StarGate to Baltimore Opening in Six Days!

Beware of Unexpected Doors!

Call them Stargates, Jumpgates, Fargates, Hypergates or just an invitation to every unwanted pest from the far reaches of the Galaxy to visit, they are absolutely necessary if we are to have the glorious Science Fiction action we desperately need.  Could they actually be built?  Modern physics may permit, but: how to glue black holes together to build a wormhole, how to avoid the dangers of spaghettification, radiation poisoning and paradox noise, and just what would it take to build one in practice?

I’ve just finished revising my StarGates — the theory & practice — for Balticon. It’s a Good News/Bad News thing: Bad News: we don’t know how to build them, Good News: we can’t prove we can’t, someday!1)(Or is that Good News:  they can’t get to us yet, Bad News:  but they just might anyway.

Slides for talk now up on SlideShare; comments & questions very welcome.

Talk will be this coming Saturday, May 27, 9am at Balticon. If in the neighborhood, drop by. If not in the neighborhood, spin up a stargate & jump in!

Stargates: The Theory & Practice

Doors and Portals and Stargates, Oh My!

Call them Stargates, Jumpgates, Fargates, Hypertubes or just an invitation to every unwanted pest from the far reaches of the Galaxy to visit, they are absolutely necessary if we are to have the glorious Science Fiction action we desperately need.  But could they actually be built?  We look at what modern physics has to say:  how to glue black holes together to build a wormhole, how to avoid the dangers of spaghettification, radiation poisoning, and paradox noise, and just what it would take to build one in practice.

This was a talk I did at the last Philcon, went over well.  And I had a lot of fun doing it.  I’ve got it up as a talk on slideshare.  And I may do variations on this at the 2017 Balticon & also Capclave.

It is the kind of subject you can go anywhere with!

 

Just How Many Universes are There, Anyway?

I did my talk on the multiverse at Balticon Saturday (5/23/15).  Went over well:  SRO & good questions.

I’ve posted on slideshare:  How many universes are there, anyway?

Questions welcome!

Just how many universes are there, anyway?

As usual with Balticon, I came up with the title before figuring out the talk.  This year it is:

Just how many universes are there, anyway?

Why do many physicists think there may be an infinite number of universes?  What would they be like?  What might life be like in parallel universes? How might we detect them?  Could we travel between them?  And what does quantum mechanics have to do with the multiverse?
This will be at my favorite time slot, 2pm Saturday (the 23rd of May this year).  Now all I have to do is whip up some content.  Would I were in one of the infinite parallel universes in which I have already done so!
