Colliding muons at a very high energy offers unprecedented opportunities to observe the tiniest building blocks of the Universe and study the quantum fabric of space and time. A 10 TeV muon collider could produce 10 million Higgs bosons and allow us to measure whether the Higgs boson has any inner structure with great precision, thereby providing insights into potentially the most exotic quantum criticality in nature. In addition, small quantum effects from electroweak interactions become significantly enhanced at 10 TeV, giving rise to previously unseen phenomena such as quantum entanglement of the colliding muons with electroweak gauge bosons and turning a muon collider into a weak-boson collider simultaneously. Similar quantum effects may also allow us to observe otherwise invisible neutrinos at a particle collider through final state radiation. These considerations suggest that, at 10 TeV, the electroweak sector of Standard Model exhibits several rich and novel phenomena not present at lower energies. Together with the possibility  to explore the last vestiges of a thermal WIMP dark matter, a 10 TeV muon collider could be the most powerful microscope into some of the deepest mysteries of the Universe.
