To protect inhabitants of a space colony from harmful cosmic rays and solar particles, we would most likely need to     place the colony over the far side of the Moon, where it would always be protected from the solar wind     locate the colony in the outer solar system, where the influx of harmful radiation would be minimized     locate the colony in Low Earth Orbit to take advantage of our planet's magnetic shielding     encase the colony in a radiation shield made of lunar rock

Special Relativity

The theory of special relativity discusses how space and time are related to objects traveling along a straight line at a constant speed. Simply stated, as an object reaches the speed of light, its mass becomes infinite and it is unable to move faster than light. This interstellar speed limit has been the topic of much debate in astronomy, and also in science fiction when people consider how to fly over large distances.
