Tarun Biswas of the State University of New York has produced a theory on how spiral galaxy rotation curves can form _**without**_ dark matter. Usual explanations of spiral galaxy rotation curves assume circular orbits of stars. Further investigations of one of these models (the spinner model) shows that it can explain the formation of the spiral arms as well. It is also shown that the behavior of the tail of the rotation curve is related to the age of the galaxy.
        Meanwhile here on Cost Rica's Central Pacific coast we have some light cloud and 27 centigrade with 83% humidity. Waves are 3-5 foot with a very light off shore breeze, near perfection! How are conditions in your part of the planet? Comment below, including your location. It is always great to hear the local perspectives from our global community.
