What is the advantage of "bending time" while traveling long distances in Space?

 Food and oxygen and wear and tear on the physical beings traveling.

Wouldn't you rather get into your spacecraft and not need to take extra oxygen tanks or scrubbers or bedrooms or food or things to process your air and food into something that could be recycled?

So, traveling through time as well as space you get into your spacecraft on your home planet (or wherever) and the next instant you are wherever you are headed too, (even if 100 years have transpired since you boarded your craft). Also, this would allow beings not only not to need food or extra oxygen but also to return the next moment after they left to their families with no time having transpired at all for their families including even if the traveler had had experiences of months or years or even a lifetime while gone.

So, you see the advantage of time travel while traveling through space too now.

So, it's not just something people do here on earth to retroactively prevent nuclear holocausts after they happen by returning the planet to normal ever since Eisenhower bought time and space travel saucers from aliens in the early 1950s in Southern California at the location of what is now called "Edwards Air Force Base" but then it was called "Muroc Air Base".
