A Star Gate to Washington DC opens tomorrow

A fourth gravitational wave has been detected. Three solar masses worth of gravitational energy released, leaving a 53 solar mass black hole behind.

As I do my now more than highly polished presentation on StarGates:  the Theory & Practice.

New developments, just in the last week:

  1. A fourth gravitational wave was detected last week, 9/27/2017.  This was far more finely localized than the previous; 25 observatories are looking for signs of the event in the electromagnetic spectrum.
  2. And Kip Thorne — inventor of scientifically plausible StarGates — was awarded the Nobel Prize this week for his work on developing feasible gravitational wave detectors.   Perhaps someday he will be even more famous as the inventor of StarGates!

So I’ve folded these in my talk & look forward to giving it tomorrow at 3pm at Capclave, the Washington DC Science Fiction Convention. If you are in the area, I hope to see you there.

PS.  I will also be on a panel on Engineering in Fantasy & Science Fiction:  I love it when we discuss the thermodynamics of magic & the magic of engineering!

And a followup:

Followed Tom Holtz at Capclave:  this is always good & bad:  good because it guarantees a nice crowd, bad because he is a hard act to follow.  The assembled multitude was enthusiastic, always nice.

And the panel on engineering in F & SF also went well:  Fran Wilde did a great job moderating, had a good supply of questions & made sure everything had a whack at each, so not the usual domination by 2 or 3 of the more talky types. Audience lively (in a good way, not in the hurled rutabagas way.)

StarGates Jump to FossCon — The Free & Open StarS Convention!

9/3/2017: I have just posted the slides from Fosscon on slideshare.  Comments, questions, problems, & buildable blueprints, all very welcome!


This coming Saturday I’ll be doing the latest revision of my StarGates talk at FossCon, the Free & Open StarS Convention!

(Pay no attention to those who assert this is the Free & Open Source Convention, that is a mere cover story.)

The convention is at International House in Philadelphia, starting at 9am, and is free.  As to my talk:

“Call them Stargates, Jumpgates, Fargates, Hypergates or just an invitation to every pest from the far reaches of the Galaxy to visit, they would be invaluable in helping mankind break free of this solar system.

Are StarGates only a convenient plot device — or could they actually be built? Accordingly to Einstein’s Theory of General Relavity, they are possible — at least in principle.

We will discuss 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.”

My talk’s at 1pm.  Hope to see you there!


And there I have you seen!  There was a nice turnout (in the South America room at International House) with a lot of questions.  We finished with a few minutes for additional questions, including my favorites:

What happens if you drag a wormhole through a wormhole?

I congratulated the questioner on the question & he just pointed at his young son sitting next, a lad clearly with a bright future as a scientist!

I had to admit I wasn’t sure, but I suspect it would be bad news for all concerned:  both wormholes, and any spaceships, space stations, or space-persons nearby!

How do you think this might actually be done?

I focused on wormholes because that is far & away the most popular of the approaches.  But if some sort of stargate were ever actually to come to fruition, I suspect a combination of the Einstein-Rosen-Podolsky (EPR) effect and the ideas behind the Krasnikov tube would be at work.  The EPR effect is the spooky-action-at-a-distance Einstein objected to; the Krasnikov tube is an idea of — curiously enough — Krasnikov for laying out a tube of warped spacetime behind your slower-than-light spacecraft.  You’d have to go slower-than-light while laying out the tube, but could use it for faster-than-light thereafter. And as I said in the talk, negative energy & vortices are pretty sure to be involved.

 

 

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!
