But what do aliens actually look like? On this score, scientists have quite reasonable ideas.
Researchers believe that external diversity is actually quite severely limited by the laws of the universe. Astrobiologist, professor at the University of Edinburgh Charles Cockell, author of the book “The Equations of Life: How Physics Shapes Evolution” names three restrictions that all life forms, without exception, must follow.
“Physical laws are the same everywhere. For example, the force of gravity acts not only in the solar system, but also outside it.
The conditions for the existence of organic molecules are the same everywhere. On Earth and beyond, organic molecules break down at high temperatures and cease activity at low temperatures.
In every corner of the universe, life will use the same ingredients. Carbon is the optimal chemical element for the origin of life, and water is the ideal fluid for its transport.
What does this mean
in practice? We know that there are three aggregate states of matter:
solid, liquid and gaseous. And if the habitat of aliens is gas, then
they must comply with the laws of aerodynamics....<<Read More>>>...
