Neil DeGrasse Tyson: "My measurements trump your faith" Quote of the year!

[@michaelvorster2846]

I have a low level to no knowledge of astrophysics and all things scientific - however I continue to listen to hours of Neil de Grasse-Tyson’s presentations and love it - each episode makes this 'science dummy' feel like I know something - my working knowledge is growing. Thank you ever so much Neil and your team. I love Chuck - he earths the programme with his highly intelligent wit and humour.

[@samadams164]

I'll speak up for ya Neil. While I don't know the "helicopter experts" of whom you refer, I can recount my experiences as a combat heavy lift helicopter aircrewperson, and confirm your original statement. As a general rule, helicopters "fall like rocks" (in contrast to airplanes) when they lose all engine power. As for auto-rotation, it works better on some helos, than others...but, it ONLY works IF you have sufficient altitude in which to create the necessary amount of lift before hitting the ground. Since the majority of rotary accidents occur immediately after take-off, or prior to landing, this technique is 100% useless (my VA disability rating verifies this) because there is not enough time to induce the air pillow. Yet in my aircraft, for instance, auto-rotation is still subject to elevation(atmospheric density), wind, humidity, gross weight; and if any of those conditions exceed a threshold when the power loss occurs, altitude be damned, it's going to leave a mark! When the main rotor(s) lose power they DO NOT produce enough lift to keep the helo in the air, it's the reason for having powerplants (engines) in the first place! They dont propel the helo through the air, they turn a shaft which, through transmission gearboxes, turn the main(s) & tail. Carry on...

[@Solusspiritus]

Scary stuff

[@shaunmitchell2069]

Is the number of rotor blades a factor?

[@samadams164]

​@@shaunmitchell2069 On the whole, yes, more blades give more lift, but it doesn't scale linearly, across the various types. Although, the amount of blades are more indicative of its expected operating weight.

[@shaunmitchell2069]

@@samadams164 thank you and stay well

[@nHans]

Yup, I concur. After watching this video, I did something I had never tried before. Took a chopper high up in the sky and deliberately cut the engine. It fell straight down and crashed. I wasn't able to control it at all. With airplanes, on the other hand, I have lots of experience landing them despite engine failure and other catastrophes. (Full disclosure: I've never crashed a real airplane or chopper. Never flown one either. My experience, though vast, is limited to MS Flight Simulator.)

@@KoRntech Yeah true, but not bad for a not-radio-expert. I would've liked to have mentioned the key aspect of _ratios_ of antenna length and wave length, as well as advances on antenna miniaturization like fractal antennas (which relates closely to the coiled-antenna design). The latter really gets to the heart of why we usually don't even see antennas these days. But to the extent that so much of our radio communication these days is done using microwaves, I think the answer he provided sufficed superficially.

Of course but the question is who will.

[@theduder2617]

I'm all for it, but what frequency is what musical note? Is 3 quick fluctuating frequency blasts note A, note F, or is it a pause? What would determine tempo? I could waste everyone's time by continuing, but it is easier to state that there are so many variables to consider. Where do we start so to speak. lol We can and have directly rendered emitted radio waves into sound. Such as with planets and even distant stars. Of all I have heard, a pulsating neutron star sets more of a tempo than radio wave sounds from our sun. All I do know for certain is, I surely will not be the creator of said algorithm. lol

You could probably get some piano samples, and take measurements of the radio waves every quarter second. Average out the frequencies that are received and turn them into notes.

[@caladonn2659]

On the Final Question, you mentioned the fact that if the Sun was snatched away we would not notice it for eight and a half minutes. This is definately true for light and the other wavelinks of energy the Sun emits, but what about the loss of the gravity field the Sun also causes? Would the Planet immediately jolt outbound from it's current orbit? Or would we continue in the same Orbit for that same eight and a half minutes?

[@JaguarBST]

Effects of gravity is also confined by the cosmic speed limit. Evident from the fact that gravitational waves of collapsing black hole emitted 1.3 billion years ago was detected in the year 2015.

Neil actually mentioned it in his answer but you must have missed it - yes, the Earth does stay in orbit for 8,33 minutes after the Sun disappears, because gravity also propagates through space at the speed of light, not faster.

I have the same hope as you Mr. Tyson that it dark matter is gravity of an alternate dimension, that balances perfect basic laws of physics. But when you stated it as a particle instead of a force makes me think maby the other family of particles is the negative versions of the one's we're familiar with, aka equal negative charge thus the lack of interaction because it is the balance to the positive charges we measure.

Quick question for anyone who knows: If the sun were suddenly plucked out of the solar system, how would that affect our orbit around it? Would we feel the effects BEFORE seeing it? In other words...does the speed of light (the universal speed limit, as it's fondly referred to as) also limit gravity? Would we continue the same orbit without the sun for Less Than than 8 minutes? Wouldn't that break the cardinal rule?

@@Cabrera1027 Gravity works in a very different way light does. Gravity is the emergent entity when something with mass takes an area in spacetime. In E=mc² c=the speed of light so I wouldn't say it has no bearing on it. Dark matter/energy, photons, gravity, to name a few. Anything that doesn't interact with the Higgs field as well. It doesn't have to be liquid though, if you add mass to the moon it'll increase its gravitation pull on the Earth and the Sun's pull on it will also increase. During a new moon or full moon the added tug from the Sun due to its position does help to raise the tides. Im sure it'll be the same case during an eclipse. Edit: grammatical errors

@@jasonanderson1843 weird. I nearly dreamed the emergent part of gravity. What I mean with E=mc² is, with no mass, a photon is incalculable?

If... (With fake numbers inserted here because I don't know the proportions off the top of my head) 10 gravity pulls on earth from the sun, and 1.5 gravity is pulling from the moon, I'm looking at when the moon crosses in front of the sun. Does the combined pull equal 11.5 gravity, or 15 gravity? With that being in mind, is there a discrepancy between the numbers, such as 11.4, or 14.995? Something that would indicate the effect isn't perfectly multiplicative, of additive. Sorry about the...wordy reply. I don't really think in straight lines, I scoop info in heaps 🥴

If time only moves outward,almost asif repelling its self could it be a logical theory dark energy or matter could be related to or even particals of time since they repell matter and it doesnt interact with anything known and one of the only things i could think of that interacts with nothing but affects almost everything would be time. Love star talk its one of the few intellectual shows that draws me in and makes me think.
