Clue to move in time!

This is by NASA,JPL and california institute of technology.The green greed shows space time and purple grid shows dark energy.
I think that  space time grid is bend due to gravity and thus there is bending of time here.But there is no effect on purple grid which shows that there is no bending of time in dark energy grid.Is here any clue of being moving in time due to property of dark energy.

Structure of dark matter


This is dark matter structure and relation with known particals such as electron,proton etc.This is important in studing how dark matter can effect on our life.This is from website http://www.nasa.gov/mission_pages/GLAST/main/index.html.

GAIA

The european space agency project ,Gaia (Global Astrometric Interferometer for Astrophysics)will test Albert Einstein's theory of general relativity to the limits when it checks the perturbing effect of gravity on starlight to better than one part in a million. Gaia is a mission that will conduct a census of about one thousand million stars in our Galaxy. It will monitor each of its target stars about 70 times during a five-year period, precisely charting their positions, distances, movements and changes in brightness. Gaia is expected to discover hundreds of thousands of new celestial objects, such as extra-solar planets and failed stars called brown dwarfs. Within our own Solar System, Gaia should identify hundreds of thousands of asteroids.It will be launched on december 2011 (Soyuz rocket from French Guiana).Gaia's measurements will be so accurate that, if it were on Earth, it could measure the thumbnails of a person on the Moon.Estimates suggest that Gaia will detect about 15 000 planets beyond our Solar System. It will do this by watching out for tiny movements in the star's position caused by the minute gravitational pull of the planet on the star.-By www.esa.int

This is my kind of search. We can find dark matter by next mission after this mission.There is another experiment LHC(Switzerland),which may detect new unknown particals.

Dark matter-Relation with some supernatural things related to a person.

This year scientists explain a mysterious "force" called dark energy that is responsible for expanding the universe at an increasing pace and was only discovered about 10 years ago.

Scientists say that in few years they may able to explain the dark energy. A new method this year confirmed its existence, suggesting the force is stifling the growth of galaxies in the universe. Basically, in an expanding universe dominated by dark energy, galaxies fly away from one another rather than mingle and merge.

These results also suggest dark energy takes the form of what Einstein called the cosmological constant — a term in Einstein's theory of general relativity that represents the possibility of empty space having a density and pressure associated with it. -Space.com

According to Einstein if dark matter is related to empty space,then the misterious thing that make effects on us (my first post)is something that ,that make effects on us or indirectly give reflection of one's mind to everywhere all the time.Or this may not be related to dark matter or with the thing that Einstein called dark matter.
But there can only two things occur in space matter and antimatter.So the possibility is that the thing ,which i am taking about is related to any of these two matter and antimatter,but it spreads immmidiatly in space and no matter can be discovered till yet having this property,so i can say that this thing is related to antimatter or any alien world.

Detection of dark matter

"A new computer simulation of the evolution of a galaxy like our milky way it might be possible to observe high-energy gamma-rays given off by dark matter."

"These calculations finally allow us to 'see' what the dark matter distribution should look like near the Sun where we might stand a chance of detecting it," said Simon White.He is director of the Max Planck Institute for Astrophysics.

According to scintists NASA's Fermi Telescope should search in this part of the galaxy to get a signature glow of dark matter. -space.com

I think that other effects of gamma rays should work on dark matter and we can detect it not only by telescope but by other sensitive equipments as this dark matter can exist anywhere around us and make effect on us.

Possible nature of dark mater particles

The one thing is that the dark matter particles seems not to interect with each other so as to form a body and other thing is that they clump togather .It means that there are some neutral particals also that interect between some big dark matter particals i.e. they break from one big particle and joined other big particle so that clumping occur.The big particles may be neutron like particles.We can not detect them as they may be in wave form.
What is the effect of light on this dark matter compared with black hole.
