Interesting. All of a sudden a deep space radio telescope seems like a good scientific mission. It would be a fascinating discovery if we poked our noses out of the heliosheath just to discover that all of the missing mass in the universe was to be found in cosmic rays that never reach the inner solar system.
- atakan_gurkan 15y agoWe have good reason to believe that the missing mass cannot be baryonic or fast moving massive particles. This comes from the abundance of elements, so it is indirect but is consistent with other findings. Furthermore, those cosmic rays would radiate when decelerated. I think if there was substantial mass in cosmic rays, we would see this radiation (did not make a calculation though). Note that the estimate for the mass of dark matter is about ~5 times the normal matter.
