Abstract: We can observe deviations in the behavior of galaxies from Einstein’s general theory of relativity when we consider only baryonic matter. They are explained by dark matter and dark energy. Is there any other explanation?

Are black holes proof or disproof of the law of conservation of information?

The rotation curve of the typical spiral galaxy M33 (yellow and blue points with error bars) and the predicted one from the distribution of the visible matter (white line). The discrepancy between the two curves is accounted for by adding a dark matter halo surrounding the galaxy. Though dark matter is the most accepted explanation of the rotation problem, other proposals have been offered, including Modified Newtonian Dynamics (MOND) and this new theory of Emergent Gravity.
