Thing is, though, physics does change. Nobody in the 19th century would have thought that we could get vast amounts of energy out of uranium (which they used to glaze pots!). And they thought they had it ALL figured out too.

If it doesn't involve throwing something out of your spaceship (a rocket) or throwing something AT your spaceship (a photon sail etc.) it's all SF to me LOL

I don't deal in speculative physics, though, I don't understand it yet

like Alcuberries warp drive (probably spelled that wrong)

I didn't mean "science book" like that, more a book of speculation that has some grounding in mathematical ideas

No science book would have an interconnected network of interstellar distance gates though.. :)

I definitely agree that the fiction bit is relevant, it IS science fiction after all

30 Jun 02:27

I just can't find much details, maybe the idea is totally discredited now?

30 Jun 02:27

Sure

I think Joe Haldeman got the idea from some physics speculation though

The fiction bit is relevant

30 Jun 02:27

Mechanizoid

purely speculative of course

Nah, someone did the maths once, Carl Sagan mentioned it

Science fiction man

Well propulsion speculation books

Yeah, but collapsar is an old term for black hole :-) And I've seen "black hole gates" described in science books

30 Jun 02:26

Amit Dutta

--

They are basically......stargates! Lol

30 Jun 02:25

Amit Dutta

Pretty much...the tech isn't described as black hole gates in the book..I just used your words :)

30 Jun 02:25

Mechanizoid

--

don't black holes just rip you apart with tidal forces if you get near them?

30 Jun 02:24

Mechanizoid

--

the concept doesn't seem to be the same as a wormhole

30 Jun 02:24

Mechanizoid

I heard about "black hole travel" in books and stuff, but I can't find any details on how black holes could make travel shorter

30 Jun 02:24

Mechanizoid

--

I am a bit confused by that

30 Jun 02:24

Amit Dutta

--

No so, the book was using "collapsers" I jist looked it up, so yeah black hole gates or something

30 Jun 02:23

Mechanizoid

--

That would... kind of totally suck, LOL

30 Jun 02:22

Mechanizoid

--

What if we found out it worked in reverse, the faster you went the longer the trip seemed to the travellers?

30 Jun 02:22

Mechanizoid

--

With FTL travel, though, how would time dilation apply?

30 Jun 02:22

Amit Dutta

--

Oh yeah that might be it

30 Jun 02:22

Mechanizoid

--

I was amused that the "micro-ton" grenades would only be as powerful as a firecracker

30 Jun 02:22

Amit Dutta

--

Hmmm. I can't remember to be honest...I thought it was just ftl drives of some sort, but I might be wrong

30 Jun 02:21

Mechanizoid

And you had to travel at relativistic speeds to get to the portal.

30 Jun 02:21

Mechanizoid

He used the idea of naturally occuring black hole gates, right?

I was listening to that on CD, but the disk was broke. :-(
