Left-handed viruses & pathogens

01 January 1970 1 8K Report

Ebola, Nile, and Covid19 viruses have something in common with pathogenic bacteria E.Coli. Their molecular structure is left-handed in a world of DNA-ruled creatures right-handed. Think of both your hands. Even if both are composed of 4 fingers, an opposable thumb, and a palm, they are not the same and impossible to superimpose. It happens the same with molecules.Are those molecules triggering an excessive right-handed immune reaction in humans because they are left-handed?

Michael J. Benedik

I'm very confused by your question, by what criteria are saying that those viruses (or especially pathogenic E. coli) are left-handed? What is it that you are saying is right or left handed (and I do understand stereoisomers)?

Does GR require dark matter to be present to hold a galaxy together? Would First Motion be an improvement?

The information I have is that GR requires dark matter to be present to explain how masses in a galaxy are held together. In First Motion, there is not such requirement because the collective...
