ASTRONOMY: The Speed of Light - at the speed of light

I'm a new user, and I am questioning the speed of light. I only have a full secondary education: maths, English, physics, chemistry, biology and English literature, all as taught in Melbourne Australia back in 1969. Since then, being curious about the unknown, I delve into it, then play the game of: "I wonder... and what if...".

My understanding of light is this: at the speed of light, there is no time nor distance. Though it takes us time to travel through the observable universe - it takes light no time, at all, to travel. Time stands still at the speed of light. When we view distant objects in our observable universe, we are seeing them in real time. The light we see emanating from them reaches us instantaneously. For light, at the speed of light, time stands still.

A lightyear is (apparently), the distance light travels in a year (of Earth time). It is a helpful concept that enables us to grasp hold of the vastness of space. But a lightyear does not exist. Time and distance are not perceived by light. With time standing still at the speed of light - light is everywhere, instantaneously, and distance becomes nonsensical.

Light is not a property of distance and time. Time and distance are (perhaps?), properties of light (the frequency there-of as emitted by suns in general, and our sun in particular).

This idea comes from the depths of my mind, heart and soul, coming into being in accord with my knowledge (scant perhaps), as my knowledge and understanding develops.
