>What are newtons laws?!?!? They explain the experiments, but what the hell does""""""a gravitational force """"" mean

we can never truly understand what these forces or particles or anything fundamental in the universe "IS"
We can make predictions and make experients, but we can never truly understand what those ""mean""/represent

Why is every single one of these brainlet threads "debunkable" by xkcd or smbc? Why can't these people just read smbc or xkcd and not waste space on /sci/?

The rubber sheet analogy is terrible, and it inevitably leads to the nonsense in the OP.

First read this:

Then read this:

Then watch this short animation:

"speed of light" is not a thing that can be moved. But if you're talking about space itself, then sure.

At some point we just run into pic related.

That analogy is awful.

It's more like this.

Photons are quantized excitations of the electromagnetic field.

That sounds short, but I recognize it's not really a full explanation. The full explanation is long and is all math. Pic related for what the problem is here.

Whatever you're thinking is probably mathematically equivalent. No difference. Besides, what you're referring to is just a crude toy concept of what GR says.

Pic painfully related.

The rock does fit. It's clearly doing something different in each case (accelerating or not), depending on the physical arrangement of the experiment (the presence or absence of a hand).

>Particles exhibit characteristics of waves.
>Waves exhibit characteristics of particles.

More like, classical particles and classical waves are both limited analogies for reality.

This.

These, unfortunately.

If you don't understand it and are so interested in it, then start from scratch and study QM and everything else needed to understand it. If you don't understand it, then at least be humble and say "I don't know much about it, so I'll refrain from taking positions".
