Massive stars fuse heavier elements in their cores than lower mass stars. This leads to the creation of heavier elements up to iron. Iron robs critical energy from the core, causing it to collapse. The shock wave, together with a huge swarm of neutrinos, blast through the star’s outer layers, causing it to explode. The resulting supernova creates even more heavy elements, scattering them through space. Also, happily, we’re in no danger from a nearby supernova.

Lecture I in my Psychological Significance of the Biblical Stories series from May 16th at Isabel Bader Theatre in Toronto. In this lecture, I describe what I consider to be the idea of God, which is at least partly the notion of sovereignty and power, divorced from any concrete sovereign or particular, individual person of power. I also suggest that God, as Father, is something akin to the spirit or pattern inherent in the human hierarchy of authority, which is based in turn on the dominance hierarchies characterizing animals.

Q & A Starts: 1:57:25

Mantra "Om Namah Shivaya, Sathya Sai Baba" para pedirle a Sai que se levante y que su cuerpo vuelva a la vida para que reanude las tareas que tiene asignado para redimir y conducir a la humanidad.

¿Cómo superar el dolor en un mundo que no nos enseña a mirar hacia dentro y ser conscientes? ¿Por qué hoy son tan escasas las buenas relaciones con nuestros semejantes? ¿Qué nos enseña la muerte del prójimo? ¿Por qué es vital saber perdonar al otro y perdonarse a sí mismo? En Entrevista, de RT, el psiquiatra chileno Claudio Naranjo, uno de los invitados más vistos de toda la historia de nuestro programa, comparte su sabiduría con nosotros.

Un falso video que se volvió viral a través de WhatsApp en India y que muestra el supuesto secuestro de un niño ha provocado una ola de linchamientos.

Se trata de una película grabada en Pakistán para concienciar sobre la seguridad de los niños en el país asiático.

En la versión original, el video acaba con uno de los hombres de la motocicleta levantando un cartel con el lema de la campaña.

Pero esa parte fue eliminada en la versión que circula por WhatsApp en India y está generando rumores sobre bandas de secuestradores de niños.

Uno de esos rumores causó la muerte, en mayo pasado, de Kaalu Ram, un chico de 26 años que llegó a Bangalore en busca de trabajo.

El suyo es el noveno caso de linchamiento que las autoridades de India atribuyen a rumores falsos que circulan por las redes sociales desde el pasado mes de abril.

La policía está lanzando varias campañas para evitar la difusión de ese tipo de mensajes.

Video producido por Dan Johnson, Varun Nayar y Shalu Yadav.
