Does space bend In a pure vacuum ?

[paddoboy]

Not really

Actually with 100% certainty.
Or if you like you can explain,

or explain the Lense Thirring effect that has been validated.
here this one river....

The lensing effect is how you look at it .

From me its matter in space that is the essence of lensing .

Bingo!!!! Not bad river....with the photo for instance, an intervening massive galaxy, has lensed the galaxy/Quasar, which is further away, so that observers on Earth see four of the same object.
Depending on various positional aspects we can also have this....

or this......

Isn't astronomy/cosmology and science awesome river? see what you can learn?

So there is NO matter in this space ?

I'll explain once more river....Gravitational lensing is caused essentially by light following geodesics in curved spacetime: The Einstein Cross picture for example is the light from a very distant quasar, being lenses by the spacetime curvature of an intervening galaxy or group of stars...like this...

Note that the line go through the outside spiral arms of the galaxy . And those spiral arms have matter .

Look more closely .

So? It's the collective group of stars that warp/curve the spacetime in that vicinity, and the light from the distant quasar follows the geodesic path.
You understand geodesic?

The light doesn't go around the galactic arm , the light didn't circumvent , the galactic arm , it went through it .

 

[paddoboy]

The light doesn't go around the galactic arm , the light didn't circumvent , the galactic arm , it went through it .

The light followed the geodesic in curved spacetime as per the illustration and the accepted science.

 

[paddoboy]

And of course river, knowing what high standards you put science under, you are referring to and observing a simple illustration to illustrate to the average person, what is happening.

To my quote above ;

Hence light went through matter . Obviously .

Light went through matter .

Sorry river, we have absolute evidence for gravitational lensing and light following geodesics.
Your "hence" is based on nothing other then your usual personal pseudoscience take on things.
But you have fun with that.
Or if you like you can add some science in the sciences section re spacetime warpage and BH's.

 

[paddoboy]

Plus of course river, you could explain how we get the "actual image" of an Einstein cross, and/or the actual image of the other example of gravitational lensing, IF the light is going straight through like you imagine.

 

[paddoboy]

Hey river old beast!! here's another illustration.

Light went through matter .

 

[paddoboy]

Light went through matter .

All of it?
Again, please explain how we get the actual Einstein cross image and other gravitational effects images.

Choosing to stay the village idiot, is no skin off my nose river.

Matter in Space .

Your post # 374 was an illustration . Irrelavent .

So was 365 just an illustration and yet you stupidly grabbed hold of it with childish glee, claiming light went through and dismissing the gravitational lensing in the obvious real photos.
No wonder you have been confined to the fringes!
But again anyway river, explain the four stellar images in the Einstein cross? I know you can't. Instead just because of your relationship with me, you chose to act the village idiot rather then admit once again, you are wrong.

Bye river...I have a few science threads to put up shortly...hope you learn from them and enjoy them.

Light through matter .

In a pure vacuum light would not bend .

Gravity in a pure vacuum , would not bend light because gravity has nothing on which to grasp , its self onto . Gravity cannot bend space in a pure vacuum . Because no matter exists in space , in the vacuum .
