That seems a little strong. Still, it’s certainly impossible with current tech, and there’s no method anyone’s come up with to do it with a higher tech level.
It’s not just matter of technology. Such a feat would most likely require a violation of the principle of conservation of energy. While there are still some unresolved issues with renormalization and general relativity, it is generally believed that conservation of energy applies to the universe. The discovery of a violation of conservation of energy (which would imply that the laws of physics are not invariant under time translation) would be a groundbreaking result.
