Do atoms exist?

[bhavv]

Just like pythagoras, it's a theory but it's widely accepted to be true because it can't be proven wrong or right (at this time).

Scientific Theories are proven observations with repeatable, supportive, testable hypothesis, and should be considered factually correct until / unless they are ever proven wrong.

They arent 'theories' by the dictionary definition of the word. The dictionary definition for 'theory' is actually a hypothesis in Science.

Define : Atom.
Define : Exist.
Define : Define.

Then dissapear up your own hole.

I hate all this pointless brain noodling.

But if you do this then you just invalidate 100% of Philosophy

To add to this,

Theory's are also proven by having a testable predictive value.

You can use a theory to improve an invention, predict the outcome to a series of events.

The use of the theory in practical application is the main validation of it (to at least prove it has predictive value).

We know atoms exist because not only have we observed them, but we are able to utilise the science behind it for a vast array of practical inventions, processes & further studies.

This is the main difference between the scientific theory of evolution & the theory of creation.

We can estimate the physical characteristics/traits of a creature based off our understandings of how evolution works in a given environment, we can see genetic links & explain how changes may occur in the future.

The theory of spiritual creation has no predictive of practical value, as you can't do anything with a theory that utilises magic.

I was going to do the density of a black hole, but when i went googling for figures all i found was some articles saying how some black holes may have a similar density to that of water

Have to admit, I've not actually come across this before.

Doing a quick scan they refer to the average density. i.e. Volume as defined by event horizon. That's just the sphere of gravitational influence by the object at the centre (of a 'black hole'). So more mass -> greater gravitational reach -> more volume. The mass is compressed into this 'object', a singularity, within the centre of this sphere.

Adding more mass must increase the volume disproportionately to the amount of mass being added resulting in seemingly lower density. Whereas at the centre, it's probably more solid than..well anything.

It makes sense but I'm probably wrong, it's probably relativistic effects slowing down the mass so much it never actually reaches the centre of a black hole so that average density = actual density
