THE SAME LAWS OF PHYSICS THAT MAKE THE 26-MILLION YEARS IT WOULD TAKE HUMANS TO REACH PLANETS WITH POSSIBLE INTELLIGENT LIFE, APPLY TO WHATEVER LIFE FORMS ARE OUT THERE TRYING TO REACH US. A HIGHLY ADVANCED CIVILIZATION COULD PROJECT HOLOGRAPHIC IMAGES ACROSS OTHERWISE INSURMOUNTABLE DISTANCES. SUCH A CIVILIZATION MIGHT ALSO BE ABLE TO COMMUNICATE TELEPATHICALLY THROUGH THESE PROJECTIONS. DEPENDING ON THE SOPHISTICATION OF THE SOCIETY CONTACTED THESE EVENTS MIGHT BE REPORTED AS MESSAGES FROM "ANGELS," OR UFO SIGHTINGS.
