Part 3/9:
The authors of the recent paper challenge the conventional wisdom by asserting that we have been misinterpreting gravity. Instead of assuming spacetime is curved, they propose that space is flat—unchanging in its geometry—and introduce four new bosons, one for each direction of space and time. While this approach may seem peculiar—suggesting four distinct carriers for a single interaction—the concept is that these bosons collectively produce the effects typically ascribed to gravity.
