Empty Set doesn't exist

If you cant sense it, then it doesnt exist.

You cant see emptiness, therefore emptiness doesnt exist.

Would you consider weak infrared light to exist? No human being could sense it with their senses alone, but they can build instruments that pick up the infrared light and depict its presence to a user via an interface compatible with their senses.
Yes. It exists as long as you can detect using some device. For example, world in video game exists (even if in computer memory), in as sense, that you can detect it using video display.
