What Is A Rotating Detonation Engine - And Why Are They Better Than Regular Engines

What if Singularities DO NOT Exist?

Isn't that complete rubbish?

The singularity is an anomaly whereby we hit the limits of our mathematics and what we calculate would be at that position in spacetime becomes undefined.

I'm not watching the youtube - but I've seen several clickbait articles pop up around this and it seems nonsense - based on a complete misunderstanding of what a singularity "is", exploiting a laymen's idea of what one is.

Main point is to say it doesn't "exist" is nonsensical. That means the person was able to solve the equations in such a way as to get an answer for the inputs that produce the singularity.

Have they done that?

I mean...

If you reckon Roy Kerr might completely misunderstand what a singularity is after what he's achieved...

An appeal to authority as a way to undermine and dismiss.
How lame, can't say I'm surprised though.
How about some stimulating intellectual discussion instead - like actually addressing the subject matter.

Your approach to such a discussion is not very... inviting.

But even if it were, I have no capacity to argue general relativity to this degree.

I do know just enough however to recognise that anything Roy Kerr is publishing is going to be robust, when it comes to the subject of black holes.

Ok, took me five seconds of looking into Roy to see I was right.
The articles are clickbaity and misrepresentative.
Roy agrees with what I said - he thinks singularities don't PHYSICALLY exist.
Ergo; they are a mathematical limit.

You could have just said that instead of being all defensive and snarky.
FWIW my original reply was not uninviting. That you viewed it that way is the same reason for the lack of surprise in my prior comment.
Intimates you spend too much time on social media IMO. Defensive point scoring mode.

Whoever you're having an argument with, it's not me?

What I did was share a video on some cool science involving a cool kiwi, and responding incredulously to the suggestion that Roy's work was "rubbish".

You've clearly got something in mind, but I'm not following it.

I didn't call Roy's work rubbish.
I outlined exactly what I called rubbish, and it was specifically to do with what was presented as quote - I straight up said I didn't watch the video.

Turns out Roy backs me up, and what is rubbish is the presentation of his findings inaccurately - in this case specifically by what you quoted.

I was asking some thought provoking -QUESTIONS- which I thought might be right up your alley.

Instead of engaging them you got all defensive immediately.

Seriously dude.
Get off the internet for a while.

That was just the intro to the video.

If you knew who Roy Kerr was before you went off on your rant, you probably would have caught that there was more to it.

Now that you've caught up, do you get how absurd it is to suggest that Roy Kerr's work might be "based on a complete misunderstanding of what a singularity 'is'"?

No not at all actually, because I don' t treat science tribally.

I don't care who published something because science is about the data not the source - so no, appeals to authority do not do it for me, and conversely I do not feel aggrieved when someone appears to say something that might contradict someone I hold in esteem - because that is trust me bro science, and not how it should be.

If I were you I would work to look at the substance of discourse and not look for reasons to emotionally charge it like that.

I think what I said was completely valid given what was presented - but I wasn't sure which is why I asked. It actually -WAS- an invitation for you to correct my assumption since it was based only on existing data and reason.

So let me try to reply to my original message on your behalf:

It's not tribal to think that the guy who came up with the exact solution to a rotating black hole might have some sense of what a singularity is. Someone who has enjoyed a long career of successful academia.

And if you were still doubt, you could have watched the video!

Or found out what the actual body of work was, instead of guessing, only to find out when you do "oh, it's not the absurd thing I imagined after all".

I watched the video going "wow, that's a cool swirly! And he's from New Zealand, wooow."

You've given me a lot of unsolicited advice just now. Might I suggest you consider it for yourself?

Ok lightspeed.
You win the internet. You get all the points.

Sorry for being excited to share your excitement and engage you on the topic.

Thanks for posting that video, I watched it and enjoyed it. It was great to understand that Kerr is challenging the currently held expectation that a singularity must exist. He's not saying they must not exist, but putting into question the conclusions people are drawing from the current understanding of the mechanics.

indigo1, I don't know what shaped carrot was up your butt when you were posting above, but it wasn't helpful, sure as heck wasn't an invitation for a constructive and meaningful discussion, and it wasn't defensive of LS to question why you're calling it rubbish and lame, after not even watching the video in question.

Will it go once around then target Perth? Pine Gap?

Place your bets!

Wow! I got up at 12:20 but the live stream was postponed every 10-15 minutes until they got the all-clear (Shrimp boats in the Gulf? I blame Forrest...)

Nice clean countdown, and an excellent launch. Hot staging worked just like a bought one, and I managed to grab a nice screen grab for my wallpaper of the booster pointing the other way as Starship keeps on trucking.

Booster seemed to be wobbling a bit - grid fins were flipping around like mad things, so I suspect they couldn't get it stable enough to make the landing burn effective, and it hit the Gulf with a bit of grunt. Maybe worth a bit more testing in that area before they target the tower catch - wouldn't want to miss and take out the launch complex!

Starship made it to orbit, 200+ kms up, and hooning around at 26000km/h, opened and closed the door for future Starlink deploys, and apparently ran the routine to simulate transferring fuel in flight (not sure if that was the mating process or just proving they can pump Lox and Methane between the header tanks and the main ones on zero-G. They skipped the attempt to do an engine re-light in flight - wonder if that related to the fuel shuffle?

Anyway, really cool pics of it lining itself up to splash down, and the plasma was awesome - Starlink did what it could to relay the hi-res pics up until the blackout, and then the ship was lost - first test of the tiles, so perhaps some learnings there.

All data is good data!

The CIA Scientist Who Built “UFOs”

This belongs on the periphery of the "science" thread, but it's an interesting watch about what we might call UFO technology - the potentially classified/top secret aeronautic tech (anti-gravity).

There's a lot of material I've not heard before - and enough science-y words that make you consider what the technologies are about. It focuses on the work of Townsend Brown, so if you know his work, you probably know this documentary already, but if not, you might like it.

Voyager 1 has been sending a stream of garbled nonsense since November. Now NASA engineers have identified the fault and found a potential workaround.

Also, nature wtf

Software updates from 20+ billion kms away. Amazing.

I can't get my ahead around it. Not just what today's JPL nerds have accomplished - what their predecessors did in the early 1970s. Gods.

Same - hard enough to get Patch Tuesday updates to a PC in Milford Sound down a soggy ADSL line. Doing something at dialup speed that relies on a stable and fail-safe architecture that allows relocating apps within RAM banks on the fly...

So much awesome reading the JPL approach to fixing this...wish this fix it no matter what happened down here on Earth more.

Are you apes getting this Aurora, holy shit!!

Didn't even get any change in sky colour in Wellington, let alone pretty patterns - very disappointed.

Yeah apparently there was, some people on FB were positing pics from Tawa where I am, but I sure as hell didn't see any colours either :(

Well at least we know a major solar storm isn't enough to take out the world.

I was losing my shit last night, aurora is a bucket list item for me. Never experienced it before, and last night I just stepped out my front door and boom right in my face. Looking south from an Adelaide suburb at lat -35.15452 and it was green and pink and rippling just like some CG movie shit. Still tripping today.

iPhone snap from my driveway looking south (Crux in the middle). No colour or lighting tweaks at all, literally just "hold phone up press button".
