Notice to lovers of SnapchatFutura is launching a brand new children’s series on space and the sciences of the Universe: Swipe Into Space. Through dynamic episodes of approximately three minutes, sprinkled with grandiose illustrations and face-to-face sequences, you will discover many mysteries of the cosmosof the edge of the universe to the formation of our planet.
Each week, Thibaut at Futura will answer one of the many questions we might ask. VSow was the Moon formed? What is the Starshipthis rocket new generation that promises to send men to Mars? How does a spacewalk take place? What fate awaits our Universe? What if we could travel to the speed of light ?
On the program of the first episode: the speed of light
In this first episode of Swipe Into SpaceThibaut proposes to study a well-known constant in physicalthe speed of light. It is one of the pillars of special relativity: nothing can surpass it! called ” vs ” in physics, which designates the speed of light in vacuum (c = 299,297,456.2 km/s), the fact that it is a constant allows astronomers to calculate great distances in the Universe, based on the path taken by light to reach us.
This is where unity comes from light year, which is indeed a distance, and not a unit of time! It corresponds to the time that light travels in a vacuum in one year, i.e. 9.461 billion kilometers! To learn more about the distances that separate us from other stars, such as the Moon, the Sunor even the nearest star system Proxima Centauriyou will have to go directly to the page of Swipe Into Space !
