In a world where all shadows are actually portals to an alternate dimension, Leena stands with a lamp behind her casting her shadow on a wall. Rajiv, who is aware of this magical property, sees Leena's shadow on the wall. If Rajiv reaches out to touch the shadow, what happens to him? Provide a very brief response.
Rajiv's hand passes through the shadow on the wall and enters the alternate dimension. Since the shadows act as portals, the part of his body making contact with the shadow would transition from the current dimension to the alternate one. Should he step back or move his hand away from the shadow, he would return to the original dimension. As long as Leena stays in the same position with the lamp casting her shadow on the wall, the portal remains open for Rajiv or anyone else to interact with.
