“Escape Into A New World Of Science” by Shiva Deb

Dark matter does not exist !!


The picture below is a white napkin with some black dots on it. Consider all the black dots as stars and the napkin as fabric of space.









Now I place a clip exactly in the middle of the napkin. Consider this clip as a powerful force at the centre of a galaxy.





Now, if I rotate the clip, the napkin along with all the black dots present there will become twisted as shown in the figure below.





And the most important thing, if I rotate the clip further the whole napkin (space fabric) will start rotating with the clip including dots (stars) closer to the centre and dots (stars) far away from the centre, near the edges and that’s why stars revolve around their galaxy's centre at equal or increasing speed over a large range of distances. Now, if I carefully remove the clip, then the picture will look like this-





Don’t you think the above picture looks like a spiral galaxy !!
