I didn’t realise that, thanks for clarifying.

I wonder if this predicted supermassive black hole merger is rare for us - once in a lifetime, or we find out after LISA is operational that they happened frequently.

Am I right in thinking that the search area something like LISA and LIGO "see" is essentially the entire observable universe?

Could we could catch a merger from the first billion or so years of the universe?

This is insane!

Between 100 days and 3 years we will record what will be the single largest energy release we have ever recorded.

To give an idea of our records so far: our detection of black hole mergers around the 100-150 solar masses scale are just behind a couple gamma ray bursts as the single largest energy release ever.

How big are the black hole mergers around 150 solar masses and the two largest gamma ray bursts?

The energy release converted the mass of between 1-6 solar masses into energy.

With black hole mergers this energy release/conversion is in the form of gravitational waves that we then detect!

So imagine the sun, times 6, every atom, converted into that energy. That’s what we have already recorded.

This predicted one is not even in the same ballpark. Those 1-6 sun matter into energy conversions are ants compared to what’s coming.

These supermassive black holes are thousands to tens of thousands of times the mass of our sun. (Not sure if the ones in this paper are in the billion solar masses class. Yes they do exist)

This event will convert the mass of perhaps a hundred or a thousand suns worth of matter into energy in an instant. (Not sure if the paper gives any accurate predictions I’m lazy!)

On the topic of Adobe and things to look out for:

I paid for the full subscription for years as I got a lot of use out of it for many projects.

What made me quit Adobe was their iPad Pro apps.

I found myself using the iPad Pro for visual art projects more often, and I eagerly awaited Adobes eventual iPad Pro offerings.

The only file storage option in the iPad versions of Photoshop and Illustrator is Adobe cloud online with offline cache allowed on a per file basis.

Every project has mandatory upload to Adobe cloud. No way to disable.

I am comfortable having client work stored on iCloud, and sometimes will use Dropbox, both have decent enough reputation for secure storage of IP.

But Adobe? I’m sorry but any company forcing professionals to store client IP on their cloud offering by definition cannot be considered secure, who knows what data mining they do if they are willing to pull stunts like this.

On principle I found alternative apps and ditched Adobe.

Tezos is Proof of stake, decentralized and clearly has consensus, the three things the author argues cannot occur in a proof of stake system.

I did not find this post convincing especially as many proof of stake systems have been running consistently for years now and with significant transaction and economic volume.

As an example Tezos has decentralized apps such as liquidity pools, collateral based stablecoin systems, nft ecosystems, coin bridges to other networks such as Ethereum (two way) I use these smart contracts on a weekly basis and have done for a long time now.

Tezos manages several orders of magnitude more transaction throughput based on opcode count count vs Bitcoin, transactions, even complex ones cost pennies the network has not been attacked, is worth billions and Tezos energy usage is easily a million times less than Bitcoin.

The missiles are US but I was under the impression the warheads on UK tridents are UK built. No US warheads involved.

This might be a good use case for Arweave.

I think you and the op are in agreement...

Unfortunately the iPhone 11 Pro has a softer screen, I had mine accumulating permanent scratches within just a few days which surprised me as every other phone I’ve owned had no issues without a screen protector.

So iPhone 11 Pro max become the first phone I had to buy a screen protector for, really disappointing in such an expensive phone.

I think that’s just for lower orbits, I was under the impression our geosynchronous satellites will be up there for millions of years (unless future humanity cleans up the geosynchronous graveyard orbit)

According to the tweet, if a $1.00 app is refunded the customer gets back $1.00 from the developer and Apple keeps $0.30.

So each refund costs the dev more than they took in for the sale whilst Apple always pockets the 30%.

How can a refund cost the dev $1.00 if they only took $0.70 for the sale?

From memory SEC fined Musk and Tesla and Musk tried playing hardball with them and the SEC immediately doubled the fine. They were willing to start an escalation and Musk finally backed down.

Sounded to me like he was not in a strong position last time and another blatant violation is unlikely to be an easy walk in the park.

The share price has immediately moved, this is just reckless behaviour.

If it turns out this tweet about Tesla share price is legitimately from Elon Musk, yikes the SEC will eat him up for sure.

The last few tweets are nuts even for Elon Musk, I think it’s likely his account has been hacked.
