A US tech startup is proposing to use mirrors in space to power solar farms on Earth at night. Is this even feasible? And what are the light pollution dangers?

Myself and @mattkenworthy.bsky.social have crunched the numbers for The Conversation.

A US startup plans to deliver ‘sunlight on demand’ after dark. Can it work – and would we want it to?
Satellites beaming sunlight down to Earth sound like science fiction – and they have astronomers very worried.

Judge Biery signed the order with a photo of Liam and two bible verses: The first is "But Jesus said, Suffer little children, and forbid them not, to come unto me: for of such is the kingdom of heaven." The second is simply "Jesus wept."

Astonishing thing for a judge to do.

1. Data centres in space ➡️ Lol 🤭

2. FCC is not a global authority — it approves spectrum usage

3. Exhibit no. 489 of one company caring for nothing more than its profit ambitions

4. Language in the filing is so try hard sci-fi. More lolz

5. We need a UNOOSA-level authority ASAP

6. Grifting.

The Pew poll, conducted Jan. 20-26, found majorities of all religious groups except white evangelicals disapprove of Trump. White evangelicals give him a net 69% approval, which is about the same as in 2019.

This is getting ratioed hard, including by physicists.
Maths and physics are objective and humanities is subjective.

Some people are questioning whether this is AI. One way to be certain is to geolocate the video, as AI still struggles to accurately recreate really world locations with enough fidelity to be successfully geolocated. The first question is what's the best information about where this was filmed?
News Movement posted this video of Alex Pretti on Jan 13, showing him spitting at ICE agents and kicking their taillight.

Now conservatives are suggesting this changes things.

That would mean they are suggesting he deserved to be target of an extrajudicial execution.

The video changes nothing.

Think about it like this. This ICE agent was on camera and unmasked — fulfilling one of three "demands" Democratic leader Chuck Schumer just issued in order to agree to save Republicans and give DHS even more money.

And he was still threatening to kill someone.
