Starlink is leaking into radio astronomy bands, they initially said there wouldn't be a problem, but there was. They've later stated it would addressed in Gen-2 - it got worse.

> Starlink is not violating current regulations, so is doing nothing wrong.

Might be time to make global regulations on spectrum usage in space? That could take a while.

There are many past examples of companies "not violating current regulations" despite leaking toxins and other now recognised violations of the commons.

Again, Christians have been just as appalling as any other religion.

They've killed, enslaved, done their best to eliminate cultures, railed against miscegenation, etc.

Not sure why you're working so hard to pretend o/wise.

There are more people now than at any point in time in history.

Meanwhile, in history, religions enslaved people.

Returning to the point you keep dodging, that includes Christians.

Think of it less as a comms system with a small increase in bandwidth, and more as a radar system with a larger increase in resolution.

Be fair now, the Catholic Church hasn't always and consistently been a backward medieval deathcult - there have been periods of non Crusading, non Inquisition, not slaughtering Cathars, not trading in babies, etc.

The Vatican is a theocratic state, Catholic churches, schools, etc are effective theocracies.

There's a long list of questionable behaviour, eg. enslavement for Jesus: https://en.wikipedia.org/wiki/1838_Jesuit_slave_sale

The subject wasn't the creation of technology, it was the propensity of theocracies to beat the native out of natives.

Professional radio astronomy - SKA et al.

eg: Scientists analyze 76 million radio telescope images, find Starlink satellite interference 'where no signals are supposed to be present' (2025)

and the topic is Starlink (and other sat constellations) and their impact on the sky (visible and non visible).

Yes, they do post about it.

Yes they do talk about working to avoid causing interference.

That's been ongoing since before the first Starlink went up and has been ongoing as later generations haven't improved.

Second-Generation Starlink Satellites Leak 30 Times More Radio Interference, Threatening Astronomical Observations https://www.astron.nl/starlink-satellites/

  Observations with the LOFAR (Low Frequency Array) radio telescope last year showed that first generation Starlink satellites emit unintended radio waves that can hinder astronomical observations. New observations with the LOFAR radio telescope, the biggest radio telescope on Earth observing at low frequencies, have shown that the second generation ’V2-mini’ Starlink satellites emit up to 32 times brighter unintended radio waves than satellites from the previous generation, potentially blinding radio telescopes and crippling vital research of the Universe.
Still, at least they are talking about maybe doing something. Eventually. Perhaps.

and several other papers over the past half decade.

It's old news that they leak, and old news that F-all gets done about it.

Back to you.

You forgot about the radio spectrum pollution which affects the night and day sky right now .. and for the foreseeable future given the lack of progress in addressing that leakage.

Sucks for regular astronomy then, where long exposures are the norm.

Equally sucks for radio astronomy where the bloody things leak into spectrums they (Starlink) pinky promised to keep clean. And successive generations have worsened the problem, again despite promises to improve.

Kind of moot given Japan surrendered.

Had they not, the carpet bombings would have continued - not just the fire bombing of Tokyo, another 71 cities had also been bombed flat. With H&N that made a total of 74 cities down and a list of targets for future bombing still ready to work through.

FWiW the HE+incendiaries bombings used more planes but were cheaper overall than (at that time) atomic weapons - and (at that time) caused much the same amount of damage, injury, and death.

Just cancer might be the equivalence.

Smoking itself cause damage and disease that isn't limited to just cancer though.

Thanks for the response, it's been awhile since I used an ambulance. I've got to say, I was willing to believe, what with free Qld buses and all that jazz, but alas like WA it's "qualified":

  There's no cost for ambulance treatment and transport for Queensland residents. This includes treatment and transport that takes place in other parts of Australia.
and

  If you don’t live in Queensland, you’ll be charged for ambulance treatment and transport. If you have ambulance cover in another state it may cover the cost for you.

> the Gregorian date with year 1 as the (wrongly dated?) birthyear of Jesus Christ is the standard for most domains in international communication.

Save for those that care about missing days and months.

As long as cross country events prior to ~1756 aren't being discussed, things get messy and non uniform fast.

Also, there are Gregorian adjacent calendar variants with a Year 0

> some future astronomer will be translating timestamps between GPS time and UTC, entirely aware of leap seconds and atomic time and whatnot, just to make sense of 21st century observations.

A future where the spin of the earth still isn't a uniform metronome - a future with the same issue that exists today (and last century).

> their woes will pale in comparison with those of the poor soul who has to add support

Much of this support has _already_ been added - SKA data networks, for example, have to account for timing issue caused by receivers on one side of planet turning toward a source Vs those on the other side turning away - and reconcile that with past data from the other side of the orbit when the planet was moving toward Vs now when it moves away.

Yeah, nah - that "we" doesn't cover all the other calendars also in use.

  The Julian period is a chronological interval of 7980 years, derived from three multi-year cycles: the indiction, solar, and lunar cycles. The last year that was simultaneously the beginning of all three cycles was 4713 BC (−4712), so that is year 1 of the current Julian period, making AD 2026 year 6739 of that Period.
