Surely the antigen tests detect the presence of antibodies, which the vaccines stimulate the immune system to produce? I can see that the PCR test will do a better analysis though.
For someone who has been vaccinated against Covid-19, will a subsequent Covid test show up as positve? If so, how is it possible to have a negative test after being vaccinated?
As I understand it, a virus like HIV for example cannot survive more than a few degrees below normal body temperature. Is it possible, therefore, to reduce the whole body core temperature, under controlled conditions, to well below the virus survival threshold temperature, thereby killing the virus?
Why is light viewed as both wave energy and particle motion, whereas other forms of electromagnetic radiation is only seen as waves? Light is just a small part of the spectrum, so, surely all electromagnetic radiation should be viewed in the same way.
I recently saw a documentary on TV in which Stephen Hawking stated that the universe was 600 lightyears in diameter, 10 minutes after the Big Bang. How can this possibly be true? - the particles and matter making up the outer limits will have had to have traveled at many times the speed of light...
