@97 Eleven Then do extrapolate.

The metric tensor cannot be quantised meaning the einstein-hilbert field equations can't be quantised. And any attempt at peturbative theory coupled with gravity fails and results in a non-renormalizable situation.

I'm sorry, that's applicable to general relativity, not gravity. Because guess what, general relativity is a predictive model for macroscopic systems.

You ask for evidence, what's the point in providing any of the mountains of evidence when your argument against it is "don't trust your senses or anybody of a reputable source, trust me though."

🤔

Your conclusion was derived from what exactly?

Every flat earthers argument against celestial bodies in motion, ever.

Except that this isn't exactly a standard FE argument

It always boils down to the same stuff though

So how does "spacetime curvature" have physical effects between masses? As in something tangible beyond the imaginations of theoretical physicists?
I'd like to know

i jsut dont think its smart to judge the shape of earth by the shape of other celestial bodies or their movements

its all a theory astral

what do u wanna see an experiment of spacetime curvature ? havent u seen the one with the blue sheet and they rolld the balls around on it. what more do u need

i hear u though im not buying that crazy theory either

u cant tell me spacetime curves then roll balls on a sheet and say there it is

we should brainstorm on an experiment to prove or disprove the curve though. doesnt everyone wanna know the truth and end this debate lol

Space-time is a construct, yet it can supposedly warp and have physical effects on masses.
This is quite an extraordinary claim that would need some defined tangible aspect, and not just existing in the imagination of people who work on these theories. Science is what we need, establishing cause and effect relation

i hear u astral

its a bold claim

that is gravity for ya though

when the roll the balls on the sheet thats 2d wouldnt the fabric of space time have to be bending in all directions

Freefall is an observable fact, and it follows an observable relationship, like acceleration, terminal velocity, buoyancy, etc. No theory need for it.
But if you are to propose a hypothesis like this, it needs to be quantified, tangible, and able to be manipulated, so it can be tested and also be falsifiable

dude

why do u sound like a flat earther today

Lol

yesterday i debated u for 3 hours on if the water at the ocean appears to be above ur feet lol

Of course it appears that way. Everyone will admit that

no astral doesnt

But it's actually level

i literally debated him on that one thing for hours last night

What does "sound like a flat earther" mean? I didn't know they sounded a certain way

ur going against the mainstream wanting evidence and proof

sound like a flat earther lol

my bad wasnt tryin to insult u

That is by no means exclusive to "flat earth", so I'm not sure what you mean there

well do u think the curvature of space time is real if the earth is flat

I am not convinced "curvature of spacetime" can exist beyond imagination, since spacetime is merely a construct as far as we are concerned

i agree with you

no need for us to debate tonight thank god

lol
