Dialog / Not so dark with Alena Tensor: Math framework could explain dark matter without invisible particles

Alena Tensor is a relatively new mathematical approach that allows for arbitrary curving and straightening of analyzed spacetimes. As it turns out, generalizing this model to all known fields and fully describing matter, ...
