Mass/energy curves spacetime. This means the light is still traveling in a straight line but the space is curved.

so if we could flatten out all the curves, maybe the mass disappears

It can't be explained by science. God just makes it happen.

one thing to contemplate is that we have intuitive understandings of what is meant by mass and energy, but those understandings do not jibe with the physicists' admission that we don't know what anything exactly is, the best we can do is come up with models and poke at those long enough until we find they aren't agreeing with some observation and then we get to celebrate that we found something else that we don't know. that is, sure, we didn't know it before, but at least now we can describe what we don't know with more specificity

The concept of one God is a fairy tale. Conjured up by a few Jews back in the day. A very limited IQ type of God that could only cum up with Incest as a way to build a community.
As to gravity affecting light - I believe it was Einstein (another Jew) who explained that even thou light (photons) have no mass, gravity not as a force, but as a curvature of spacetime caused by mass and energy. This can effect and bend light.

Meta IF you have access to the Science Channel there is a series that does a great job educating people on all this works.
One of my hobbies is the study of Quantum Physics and the math is totally HARD as all Fuck to learn. Getting two totally different solutions to the same problem and both are correct.
Of course people like Dave are ignorant on how a Problem can have multiple solutions and all may be totally correct.

Still salty about not being able to solve the horse/fly problem I see :) I'll be giving the solution soon and then you'll see where you've been going wrong. Stay tuned!

Trying to solve the horse/fly problem destroyed my marriage, got me addicted to crack, and left me homeless for a period- but I am closing in on the solution. I just need a bit more time and I will have it.

Actually I am most pleased about the outcum of the horse/fly problem. You work for the Catholic Church and you damn well know how I feel about that foul disgusting as all fuck Pope run Church.
Watching you get banned from TC was a Joy. You are more proof Priests should never be trusted. You gave your solemn word and of course your words have so little value. You're good at bull shit and can brag about being paid to bull shit.
And I solved that problem with 3 solutions and Chat GPT agreed with just one of my solutions.
Define Lateral Thinking: "lat·er·al think·ing
noun
The solving of problems by an indirect and creative approach, typically through viewing the problem in a new and unusual light.
Therefore multiple solutions are possible.

Nope, there's only 1 solution. Stay tuned for it!

The light goes straight, but the actual space that it travels through is warped by gravity.
tteh !MemesToDNA joined in and replied with this 5 months ago, 23 hours later, 1 day after the original post[^] [v] #1,384,939
Because gravity in general relativity isn't a "force" pulling on mass, it's spacetime curvature. Light always travels in straight lines but straight means geodesic, the straightest possible path in curved spacetime. So when spacetime is bent by mass/energy, those geodesics bend too. Light doesn't need mass to be affected, it just follows the geometry.

But this makes no sense and basically contradicts the definition of gravity which is mass attracting mass.

That's the Newtonian understanding. Einstein upended that quite some time ago I'm afraid lol.

Light is part of the physical realm, mass, energy, relational time. We see the energy or light. Black holes affect at least our understood physical realm, gravitational forces.
But not all energies or force, need to relate to our relative understanding of this physicality.
Waves themselves are time. Some things should be unaffected by black holes. Then there's scale issues of space and time, which brings us back to relative understanding.

I don't believe in space time curvature as that's relativistic.

If it has nothing to do with mass, why do massive objects "bend" "spacetime" more than non-massive ones??

You said mass attracting mass, actually it's mass curving spacetime and the objects fall down the curve

I didn't say it has nothing to do with mass. More mass does mean greater spacetime curvature. I said gravity isn't "mass attracting mass" (a Newtonian simplification that relativistic physics overturned), as evidenced by the fact that light (which has zero rest mass) is impacted by gravity. Consider also gravitational time dilation etc. thanks.

Because the mass of the earth attracts the mass of the marbles to it, which humans perceive as “down”. If the bowl is appropriately shaped this is perfectly normal behavior of mass attracting mass!
