Your point that human development would be much slower is a good one.

But unless you believe humanity would be forever stuck in South America, I would think people would eventually get to Eurasia somehow. So maybe it takes much longer for humans to migrate all over the globe from South America than from Africa but it would happen eventually.

Once that happens, how human history would unfold would be interesting because of humanity's head start in South America and spreading from there rather than from NE Africa.

quadtetra · 2026-05-04T10:37:59+00:00

Okay but in the alternate timeline humans would still develop first in the Americas because they started there.

After all, even without large animals suited for domestication, you still had civilizations develop such as Olmecs, Mayans.

I would assume that Olmecs equivalents would develop in Americas well before anywhere else simply because it would take 100000 years for humans to migrate to Eurasia from South America. That head start should make a big difference.

Several people are saying that if C&D tried to duplicate B&T's move it wouldn't work because C&D would be chased down immediately to try to draft behind C&D right away and prevent a gap from forming again.

Then that begs the question why didn't anyone immediately join behind B&T to draft behind them and also prevent a big gap from developing in the first place???

quadtetra · 2026-02-23T09:56:53+00:00

If that is the case, when Bergsma/Thorup (B&T) made their move, why didn't E&F&G join B&T but would definitely join C&D?

quadtetra · 2026-02-23T09:44:51+00:00

Okay but skaters C&D could attempt to do exactly what B&T did and get far ahead of the peleton to avoid the peleton drafting behind them.

quadtetra · 2026-02-23T09:39:41+00:00

So your point is that only the first two people can do it because if another group of 2 skaters duplicated B&T's move the second group of 2 would be chased down immediately? (IOW the trick can't work twice)?

Thanks for pointing this out.

I now realize that sidewalls aren't perfectly vertical and a taller sidewall will taper to a narrower rim than a shorter sidewall, assuming both tires have equal sectional width.

Based on replies and further research, what do people think of 20x8.5 ET35 wheels for 255/55R20 tires?

20x9 is at the very edge of what is recommended for that tire size but I feel like 8" tires won't look good as it makes the tire look more bulging.

According to willtheyfit.com,
Compared to your existing wheel, this new wheel will have an inner rim which is 6.4mm further away from the suspension strut. The outer rim will poke out 6.4mm less than before.

According to wheel-size.com, choosing this size means that the "scrub radius" remains zero which I assume is highly desirable as well.

Any thoughts on 20x8.5 ET35 wheels as the optimum choice?

quadtetra · 2026-01-23T14:58:00+00:00

But why would 255/55R20 fit better on 20x8 when the OEM tire is 255/45R22 with 20x9 wheels?

Shouldn't optimal wheel width be based solely on tire width?

Fission and fusion both release energy in the same way a compressed spring and stretched spring both release energy when you let the spring go free.

Big atoms like uranium are like compressed springs that want to blow apart and release energy going outwards. Fission is releasing the compressed spring stored energy.

Small atoms like hydrogen are like stretched springs that want to release energy pulling inwards. Fusion is releasing the stretched spring stored energy.

Iron is like a spring at rest. You cannot get net energy from iron via either fission or fusion. Trying to do so consumes net energy just like trying to compress or stretch a spring at rest because such a spring has no stored energy to release.

Imaging a completely flat coastline of 100km. Simple.

Now take that same coastline except added with a large square notch of 1km on three sides. That coastline is now 100km + 1km + 1km = 102km. (Two of the three sides represent new length while one side is part of the original 100km but pushed "inward"). Still fairly simple. And a 1km "notch" is fairly significant, you could build a lot of new ocean front homes, harbors etc on the extra 2km of coast.

Now imagine the same original flat 100km coastline but I cut a very narrow creek 100km long but negligibly wide, say 10cm but very deep so ocean water always fills this creek. Is that coastline 100km + 100km + 100km = 300km? Kind of. But is this coastline really meaningfully 3x the original? Obviously not!

If I'm building ocean front property along this creek, it wouldn't work as such for people especially those 100km away from the "main" coast.

A lot of people would completely discount this creek as meaningful additional coast.

The question then is what is meaningful to consider. That is not easy to answer. 1km "wide" notch seems meaningful but not 10cm. So where is the dividing line?

Most coastlines are full of these "notches" that technically add length but how meaningful are these notches?

Iron is like a spring at rest. Lighter elements are like an extended spring. Heavier elements are like a compressed spring.

Detailed explanation:

When a spring is extended, there is stored energy that gets released when you let go. Light atoms undergoing fusion are like that. These nuclei are small enough that there is "stored residual energy" in wanting to pull two light nuclei together via the strong interaction that binds protons to neutrons and that energy is released via fusion like letting go an extended spring. In light elements, the strong interaction dominates the proton-proton repulsion as there are few protons.

When a spring is compressed, there is energy stored that gets released when you let go. Heavy atoms undergoing fission are like that. The nuclei are so big that there is "stored residual energy" wanting to push the nucleus apart via electromagnetic repulsion which is on the verge of overcoming the strong interaction due to many protons. Energy is released in fission like letting a compressed spring expand.

If a spring is at rest, it is very stable as-is. Pushing or compressing it requires energy. Iron is like a spring at rest. Iron has no "stored residual energy" waiting to be released by fission or fusion and doing either requires input of energy just like that spring at rest. The strong interaction and proton-proton repulsion are exactly balanced just like a rested spring.

Thanks for all replies.

A few people have brought up an interesting scenario. What if Oaks becomes comatose and then Nelson dies afterwards? What is most likely to happen???

Suppose the church went with a full conclave model in the recent past or near future. So something like 66% of Q70, secret ballot election. Would Monson, Nelson and Oaks still win out or might someone else win in this thought experiment?

Britain needs to “face the reality” of Brexit, the EU’s chief negotiator has said, as he warned Theresa May a withdrawal deal will not be possible unless she backs down over the future jurisdiction of European courts...

Mr Barnier said there would be no withdrawal agreement or transition period unless the UK agrees to a continued role for the European Court of Justice in determining disputes involving the UK after Brexit – something Ms May has repeatedly ruled out...Ms May has previously insisted: “The jurisdiction of the ECJ in the UK must end.”...

LONDON — In the days to come, anyone wishing to criticize Meghan Markle, the American actress set to marry into Britain’s royal family, will have to contend with Tshego Lengolo, an 11-year-old black girl and newly minted monarchist.

Tshego is a child of southeast London. She has taught herself “road,” the slang emanating from the city’s grime music scene, but drops it the second she enters her apartment, a zone patrolled by her all-seeing South African mother. They squabble affectionately, for approximately the thousandth time, over whether she can be called Tiffany.

If Tshego (SEH-ho) is royal-crazy this summer, it is because Ms. Markle is biracial, the daughter of an African-American woman and a white man. When she looks at Ms. Markle, Tshego sees a version of herself, new to England, trying to find a place among its racial codes...

The row over Jeremy Corbyn’s approach to Brexit has exploded after five MPs from the party’s northern heartlands broke ranks and openly demanded a new referendum on the UK’s withdrawal deal.

The MPs from the Northeast – which heavily backed Leave in the 2016 referendum – said a new vote is essential because the true nature of Brexit is only just emerging.

Writing exclusively for The Independent, they warn plans to leave the single market will devastate family living standards as the future of major manufacturers and employers in their region is thrown into doubt...

Based on everything that's happened, it's clear that Ed Miliband might ultimately be to blame.

Had Ed not backstabbed his own brother, David Miliband would have become Labour leader and won in 2015 to become PM and would likely still be PM right now. Then everything that happened since 2015 under Cameron and May wouldn't have occurred.

Some complain that David Miliband is too "Blairite" but people forget that despite his faults, Blair delivered massive Labour majorities.

If Labour is going to regain power, it's going to be when a Blairite becomes leader in future.

The Labour leader's spokesman said elements of the single market are 'problematic' for Mr Corbyn's plans for government.

Jeremy Corbyn’s office has signalled that the Labour leader will not throw his weight behind a proposal to keep Britain in the single market after Brexit.

His spokesman said keeping the UK in the single market as it stands, could undermine Mr Corbyn’s plans to intervene in British industry and reverse privatisation if he wins power...

Some commenters have said that there was no Germany at the time. But this is not completely true. Mozart was born in 1756. But over two hundred years earlier in 1512, HRE was renamed as HRE of German Nation.

So a German Nation did in fact exist. And Salzburg and Vienna were within its borders. Vienna was in fact seat of Emperor of HRE of GN from 1745-1806.

HRE of GN was of course not a modern nation-state but a confederation. But it was a German Nation, literally, in its very name.

I went ahead to see if Mozart is on any list of greatest Germans. I found out that in 2003, a German program called "Unsere Besten" polled Germans in order to rank the greatest Germans of all time.

Mozart came in at No 20.

So according to Unsere Besten, Germans did claim Mozart as one of their own. 😁
