Isaiah Measured Heaven at Five Hundred Years and Found God Nearby
The distance from earth to heaven is five hundred years on foot. Isaiah's discovery was that God answers before the prayer reaches the ceiling of the room.

Five Hundred Years of Walking
Rabbi Yehuda ben Rabbi Simon made the calculation once and left it standing. From earth to the first firmament is five hundred years of walking. The number is not meant to be navigated. It is meant to exhaust the legs before the journey begins. A person could set out at birth and walk their entire life without arriving. The sky that seems reachable from below is, by the rabbis' measure, the beginning of an ascent that no human body could complete.
Devarim Rabbah opens with a question from Deuteronomy 4:7: who is a great nation that has God near it, as the Lord our God is near to us whenever we call? The word near is the problem. If heaven is five hundred years away, nearness requires a different explanation than geography.
The Idol in the Room and the God Beyond the Sky
The rabbis offered a comparison. A carved idol may stand in a person's house, close enough to touch and dust. The worshipper cries out. The idol does not answer. It cannot answer. Its nearness is physical and its distance from the person is total. There is no transaction between them, no recognition, no response.
God is, by measurement, beyond any physical reach. But when a person stands in prayer and calls out, the response comes. Psalms 65:3 provides the line the rabbis trusted: You who hear prayer, to You all flesh comes. The idiom of coming in that verse is not physical travel. It is what happens in the space between the speaking and the hearing. Distance collapses at the first honest word.
The Gap Between the Letters of Shema
Rabba bar Abbahu pressed the practical case. Some acts must touch each other without any gap between them. The Shema is said twice daily, morning and evening. The first verse and the second verse must follow each other without interruption. No pause, no distraction, nothing inserted. The rabbis called this nearness by another name: the kind of closeness that can be demonstrated by how two things sit next to each other in time.
God's nearness to Israel in prayer is the same kind of closeness. Not the nearness of an object that can be picked up, but the nearness of something that arrives the moment it is called. The five hundred years of sky remains. The measurement does not change. What changes is that measurement does not govern the transaction. Isaiah knew God's voice filled the temple when he stood in it. He had no need to travel five hundred years to be heard.
The Common Person at the Gate
The tradition asks whether prayer is accessible to everyone or only to the great. The answer it gives is built from the structure of the comparison. The idol is accessible and useless. God is distant and available. Accessibility is not a function of physical location. It is a function of the readiness to hear. A common person, without rank or achievement or special standing, standing in a courtyard or a field or beside a well, calls out, and the one who hears prayer hears it.
