Data from the European Space Agency's Very Large Telescope, the most precise made of an effect known as cosmic shear, suggests dark matter may be significantly less dense and less lumpy. The shear effect is caused by super-large structures in the Universe. These findings are in disagreement with earlier results from the Planck probe. Future missions such as the Euclid satellite and the Large Synoptic Survey Telescope may provide an even better understanding of this data. I read this in the article entitled Dark matter may be smoother than expected at Astronomy Now.
Not so lumpy darkness?
