Light speed is fast😱

#Repost///@glamour_physics: Light travels in a vacuum at an incredible speed of about 300,000 kilometers per second. This is also considered the cosmic speed limit. The speed of light is a fundamental constant of nature, the highest speed at which anything in spacetime can travel. Even if we could travel at the speed of light, it would still take millions or billions of years to reach some places in the universe.The universe’s vast distances are measured in light-years, one light year is the distance that light travels in one year in space, about 9 trillion kilometers. The nearest star to our solar system is 4.3 light-years away, while the Andromeda galaxy is 2.5 million light-years distant. The observable universe is 93 billion light-years in diameter, meaning the farthest objects we can see are 46.5 billion light-years away in any direction. So that means even if we could travel at the speed of light, it would take 4.3 years to reach the nearest star system, 2.5 million years to reach the Andromeda galaxy, and 46.5 billion years to reach the edge of the observable universe. The vastness of the universe is truly humbling.👉Share your thoughts in the comments, if you read the caption!🎯Follow us for more informative and interesting videosTag a friend who needs to see this!:)🎯 Collaboration with @modernsciencex🎯Follow us for more interesting posts@glamour_physics@modernsciencexVideo editing and processing : @glamour_physics@modernsciencexVideo clips credit used in the video: NASANova._Space ( Solar system video) Music credit: Vengeance- iwilldiehereAll rights reserved For respected owners content is used for educational purposes only. Copyright issues?
