Aliens Among Us
The question “Do We Share Our Planet With Alternate Lifeforms?”. According to mathematical studies, there is a 95% possibility that life has evolved on Earth twice or more. Natural principles provide no justification for why life couldn’t have originated from more than one place. Although DNA-based life predominated, RNA-based life did not completely fill all available niches (DNA based life uses RNA, and evolved from RNA based life). Currently, the majority of our methods for finding life tend to focus on DNA rather than RNA.
Large planetoids, comets, and meteors would have pounded the Earth in the early Earth’s history; some of these objects may have wiped out the earliest forms of life. Life would have started over. Why? If the kind, quantity, and environment (temperature, pressure, etc.) of the chemicals involved are known, why may chemical reactions be predicted? Why can huge physical systems—and thus Newtonian ones—be predicted from known quantities like mass, density, magnetic fields, etc.? because rules apply everywhere. Life will increase under a specific set of circumstances.
On Earth, there is a wide variety of life, “but they are staggeringly uniform at the molecular level” (62). This does not imply that life on other planets will be uniform like life on Earth. However, it will likely have a unique homogeneity. And it does imply that we need to expand the toolkit we employ when hunting for life. But it also means that in order to understand the fundamental biological principles, we must study every type of life that exists on Earth.
As you can see, forces interact to achieve equilibrium. Gravitational compression causes a star to burn, creating a nuclear firestorm. The pressure of that furnace’s radiation resists the pull of gravity. The star burns in a general steady state as they balance. The length of the star’s life and whether it ends in a supernova or a blackhole depend on its mass (OK, this is a bit oversimplified). This occurs repeatedly throughout the universe because the forces are everywhere. For example, gravity, light, and electromagnetism are all present and react in accordance with their individual natures. Because of this, the forces do not interact randomly throughout space and time. For instance, gravity does not randomly transform into light and then into magnetism, nor does it randomly alter how it interacts with the universe.
Although there is controversy over how consistent certain constants really are, it is still true that general forces have a nature and a pattern to them. Additionally, patterns can interact with one another to produce a wide range of outcomes; yet, this is not chaos. similar in biology. There will be common biological principles. Just as stars die and are born; they did not come into being only once, to die as a singular occurrence. And given the correct range of conditions, life will arise repeatedly throughout the universe. Galaxies were not just generated once. Even if the cosmos is slowly evolving and change may be the only true constant, life is currently here and we are discovering more and more about how resilient it is. Certain living forms may not survive, yet life itself tenaciously endures horrible catastrophes and disturbances.
