I think that agriculture and textiles are generally among the first recognized technology. I've never seen them overlooked, quite the opposite.

I agree that my usage of the term "now" was incorrect. "Now" really isn't defined well when the concept of simultaneous events is not valid. I also used reference frame when referring to distant objects, for the sim

In fact I personally know two women whose babies were burned to death by Gazans on October 7th. The fact that you people laugh at that solidifies our resolve to protect ourselves from you.

No, I clearly state that Israel's actions do not constitute a Holocaust because though that term is ill-defined, every one of the definitions either concludes that Israel is not conducting a Holocaust, or that half a dozen Holocausts h

No, actually, the photons did not travel over a period of time. Photons travel at C, and thus experience no time in their reference frame. As for _our_ reference frame, I've explained in other comments but a debate has developed betwee

I may have misunderstood Hawking, but my Physics grades suggest that I do understand the principles. I tried to explain within the confines of an HN comment so that GGP could understand. Any answer that fits in this box will be incomplete.

You are getting downvotes, but you are correct. People are voting by intuition, not by physics. Relativity is not intuitive.

> So a hypothetical photon from the big bang (era?) gets observed now means the big bang is happening now? Yes. More specifically, the big bang would be happening now, at the location from where we perceive that photon. Hey, this

Light is not a particle, nor is it a wave. However, under some circumstances it does behave like a particle - we even have a name for that (photon). However for purposes of this type of discussion - how it travels long distances - we need t

The link is just smaller, and I think the text is now something to the effect of "Can't Download App" or similar.

While the conclusions of the observation are interesting, what really stood out to me was the observations themselves. That black hole is 20 million light years away, in another galaxy! And we have multiple high enough resolution observatio

That's not how things work when you are participating in hostilities in an active war zone. What a ridiculous statement to make.

Parent comment is implying that an ally (Israel) is performing a holocaust. In fact, there have been a good dozen genocides in the past century which I would agree fit the term, but not the conflict that Israel is involved with. The anti-Is

To other readers: Parent is suggesting that the 6000 Gazans who breached the Israeli border on October 7th 2023 and killed 1200 people, mutilated bodies, beheaded humans and dogs alike, raped women, and took over 250 hostages including infa

Hamas claims that the journalists are Hamas, not Israel. And I'm not declaring any journalist "good" or "bad". I'm stating that a Hamas member is a valid target. Him moonlighting as a journalist does not change

Israel never set out to exterminate, Israel set out to get her hostages back - including babies under a year old. You know who did set out to exterminate? Hamas, who in their very own charter state their intention to eradicate the Jews: ht

Your Holocaust inversion is not only morally wrong, it is also factually incorrect.

I was waiting to see how long it took for someone to "make this about Palestine" - their strategy is to inundate all discussion with the topic. Over half the journalists in the Gaza Strip are affiliated with Hamas. Many of them in

This is probably one of the most important comments on HN, seriously. A concise summary that once we get the model right, the emergent behaviour matches observations. Very reminiscent of the Casimir effect experiments.

Why Libreoffice? Does your diary contain advanced formatting, tables, images, or other involved content? Or just for the encryption? I ask because I also keep a diary and have refined how I store it and secure it, over 25+ years. Only recen

They have absolutely zero regard for system resources. I understand why, but such things were once considered unfeasible - and very recently were also considered undesirable. I still use a laptop with a 100 GiB hard drive - only 80 of which
