Fruit is a fund way of showing the relative size of planets. There is no fruit large enough to represent the Sun. So think of a 1 metre across hoola hoop.
The Sun's diametre is 700,000kms. It could contain Earth over 1 million times. If you were to travel from Earth to the Moon, you would only have travelled half way across the diametre of the Sun.
These distances increase as our solar system expands. Our solar system is rocketing through space at 460,000 kms / hour. We stand on a tiny spinning ball which we can fly around in a day. Our planet is a tiny dot in a vast unreachable infinite space.
Our nearest planet is either Mercury, Venus or Mars; depending on their relative distance to Earth, based on their eliptical orbit of the sun. The Earth moves closer to or father from the Sun as it makes it ways around in an egg-shaped orbit. This changing distance affects our climate and the energy we receive from the Sun and other planets.
As I fly these days, I realize how small Earth is. And how vast Space is. It is a discomforting reality to know that none of the planets in our solar system can sustain life, in our form.
Perhaps why we become so preoccupied with war and atangonism between each other. Because deep down, we know, we cannot escape, and that we are alone, on a tiny piece of metal, carbon and water, within an infinite and largely empty universe.
It is likely, even statistically certain, that there existing trillions of life forms, as intelligent as ourselves. And of course more intelligent. But they are so far away, that it is likely that we shall never be able to communicate with them. Or them with us.
Which means we are essentially that our species will live and burn out, on this planet, alone, with no other intelligent life form to communicate or share with. Even though we known that they exist.
Perhaps it is this bleak reality that leads to the desire to imagine 'aliens' or 'gods' or other 'extraterrestrial' phenomena.
Perhaps it is a reminder that 'now' is important. Because no matter what you do, achieve or create, it will all end in nothing. Worse than not being remembered, is the reality that we, as a species, as a planet, may never be known. Never witnessed. Our existence lost.
While we may reach Mars. It being 290 million kms away, [space travel 290 days]. We already know that Mars is not suitable for human life. Our nearest planet, that has been found to have a goldilocks condition, is Planet Kelper 452b. This holds some promise. It is 1.8 times the size of Earth and in the right zone from the Sun. However, it is 1400 light years away. A light year is 9,460,730,472,580.8 kms.
It would take us 30 million years to reach Planet Kelper 452b.
Since homosapien have only be around for 300,000 years, and are already looking dangerously precarious [the Doomesday Clock is at 90 seconds to midnight], it seems hard to imagine us surviving long enough to make that journey.
30 millions years later:
Astronaut 1: 'Mission control, this is Kepler 9. The Eagle has landed!'
Astronaut 2: 'They can't hear you dumb-dumb, its taken us 30 million years. Humans died out millions of years ago.'
Astronaut 3: 'We got a problem guys.'
Astronaut 1: 'What is it?'
Astronaut 3: 'The oxygen levels aren't sufficient for life. And its raining sulphuric acid. And were out of coffee.'
Astronaut 1: 'We'd better go back fellas".
[Astronauts groan.]
'Tut! Told you so."
So when you see leaders bombing each other, politicians talking big, instead of trying to descalate war, think on. These clowns are playing with our planet. This is all we have.
