Efforts to Search for Extraterrestrial Intelligence

Scientists are actively searching for extraterrestrial intelligence through various methods, including listening for radio signals from space. The search involves using radio telescopes to pick up potential signals among the noisy background of the universe. Finding an alien signal would be monumental for science as it could indicate the presence of extraterrestrial life. However, challenges exist due to the abundance of natural radio wave sources and the need to differentiate potential alien signals from human-made interference.
