Avi Loeb: Interstellar Trash Could Lead to Finding Alien Life

What is space trash? Dr. Avi Loeb, Professor of Science at Harvard University, explains how the objects we send into space will become space trash in 10,000 years once they exit the solar system and become non-functional. He also says that if we can find space trash from previous alien civilizations, we will be able to study it! He believes that there is high potential to find proof of extraterrestrial life, because we haven’t looked yet using instruments specialized to finding life.
