| 1 | Assume the speed of light is the same for both observers. | |
| 2 | Since neutrinos have a tiny mass, the speed should be very close to the speed of light. | |
| 3 | Finally, Einstein arrived at a conclusion that maximum speed in the universe is that of light. | |
| 4 | And that isn' t flying a thousand miles an hour, or a million, or flying at the speed of light. | |
| 5 | However, we can use relativity as a model to see what happens at speeds close to that of light. |
