Push it, and unlike every physical object in the world we know, it doesn’t accelerate in the direction it was pushed. It accelerates backwards.
So, I suppose Marxists are now referring to their political movement as a religion. It follows that their motivational gathering intended to disseminate the newest negative narratives are ‘Negativity, or Negative Masses’.....

Very cool. It amazes me how much humans know. But what really amazes me, is how much we don't.
Hmmmm. Wish we could discuss evolution here but it would too quickly violate rules.
I'm a scientist, though not a physicist so anyone feel free to educate me.
1. Electrons ARE leptons. One of several sub-types.
2. Upgrading the Hubble has never allowed it to see farther. Roughly for 1/3 of the first million years after the Big Bang the universe was an opaque plasma that allowed no light transmission. We can see back that far. There is the absolute limit. Upgrading the Hubble (remedying its defect, actually) increased its resolving ability. It sees more detail but not farther.
3. Our empirical observations best approximations:
a.For roughly 10,200,000,000 years there was no earth.
b. Then the earth formed from the aggregated ejecta of a dead star where the calcium in your bones was fused from lighter elements. Scant doubt about that.
c. For around 1,000,000,000 the earth was utterly sterile. That's a best guess.
d. For the next 3,000,000,000 years the only life was single celled organisms reproducing and evolving complexity existing solely within the oceans.
e. Multicellular life has only been around on our planet for about 12% of the time that the earth has been around but that brief 600 millions years is tough to comprehend in my mind.
f. At one moment in time, around 1/2 billion years ago, one of those single celled creatures was my ancestor.
g. I find that fact incredibly cool to accept.
There is no plausibly verifiable competing hypothesis.
Oh, last thought. One very well verifiable today:
A very few million years ago two of the 24 pairs of chromosomes in some hominid ancestor of ours fused to become chromosome #2 and henceforth begat our unique 23 pair genome, unique amongst our great ape progenitors and cousins.
You and I have telomeres in the center of our chromosome #2 documenting this momentous evolutionary event when our lineage too the path to modern homo sapiens.
All the other great apes have the original 24 pairs.
Easily demonstrable and pretty unequivocal that we share an ancestor. And, yes, it's harder to perceive, realize and ultimately accept that a phytoplankton was an ancestor.
Yet again, there is no plausibly verifiable competing hypothesis.
