I wormhole, noti anche come ponti di Einstein-Rosen, sono teorizzati come tunnel che collegano due punti distanti nello spazio-tempo, permettendo un passaggio rapido tra essi. La spiegazione di come funziona un wormhole si basa sulla relatività generale di Einstein. Secondo alcuni documentari, i wormhole potrebbero teoricamente esistere e essere usati come macchine del tempo. Per costruire un wormhole stabile, sarebbe necessaria materia esotica con energia negativa, che impedirebbe al tunnel di collassare. Nei film come "Interstellar", i wormhole vengono rappresentati come passaggi praticabili per viaggi interstellari e temporali. Il concetto di wormhole come macchina del tempo implica che, manipolando uno degli ingressi con velocità relativistiche o posizionandolo in un forte campo gravitazionale, si potrebbe creare uno sfasamento temporale tra le due estremità. Questo permetterebbe di viaggiare nel tempo entrando in una estremità e uscendo nell'altra in un'epoca diversa. Tuttavia, sebbene l'idea sia affascinante, non esistono attualmente prove che i wormhole esistano nella realtà. Inoltre, costruire un wormhole con le tecnologie attuali è oltre le nostre capacità. La possibilità di viaggiare nel tempo attraverso i wormhole rimane quindi un affascinante tema di ricerca teorica e speculazione scientifica. FONTI • De-Chang Dai and Dejan Stojkovic.

En nuestra centésimo segunda entrega os proponemos una selección de novelas que abordan el tema del "primer contacto" con otra civilización extraterrestre en un futuro en el que la humanidad surque las estrellas: - Introducción (0:07) - "Primer Contacto" de Murray Leinster. 1945. (0:17) - "Misión de Gravedad" de Hal Clement. 1954). (0:41) - "El Invencible" fr Stanislaw Lem. 1964. (1:25) - "La paja en el ojo de Dios" de Larry Niven y Jerry Pournell. 1974. (2:02) - "Huevo de Dragón" de Robert L. Forward. 1980. (3:13) - Comentarios de los oyentes y despedida. (3:56) Nos acompaña el jazz de Sonny Rollins y cerramos con el clásico "Transmission" de Joy Division. La sintonía, como es habitual, es el tema "Spectre Detector" de los Tiki Tones.

Head on over to https://www.patreon.com/LetMeSumUp.—It's time to revive *US elections corner* at LMSU HQ and HOOOEEEEE there is a lot to say! Summerupperers, we could have spent the whole pod unpacking the various permutations of the makeup of Congress and its implications for climate policy. BUT, beyond Democracy Good, Demagogue Bad, a re-elected but weakened Biden may be relegated to Executive Actions and bedding down IRA and getting proposed EPA standards for cars, powerplants and oil and gas methane reduction up. Will it be enough? The spectre of a Trump 2.0 presidency would see the US withdraw from Paris again and completely remove climate considerations from all decision making to the extent possible. The wildly popular hurricane of carrots that is IRA may yet survive though.Our main paperLast week the Government released two papers relating to adaptation - the National Climate Risk Assessment : First Pass Assessment Report and the National Adaptation Plan Issues Paper.  Your intrepid hosts are here for this culinary climate cabaret! We devoured the National Adaptation Plan Issues Paper, with a little First Pass Climate Risk Assessment amuse bouche! One more thingsTennant's One More Thing is “Indistinguishable From Magic” by Robert L Forward, a collection of mind-expanding essays and indescribably dreadful fiction on the frontiers of future science and engineering by an influential aeronautical engineer and physicist. Featuring incredible levels of energy inefficiency!Frankie's One More Thing is a great episode of David Roberts' US climate pod of note ‘Volts' called “How's IRA doing?”. It's a cracking discussion with Trevor Houser of Rhodium Group unpacking data on how successful the IRA has been, two years into implementation. Luke's One More Thing is to flag ongoing and significant work underway by Treasury and the Australian Sustainable Finance Institute on a regulatory regime for Climate Related Financial Disclosures - due to kick off this year! - and accompanying taxonomy for sustainable finance.And that's all from us Summerupperers!

Randy shares some of his favorite papers with Jim: papers on general relativity by engineer and science fiction author Robert L. Forward on how general relativity could be used in a terrestrial environment, including proposals for devices and materials. These papers are "General Relativity for the Experimentalist" and "Guidelines to Antigravity." Show notes: http://frontiers.physicsfm.com/6

This week we have a full Fringeworthy episode, but we are really talking non-game specific about what super tech is and how it might appear in your games. This is another episode that was found hiding on my hard drive for nearly a year so the sound quality isn't to our current standards.  Please forgive.
