Through the use of advanced telescopes and scientific models, we're gaining a deeper understanding of the universe. However, to gain a complete comprehension of the cosmos, we must unlock the long-held secrets that have eluded us for centuries. Among the most profound mysteries in modern physics is the nature of dark matter, an invisible substance that comprises the majority of the universe's mass. For decades scientists have been trying to figure out what dark matter is and how it behaves, but unfortunately until now we have not found enough evidence that could confirm the existence of this invisible substance. The existence of dark matter is still just a theory, providing us with a better scientific model to understand the collisions and formation of galaxies or stars. However, Some people don't believe in dark matter. They suggest alternative theories that say we don't actually need dark matter. These theories claim that we can explain observations with the help of alternative theories of physics or gravity. Well, there are many cases where the dark matter theory has also failed to explain certain cosmic phenomena. So, does dark matter really exist? Or do we need to reconsider our Current theories? 0:00 introduction 2:02 What EUCLID scientists said 3:17 Mission Objective 4:30 dark matter and dark energy 6:17 First Images of Euclid #Euclid #Euclidtelescope #Euclidimage #Euclidfirstimage #darkmatter #darkenergy #webbtelescope
