+:07:16 From Bob Primak to Everyone:
+	For travel backward in time, has anyone solved the paradox of conservation of energy and mass?
+:12:12 From Bob Primak to Everyone:
+	As an absolute physical constant, the speed of light recently has been questioned. Over long times and distances, some theorists seem to think light may be slowing down.
+:19:43 From Bob Primak to Everyone:
+	Chicken and egg -- the first chicken did not come from a chicken egg -- it came from a dinosaur egg!
+:20:05 From Bob Primak to Everyone:
+	(Not chickens specifically, but birds, generally.
+:27:19 From Jerome Slate to Everyone:
+	To know which came first, the chicken or the egg, order both from Amazon.  You will soon know which came first.
+:31:30 From Stan Rose to Everyone:
+	Interesting that these are all ideas in the Netflix series, 3 Body Problem!
+:33:56 From Bob Primak to Everyone:
+	I ordered a chicken and an egg from Amazon. The chicken was at Whole Foods before I ordered it. (It was already in my cart.) What does this result prove?
+:39:32 From Dan Silber to Everyone:
+	I have long agreed with Bob - eggs came into existence before chickens.
+:43:24 From Adam Broun to Everyone:
+	https://theoreticalminimum.com/courses/general-relativity/2012/fall
+	All the courses in this series are terrific if you want to go  that deep
+:55:58 From Judy & Mike Alexander to Everyone:
+	Eggs must be fertilized before there are chickens.  "Chicken vs. egg" is incomplete.
+:57:02 From Bob Primak to Everyone:
+	We should be careful about eliminating the genes responsible for allergies. There are some scientists who think allergies are part of our very complex immune systems. Change one part of this system, and unpredictable effects can happen elsewhere in the immune system.
+:57:09 From Barry Kort to Everyone:
+	Brand new 37-minute video from Veritasium on black holes, white holes, wormholes and parallel universes, entitled, “Something Strange Happens When You Follow Einstein's Math” ~ https://youtu.be/6akmv1bsz1M
+:59:40 From Steve Isenberg to Everyone:
+	Veritasium has good presentations, we’ve seen some in the past.  I’ll put this on the Potentials list, maybe we can show it in a potpourri.
+:00:43 From Barry Kort to Everyone:
+	Derek Muller of Veritasium is a world-class science educator and explorer on YouTube.
+:01:28 From Bob Primak to Everyone:
+	"Designer Genes" could have ethical and population health consequences. Diversity has been one key to genetic evolution. This process is necessary when, not if the Earth's environment changes radically in the future. (No implication of human causality in these changes is needed to see this issue.)
+:05:14 From Bob Primak to Everyone:
+	Ack!! Did they just refer to human genetics as a "hard drive??
