A scientist reports the detection of an atomic particle known as a cosmic ray that came toward his experiment from outer space at a speed of 4 × 105 km/ s–1. What conclusion can we draw from this report?A scientist reports the detection of an atomic particle known as a cosmic ray that came toward his experiment from outer space at a speed of 4 × 105 km/ s–1. What conclusion can we draw from this report?

We can assume or conclude that he must have made an error in his experiment. This is because, that kind of speed has been tagged to be impossible by a number of previous experiments. Cosmic rays are high energy protons and atomic nuclei that moves through space at a speed just close to light. They can come from the sun, distant galaxies and even outside if our solar system.
