A hologram of a candle will make it appear like a candle is there. Can you illuminate a room with the hologram of a lit candle?
lol Why not? I picture it as an LCD display, probably even more lit than a candle And is this real or hypothetical?
It was 9pm on a Saturday night. Now that I think about it, a TV showing a lit room can illuminate a dark room. So (if/when there is holographic TV), it should be able to do the same.
