In future deep space missions the distances are so vast that there will be a delay in communication with Earth. That delay will vary from a few seconds at the Moon to many minutes on potential future Martian missions. Living with latency throughout long duration missions will affect operational communications and also the crew’s personal relationships with their loved ones on Earth.
This is where Space Braiding comes in. We can’t remove the latency, as it is created by a fundamental law of physics, but we can disguise the latency. We can make two people separated by millions of km feel as if they are having a natural, synchronous, dialogue.
