Yom Kippur starts in 12 days. How can it be done safely?

I am not an expert, but a Jewish friend tells me ppl pray and sing for 3h in a synagogue one evening and 10 more hours the next day.

That's a recipe for disaster.

As we know, lots of ppl confined for a long time in the same place, talking, singing, praying is the perfect breeding ground for the coronavirus.

It led to 1000s of cases early on in SK. How 75% of a choir in Washington State got infected early on.

There are dozens and dozens of outbreaks that started in churches. the massive Navajo Nation one is a good example.

So what can we do?

[3/5]
1. Do it outdoors. I am not Jewish so I don't know the meaning and importance, but I do know the risk becomes substantially higher indoors
2. Use a mask all the time
And if you can't do it outdoors:
3. Limit the # of ppl substantially
4. Don't mix ppl from different households
5. Cut the length of time dramatically
6. Ventilate heavily
7. If you can, do quick tests to everybody

Anything else I'm missing?

We can raise our population on Earth from 8 billion to 100B humans if we want to

Would we starve?
Be too crowded?
Would pollution explode?
Ecosystems collapse?

No! Don't believe alarmist degrowthers. This is why they're wrong: 🧵 Image
Degrowthers put a label to "how many humans can the Earth sustain": carrying capacity

Their estimates vary wildly
Wait, what? What a surprise, the mode of their estimates is 8B—exactly the current number of ppl on Earth

WHAT A COINCIDENCE!Image
Or they lack imagination: OMG the Earth is already on the brink. Surely not one more soul fits here!

And then they try to find out what limits we might be hitting. Their most common fears are:
1. Room
2. Food
3. Water
4. Energy
5. Pollution
6. Resources
Let's look at each:

Can desalinated water deliver a future of infinite water?
Yes!
• It's cheap
• It will get even cheaper
• Limited pollution
• Some countries already live off of it

We can transform deserts into paradise. And some countries are already on that path:🧵 Image
Crazy fact:
Over half of Israel's freshwater is desalinated from the Mediterranean!
And the vast majority of its tap water is desalinated too!
And it costs less than municipal water in a city like LA! Image
It's not the only country. Saudi Arabia is the biggest desalinator in the world. 50% of its drinking water is desalinated. It's 30% in Singapore, a majority of water in the UAE...

What if we applied this, but at scale across the world? Image

President-elect @realDonaldTrump could own the environmentalists by solving global warming on his first day in office, and do it for 0.1% of current climate investments

Here's how: sulfate injection 🧵 Image
1. GLOBAL WARMING
2024 is the 1st year we pass 1.5ºC above pre-industrial levels
This is caused by CO2
Some side-effects of this CO2 are good, but it's undeniable that the planet is warming fast, and it could create some nasty pbms Image

Should you be able to experiment on your own cancer?

This expert virologist did. It was the 3rd time her cancer appeared. It didn't bode well. So she injected viruses in her tumor and it shrunk.

But most journals didn't want to publish her results. Why? Because they're dumb 🧵
Beata Halassy got cancer in 2016, then again in 2018, and again in 2020. That looked awfully bad. She knew if she continued in the traditional route, her cancer might eventually prevail. So she decided to try what she knew about: viruses Image
Here's the theory:
1. Select a virus that is likely to attack your target cancer cells
2. Because cancer cells neutralize the immune system, they're more likely to be killed by viruses than healthy cells

Now that Starship can land, it's ready to go to Mars in 2026

Why then?
How will it go?
Why don't we need a Moon station for pit stops?
When will humans go?
🧵 Image
1. Why 2026?
As the Sun travels through space, its planets follow it
The Earth takes one year to orbit the Sun
Mars is farther away, and takes nearly two years
This means the 2 planets get close by every ~26 months

Starship is going to change humanity well beyond going to Mars: It will transform the Earth too because the cost of sending stuff to space is about to drop by 10x

A tip of this future comes from the Silk Road [1/6] Image
Why was it called Silk Road? Because silk is expensive & light

Transportation costs depend on distance and weight: The longer the distance and the heavier the goods, the more expensive transportation

So over long distances, only light & valuable goods could be sold—like silk Image
Cheaper transportation techniques like ships and railroads allowed many more goods to be traded over much longer distances

It started with tobacco, sugar, china, cotton... Eventually, things like corn & wheat

Trade exploded and the world got rich [3/6]
