The blur that appears to be dust around HR 4796A might just be dust that never was, and never will be, a planetary system. We believe there are planets around other stars, but none have been discovered yet . We object to controversial speculation about the cause for oscillating Doppler shifts, or holes in dust clouds, being presented as proof of the existence of planets. We appreciate Newsweek's need to sell more magazines, but that doesn't justify presenting speculation as fact. If people are told enough times that planets have been found, and that they probably have life on them, many people will believe scientists have found life on other planets, even though there is no valid scientific evidence to support it.
Many people already believe that species evolved into other species for the same reason.
Don't be fooled. Read the articles about such discoveries carefully.
