🚀 Can We Reach Andromeda in Minutes? | Speed of Light & Relativity

Can we travel to the Andromeda Galaxy in just a few minutes?! Famous physicist Brian Cox explains that at the speed of light, distances shrink dramatically for the traveler. This phenomenon has been confirmed at CERN, where a 27-kilometer track appears to be just 4 meters for protons moving at 99.9% of the speed of light! If we could build a spaceship capable of traveling at the speed of light, we could reach Andromeda in minutes—while for observers on Earth, the journey would still take over 2.5 million years! But there’s a big problem: if you return, Earth will have aged 5 million years… Will such travel ever be possible for humanity?! 🔔 Subscribe for more science videos! #Physics #SpecialRelativity #AlbertEinstein #BrianCox #SpeedOfLight Music by Karl Casey @ White Bat Audio YouTube Channel:    / whitebataudio
