If time dilation occurs when the velocity of an object approaches the speed of light and relativistic speeds, do objects experience time dilation when rotating at relativistic speeds? Aren't there pulsars or black holes rotating at relativistic speeds, how would someone's clock near the surface compare to someone a couple AU away from the star not rotating with the object?
On the surface of the body, you're moving, so you experience time dilation. Physically this is no different than orbiting The body. The clocks built into GPS satellites need to be constantly adjusted for this reason.
But the question how it works when the surface of a body rotates at relativistic speeds while the core is not moving breaks my brain.
Why is society so afraid of people purposefully altering their mental state? (In terms of cannabis, psychedelics, anything "mind-expanding.)
And even this isn't something that I've never seen asked, but aside from like Terence McKenna, I don't really know anyone who's interested in it, or even accept the question.
Edit this thread is a case in point. Not one single explanation, just people absolutely terrified out of their minds, parroting bad propaganda and even worse rhetoric. "I don't want my surgeon tripping when he's operating on me." And I don't want my surgeon drunk, and alcohol is legal, and I've never had the issue, because surgeons don't come to work drunk.
Genuinely, I'm tired of answering these "arguments" and no-one will accept how afraid they are, even when not a single soul can explain why.
because people in those states can act unpredictably and are thus unreliable. you don't want your surgeon to be tripping balls.
Pffftt these childish and stupid "arguments."
Your surgeon isn't drunk at work now, why would they be any less responsible with, say, LSD?
Only people who've never used drugs think this way, that once you do any illegal drug, you're instantly hooked, can't stop, 247 high and sucking cock for crack.
When you look at any science on the matter, those are simply asinine ideas which aren't supported by any of the evidence we have. Alcohol is clearly the most dangerous drug (well, arguably strong opiates, but it defined how you define dangerous or harmful, but Here's a handy ranking with a chart, comparing the relative harms of drugs.
We've got decades of data to show psychedelics aren't addictive, people only use them a few times a year when they're "actively" using them, they're far safer than alcohol, and have loads of benefits.
Cannabis is also extremely safe, and even when now it's at the point they're starting to admit the prohibition doesn't work, they're still pushing basically sixties propaganda like reefer madness.
We allow people to get wasted on booze. We allow people to beat other people up, as long as its voluntary. There's literally a sport (face slapping) where the object is to just hit the other person so hard you give them a concussion and render them unconscious. Getting voluntary brain damage is fine?
People can modify their bodies, jump out of planes, juggler chainsaws, spit fire, shoot guns for a hobby, celebrate with fireworks, swim in the Drake passage, but me, at home, doing LSD alone and watching great movies from the 60's is illegal.... becauseeeee?
In my opinion it’s because in the past human beings needed to be constantly working or assisting with a group in some capacity in order to ensure mutual survival for the group. Let’s say a village.
Activity which is not seen as being productive or could be construed as lazy has a stigma around it because it casts doubt on your ability to contribute to society.
Obviously none of this applies in the same way these days but there is a kind of primal conflation of intoxicants and laziness. Laziness is bad and so consuming intoxicants turns into a moral issue.
These attitudes are very deeply ingrained and although they can shift a bit as people become more liberal the deep suspicion remains.
Youre assuming there's no use in using intoxicants, but there very much are. Arguably the most important, in terms of larger humanity.
Those "deeply grained" attitudes are the product of 20th century propaganda.

In WWI it was completely normal to send your son/friend a package of morphine, cocaine and syringes.
And what I'm talking about is "mind-expanding" substances.
Alcohol literally depresses neural activity and makes it so you lose your coordination and eventually get sedated. It's the most "lazy" substance there is, yet none of these "deeply ingrained" attitudes concern it?
So no.
Were do viruses fit in the "tree of life"?
Outside. They don't have all characteristics necessary for the definition of "life" (they can't reproduce themselves), so they aren't classified as life-forms.
Probably as a stripped down bacteria.
Stop spamming please?
the topics seem good. but posting to two coms is kinda spammy. as opposed to asking in one, then collect answers before asking for further additional responses in another.
What are we going do if (and when) it turns out that economic growth is not compatible with environmental protection and yet a prerequisite for political freedom?
Sorry for the bummer of a question but to me the conundrum looks more obvious every day, I really want to know the answer, and yet (almost) nobody is talking about it.
Sustainable growth is popular but we are going to need to invest in unpalatable energy sources like nuclear power in order to power it. We also need to make sure recycling actually happens as opposed to local authorities shipping the materials overseas for “processing” (i.e. being dumped or burned).
Human populations tend to decline as an economy becomes more advanced and people are able to plan their families. We are already seeing population growth stagnating much more quickly than expected in countries like China. That will cause demographic challenges so we are going to need to rethink how we manage immigration so it can happen sustainably with public consent.
Lastly, increasing economic output doesn’t necessarily mean consuming more resources. If a country becomes more productive, by for example integrating a new technology, then you can increase output with the same or fewer resources.
I disagree that economic growth is a prerequisite for political freedom. I think that type of thinking has been perpetuated by capitalists to keep capital flowing. Communes and mutual aid don't have great or any economic growth but can allow for political freedoms that we don't even have now.
The counter-argument is that communes are populated by an unusual variety of human being, hence their rarity, and that most people are motivated by less disciplined human goals such as status and material accumulation.
Nate Hagens talking with Daniel Schmachtenberger.
Youtube it.
Interesting, will do. I do know of the host's dark take on such matters.
In terms of more mainstream pundits it just really bothers me how many so many of them are obviously intelligent and well-meaning yet incapable of breaking out of the mental straitjacket of orthodox economics, despite all the evidence that its usefulness has run its course.

The fun answer is kill
If you had a microscopic object that took up the smallest amount of space physically possible, what shape is it? What shape is a pixel/grain of space?
I think it would not have a shape, or would rather be a zero dimensional point. For it to be any shape, it would have to have features, but you've already defined this as the fundamentally smallest 'thing' so it can't have any features smaller than itself. But you could also probably convince me that it's a sphere. I'm not sure if mathematicians consider a sphere of infinitesimal radius to still be a sphere or not, but treating it as infinitesimal kinda makes sense to me even if it's actually finitely small (the Planck length?)
A more interesting question to me is, assuming positions in space are discrete, which I'm not sure follows from saying there's a smallest possible object, how are those 'voxels' arranged? I don't think that's necessarily equivalent to asking what the shape of the smallest object would be. Pixels on a screen are in a rectangular grid, but the actual elements are circles in some types of screens.
There are a number of shapes besides cubes that can fill 3D space, but do the voxels even have to all be the same shape? Are we even looking for a 3D tiling, or could it be 4D in spacetime, or even higher dimension if it turns out the universe has more than 4 dimensions? Does it have to tile at all, or could it be entirely irregular while still being discrete? Is there any conceivable experiment that could prove any of these things, or is it unknowable?
What you're talking about sounds similar to the Planck length to me. I'm not a string theorist, but my understanding is it is well defined in normal 4D spacetime (where Planck time would be the time it takes a photon to travel one Planck length). Planck length is based only on universal constants (Planck's constant, speed of light, and the gravitational constant), and so any "thing" smaller than that is unphysical.
I think the interesting question is how do we get continuous experiences, measurements, and observations from a spacetime that is fundamentally quantized.
