Neil deGrasse Tyson Explains Gravitational Waves and Gravitons

Confused about gravitational waves and gravitons? You’re not alone! Especially since we’ve never directly detected either one. But, as Neil deGrasse Tyson says to Leighann Lord in answering a fan’s Cosmic Query, “We’ve got top people working on it.” Find out about LIGO (the Laser Interferometer Gravitational Observatory) and how we’d know if a gravitional wave passed across us. You’ll also hear about how a scientist from Bronx High School of Science won the Nobel Prize in Physics for using binary pulsars to measure gravity waves.

Those top people working on it did a fucking fantastic job!

[Muzeishen]

They did it! Gravity waves are now a real thing. Please do another episode dedicated to the findings!

Meanwhile at the LIGO:
Scientist seeing the monitor go off "Sir, There is a disturbance in the force"

[shirafingerer]

We had someone from LIGO give a talk at NYU, and before there was a student hour for undergrads and it was a fascinating discussion

[gabrielgomesbrito]

"We have top people working on it" Who? Top...people...

[OdinMagnus]

Would you then say, "there is a disturbance in the force (of gravity)"?

[Coastfog]

I want Neil to tuck me in and read me bet time stories about astrophysics. I'm 29. Am I weird?

[AndrewMdub]

DEFINITELY have to rewatch this video, cause most of that flew over me.

[indigolarry]

Need a follow on this! As gravity waves have been observed since this video.

[PrimusProductions]

If gravitons travel at light speed, they should be massless, right?

[SnoKing]

Why not record and upload the entire podcast?

[timwatley]

please do more of these with this interviewer. She's cool.

[eddohan]

We did detected them! Congrats seince!

Gravitonic ambiance is worth the Nobel Prize of Mathematics
-> Anywho demonstrate the curvature of the circle is unnattaible to other mathematicians is worth it
<- The curve is eternally encoded in geometry's memory
>-< wave-particle absortion is disruptive coherence, contact is layers's step written as yet another dimension, light has no speed to lower bounds it only accelerate, a rewinding black hole of photonic steps gets you there instantaneously as it reaches you, the weaker the field the more energy-space in the system but lighter than vaccum floats too

Gravity is merely a path of least resistance for matter. More mass = slower time the closer mass gets to it. Slower time is  least resistant to the existence of matter. There is no way I can prove this, I'm just a bunny. 

[julianhart]

This is a very clear concise explanation - Thank you

A Big Gravitational Wave Announcement Is Coming Thursday June 29th…. This is better then a time capsule 🎉❤

[XDRONIN]

StarTalk Radio  To Mr. Neil deGrasse Tyson.. Question - IF there is such thing as Gravity waves.. Are there such things as Gravity Currents?? (like Sea-currents)

[ron]

So thats somewhat vague. The answer makes sense in the context of large sources of gravity coming in contact with each other, but what about "stationary masses" ? IE the earth, and all the gravitational forces present on it based on the quantum model? Where do waves and gavitons fit in there? Or do we only look at those objects through the Einstien model?

Would it be safe to say a gravitational wave and its magnatude exists with a frequency relative to its mass in all objects, that we cannot measure because A: the influence of earths gravity and low frequency makes it impossible to measure? (eg: its like trying to measure out half a cup of water while sitting submerged at the bottom of the ocean) or B: because of the constraints found in A, and the sophistication of the tech required to make those observations would only be possible on earth at the moment?

Whats the theory, since Im coming up with my own ideas here.

Also, could you perform the same experiment on a different gravitational body at the same time (ie:the moon) to observe the difference in frequencies as a gravitational wave passes through both bodies? Would we expect identical results? I mean, by doing it on the moon with the same calibratation done on earth, it wouldnt be subjected to the same "noise" as it would on earth....

TLDR: I realize I let my mind wander a bit, but the bottom line is: how does gravity and waves fit outside of a high gravity collision event that explains the gravity we experience on earth within the quantum model?

[johnregan]

I am confused, if gravity waves and gravitons not yet detected and not yet fully understood can not exeed the speed of light how can its force or speed of force move faster that light when gravity in the form it appears in a black hole will not allow light to escape? I am far from qualified to answer this and do not know enough of the workings of physics or quantum physics to understand this awesomeness, yet my mind can not rest on this matter and it hope it can find an answer from you all. :) thank you :)
