Cosmic simulations that once needed supercomputers now run on a laptop
If you think a galaxy is big, compare it to the size of the Universe: it's just a tiny dot which, together with a huge number of other tiny dots, forms clusters that aggregate into superclusters, which in turn weave into filaments threaded with voids -- an immense 3D skeleton of our Universe. If that gives you vertigo and you're wondering how one can understand or even "see" something so vast, the answer is: it isn't easy. Scientists combine the physics of the Universe with data from astronomic
