Space is big, and it’s getting bigger. But where does all that new space actually come from? And is it popping into existence all around you right now? Is that why the remote control is always further away than I thought? Nearly a hundred years ago, a collection of observations and theoretical ideas came together to reveal the universe is expanding on the largest scales. The distant galaxies are all racing away from us, and interpreted through the lens of Einstein’s general theory of relativity, this only makes sense if all distances everywhere are increasing evenly. This revelation led us to the discovering of the beginning of the universe at the big bang, and lets us predict its future - it’ll probably expand forever, FYI. We know the effect of cosmic expansion on the most enormous scales, but what about the here and the now? If space  is expanding everywhere,  is it expanding inside the solar system, inside you? And what does it even mean for space to be expanding? Does that stretch
