Dark Matter News Update- Not discovered


Yesterday, Samuel Ting presented the results that he got from AMS (mentioned in my previous blogs) and indicated that the information does not show signs of Dark Matter. Their results show that AMS has detected an excess of positron that may indicate the existence of dark matter (this is not the first time people find excess positron). However, the data are not conclusive enough, and the researchers need more time analyzing and collecting data for precise conclusions.
Other than the news that dark matter is not found, the data published indicate that the AMS experiment currently have the best set of experimental data, as you can see from the plot below. :)
To state dark matter has been found, the last curve will have to go down and to form a hill, but it doesn't. (This can be dark matter or pulsars) The data after the last point still need more analysis and samples, so they are not published or considered for the conclusion.
