Humanity has come in contact with extraterrestrial life. The aliens have wondrous technology and information. They are willing to give us some of what they have and allow us into the galactic federation. But humanity has to exchange humans for “scientific” purposes first. You have been chosen for this exchange. Your government tells you have been selected due to you being young, health, and fit, a perfect subject. You are being flown to a space station where you will live indefinitely.
