Cosmic Revelations, folks. A survey of over 1500 supernovas by the Dark Energy camera has stirred up questions about the standard cosmology model. The findings hint, Dark Energy, the force behind the universe's accelerating expansion might vary in density over time. This survey, a part of the Dark Energy survey, gifted us the largest supernova sample collected by a single instrument. Type Ia supernovas, the result of white dwarfs in binary systems going supernova, were used as standard candles to measure the universe's expansion. These results suggest Dark Energy's density might not stay constant as the universe expands, challenging the Lambda CDM model. Further research is required to comprehend the enigma of Dark Energy, stay curious, stay questioning.
