What is the speed of light in the reference frame of the photon?
StringJunky replied to pavelcherepan's topic in Relativity
I think you mean Strange Nicholas. -
Yes. With my little knowledge I'm also inclined to think it has a property in common with the other three and they mutually emerged via some phenomenological path from a more unified source. Still, as you say, the cognitive leap is still large and gravity is smooth whereas the other three are not ...a very big bridge to reconcile I would imagine for those that are trying to. Is this the primary problem, that it won't chop into pieces?

I wonder what the ratio of land area required for nuclear and solar plants respectively is for producing equivalent output.
-
AFAIK the photon frame is not a valid frame.

...and this is as good as it can be. 'Truth' is for philosophy, metaphysics and religion. If a scientist said "this is true" then he has closed his mind to possible future falsification in the light of new evidence. Maintaining persistent doubt as a matter of professional habit is what stops scientists becoming complacent. Time is defined as what clocks measure ...it's just a parameter. You don't see people cogitating about 'length' do you?

Light does not need a medium. The electric field generates a magnetic field and vice versa oscillating orthogonal to each other ..,it is a discrete phenomenon AFAIK.

Theories on possibilities may have ruined my life
StringJunky replied to Tailspin's topic in Mathematics
If a book had to be a pre-defined length then the creative possibilities are finite but they are not so the permutations are endless. The number of words may be finite on any given day but new words or meanings to existing ones are being added thereafter ....language - especially English - is not in stasis. -
What it means is that I don't have a clue because if those two parameters were absent there is no framework to place things in to make sense of their position or order. Yes it could have happened all at once but taken an 'eternity' to do so! Sorry about the oymoron but we can't be sensible about this because two mainstays in this scenario are missing i.e. space and time.
-
Pre-BB, things might not have happened in the familiar temporally/spatially sequential fashion as they did and do post-BB... these two parameters may not have even emerged before then yet the universe existed. This way you can have an eternal universe that didn't 'pop' into existence and yet the clock started at a particular moment in its evolution.
-
I sense more than a hint of a Galilean complex going on with you here... you alone against the establishment. I don't have a horse in this race and am really quite ignorant of the subject matter so don't have an opinion either way but this does stick out to me.

Does Humour Have a Place on SFN?
StringJunky replied to Ophiolite's topic in Suggestions, Comments and Support
I'd rather have the odd out-of-place humour than no humour at all. Excessive formality would make the site stifling. -
You can have empirically derived faith based on past experience of that object or person. For example; That person did a good deal with me the last dozen times so the chances of a positive outcome are good the next time.

Well, he decided that it wasn't going to be given on a plate. How can you know happiness without experiencing it's opposite ...one needs a reference.
-
I don't think a hole exists per se. It is an abstract concept like and probably related to the idea of 'nothing' ...it is a particular state of absence of something.

What about using a ball-bearing as the golf ball and putting an elastic surface on the golf club face of appropriate stiffness and depth such that the elastic surface doesn't fully compress on full contact?. There should be more inertia in the travelling ball to punch through the air resistance.and hence gain more distance.
-
What's the point of creating a universe and already knowing the story that will unfold within it? Boring. Put some variables in it and you've got a story you don't know the ending to. The essence of religion it seems is about the testing of commitment so it makes sense to me for God to make the universe autonomous and design it with that remit. You can't know happiness without knowing unhappiness and vice versa so we need awareness of both states to appreciate the positive state.

I suppose the overarching improvement in adopting a vegetarian mindset is that one is consciously/proactively trying to adopt a healthier lifestyle which has beneficial spinoffs like reducing alcohol consumption. cutting smoking, more exercise and reducing saturated food intake etc. Regardless of whether there is confounding factors in determining the healthiness of a vegetarian diet specifically, vegetarians do generally live longer.because of all the other personal changes that go with it it seems.
-
Yes, there's nothing in between.

I think it means something which has no discrete divisions i.e seamless
