Re: Where is "here"?

Planck interval: "definition as the smallest possible unit of time in which we can meaningfully say that something has actually happened".

My point was and is: Reality doesn't necessarily conform with what primates can meaningfully say.

Re: Where is "here"?

The present is infinitesimal.(literally infinitely tiny) This statement is false. Time is not infinitely divisible and it does indeed have a smallest possible unit value which is very easily defined. It is the briefest possible interval in which we can meaningfully say that something has actually h...

Re: Where is "here"?

Where does subjective experience come into this? It would seem superfluous and would appear to fail your hardline Occam's Razor approach. I don't know how you can draw this conclusion. Although I make no metaphysical distinction between "life" and "non-life" I'm willing to accept the prosaic distin...

Re: Where is "here"?

if we have a infinite sequence of moments, it begs the question as to whether it's only an infinite sequence of information and energy or if there's something else in the mix I prefer to think of energy as an emergent form of information in much the same way that matter is but there is ABSOLUTELY s...

Re: Where is "here"?

Enjoyed both your posts. Much to agree with. Science can't possibly be used for macro explanations because it works from the bottom up. To depart from that approach is generally criticised as "unscientific", back to Stephen Hawking there. [quote=Obvious Leo"]The truth of our cosmos is the truth of t...

Re: Where is "here"?

Natural pain remedy comes to the rescue when all else fails. Leo, the strong nuclear force/gravity connection makes sense intuitively - forces of attraction manifesting differently at different scales - but the differences are counter-intuitive enough to add to the general strangeness at that level....

Re: Where is "here"?

The fact is that space is not empty but full of quantum particles. This is not a physical statement but a mathematical one, Greta, because you left a critically important adjective out of your statement. Space is full of VIRTUAL quantum particles and the meaning of "virtual" in physics is exactly t...

Re: Where is "here"?

Now there's a blast from the past, Greta, and spoken like a true flower child and refugee from the sixties. It's been a long while since the old "quantum foam" has been trotted out as a metaphor for the luminiferous aether. How thin can foam stretch before it vanishes into froth and bubble? I don't...

Re: Where is "here"?

... the differences in lensing effects between an observer on our moon and those observed by Zaphod's mum would be minuscule and require instruments of unimaginable precision to detect. Physicists are fond of using the word negligible for effects which their instrumentation can't detect because phy...

Re: Does reality really exist?

My feeling was that scientific literacy was an undervalued commodity at OPC, which was rather disappointing. There were quite a few members with some genuinely significant contributions to make on matters of science and more than a few with a keen interest in reading them. Like you, I've noticed th...

Re: Where is "here"?

The space between my most recent "lost place" and home is real, Relatively real, Greta. Your spaces are real relative to each other and relative only to the observer's perception of them. The spaces you observe on the streets of Sydney will look quite different to my mate on Betelgeuse V with his g...

Re: You are all fools.

Being a philosophy forum, it would seem prudent to examine the definition of "fool". Google tell us it's "a person who acts unwisely or imprudently; a silly person". A "person". Is foolishness purely the domain of humans, or of primates, mammals, vertebrates, of life per se? At what point does impru...

Re: Where is "here"?

Being directionally challenged, this is a question I have asked myself more times than I care to remember. I am even capable of getting lost using a GPS. There is something wrong with my brain :) Be that as it may, Leo, I need to take up the (fluffy padded) cudgels with you again about space. When I...

Re: Does reality really exist?

Rumours of my death have been grossly exaggerated, Greta, when I merely sought asylum from the religious zealots and the boot-heel of authority descending from the thought police protecting them. Life and work proceed in an orderly and meaningful fashion as always and the garden is once again becom...

Re: Does reality really exist?

In short, reality would seem to "really exist" but the nature of that reality is only partially known. Leo's apple (LTNS Leo!) exists and its "appleness" can be experienced or perceived in numerous ways. After all, you get apples the end of stalks of apple trees as opposed to plums, boulders or real...
