I love stories like this. A subtle reminder how inconsequential our actions are on this planet in the grand, unplanned scheme. I look forward to reading HN with my breakfast each morning then going to a job that helps me raise a family and have fun on the weekends. I read stories of war, corruption, sadistic leaders, and great suffering. I've learned to appreciate the joys of life and have come to terms that we are not here for a long time - just for a good time.

I don't find that to be useful at all.
Yes of course, all the suffering on Earth is nothing but a footnote in 0.000000001 font size as far as the universe is concerned.
But that's irrelevant. We live on Earth, so what happens here is actually 100% of what matters. Everything else is inconsequential.

Things can be meaningless on a cosmic timescale and still matter a great deal on a human one. Most of us will never influence the universe, but we'll influence our families, friends, coworkers and even future generations, that's enough...

What It’s Like Being Married to Neil deGrasse Tyson - Key & Peele
I'm not a religious person but this seems relevant to your comment;
> So I commended the enjoyment of life, because there is nothing better for a man under the sun than to eat and drink and be merry.
As someone with autism and ADHD; I have spent my life trying to understand better ways to do things, optimisations, doing things "right" or "better" or "faster", and trying to come to terms with others who don't really give a shit about any of it.
The conclusion I arrived at is that the snapshot of time I get in this form is best spent enjoying what this form has to offer, nothing more.
- My sausage'y shaped fingers can't manipulate time or gravity; but they can tickle my children and make them laugh.
- My heart can't fix anything; but it can help me to understand others suffering and guide my actions.
- My eyes can't see the whole electromagnetic spectrum; but they can appreciate a beautiful vista and fill me with wonder.
When TFA mentions that a star just ate a planet, I remember just how small and unimportant I am outside a tiny speck of the world; and rejoice that I'm not responsible for anything super important outside that little speck. \o/

Some of the proceeds spent on having a good time will go towards reducing misery and suffering elsewhere.
I see no malice in the decision to make peace with the fact that no mere mortal is capable of putting a dent into the level of suffering around the world as a whole.
Living one’s life reasonably and not being a burden is remarkably beneficial to society. At the very least, it’s one less unhappy and broke individual.

>> Just don’t think about all the suffering you or I could ease with the money we spend on a “good time.”
Look man. I am not responsible for any random person or creature that suffers in this world.
Lamentations like this ("ease all the suffering") originate in a primate brain that hasn't yet processed that we're no longer a tribe of 100 but there's 10 billion people in this world.
Objectively you don't have resources to help more than a few people. And morally, you aren't obligated either.
And btw, I actually do help a person in need, every month with a substantial amount of money. Unlike the occasional act of kindness, helping a complete stranger on a recurring basis is a much harder nut to swallow. Makes you progress really quickly from superficial platitudes like the one you said to the hard, cold reality of the fact that you're losing resources and resources are finite. And that on top of half my income that the state grabs and mostly hands out as welfare anyway. So don't tell me I'm not paying to ease suffering, want or not, I pay through my teeth.

One of the first gravitational wave detections by LIGO was I think the merger of two black holes or maybe a black hole and a neutron star. It was over a billion light years away I think but was so energetic that it conveted approximately 5 Solar masses into energy in about one second. That's ~10^48 Joules. In 1 second that is ~10^48 Watts.
For comparison, the Milky Way has an estimate of 5x10^36 Watts so we're talking about the energy output, very briefly, of roughly a trillion Milky Way galaxies.
The other that gets me is amgnetars. These are neutron stars with an insane magnetic field. The strongest detected exceeds 1 billion Tesla, making is 30 trillion times stronger than Earth's magnetic field. Get too close and it would flatten atoms and ultimately break molecular bonds and rip electrons out of your body. Google seems to think that happens at ~1000km, which is pretty close to get to a neutron star but still, that's a magnetic field.
These things are quite rare and quite unstable. If you think about it, they must have a lot of protons to generate a field so strong, which means that the gravity is overcoming the strong nuclear force but also the electric repulsion.

> If you think about it, they must have a lot of protons to generate a field so strong
Not necessarily. Neutrons have a magnetic moment. As I understand it, there is a magnetohydrodynamic model of how a magnetar's field gets generated, which would require protons, but it's not the only model and we don't have enough data to be able to rule out other models.
robocat 10 hours ago [-]
Aside: Carbon-13 has one more neutron than Carbon-12, so the unpaired neutron gives it a magnetic moment which is what is used for C13 Nuclear Magnetic Resonance (NMR) spectroscopy.
There is a pretty significant chance that ours will be a starfaring civilization and that our children will reshape the very heavens.

Very doubtful when you really dig into what is involved. We probably will never make it out of the solar system. To another star is a pipe dream. We will wreck our planet soon enough and the likely outcome is our species will go extinct. This will probably happen in the next few thousand years or sooner.
Bender 18 hours ago [-]
I think the planet will do just fine without us but we will likely hit one of many great filters long before we colonize anything outside of Earth. The list of dumb things we do as a civilization are too long to list on HN. I am honestly very surprised we still exist and can still reproduce.

Without new physics that isn’t even remotely visible on the horizon and that utterly contradicts most of what we believe to be true, this isn’t going to happen. Robotic AI probes sent to other star systems to send back telemetry? Sure, fine. Flesh bags sent to self-replicate on terraformed worlds out in the stars? Not a whisper of a microscopic chance.

@WalterBright, I've always preferred the idea that to explore the stars the only chance we have at doing so is by bio-growing humans (cloned?), and somehow uploading and downloading a current humans consciousness into the form.
basically 'seeding the universe' since we would just start sending little seeds of human life everywhere. :-)

I don't like that our culture has developed statements like this.
Every single action you make on planet Earth is more consequential and impactful than the countless parsecs of worthless unobtainable space dust that astrophysicists and science promoters like to glaze over.
Space is nothing compared to the unfathomable amount of synaptic connections in your brain, or the impact you can have on someone's life by hugging them.

You can think they are old and pointless, but that's you just brushing off the fact that the universe is much much older than however old you think these ideas are. The entirety of the human species from its beginning to its eventual ending is merely a blip of time for the universe.
You can argue that makes it that much more special, but so what? To the universe, there very well could have been numerous other specials that have come and gone.
Being unable to accept that is pointless.

The star is also pretty insignificant compared to the whole universe to be honest. Almost everything is at that scale.
And I mean okay, alien intelligence life must be very smart and not contact us because we are so evil and petty and self involved etc. And every single living species we encounter is also the same. Why are we grandstanding these aliens? They are likley sipping coffee in their corner of universe and wondering man why do we keep doing all this nonsense when we are so insignificant etc. That is far more likely to me than aliens who know we exist but willingly stay away because we are humans.

It happened sometime between whenever we observed it and 2600 years ago. It's equally valid to say that light travels from there to here instantly (but takes twice as long on the outbound trip) or the reverse. Taking the average is just a convention.
Hence why the articles title - which is based on when the light cone of the event reaches us - is actually the better way to think about it. At least there's no "depends how you feel like defining the speed of light today" in it.
