Einstein says that time and space are inextricably linked in what he called spacetime, so the warping effect of gravity does not just affect space, but also time.

I created this work above a heating plate, imagining each piece of thermal paper as a universe, by folding and bending them, I tried to create a scene of “wormhole” in the space. The uneven black color is the clue, what you see is not just a 2D black and white collage is the trace of temperature changing, space warping, and time passing.
