We have
seen in the MCU movies that the advanced civilizations like the Kree, the
Skrull and the Xandarians have technologies to communicate over very large
distances in space. How large? As I have explained in a previous article, the
field of operations of these civilizations is probably extended over one galaxy
(our galaxy, Milky Way), or a few nearby galaxies. This means, the distances to
be covered can range from a hundred thousand to several million lightyears. How
do they communicate over such distances in real-time?
Let me
elaborate the problem. The communication must happen by using some
electromagnetic signal. But such a signal travels at lightspeed. So, there is
no way that the signal can establish a real-time communication across millions
of lightyears of distances. Then, how does the communication happen? We shall
find an answer here.
As I have
explained in the same previous article, the advanced civilizations use an
established space-traffic system — the jump point technology — to travel vast
distances within their field of operations. This technology consists of a vast
grid of wormholes, connecting the destination places. The openings of this grid
near the destination places are seen as the jump points. In my theory, the
civilizations use the same technology for communication also. When they send a
signal, it reaches the nearby jump point at lightspeed. From there it travels through
the grid to reach the jump point nearest to the destination. Then it exits the
grid through that jump point, and travels through regular space again to reach
the receiver.
I believe
that all Kree soldiers compulsorily learn the basics of this technology as a
part of their training. When Carol Danvers (before becoming Captain Marvel)
came to earth as a Kree soldier, she was able to manipulate a telephone to
communicate with Yon Rogg. Later she also modified Nick Fury’s pager such that
it was able to send signal to her even when she was at a distant planet. These
actions imply that she must have rewired/reprogrammed the devices in such a way
that these were able to generate a signal which could enter the jump points. As
shown in the movies, there is a jump point in the outer space very close to
earth. Her modified signal must have contained some special code that would
allow the signal to enter this jump point.
Instead
of the above method, can the civilizations use quantum entanglement or tachyons
to achieve superluminal communication through regular space? The answer is,
‘No.’ The fact that quantum entanglement cannot be used for real-world
superluminal communication is not a technological limit, but a limit of
fundamental physics. Still, for the sake of the story, let us consider for a
moment that it is possible. But then, Carol would never have been able to
modify the earth-made devices to send such a signal. Since old earth-made
devices are used, the signal is definitely a regular electromagnetic signal.
What do
you think about this possible method for intergalactic communication? Do you
have any other method in mind? Let me know in the comments below.
P.S.
Communication in the Whole Universe
This
method I have described here allows communication to happen only within one
galaxy or a few nearby galaxies — where the jump point technology is
operational. When Carol was a Kree soldier, she traveled only within these
galaxies. So she must have modified Nick Fury’s pager in the above method to
keep communication only within these galaxies. But, as mentioned in Avengers
Endgame, currently she operates in the entire universe. How can she still
receive signals from the pager then? I shall write about it in a future post.
