About things that still do not understand

What is life? How to explain an event so subjective?
The scientist Albert Einstein said and proved that all energy can be transformed into matter.
But this theory revealed by this amazing scientist can be applied to life?
For life is a manifestation of pure power latent in people, though that is a personal interpretation, sometimes I get confused because the fact that we know that life exists, it is not possible to explain it objectively.
Extracting dreams (subjective) of each person into a new experience and true (objective)?
In fact, when analyzing realize how true it was Einstein, as we see people who believed and fought to realize their dreams.
But if the theory is correct, why some realizing their dreams and not others?
Must be that old human dilemma, the universe is filled with clean, renewable energy, only that humanity does not have the technology to extract it, using old and polluting fossil fuel.
So are we, resigned and settled, routinely insist on living the same paradigm, inherited from past generations.
Ignoring the discovery of a great scientist, that could be applied not only in the fields of physics, but in our own lives.
Thank you for reading until the last paragraph.
