I recently came across an interesting hypothesis. Our visible Universe is represented under the universe, that is, light from more distant objects has not yet reached us. Consequently, the process of "expansion" of the Universe can be only the "appearance" of the glow of very distant, for example, stars before us. The problem for studying this issue lies in the absence of a subject over which one can experimentally prove the existing hypotheses.
Today, it is impossible to understand such a phenomenon as "infinity" based on the short-term nature of a person's life and the limited capacity of the brain.

I imagine a cube turning inside out. Here it unfolds and unfolds endlessly in four-dimensional space. You can also imagine yourself as an ant walking inside a hollow donut and its path is endless.

Strange, but no one has written the main thing. And space is not infinite! The universe is huge and constantly expanding. It's like a constantly inflating balloon that doesn't burst.

Infinity can be imagined only in time, directed into the unfinished future. For example, if we imagine motion in space that ends in an insurmountable obstacle, this will not correspond to the idea of ​​infinity. If we imagine that this movement never ends, then such a model is the model of infinity. In general, any process that has no end will correspond.

So, the infinity of space can be represented in the form of incessant motion against the background of approaching and receding space objects.

On the other hand, it will only be infinity model. And a model is always a certain scheme, that is, a deliberate simplification. So we can feel infinity, but we have no opportunity to feel it completely, as something complete, it is infinity)))

Here you can see what the solar system looks like on a scale and even fly past the planets at the speed of light (you need to click on the C icon on the right). This is not what you usually imagine after watching popular visualizations with one bigger circle and one smaller circle. After watching, you realize how "slow" the speed of light is, even on the scale of our solar system.
