What is a Peribang? A perigee and an apogee are the specific terms for a periapsis and apoapsis with reference to the Earth. So, the periapsis of something orbiting the moon is called the perilune, and for the sun it’s the perihelion.
If everything originated from the big bang, then I considered that all matter might be in some sort of orbit. So, a peribang would be the periapsis relative to the big bang if we were in orbit around the origin.
The only problem with this is that scientists have observed the universe expanding at increasing speeds which defies Newton’s third law and rules out the possibility of us being in an orbit. Oh well, it’s still a cool name.
