Even mathematically it doesn’t make any sense: we would need to go to a causally disconnected region of spacetime to be able to go faster than the speed of light, but that’s just not feasible. Once you go to that causally disconnected region of spacetime, the only outcome is to go to a singular point in space (even though you can go back and forth in time, theoretically at least) : if that sounds familiar to you, it’s because it is well represented into the movie «interstellar» and indeed he goes to a region causally disconnected to ours: a black hole.
Or that the only thing standing between humanity and the ability to build space craft capable of colonizing other planets is getting the right numbers to plug into a ‘gravity equation’?
Having been sold on the movie by people telling me the science was “realistic”… the reality was disappointing.
> getting the right numbers to plug into a ‘gravity equation’
Those are what I like to call "load-bearing" numbers. :)
There's so much science daydreaming in what passes for the science press that people think all of our problems will be solved once the smart people (or quantum computers) find the magic formula and those elusive load-bearing numbers.
Half the people here understand physics, and the sheer impossibility of the task due to the relative magnitudes involved, and have resigned themselves to "we better learn to live on this ball together as it's all we're ever going to have". The other half daydream about magical solutions that marvel movies tell us exist, we're just waiting for an Elon Musk or Tony Stark to discover it and then humanity enters a golden age.
