 This equation is entirely correct theoretically and completely logical experimentally.
 What has always amazed me, for several years now, is that I have remained one of the few to fully trust it, even though the observed effects can sometimes be frankly counterintuitive.
 I remind you, once again, why I remain the best relativistic theorist of all time (not by my own strength, because I based my work on my predecessors, and I confirm that the mathematician Henri Poincaré was the greatest and the true founding father of the theory); I am the only one who doesn't tremble when writing what he writes:
All the others start to tremble if I ask them how far the Earth is from Stella's spacecraft, when Stella has just made its U-turn, over there, at Tau Ceti, and is now traveling towards Earth at 0.8c.

Have you heard of something called 'acceleration'?
In flight they use the term 'g-force' as a measure, how fast a pilot could be accelerated.
Such an u-turn at 0.8 c would require to decelerate to almost zero speed and accelerate again.
You could try an u-turn at almost light speed, but that isn't recommended, because turning causes a sideways acceleration (called 'centrifugal force') and pilots cannot withstand more than a few g.
It depends a little upon the radius of your turn. But at 0.8 that radius needed would be rather large.
So deceleration would be mandatory.
Unfortunately that also threatens the health of your crew, if higher than two or three g.
But the distance to that star should be long enough to safely accelerated and decelerate.
The main problem is now, that the crew wouldn't live long enough for a round trip.
