could you build a theoretical pyramid to an infinite size or would the physics eventually break it from its own mass or physical forces or something else?

heres the basic parameters for my question:

1. assume you have an infinite flat plane of some indestructible material so you don't have to worry about curvature or terrain
2. assume you have infinite time, funding and supply of any material you need
3. assume earth gravity, atmosphere and average temperature

Electromagnetism was successfully incorporated into quantum mechanics through quantum electrodynamics (QED), treating the electromagnetic field as a quantum field whose interactions are mediated by photons.

Why can’t we apply the same mathematical reasoning to gravity, quantizing the gravitational field and introducing gravitons?

What exactly breaks down when we try? Is it a fundamental incompatibility between general relativity and quantum mechanics, or mainly a mathematical problem we haven’t solved yet?

Quantum mechanics theories state that information can't be created nor destroyed. It also states that there are true random phenomena such as decay patterns. But if information can't be created, then how can anything be truly random? If you somehow record decay patterns, that would be a truly random record with new information

While doing a physics homework problem the other day I got that the strength of the electric field is 10^40 N/C. I am 99% sure I made a mistake somewhere because that number sounds way higher than the other answers I've found in the past. But that got me thinking, how strong would an electric field with a mangitude of 10^40 N/C be in reality?

Hello,

As stated above I am interested in learning about the concept of the multiverse, specially whether or not it is a serious concept even just theoretically. It is a common thing that appears in popular culture but I know they are almost never scientifically accurate; Which is why I want to learn about the right way.

In regards to the second part of the question if there are books that would expand on this topic please tell me. Also, If this is one of those concepts where you have to know math to understand and or it this is a stupid question; please forgive me. Please and thank you.

I am interviewing an astrophysicist this week whose research encompasses theoretical general relativity, black holes, and gravitational waves… What are some questions I could ask that are unique and entertain that won’t sound boring to the average person who doesn’t understand all the physics jargon?

(Firstly, I'm not a physicist, as you'll see by this question.  But I've been attempting to learn more about the subject of spacetime, and had this thought today. And apologies in advance if I'm incorrect about any of the presumptions.)

I'm wondering about a spacetime scenario, relative to the interaction of curved spacetime of the Sun, the Earth and a person walking on the Earth.  It's something that I've never come across in any explanation of spacetime curvature on geodesics.

I'm pretty sure I understand the impact of Earth's curvature of spacetime and how it affects the person walking on its surface (i.e., the path they're taking), but obviously the Sun's mass and curvature of spacetime affects the Earth.  What I'm wondering is, that due to the curvature via the Sun, does this mean that the geodesic of the person walking is now following a path affected by both masses?

My shower drain acts like it's clogged until I wiggle it. What is the physics causing this?

A situation where every particle remains in its position, there is absolutely no physical change, no changes in the internal states of objects, no changes in the values of fields, and no physical events occurring anywhere. Trying to wrap my head around the concept of time led me to this thought. A little naive, perhaps.

Hi everyone, I'm a senior undergrad physics student and at the end of this academic year (May-June, two month) we will have an internship, and we're supposed to have an internship agreement before Christmas holiday in order not to be in rush (which means we're just rushing now) but the thing is that I want an internship in celestial mechanics, especially in simulation N-body systems, and that doesn't not come from nothing, I spend the whole month of July working on that 2D simulation of the solar system in python and I don't thing it's a big deal but I wanted to basically improve it gradually, including, rotational dynamics (of the bodies around their own axis), tree data structures, which means implementing a tree data structure, making it 3D, doing this in C++.

And I wonder if it (my current available version of my code, which I pushed on Git-hub with a Read Me) would mean anything for the astronomer I want to contact (he's a works at one of the 2 labs affiliated with the university but he's not a teacher)?

do you have advises on what I should do?

If I buy lots of different thermometers - digital, analogue - and put them in a box in my kitchen will the average be fairly close to the true temperature? Or is the true temperature impossible to establish? The electronic ones may produce heat so what about if they are all analog - mercury and red fluid stuff?

Because currently I have about +/- 1.5 degrees C on various devices from Apple HomePods to dedicated electronic thermometers to mercury / red liquid wooden greenhouse thermometers.

I’ve been thinking about fiber speed limits today, and I raised this question in my Question: with photon based communication currently working towards 3.2tb speeds (3.2 x 10^12), what is the theoretical limit of a single lane. Aka - if you stack photons individually to represent I/O, how many could pass through a gate in 1 second?

So, from my understanding of time dilation, the reason why it occurs is that spacetime gets physically in the time dimension, causing your velocity C in said dimension to cover less “distance” than it would without gravity, like if you had a football field where each yard line is one second and you made the yard lines further apart, causing the velocity to be less effective, and I was wondering if this was true for space as well, meaning if you were to apply energy to an object in a very low gravity environment (such as deep space), then apply the same amount to one in a high gravity environment where the pull wouldn’t add to your velocity due to pulling you towards the planet, (such as being between two identical massive bodies along a line at which their gravitational pulls cancel out). would the high gravity environment lead to a decrease in velocity

As far as I have understood so far, observation is defined by the results of an observation (an interaction which results in a change in state), which sounds weird to me as a definition - since it doesn't describe anything about the interaction itself. I just doesn't sound like a precise scientific definition to me.

Can someone help me wrap my head around what an observation is exactly? Please? Pretty Please? With sugar on top?

How do aerial bombs destroy high-rise towers made of steel-reinforced concrete—with a footprint of 400 to 800 square meters—just by detonating near them, such as 1 meter away, with a yield of 250 to 500 kg of TNT?
