Future Space
If we managed to swap time and space, the whole Universe would turn into a chaotic collage of many historical events. Imagine drawing a light bulb on a sheet of paper. Then grab one more sheet and draw how it lit up. Right now, it’s just a small circle of light. Another sheet — the circle of light is growing. We see how over time, the light has grown from a small dot to a large circle, and it looks like a cone – a light cone. So, what will happen if this cone approaches a black hole?
