How do you know when you’re far away from something? I mean, what’s your basis? Is it your capacity of walking the distance? Is it the echo of your voice when you yell towards it? Is it the difference of its location and yours? For example, you’re in Philippines. The sun is far, the moon is near. US is far, Japan is near. How can you say the moon is near and US is far when the moon is 384,400km from where you are and US is just 13,727.60km away?
