I love anything to do with space. Absolutely fascinating. But, I am always cautious about experiments such as these. For one thing not enough is known about what exists in space i.e. dark matter, to create an accurate model of space or the big bang theory. Even standard physics breaks down in space - both theoretical and quantum mechanics. Take a worm hole for example.
It's an excellent video, but I just get the impression they're feeling around in the dark. Maybe such experiments will lead to the discovery of things we don't know about.
