Re: Explanation for Dark Energy
continuing: The stars' speeds may have been even slowing a bit near the edges of the galaxy. A very flat rate change, though. As for the seeing in infrared business again. Very cold objects are rather black in the infrared.* Likely the material is of a type that has to be very cold in order to remai...

Re: Explanation for Dark Energy
From what I gather the source of gravity would have to be in the outer part of the obsrvable galaxy, though some perhaps beyond, The speed of the stars noted though suggest that the center of mass apparent to the star must me closer to the center of the galaxy than it is, though not nearly as far wa...

Re: Explanation for Dark Energy
If it is much cooler and especially behind a warmer material it would not be notable. Temperature by itself in not a very valid indicator of the presence of a comet like mass of very cold material. The voyager space crafts flew out of our solar system and may be near the edge of the solar wind influ...

Re: Explanation for Dark Energy
Another factor that may fool calculations up is the possiblity that a black-hole may not be able to 'generate' all the gravity its mass might allow. This may be due to the fact that gravity must ride on the back of other flows of energy (or of course matter) and that the event horizon will also prev...

Re: Explanation for Dark Energy
Dark matter and dark energy... Both being undefined, I digressed. Has anyone ever studied a theory for this universes creation via a relativistic humongous (weight wise) black-hole colliding in an old, nearly energyless universe, possibly with smaller black-holes scattered in its midst? If you note ...

Re: Explanation for Dark Energy
noble gases cause gravitation in the outer parts of the galaxy without being observed? The whole problem with with the study is that if something is cold enough it does not radiate in any form that can be observed. Admitted, since light passes through space it can also indicate the presents of a ga...

Re: Explanation for Dark Energy
Hi again, No, I got the idea. The standard theory holds that Dark Energy is the main thing the universe is made of(about 70%), next comes Dark Matter(about 20%), normal 'visible' matter the least. There are those saying that is there was just more gravity (any source) in the extremities of the galax...

Re: Explanation for Dark Energy
Amir H Taheri suggested one should look for anti-matter by relating it to anti-gravity. Personally, I have a hard time with a ubiqutious dark energy, or matter, that is not specifically detailed by a theory giving it a 'means' for it to exist also. I hear there is in some theories a particle they ar...
