Abstract
The main argument by proponents of Many-World interpretations of quantum mechanics is that as more and more previously disentangled degrees of freedom become entangled with the microscopic degree we measure, there is no way of telling when the measurement (in the sense of a collapse of the wave function) should occur. Here, we introduce the concept of quantum interlinking, and argue that all macroscopic objects in the universe are connected through links of mutual entanglement while the objects themselves are (for the most part) not entangled. The measurement occurs when the degree we measure becomes entangled with any macroscopic object, and hence interlinked with all of them. This picture resolves long standing paradoxes such as Schrödinger's cat and EPR.
