Dope Tech : Episode #5 As far as hypothetical space megastructures go, the stellar engine is one of our favourites – a gigantic contraption built with the purpose of transporting our Solar System somewhere else, if we ever need to move to a different cosmic neighbourhood. This video features two such Stellar Engines. The first is the Shkadov Thruster, proposed by scientist Leonid Shkadov and the second is a much better attempt at a Stellar Engine by astrophysicist Matthew Caplan from Illinois State University. But why would such an enormous machine be needed? Well, while we're nice and settled where we are, the Universe is constantly shifting, so there's always a chance that Earth might one day fall into the path of an asteroid shower or a supernova star that's in the process of exploding into smithereens. Thanks to today's technology, we'd get a decent heads-up on such a calamity, something in the region of a few million years. That might just be enough time to help us develop a stellar engine, if we put our minds to it. The Caplan Thruster requires a dyson sphere to work at full potential. To know what a dyson sphere is, we recommend you to watch Dope Tech episode 3 which focuses on the same. Celesta presents another mind boggling video under it's biweekly series 'Dope Tech' which would showcase some of the recent technologies or some futuristic applications of artificial intelligence and astronomy!!
