.Scott replied to the thread Undergrad What determines if wave components are independent vs coherent?.It's simply whether they are in phase or not. If you know they are the same frequency and in phase, then they will "constructively...

.Scott replied to the thread High School Thought Experiment: Behavior of shadow of object moving at speed c.For the general case, this is a very interesting question. But for simplicity, I will answer a much more limited case. Let's say that...
-
.Scott replied to the thread Electric power distribution from powerplant to homes.Power lines are resistors. The more current that flows through them, the greater the voltage drop from source to user, and thus the...

.Scott replied to the thread Insights Quantum Entanglement is a Kinematic Fact, not a Dynamical Effect.If someone asserted to me that "wave functions really exists", I think I would just let it pass. I would view that as an issue of...
-
.Scott replied to the thread Insights Quantum Entanglement is a Kinematic Fact, not a Dynamical Effect.Is there a "constructive explanation" that does not invoke "hidden variables" and that could not be considered an alternate...

.Scott replied to the thread High School Looking for info about the Sombrero Galaxy.That Hubble photo shows some serious gray-scale contouring. This happens when the brightness/contrast is set to highlight a limited...
-
.Scott replied to the thread High School Looking for info about the Sombrero Galaxy.A planet that orbits a black hole without also orbiting a star would be missing that nice steady warmth and glow of a sun that continues...
-
.Scott replied to the thread High School Looking for info about the Sombrero Galaxy.It's also crazy big. In the night sky, it is magnitude +8.0. So, you would need (at least) binoculars to see it.

.Scott replied to the thread High School Looking for info about the Sombrero Galaxy.You can try a search on Messier 104, it's astronomical designation. It has a wiki page. As you likely already know, it about 30,000,000...

.Scott replied to the thread Any plausible non chemical rocket based space launch system on Earth?.It's worse than that. At low altitudes, the rocket needs to throttle back to limit aerodynamic forces. So, you have a combination of...

.Scott replied to the thread Any plausible non chemical rocket based space launch system on Earth?.How about using a balloon to carry the second stage to 30Km altitude. If you use this in your story, I wouldn't call it "Acme Space"...

.Scott replied to the thread Insights Quantum Entanglement is a Kinematic Fact, not a Dynamical Effect.When you say "constructive account", does this differ in principle with the "hidden variable theory's"? I think it's normal for any...

.Scott reacted to DaveC426913's post in the thread Any plausible non chemical rocket based space launch system on Earth? with
Like.
An incremental advance in carbon nano-fibre tech? Last I heard, the rate-limiting step wasn't the strength of the fibre, it was the... -
.Scott replied to the thread Any plausible non chemical rocket based space launch system on Earth?.By "It", I am guessing you mean the SpinLaunch system ... And by "it", I am guessing you mean the SpinLaunch second stage. Yes, a second...

.Scott replied to the thread Any plausible non chemical rocket based space launch system on Earth?.Perhaps "SpinLaunch", which is cargo-only. Also, if you are looking to avoid "big, expensive", then a space elevator wouldn't fit the...
