So, basically, we don't know that much on anything besides understanding it's really complex and difficult to figure out.

To quote someone a lot wiser than myself:

It's a shame stupid people carry themselves through life full of certainty while the wise ones suffer a life of doubt.

[–] [email protected] 6 points 10 months ago

That's a paraphrase of a famous Bertrand Russell quote. The original is as follows; "The trouble with the world is that the stupid are cocksure and the intelligent are full of doubt."

There's also the William Butler Yeats corollary; "The best lack all conviction, while the worst are full of passionate intensity."

Not really. It's all about models - we have for normal stuff, but it breaks apart in extreme situations

So clearly the model is fundamentally wrong... Which is pretty cool, because it means FTL travel, antigravity, or travel between dimensions could be possible

But we know now normal shit acts - we have models that work perfectly for 99% of all situations, and we're probably not going to stop using them. We understand what happens when you throw an object, and it's a basic equation up until like mock-2 or 3, where our models stop working and we have to switch them out completely

Can you build a model that works for both? Absolutely. It'll be closer to the truth even. But it'll be way more complicated for nearly all practical, human scale situations

At the end of the day, a model that describes reality exactly is almost useless... Without simplifications to ignore everything not relevant, just trying shit live would be easier than calculating the prediction

Not really, OP's image is somewhat misleading. The truth is that we're constantly trying to improve our understanding of physics and some theories are not completely correct but they often provide a way for future scientists to dig deeper and figure it out. Then with new knowledge, new hypothesis can be suggested creating a gateway to deeper understanding of some concepts further down the timeline.

Yes, yes, I'm quite sure, it's 42!

[–] [email protected] 8 points 11 months ago (1 children)

The question is if it will still be 42 when we look away.

I highly recommend the book "We Have No Idea" by Jorge Cham and Daniel Whitesom. Great explanations of what we know about the universe (with hilarious comic illustrations) and a profound message of just how much we don't know.

[–] Potatos_are_not_friends 6 points 11 months ago* (last edited 11 months ago) (1 children)

Thanks for this recommendation! I love books that show me how little I truly know about anything.

Like all of Randall Monroe's books (xckd guy).

Any more book recommendations?

Copernicus deserves a mention. Galileo's problems resulted (in part) from him being a proponent of Copernicism after the church had declared it heresy.

Heliocentrism was suggested by Copernicus and Galileo built on that, including developing physics to the point where he couldn't believe otherwise.

[–] [email protected] 14 points 10 months ago (5 children)

The heliocentric models predicted the orbits worse than epicyclic geocentric ones and that is the reason Galileo was told to shut up, the court transcript is like 99% science and then a single subordinate clause saying "it also contradicts the bible".

Galileo insisted on circular orbits which was his downfall, ironically "because circles are perfect and god would furnish the universe perfect": That kind of religious language while also being worse science than what was already established did him in. Kepler, based on Brahe's data, was the first one to get a heliocentric model right and more accurate than the epicyclic ones.

Also earth doesn't revolve around the sun. If anything both revolve around their shared centre of gravity but really it's a matter of your frame of reference. Paraphrasing Archimedes: Give me a fixed point in the universe and I will move all your models.

And gravitational stuff. We kinda know it does it, but not how to do anything about it.

[–] arken 10 points 10 months ago (2 children)

Surely that's "heavy stuff"?

[–] Iron_Lynx 7 points 10 months ago (1 children)

And maybe also "big stuff". I suppose those two overlap quite a lot?

I can't wrap my head around time being anything other than the measurement of movement, and until someone can prove otherwise, that's where I'll be.

[–] DeathbringerThoctar 12 points 11 months ago (3 children)

I'm going to take your definition just a step further and say it's a measurement of causality specifically.

[–] brenticus 11 points 11 months ago (7 children)

A definition I saw recently that I like is that time is the direction of entropy. You follow time one direction and you get the big bang where everything is chaotic and happening, and in the other direction you get the heat death of the universe, where everything has settled into a base state and nothing's happening.

I think we got the fast stuff under control (special relativity), when you mix it it with like small stuff (quantum field theory), and I guess big stuff (general relativity), it is also OK, but mixing it with anything more than that causes a problem.

[–] MightyGalhupo 10 points 10 months ago

This is from science abridged beyond the point of usefulness right? I have that book.

Edit: yes it is

[–] EmoBean 8 points 11 months ago

Shit's on fire, yo. But does that fire only produce positive vibes or are there like 90% bad vibes, you know, bro?
