To save time and dredging through pop-sci journalism for those who have some background knowledge already:<p><a href="https:&#x2F;&#x2F;journals.aps.org&#x2F;prl&#x2F;abstract&#x2F;10.1103&#x2F;PhysRevLett.119.240402" rel="nofollow">https:&#x2F;&#x2F;journals.aps.org&#x2F;prl&#x2F;abstract&#x2F;10.1103&#x2F;PhysRevLett.11...</a><p><a href="https:&#x2F;&#x2F;journals.aps.org&#x2F;prl&#x2F;abstract&#x2F;10.1103&#x2F;PhysRevLett.119.240401" rel="nofollow">https:&#x2F;&#x2F;journals.aps.org&#x2F;prl&#x2F;abstract&#x2F;10.1103&#x2F;PhysRevLett.11...</a>

I find the subject fascinating, but the main impact I got from reading this was learning how a young, curious, extraordinarily intelligent person with immense potential and who already contributed so much is murdered by human stupidity. I&#x27;m reminded of a line from Elton John&#x27;s song about John Lennon&#x27;s death, &quot;It&#x27;s funny how one insect can damage so much grain&quot; and wonder about the amount of grain destroyed by insects such as Hitler, Stalin and so many others. Don&#x27;t have much of a point to make, just some reflections about the human condition

Just a dumb layman question: can gravitons (assuming they exist) escape a black hole?

Is gravity, fundamentally quantum? I thought the jury was still out

off topic, but; before clicking the link I guess I was kinda surprised the Atlantic would get in on a story like this but then I saw that its a reprint from Quanta Magazine. Anyone know what their partnership is?

it could take a decade or more to pull it off.<p>My question why is it getting so long to get result How do software step in to help streamline research ? I can not help thinking this is steve job &#x27;next&#x27; company time in the sun
