This also means that there could be hidden curvatures of space-time or gravitational fields, which could explain a fundamental issue in physics: the hierarchy problem. There are several ongoing ...

Researchers have created a new 3D model of human embryonic tissue that promises to shed light on critical components of development -- including processes that go awry during pregnancy complications.

Theoretically, it’s impossible for us to perceive a 4D creature. That is, unless it broke into our three-dimensional reality.

Arguably, all of scientific inquiry in modern times begins with some sort of model. A model takes different parameters you are studying and uses them to make some claim about how our world works. It ...
