Relativity Tested with Supermassive Black Hole!

Relativity Tested with Supermassive Black Hole! For the first time, astronomers tested Einstein's theory of general relativity by detecting gravitational redshift from the supermassive black hole at the center of our Milky Way galaxy!

2:18 I love your sense of humour, in so many videos.

[SquishyMit]

Hey Christian, I found your channel a week ago and just love your content and presentation! I don't know why you don't have over 500k subscribers! It will happen! Keep up the great work!

[MarkNokalt]

A very thorough and enjoyable video, keep'em up! :D

[GetToTheFarm]

love it and the new channel name should bring you tons of followers!

[StoneyCreekHeritageFarm]

Very interesting! Thanks for taking the time to discuss this and share in a video format. Your channel is very Intriguing indeed!

[ahnaftalukder]

Oh, shoot. Didn't expect to get into watching the whole video of a random channel. I'm quite shocked with the quality of the content. I subscribed:)

[ThisSingleMom]

Great graphics and presentation. I like to learn something!

[PurpleHelmet]

throwing me a curve ball with the channel name change! Love it, another fantastic professional and informative video, Im fascinated!

ps

cool shirt 😂

I like the new branding and entertaining style 😊 Same easy to understand content. I wonder how much this star was stretched like a football during that kind of acceleration.

Great channel! I subscribed.
A star moving at .25c would red shift on its orbital retreat from us and blue shift on its approach right?

[GetToTheFarm]

oh wow, watched to EOS original and your explanation made so much more sense!!

[jimyguitar]

Space rushing into earth causing weight.
Space rushing faster into a black hole causing extreme weight.
Rushing space near a black hole causing red shift.
Similarly a force from accelerating in space is space passing through objects on earth.

How do we know the redshift is from the star’s proximity to the black hole, as opposed to being from the star moving away from Earth rapidly at that point in its orbit?

[chromebook]

Can we measure the gravity force between two neutron particles?

[RovingPunster]

AFAIK, UCLA's Galactic Center Group has NOT yet released their final analysis of phase 3 of this study (at least not on their official website anyway). It was supposed to be done vy Nov 2018, so it's overdue.

Ive been waiting for months, so if you hear an update on that, please let us know.

I have a question for you sir my name is paul roche and you’re talking about the event arising everything goes in the event a rising nothing comes out except for microwaves or something what’s on the backside of the event horizon another words if you go toward the event horizon and you go around and you come up behind it is they’re similar to the black hole behind it or do we not know yet I appreciate a comment but this is something that’s bugging me for a while now you always talk about what goes in and I understand nothing can come out of it but if you go past where the black hole sucks everything in and you go behind it what would you find thank you bye

[gamerharshaop]

Newton theory works correctly in a planet under land gravity and einstein works more at space gravity

[cygnus]

Was there time dilation from the stars perspective?

[RovingPunster]

Forgive the presumption of an amateur, and I intend no disrespect with this, but my impression is that people are playing games with semantics when they claim BHs emit neutrinos. Black holes, by definition, EMIT NOTHING, because they are literally a hole (think spherical analog of a whirlpool) that nothing exists within (including space time itself) ... no imaginary point mass of infinite density that the black hole is merely a consequence of, but rather nothing at all because it is the warp in spacetime itself that is the true phenomena, and as it grows, it does so not by accreting matter into a point mass singularity within the hole, but rather by absorbing and converting energy from the event horizon to grow the warp itself ...

To summarize, the only things that can and do escape (e.g
Neutrinos) do so from within the event horizon (as a result of matter being shredded into energy), and just like the wake of a cargo ship, the event horizon lies OUTSIDE of the hole it orbits, and thus it would be more accurate to itentify THAT (the E.H.) as the source, not the hole itself. It is the same distinction as between a star and the solar system that orbits it ... if a passing space ship observed a radio transmission, it would be imprecise to say it came from Sol, rather than its true origin (Earth). Make sense ?

My background is compsci, and semantic/linguistic precision is a cornerstone prerequisite for the field.

Come on. To actually test the theory of relativity send a classical two mirrors interferometer to the space station and take measurements outside of the station in a vacuum of space. After this the theory of relativity will rest in piece, as the theory of Heaton did. I mean the Heaton as a particle of heat.
