When you look up at the night sky, the photons arriving from distant stars & galaxies have experienced no passage of time during their journey to your eye 💫

From their perspective, they arrive at exactly the same moment that they left & they have travelled no distance ⏰📐

You may now continue your sub-light speed day 🤷♂️

(Yes, my train to Mannheim was late & I made it on to my connecting ICE to Frankfurt Airport thanks only to the conductor who kept his door open for me 🚅😰)
