Can you feel this Loneliness?
Are you alone? Are your family is alone? Your friends? Your co-workers? All of us.. Can you imagine how huge is the space around us?
Everyone know that the Sun is large and the Earth.. is not large enough and that it is impossible to fly to the nearest star or to the nearest galaxy by rocket. But can you imagine these distances?.. 1 000 000 000 000 000 000 kilometers?.. Can you feel the difference between this distance and 1 000 000 000 000 000 km for example ?
So, let´s imagine that the Sun has the size of football..
It´s easy to imagine right? May be it is because size of football is comparable with the size of our brains ? =) So, if it will be so, then Earth will have raduis = 1mm! It is a grain of sand! And between this grain and this football will be the distance about 23 meters! It´s so far.. But we have some tiny planet satellite near us - the Moon which will be 0.27mm and it will be spin around Earth with distance 6 centimeters! Jupiter will have radius 1.1 cm and will have distance to the sun 123 meters! Hey, can you imagine cherry and football with this distance? And this cherry is spinning around this football too of course, like Pluton´s grain with the distance about 1 kilometer. There is nothing between these balls. NOTHING! Only several another balls with radius not more than cherry. We call it Solar System and know that here is no one live outside the Earth - grain of sand on the field with radius more than 1 kilometer. I can´t understand how satelites that fly from Earth can find here something.. something like a cherry or like another grain of sand.
But this is only our star system.. And there are another stars of course. The closest of them - Proxima Centauri will be situated 6 000 km away from the football.. It´s like the distance to Africa from the Eastern part of Russia. And there is NOTHING! between Proxima Centauri and the Sun.. Only space and some radio and TV noise from the Sun´s direction =)
The largest of known stars Mu Cephei will have radius 250 meters! It is the same with Saturn´s orbit.
To the center of the galaxy will be distance that is so hard to imagine - there become a lot of zeroes again. So from the football to the center of our galaxy will be 37 000 000 kilometers. And from our galaxy to the nearest will be distance 3 500 000 000 kilometers. If this values turn to the football sizes again and imagine that our galaxy is one football and the nearest galaxy (Andromeda Galaxy) is another football then the distance between them will be about 1 kilometer.. I feel space around us. Like a mosquito at the stadium.. But sometimes some mosquitos find another mosquitos… May be we can find another mosquitos too ? =)
And here are some bonus:
Here is comparision of planets like this:
