"The factor most ignored in discussing interstellar flight is the kinetic energy that must be invested in the ship to make its tons of matter move at a substantial fraction of the speed of light"

This quote by Barney Oliver is referring to the fact that interstellar travel needs a big amount of energy to propel a ship at a considerable portion of the speed of light. This is frequently ignored when talking about interstellar flight, as the focus is typically on the technological advances required to make such a journey possible. Nevertheless, the kinetic energy needed to move a ship of lots of matter at a portion of the speed of light is immense and need to be thought about. This energy needs to be bought the ship in order to make interstellar take a trip a reality. Without this energy, the ship would not have the ability to reach the speeds needed to make interstellar travel possible. Therefore, the kinetic energy required for interstellar travel is an important element that must not be disregarded.
