio reactor.

Considering that we spend 6 cents per kilowatt hour on something as simple as bringing nuclear rods near heavy water and pumping the hot heavy water to a heat exchanger, the laws of economics may say have us going after solar, wind, and fuel cells powered by bio fuels before we start aiming beams at lumps of nuclear fuel.

How much does a synchrotron cost? Do we run them as a continuous light source currently, or do we use them like a flashbulb for a really bright light for a short lived experiment.

A synchrotron is made up of supermagnets, cryogenic fluids, vacuum chambers, shielding to protect people from gamma rays, http://www.lightsource.ca/education/whatis.php

Canada's light source cost 174 million dollars, and is used as a light source for scientific experiments. http://www.wd.gc.ca/innovation/cdnlightsource/default_e.asp so it's not intended to be the front end to a power plant.

Considering that people are concerned about gamma rays from the experimental sized equipment, you can be sure that an industrial sized objects would be of larger concern to the public. http://www.synchrotron.vic.gov.au/content.asp?document_id=276

Wikipedia has a brief description of this.

http://en.wikipedia.org/wiki/Rubbia_reactor

I'm guessing that nobody has built a commercial sized reactor due to the fact that you need to feed the reaction with complex equipment.

From the Wikipedia entry:
Disadvantages
* General technical difficulties
* Each reactor needs its own facility (synchrotron) to generate the neutron beam, which is very costly.
* No synchrotron of sufficient power has ever been built.




Sir,
What are the details of the General tech Difficulties and does the cost outway the lives saved if thiers a chain reaction?
