THINGS THAT SHOW HOW PRECARIOUS LIFE REALLY IS

OUR GALAXY’S SIZE

According to science, our galaxy is in the top one percent

of the most massive and luminous galaxies in the universe

and is the perfect size to sustain life. Not too large, since

in this case the infusion of gas and stars would disturb the

sun’s orbit and ignite deadly galactic eruptions and not too

small, where the infusion of gas would be insufficient to

sustain star formation long enough for life to form.

IDEAL VOLCANIC ACTIVITY

Believe it or not, if Earth had less volcanic activity. it would

produce insufficient amounts of carbon dioxide and

water vapour would return to the atmosphere. That means

soil mineralization would be insufficient for advanced life

support. On the other hand, if we had too many volcanoes

erupting then advanced life would be destroyed and the

ecosystem would be fatally damaged.

H+ 3 PRODUCTION

The trihydrogen cation, also known as protonated molecular

hydrogen or H+3, is one of the most abundant ions in the

universe. It is stable in the interstellar medium (ISM) due to

the low temperature and low density of interstellar space.

The role that H+3 plays in the gas-phase chemistry of the

ISM is unequalled by any other ion. If, however, it were

less than it is now, simple molecules essential to planet

formation and life chemistry would never form. If it

were too great, planets would form at the wrong time

and position in space for life.

AXIAL TILT

In astronomy, axial tilt is the angle between a planet’s

rotational axis at its north pole and a line perpendicular

to the planet’s orbital plane. It is also called axial

inclination or obliquity. Earth’s axial tilt causes the

seasons. If, however, it were greater or less as it is on

most other planets in our solar system, then surface

temperature differences would be too great to sustain

diverse life-forms, including human life.

THE IDEAL IRON QUANTITY IN OCEANS AND SOILS

Once again, there are some things we take for granted. If for

some reason the iron quantity in the ocean and soil were

greater than it is now, iron poisoning would destroy advanced

life. If it were less, then food to support advanced life

would be insufficient.

THE QUANTITY OF SULPHUR IN EARTH’S CORE

Research in 2015 confirmed that Earth’s core contains very large

amounts of Sulphur, estimated to be up to 8.5 x 1018 tons.

This is about ten times the amount of sulphur elsewhere

on the planet and to compare, is around ten percent of the

moon’s total mass. What does this mean? Well, if there was a

larger amount of sulphur in Earth’s core then a solid inner

core would never form, disrupting the magnetic field and

making life on Earth impossible. If it were smaller than

what it is currently, solid inner core formation would begin

a little too soon, causing it to grow too rapidly and

extensively, also disrupting the magnetic field.

THE LOCATION OF OUR SOLAR SYSTEM

The location of our solar system appears to be another

important factor that allows Earth to harbour life. Our

solar system is located very far from the centre of the

galaxy, where there is a great black hole, many stars

burn out and supernovas that kill off life and between

the spiral arms, which puts us far from the supernovas

and give us a great view to study and observe the universe.

THE MAGIC OF GRAVITY

Even though we take gravity for granted, the truth is that

without Earth’s gravity, human life wouldn’t exist. Gravity is

responsible for giving weight to all that is found in our planet.

This means gravity allows rain to fall and water to drain,

air movement and even heat dissipation. Furthermore,

it’s believed gravity is a major contributor to biological

changes such as the evolution of species from water to land.
