The problem with such a picture is that even those weak photons are visible from all directions.
Allow me this link to something I wrote almost a year ago on the same subject.

Then we must explain how I can remain invisible in such conditions. — Hachem
You are a real live textbook. So, let me take advantage of it. You reflect enough light back to me that I can see you, but not enough that you can see me. But my eyes could be anywhere. Light that enters my eyes could just as easily fall on any place of my face, or my whole body. And still, you cannot see me, while I would still be able to see you if the light illuminating you would become so weak as to only allow your silhouette to be visible.
Is that what you are saying? — Hachem
But tell me, when I am looking at you from my dark place, what is reaching my eyes, visible, or invisible light? — Hachem
I am glad you are back, let me understand it straight. If I am standing in darkness while you are standing somewhere illuminated, I cannot see you because you cannot see me? — Hachem
How come we can see illuminated objects while we are in a completely dark corner where no light reaches us? — Hachem
1. You might be right concerning the fact that with current telescopes we can see planets rotate. I honestly wouldn't know but I am willing to take your word for it.
Please do not forget that we are talking about the 17th century, and I do not think that the telescopes then, which were no better than cheap binoculars, would be capable of such a feast. — Hachem
Vagabond Spectre wrote: Parallax and resolution are not the same thing, and parallax has little or nothing to do with this experiment. Parallax is the apparent motion of objects due to changing perspectives of observation, which unless you can correct me has nothing to do with visible light after the emergence of Jupiter's moon following an eclipse. Resolution is not an issue either, as we do not need to see Jupiter's moon with any high degree of detail whatsoever, we just need to see when the light from it becomes visible after it's emergence from behind Jupiter.
Concerning the first part of this quote, this is as far as I can see an argument in my favor. We are capable of seeing objects as they really are, therefore with no delay. You reaffirm the idea by stating "bigger telescopes mean more resolution" which seems to indicate that we see distant objects as they are. I am curious as to how you reconcile the idea that telescopes give an accurate image of reality with the principle that it takes time for light to reach us (on that we agree), and that therefore the images we see represent an image of a moment in the past. All I am saying is that we are not looking at the past but at the world as it is now, and that is the puzzle we have to solve. — Hachem
Quote what you do not agree with and say why you do not agree with it instead of simply asking again and again for clarifications. — Hachem
The question is whether the differences in the times of eclipse and reappearance of the moon cannot be interpreted differently, without involving the idea that it takes time for light to travel through space. (1) We all know that when looking through the telescope at a planet like Jupiter, we do not see it rotating about its axis, or orbiting the sun. (2)We get each time a snapshot of a frozen moment in time, and the changes to the images we receive occur in jumps without any intermediate states. (3) This is understood as the effect of parallax, or more simply resolution. Because of the distance two points separated by relatively large distances will appear to our perception as one, and it takes time before we notice the difference between one position and another.
This is exactly the situation which Rømer is analyzing, but instead of understanding it as a case of parallax and resolution, he chooses a very specific approach. He considers the time it takes for astronomers to observe the disappearance or reappearance of Jupiter's moon as a fact that needs no further explanation. If we see the moon appearing at time t that is because the moon appeared at time t. And if we notice that when the earth is at another position, farther from Jupiter, and the moon appears or disappears at time t+x, then x must be caused by the longer distance between the earth and Jupiter. (4)This is much too easily discounting the fact that we only see immediately the differences between one view and another when we are very close to the object. (5)It is not surprising that Jupiter's moon seems to appear or disappear at a later time than when the earth is closer to Jupiter. The larger the distance between the earth and Jupiter, the more time it will take us to notice a difference between two consecutive moments. — Hachem
I do not think that. Therefore, I say that the theory of light cannot explain vision and certainly cannot explain the fact that when we look through a telescope the object is there where we see it, when we see it. The same way we look at somebody coming down the road, still a few hundred meters away from us, and we know it will take some time for him to reach us. Light theory as it is can easily explain this last example, but it breaks when it comes to distant objects and great distances. — Hachem
Right, but I disagreed. I'm not talking about poetry, necessarily. But I scarcely see why that's removed from philosophy. Why is poetry an exception? Because its just a subjective and aesthetic interpretation of being? — Marty
You don't. Since interpretation is ulimately bottomless. — Marty
Which is probably wrong considering that Kant, Hegel, Nietzsche, Heidegger, Plato, Aristotle - of which are ambiguous - have survived the longest. — Marty
The death of philosophy is when we're in agreement. — Marty
1. The pinhole lens has a Nikon fitting but is not made by Nikon. — Hachem
2. Your assumption of diffraction is not reasonable, Why should a collimated beam diffract when going through an empty opening? — Hachem
3. Even assuming diffraction, the question still remains of why there should be such differences between the different images on the basis of shutter speed alone. I would very much like to see some calculations that take the speed of light into consideration, and explain to me the differences. — Hachem
4. You are defending the theory or theories of light as they are taught. I have no problem with that. But referring to them is not enough. I will be very happy and obliged if you could show me where I went wrong, but appealing to authority is not enough. — Hachem
First, diffraction should not be a problem since we are talking about a 0.25mm aperture, with no lens. The different wavelengths are measured in nanometers. — Hachem
Concerning your objection about my Rømer analysis you are assuming that which I think he had no right to do. If you assume that you are seeing the moment when a moon appears from behind Jupiter you have already decided that the difference between the times of observations can only come because of the distance and the speed of light. I do not know how to make it any clearer, but this obviously, as least to me, the case of a circular argument. Your theory has to be right for it to be right. — Hachem
Your theory has to be right for it to be right. — Hachem
And honestly, really ambiguous thinkers and text are the ones that survive time and are the most interesting. I'm not one to buy into the idea that things need to be concise, clear, offer particular definitions. — Marty

Ohe of the standard techniques spread about by Big Energy is to cast doubt in just this way: oh yes, climate is changing, but we really don't know how much and because of what. It's standard FUD, fear uncertainty and doubt. And then all those micro-doubts get strewn around cyberspace and repeated by various people, like micro-plastics entering the food chain; legislation is diluted, green energy schemes stalled, and Big Energy wins the delay it wants.
Meanwhile..... — Wayfarer
We won't live to see the devastating effects of climate change, combined with the runaway effect that could be entailed by methane release. In most likelihood, we will learn to adapt to the new state of affairs provided by climate change, at the cost of hundreds of billions if not trillions to adapt our cities and current infrastructure and agriculture. — Posty McPostface
ah so youve seen sources showing that the range of free atmospheric methane can range from 12-100+ years? Or atleast that it has been known to last as little as 12- years? — XanderTheGrey
So if this ~50+ gigatons of methane in the East Siberian Arctic Self is released within say 10-20 years(which is stated as a possibility by Natalia Shakhova's team [10-80 years]) then it would kill and displace billions. But with the information you speak of makes it much less alarming given that it happens to be released gradually in smaller increments over say a 40-80 year period. — XanderTheGrey
You know what, i think I'm just going to make sure i have land and sanctuary in various parts of Canada, northern China, Russian, and New Zealand. — XanderTheGrey
↪VagabondSpectre
ah, no it seems i wasn't wrong at all, over a 20 year period methane is 86-150+ times more warming than CO2(carbon dioxide), and over a 100 year period; it is 28 times more warming than CO2.(so i was correct: it lasts over 100 years) This was stated by Stuart Scott within the first 15-20min of the press conference video i provided above in intial post.
I verified it here using wikipedia as my source. I tried a simple screenshot but phone is having storage problems, the but lifespan is verified within the very first praragraph of the article.

It lasts well over 100 years before decaying. — XanderTheGrey

First up, let's put my words in context, as the Daily Mail failed to do so. This 'rant' was a direct response to the violence of WHITE SUPREMACISTS in Charlottesville. It was not written this week.
Secondly, identifying that the success of the British Empire has been at the expense of the people of colour, is not something that should offend ANYONE. It is a fact. It happened. Slavery and colonialism, at the hands of white supremacy, played a huge part in shaping the United Kingdom and much of the west, into the super power that it is today.
Whether aware of it or not, in today's society the lighter your skin tone (people of colour included) the more social privileges you will be afforded. Whether that's access to housing, healthcare, employment or credit. A person's race and skin tone has a HUGE part to play in how they are treated by society as a whole, based on their proximity to whiteness.
When I stated that "all white people are racist", I was addressing that fact that western society as a whole, is a SYSTEM rooted in white supremacy - designed to benefit, prioritise and protect white people before anyone of any other race. Unknowingly, white people are SOCIALISED to be racist from birth onwards. It is not something genetic. No one is born racist.
We also live in a society where men are SOCIALISED to be sexist. Women are SOCIALISED to be submissive. Gay people are SOCIALISED to be ashamed of their sexuality due to heterosexual people's homophobia. Cisgender people are SOCIALISED to be transphobic. We do not need to be this way. We are not born this way and we can learn to reject it. We are just socially conditioned to think this way from an early age. With the right education, empathy and open mindedness we can unlearn these socialisations and live a life where we don't oppress others and see things from other people's points of view.
So when a transgender woman of colour, who has been selected to front up a big brand campaign to combat discrimination and lack of diversity in the beauty industry, speaks on her actual lived experience of being discriminated against because of her race and identifies the root of where that discrimination lies - white supremacy and systemic racism - that big brand cannot simply state that her thoughts are not "in line with the ethics of the brand".
If you truly want equality and diversity, you need to actively work to dismantle the source of what created this discrimination and division in the first place. You cannot just simply cash in because you've realised there's a hole in the market and that there is money to be made from people of colour who have darker skin tones.
The irony of all this is that L'Oréal Paris invited me to be part of a beauty campaign that 'stands for diversity'. The fact that up until very recently, there has been next to no mainstream brands offering makeup for black women and ethnic minorities, is in itself due to racism within the industry. Most big brands did not want to sell to black women. Most big brands did not want to acknowledge that there was a HUGE demographic that was being ignored. Because they did not believe that there was MONEY to be made in selling beauty products to ethnic minorities.
If L'Oreal truly wants to offer empowerment to underrepresented women, then they need to acknowledge THE REASON why these women are underrepresented within the industry in the first place. This reason is discrimination - an action which punches down from a place of social privilege. We need to talk about why women of colour were and still are discriminated against within the industry, not just see them as a source of revenue.
Racism may be a jagged pill to swallow, but I suggest you force it down quickly if you want to be part of the solution. Doing nothing, does nothing and solves nothing. Empowerment and inclusivity are not trends, these are people's lives and experiences. If brands are going to use empowerment as a tool to push product to people of colour, then the least they can do is actually work us to dismantle the source, not throw us under the bus when it comes to the crunch. At times like this, it becomes blindly obvious what is genuine allyship and what is performative.
I stand for tolerance and acceptance - but neither can be achieved if we are unwilling to discuss WHY intolerance and hate exist in the first place.
No but probabilistic wave functions and determined are. I can't believe the twisting and turning that you are willing to go through to get to your goal. Just forget the justification. You want your life to be fated? You believe in it deeply? Then just go for it. Nothing wrong with faith unless you make it wrong. — Rich
Zero precision. All measurements necessarily are approximate and incomplete. You really are in a hurry to get to your goal. — Rich
They are repeatable only to the extent that there always had to be an aspect of the experiment that is unknown. Heisenberg Principal. Hence the information is good enough for all practical purposes but necessarily unknown as far as completeness is concerned. — Rich
Determinists are always mixing up precision with good enough FAPP. It is the difference between the two that makes Determinism obsolete and Determinism good enough for the faithful. — Rich
Really, you want to make Quantum deterministic? Well the only way is to explore the Infinite Worlds of Everett's Mega-World Many Worlds. First you have to devise a experiment that crosses into the Infinite Worlds. I would say Occam's Razor would implore the Calvinist version of fate and Heaven. Far easier with the same results. — Rich
The only scientific equation that we have that speaks to causality is quantum theory. It is probabilistic. Nothing is repeatable. Some much, much less so than others. Every event is different and measurements are always approximate and that is only for those events that can actually be measured.
If you need enlightenment, go read Daniel Dennet. He is about as close to a prophet as you are going to find for the determinism religion. Now, I know what it means to talk to people of faith, so this is going to get us no where, so let's call it an end. Otherwise it gets silly. — Rich
You talk about brains, and neurons, and gravity, and circuitry sounds very scientific and creates a lot of gravitas, but at the end has nothing to do with determinism. — Rich
I sometimes fantasize about winning a megalottery and how I would spend it on promoting and experimenting with "good causes". Does that qualify me? — Jake Tarragon
It's actually rather amusing and ironic how Determinism is merely a religious off-shoot of Calvinism. Determinists adopted the faith in fate without the God. In God's stead, naturally, there is Natural Laws. — Rich
Yes, there is a mountain of evidence that if you damage a TV circuit, it will alter the picture not the TV studio where shows are actually produced. — Rich
The religion of course lies in the unshakable faith that all of this is fated — Rich
