24.5 Can We Communicate with the Mirror
World?
The existence of a mirror universe always raises the possibility of whether
we can communicate with it. So far, the mirror universe is only a theoretical
construct. Therefore, there has to be a theoretical framework which will allow
this communication. There are several possibilities. In the most minimal class
of models, only gravity is the communicator. But there could be various
other portals, such as light of the two different sectors converting to each
other or even neutrinos doing the same. If the sterile neutrinos are confirmed
experimentally, it may make the second neutrino mode of communication
feasible. That will be a very interesting future possibility. Meanwhile, we may
observe mirror stars and gain some information about the parallel universe.
Is it possible that one may have already seen the imprint of the mirror
world in the periodic extinction of species? The periodic mass extinction of
species is believed to have occurred every 25–30 million years in the past. The
dinosaurs were extinguished about 65 million years ago. If these extinctions
were caused by asteroid collisions, it has been speculated that it could have
been caused by a mirror star with an orbital period of 25–30 million years.
Communicating with the mirror sector may then provide a way to test this
idea. Such communication may also be important in future space travel if a
spaceship is close to one such mirror planet or star.
