NEW VIDEO: Stellar Engines
Added 2019-12-22 13:45:01 +0000 UTCNothing in the Universe is static. In the milky way, billions of stars orbit the galactic center. Some, like our sun, are pretty consistent, keeping a distance of around 30,000 light years from the galactic center, completing an orbit every 230 million years. This dance is not an orderly ballet - more like a skating rink filled with drunk toddlers. This chaos makes the galaxy dangerous. Our solar neighbourhood is constantly changing, with stars moving hundreds of kilometers every second. Only the vast distances between objects protect us from the dangers out there. But we might get unlucky in the future. At some point we could encounter a star going supernova. Or a massive object passing by and showering earth with asteroids. If something like this were to happen we would likely know thousands, if not millions of years in advance. But we still couldnβt do much about it. Unlessβ¦ we move our whole solar system out of the way.

Nice video. Have heard about the Iter project ? If yes , will you intend to make a video about this project ? thank you for hard work. Wish you to be more reconize , more patreon off course and the essential : be happy : )

2019-12-23 16:28:08 +0000 UTCIs it exactly counterbalanced or the photon's push is a little bigger than the gravity's pull?
Vipul Kapoor
2019-12-23 11:22:14 +0000 UTCGravity pulls the mirror and the sun closer together. But this is exactly counterbalanced by radiative forces (because we design the mirror carefully). Therefore, we can treat the sun and the mirror as a single system. That single system moves because of the photos reflected "around" the sun.

2019-12-23 10:03:33 +0000 UTCI don't get one thing about the mirror. Why wouldn't it just get pushed away from the Sun? How would Sun get tugged along with it?

David Durant
2019-12-22 15:14:58 +0000 UTCYou asked your friend... For this video... And he got it peer reviewed and published. Dang! Sounds like an awesome concept! I wanna see a TV show or movie pick up this idea and run with it.
