We will consider the torsional completion of gravity for a background filled with Dirac matter fields, studying what happens when fermionic non-minimal coupling is taken into account: we will show that, although non-minimal couplings are usually disregarded because of their ill-defined behaviour in ultraviolet regimes, this is due to the fact that torsion is commonly neglected, whereas when torsion is not left aside, even non-minimal couplings behave properly. In detail, we will see that the presence of non-minimal coupling may evade the cosmological singularity and that in some type of non-minimally coupled model parity-oddness might be present even in the gravitational sector. In the course of the paper, we shall consider a specific interaction as prototype to study this fermionic non-minimal coupling, but we will try to present results that do not depend on the actual structure of the non-minimal couplings by investigating alternative types of interaction.
Anonymous asked: Is dairy actually bad for you? And also I'm thinking of becoming vegan but how would I ensure that I get all the vitamins I need?
yeah it is unless you’re a calf (in which case props to you for typing this ask #respect):
- lactose intolerance causing negative effects following dairy consumption
- high saturated fat content
- possible increased risk of ovarian cancer
- possible increased risk of prostate cancer
- milk is the biggest dietary cause of osteoporosis as it depletes the reserve of bone making cells in the body.
you can read more about these on the following links:

as for vitamins; eat food - it contains everything you need. more specifically, see my nutrient list: http://vegan-hippie.tumblr.com/vegannutrition
