the big bang the big bang so if I understand correctly Richard Feynman proved that antimatter is flowing through time in the opposite direction... i hear about the paradox of where all the antimatter went during the big bang. why do we observe only matter left over? if antimatter flows in the opposite direction in time, wouldn't it be flowing further into our past from the point of origin? wouldnt the two have been separated by their respective directions of time instantly?

DNA Damage Lab Using UV and Yeast DNA Damage Lab Using UV and Yeast Hello! I am exploring DNA damage by testing how UV Rays affect yeast. The procedure originally says to use the sun for the UV rays however, in case of bad weather I wanted to know if an artificial UV source such as a UV light would have the same effect? Thank you!

Phospholipids in a non-polar substance

Ask an Expert Topic Forum: Grades 9-12: Life, Earth, and Social Sciences

Phospholipids in a non-polar substance Phospholipids in a non-polar substance In class, we were recently taught that in water, phospholipids form a lipid bilayer with the polar heads touching water and the non-polar tails facing each other. In that case, if we were to put phospholipids in a non-polar substance, would the polar heads face each other and the non-polar tails face the non-polar substance? Read more
