WHY IS GRAVITY IMPORTANT?
Gravity, the so called weakest 'force,' helps form all the stars and planets in the universe, maintains them in their interactive orbits, and grasps all the collective rocks, liquids, and gases - and in the case of Earth, all life - and retains them together as whole planets or stars. This may seem, to most of us, as perhaps interesting, but not very important to our daily lives.
So why is gravity so important? Well, gravity is the key force driving Earth's orbit around the Sun, and so here we can learn about the seasons. Gravity is a key component behind the interaction of the Moon and the Earth, and so we can learn about the tides. Gravity is a key component behind the flow of water (and all materials in fact) 'downhill,' and so we can learn about gravitational potential energy (such as rainfall). Gravity, or the lack of it's effects under water, can teach us about pressure, and why organisms in the sea can grow bigger and faster than organisms on the land. And as gravity acts upon mass, we can learn about weight, and load. Finally, gravity is also an input for some organisms different senses.
Therefore, this page and blog provides some insights into why a better understanding of gravity is important for designing and developing innovative, efficient and regenerative companies, farms, and homes. We are bringing gravity back down to Earth - and into our design toolbox.
The Main Image
The image above shows the Sun, Mercury, Venus, Earth and our Moon, and Mars (the inner/terrestrial planets), the Asteroid belt, and Jupiter, the closest of the four outer planets.
The planets are shown in relative scale to the Sun (due to perspective in this image Jupiter should be larger, but its scale size has not been altered). The larger, duplicated Earth and Moon, have been enlarged x20. The distances between planets are not to scale.

A Double Planet It is hypothesised that the moon developed out of a interplanetary collision between the young Earth (over 4,000 million years ago) and a huge asteroid, potentially the size of Mars. Vast amounts of matter and energy were released, which later gathered together through gravitational forces to form the moon . Scientific simulations suggest that at the time of its formation, the Moon was much closer than it is today (only around 22,000km away).
The Goldilocks Zone Earth orbits the Sun at a significant distance, which places it within a zone known as the Goldilocks Zone - also known as the Habitable, Comfort or Circumstellar Habitable Zone (which also includes Mars, but not Venus). This zone, as its’ various names suggest, is an area in which it is theoretically possible for a planet, with sufficient atmospheric pressure (due to it's mass), to maintain liquid water (and thus is limited to an
Gravity - Potential Energy In the case of the Earth, our planet is falling into the valley of space-time created by the incredible mass of the Sun - the Gravitational Pull. And as Earth is trying to travel in a straight line perpendicular to the Sun - the Countering Velocity - maintains Earth caught in an orbit around the Sun. And what is true for the Sun and Earth, is true for all the planets in the solar system, the solar system within
Buoyancy Although the gravitational 'force' on the surface of the Earth is more or less constant, the mechanical load on land-life is around 1,000 times greater than in the water. Underwater, gravity is almost cancelled-out by buoyancy: “...the upward force exerted by a fluid that opposes the weight of an immersed object.”  If a body is lighter (less dense) than water, it will float. It floats as the body is experiencing an upward force that is
Let's get our bearings... The Sun At the heart of our planetary system, is the Sun - our hydrogen burning star. Orbiting around it, all in the same counter-clockwise direction, are a number of rocks and planets. These are all orbiting practically in the same reference plane, and rotating about their axises in the same counter-clockwise direction (except Venus and variably Uranus). Mercury The closet planet orbiting the Sun is Mercury. It is the smallest
