When Mercury is in retrograde, it appears to move backwards from our view on Earth due to an optical illusion caused by differences in orbit. This is an astrological concept that has negative connotations, particularly for communication and technology, according to astrologers. However, there is no scientific evidence to support the idea that Mercurys retrograde motion has any impact on individual human behavior or events on Earth. During Mercury retrograde, it is advised to avoid making important decisions or initiating new projects, as it can be difficult to get decisions from others and plans may be subject to change. Some people believe that Mercury retrograde can cause miscommunication, delays, and other misfortunes. However, it is important to note that these beliefs are not supported by scientific evidence.
