  1. Great first show! After the first few minutes you really got into the swing of things and I really enjoyed the show. Is there room for improvement? sure. But I think you are off to a great start, and this will be a great weekly podcast!!!!

    • thanks. Yeah, there are a couple humps we’ll need to get over before i start posting these to itunes. thanks for the encouragement!

  2. So, my “website” is a very basic picture of one thought I had as to why things could be accelerating at an increasing rate the farther we observe them. My thought process was that our observable universe isn’t necessarily the only universe in existence, and that the rest of the overarching universe would be stretching our universe as it got closer to more mass (gravity effects). Is this logical to even consider or why am I wrong to think this is a possibility?

  3. My rudimentary logic has led me to ask the same question. I would like to see an expert respond to your theory. Are we indeed part of an “omniverse” which encompasses the unobservable as well as the observable? I have just been made aware of this site and I am enthralled by its content; I am very impressed by the host and the guests and their unique way of making scientific issues understandable to the the layman. Thanks so much.

  4. What would happen to a black whole in the big rip? Would it also start to expand? If it does begin to fluff out like everything else, would there be a point before the big rip when it starts to emit light and matter? If it doesn’t could our rag tag heroes tow the solar system close to the event horizon to save us?

  5. would the big rip also influence black holes? If so, what would the tipping point between a sucking black hole and a repulsive black hole look like? If not, could our rag tag heroes save us by moving closer and closer to the event horizon?

    • I’m not an expert by any means, but I can visualize the rip pulling on the black hole, increasing its tidal forces and increasing its rate of hawking radiation at the schwartzchild radius. Where super-condensed space meets stretchy-space, the black hole’s evaporation would increase until it went poof, right?

      • I’m thinking that the black hole would largely maintain it’s size and density, but effects AT the event horizon would become more conducive to Hawking radiation. What I’m imagining is the space IMMEDIATELY outside of the event horizon being stretched while the space inside the black hole remains unchanged, but since gravity on the outside is being “stretched”, the paired particles of Hawking radiation find it easier to escape, so the phenomenon would accelerate..
