Scientists inside a science base in the Moon conduct a variety of humorous experiments. We see a cat chasing after a giant laser beam; a scientist being eaten by a venus fly trap, a star falling through a Christmas tree as a scientist tries and fails to put it on top, a scientist going to a 'moonshine' bar, robots attending a seminar, a scientist trapping a human brain in a forcefield, and scientists stepping through portals. In the sky above the spaceship, Santa is being abducted by aliens.

Quantum computer core. Light rays passing through the nanoscale crystal core of a quantum computer. Quantum computers, which are under development, are based on quantum mechanics and the principle of representing information in quantum bits (qubits) using quantum properties. This could involve optical properties of chemically doped crystals, like the one shown here. Quantum computing has the potential to massively increase computing power.
