We are going to try and factor a RSA number that has yet been factored. No guarantees it will work. My estimate by graphing is that if we start at 4.0 X 10^37 and increase in value using brute force to divide into PNP, we may be rewarded with an answer. I understand it is still many values but at least we have a starting point. I also understand that if we are unsuccessful, we may be aided by finding the error of the factoring equation. Also graphs can be deceiving. If it is wrong starting point, it could be the graph is right, but the view of the graph is wrong.

In addition, I dislike subtraction so much I'll stop at nothing to avoid negative numbers.

What process are you using to take samples and confirm the increased adrenaline in a lab? My intuition is this would be better described as a subtle form of anxiety attack

Hi, I'm a new member, In this topic, we are going to talk about Black Hole Stars. Black Hole Stars were formed by Dark Matter Halo, which creates very massive stars that are million times the mass of the sun. They were so big that even after their birth, more and more gas piled on the newborn star. After a while, the core gets hotter and hotter but the external force crushes the core, making the core a Black Hole! A massive explosion happens but the star is so big that it resists even a supernova! The Black Hole is a few tens of kilometers inside a star, which is the size of the solar system.

Very far from what? There are galaxies in every direction. It cannot be very far from everything. However far is "very far". Yeah. r is the distance, and m is the mass, and q is the charge, and I is yours truly. Distance between what and what? Again, there are galaxies in every direction. And galactic halos in every direction. How does that reproduce the velocity curves? You are mixing and mis-matching the expansion of the universe with the v(r) law for galaxies from the centre outwards. Very different things. One goes by the name of dark energy. The other, dark matter. Different names for very good reasons. The galaxy rotation curves are rotations of stars around the respective galactic centres. Expansion of the universe is about galaxies getting away from each other. You're not making any sense. At least about the universe we observe.

My idea is that there is a colossal black hole that is very far (out of the range of all the most powerful telescopes) but has a huge mass that is billion times the sum of the masses of all the astronomical objects that we have seen until now, including all the galaxies, supermassive black holes and supernovae. It is so massive that also dividing its mass by r2 (where r is the distance) its gravity influences all the astronomical objects that we have seen until now. All these astronomical objects are punctiform with respect to the colossal black hole and they have a spiral motion towards the colossal black hole.

There is a fascinating aspect of human physiology that I've personally experienced: the ability to initiate sensations akin to an adrenaline rush at will, without the need for external triggers. Through personal exploration and discussions with medical professionals, it's become apparent that this ability involves a deliberate activation of specific musculature, possibly connected to the autonomic nervous system. This activation induces a sympathetic nervous system response, leading to the release of adrenaline and subsequent physiological changes such as increased heart rate and pupil dilation. What sets this phenomenon apart is its self-initiated nature, devoid of any external triggers. While not extensively discussed in scientific literature, I believe it holds significant potential for further exploration. Have any of you encountered similar self-initiated physiological responses or come across relevant research in this area? I'm eager to hear your thoughts and engage in discussions about this intriguing aspect of human physiology. I’ve had this happen my whole life I don’t discuss it because rarely anyone can relate I can start it in my head then thighs and then torso area I’ll add I can hold it for subs four seconds due to intensity Van anyone relate or maybe she’d some light on the topic? Thank you ps-no, I’m not CRAZY nor have ASMR

Rotation driven by a supermassive BH would lead to Kepler curve which does not match the galaxy curves. Secondly due to the 1/r2 relation of reducing gravitational strength per mass term the strength of gravity would fall off to effectively zero influence Long before reaching the outer galaxy region.

I quote the Wikipedia page https://en.wikipedia.org/wiki/Cosmic_microwave_background: "With the increasingly precise data provided by WMAP, there have been a number of claims that the CMB exhibits anomalies, such as very large scale anisotropies, anomalous alignments, and non-Gaussian distributions."

Hello. How does your idea take into account that observations show the CMB is remarkably uniform across the sky? The observations shows that the universe is homogeneous and isotropic on large scales. How is this uniformity consistent with your description of the universe?

And it can only multiply.

Hello! I'm new to this forum. I have an idea that could be the simplest explanation of the accelerating expansion of the universe. I've described my idea in my blog https://max70blog.blogspot.com/ and I report it here below. I would like to know your opinions on this idea. The simplest cause of the accelerating expansion of the universe I have an idea that could be the simplest explanation of the accelerating expansion of the universe. I'm surprised that I've never found such a simple explanation anywhere on the Internet. My idea is born from the fact that in the center of almost all the galaxies there is a super massive black hole. The objects near the black hole have a spiral motion towards the center of the black hole. This may be seen for example in the video in the Wikipedia page of the galaxy rotation curve. Then in the universe we have: satellites that rotate around a planet planets that rotate around a star stars that rotate around a super massive black hole in the center of a galaxy Therefore in the universe we have a scheme: masses that rotate around larger masses. My idea is to generalize this scheme and to apply this scheme on a larger scale, and then on a even larger scale and so on. The first step of my idea is that the Milky Way and all the astronomical objects that we have observed until now are part of a Colossal Galaxy Cluster around a Colossal Black Hole. The following Figure 1 shows the first step of my idea: Figure 1 MW, that is the yellow dot, is the Milky Way. CBH, that is the black circle in the center of the figure, is a Colossal Black Hole. CGC, that is the circle filled with orange dots, is a Colossal Galaxy Cluster. The galaxies and the other objects in the CGC have a spiral motion towards the CBH. Until now, we have observed only a little part of the CGC, because the range of all the telescopes is limited. This is shown in the following Figure 2: Figure 2 CBH, that is the black circle in the center of the figure, is a Colossal Black Hole. CGC, that is the circle filled with orange dots, is a Colossal Galaxy Cluster. E, that is the cyan dot, is the Earth. OP, that is the area filled with yellow dots around the Earth, is the Observed Part of the universe, that is the part of the universe that we have observed until now. OP is only a little part of the CGC and of the observable universe. Note that the CBH has a mass that is many billion times the mass of the OP. Someone could say that it's absurd to think to a black hole having such a large mass. Actually, the black hole cosmology, that argues that all the observable universe is inside a black hole, has been studied for many years. My idea is simpler: the portion of the universe that we have observed until now (OP) is part of a colossal galaxy cluster (CGC) that rotate outside of a colossal black hole (CBH). This idea could explain the accelerating expansion of the universe, that was discovered calculating, from the redshift, the acceleration of some supernovae. This has been then confirmed by the baryon acoustic oscillations. All the objects in the CGC, and therefore in the OP, have a spiral motion towards the CBH. The objects closest to the CBH have accelerations greater than the more distant objects. This is shown in the following Figure 3: Figure 3 E is the Earth, while S1 and S2 are two supernovae. aE, a1 and a2 are their respective accelerations. Now consider the following Figure 4, that shows the accelerations relative to the Earth, that are obtained subtracting aE from the absolute accelerations: Figure 4 ra1 and ra2 are the accelerations relative to the Earth. Therefore we see the supernovae accelerating away from the Earth. Actually, we haven't seen with the telescopes the accelerating expansion of the universe, but rather the accelerating expansion of the OP, that is the part of the universe that we have observed until now. In effect, all the evidences of the accelerating expansion proof only the accelerating expansion of the OP and not of the entire universe. Usually, the cause of the accelerating expansion of the universe is considered the dark energy, that is related to a posive cosmological constant and to the vacuum energy. However, the cosmological constant problem is still unresolved: the observed value of the vacuum energy is many orders of magnitude lower than the theoretical value of zero-point energy. Other alternative causes of the accelerating expansion of the universe have been proposed, such as the quintessence, the massive gravity and the multiverse. In my theory, the accelerating expansion of the OP is simply caused by the gravity of the CBH. My theory is simpler than other theories and therefore, for the Occam's razor, preferable. Note also that some observations that are currently considered to be caused by the dark matter could be explained by the gravity of the CBH. A less known theory that tries to explain the accelerating expansion of the universe is the VACIS, that argues that the universe is contracting in a spiral. My idea is simpler: the objects in the CGC and in the OP have a spiral motion towards the CBH. In addition, how I will explain later, the CGC is probably only a little part of the universe. However, the considerations of the VACIS on the motion of the galaxies could help to confirm my theory. I remark that until now I've exposed only the first step of my idea. Now we could apply the same scheme on a larger scale. We could think that there are billions of Colossal Galaxy Clusters, that form a Super Colossal Galaxy Cluster around a Super Colossal Black Hole. The objects in the Super Colossal Galaxy Cluster have a spiral motion towards the Super Colossal Black Hole. This is shown in the following Figure 5: Figure 5 SCGC, that is the circle filled with orange dots, is the Super Colossal Galaxy Cluster. SCBH, that is the black circle in the center of the figure, is the Super Colossal Black Hole. SCGC is a cluster of CGCs (Colossal Galaxy Clusters) that have a spiral motion towards the SCBH. The yellow dot in the figure is the CGC that contains the Milky Way and the Earth. Then we could apply the same scheme on a even larger scale and so on. We could define by induction: Super0 Colossal = Colossal Super1 Colossal = Super Colossal Super2 Colossal = Super Super Colossal ... SuperN Colossal = Super SuperN-1 Colossal SuperN+1 Colossal = Super SuperN Colossal The following Figure 6 shows the generic case for N positive integer (greater than 0): Figure 6 SNCGC, that is the circle filled with orange dots, is the SuperN Colossal Galaxy Cluster. SNCBH, that is the black circle in the center of the figure, is the SuperN Colossal Black Hole. SNCGC is a cluster of SN-1CGCs (SuperN-1 Colossal Galaxy Clusters) that have a spiral motion towards the SNCBH. The yellow dot in the figure is the SN-1CGC that contains the Milky Way and the Earth. Note that the case N = 0 is shown in the previous Figure 1 while the case N = 1 is shown in the previous Figure 5. An open problem is whether N is illimited or limited and which is the superior limit of N. Maybe N is illimited and the universe is infinite and in the universe there are black holes as big as we want.

Look at it piece by piece. You buy hydro from the utility at $10/kw/hr whenever you need it. Your neighbour buys hydro from the same utility at $10/kw/hr whenever he needs it. You sell excess electricity to the utility at $7.50. Your neighbour may or may not sell excess electricity to the utility for $7.50. All separate transactions. The utility company has overhead costs for infrastructure, maintenance and repair, vehicles, personnel, administration and billing, taxes etc. So a 75% share for the supplier sound like a good deal. You have very little overhead, once the infrastructure is in place, but you may have to pay income tax on the money you receive from the utility. But then the charges can get a little whiffy: They may tack onto your bill a 'delivery charge', a surcharge, equipment rental, retirement of their debt or whatever extras. I don't know where you are, but in Ontario, the extras are considerably more than what we pay for the electricity we use. (Our solar array doesn't generate excess; it's just enough for our needs, except in winter and bad weather, when we fall back on the grid.)

A handsome and muscular man walks into a bar, opens up his backpack, and sets out on the counter a tiny man and a miniature piano of compatible size. The tiny man begins to play, with great skill. That's amazing, says the bartender. Where did you find him? A genie in an old bottle gave him to me, says the man. I had three wishes. The first two were good looks and immortality, and those were provided - today is my 157th birthday. The man sips his beer and looks sadly over at his tiny companion. Unfortunately, says the man, the genie didn't hear me clearly on the third wish so instead of my actual request he gave me a 12 inch pianist.

Thanks. The $5.00 would be the credit of $7.50 they give me when I consume back from the utility minus the $2.50 the utility collected from my neighbors that consumed the power I generated earlier. The thing works as a reservoir. My generated energy is "stored" by the utility until there is no sunlight and I use again energy from their grid. But did they already billed my neighbors $2.50 ? And will credit me for $7.50 Is the utility crediting me $7.50 really costing the utility $7.50 to issue the credit ? Edited... Am asking just by the financial smell of it. Something is behind scenes I cannot see. Suspect it is a similar 'effect' of the one on post ---> https://www.scienceforums.net/topic/62792-question-in-finances/#comment-649137

Well first, Franklin's RoT is 50/500, just to get our decimals in the right place, and it is highly dependent on species reproductive rate, habitat needs, average number of harmful recessive alleles (it's around 5 in humans, IIRC) and probability of disruptions to the ecosystem. Also, an artificial one, i.e. a zoo or wildlife preserve in an O'Neill colony or what have you, would have different requirements than a natural ecosystem where the goal is to save from extinction. Franklin et al were trying to make a RoT for wildlife conservation in natural settings, especially ones under siege from human depredations. So the space habitats you envision might work with a lower number. The 50 is a minimum in a locality to reduce deleterious inbreeding between close relatives, the 500 is the total number of that species in the entire habitat needed to reduce negative effects (low diversity) of genetic drift and maintain a healthy adaptive population. Again Franklin's model is very dependent on species and habitat and what controls are in place (a space habitat, I would imagine, would have a lot). I'd have to think a bit on how well the 500 popsicles scenario, with AI injections (each generation, most likely) would work out. I guess it could play out like, e.g. small bands of humans (50 per) in a forest which occasionally meet up for wooing and intermarrying between the bands.

Non-engineer doing research for a story... Recently, there has been discussion of colonizing Jupiter's large moons in the long term. One solution offered to the problem that the Jovian environment has lethal levels of radiation is to simply build colonies under the icy surfaces of these moons. This would also be done to provide access to the subsurface oceans of these moons. But this got me thinking about another potential problem...how stable is the ice? Especially if you are producing a town's worth of heat. Wouldn't you eventually cause so much melting that whatever foundation was holding your town in place would fall apart or collapse? Or have the ice shift in a way that would cause trillions of tons of it to squish your nice colony buildings? Or...are there ways (with current physics/no magic) to keep this from being a problem? Assuming you have the technological base to get people to the Jovian moons, would there be practical ways to brace/insulate/support the colony and/or divert heat away from the ice (radiator systems piping the heat to the surface, possibly capturing some of it for energy, etc.) so the colony would not constantly be at risk? I mean, eventually, they might have to replace some components, etc. but that's just normal wear-and-tear on any mechanical system. Sorry in advance if I am missing something obvious...as I said, I'm not an engineer, so I just don't know. Any thoughts on this? Thanks in advance.

It depends on development. One smart person with genetic knowledge and equipment would be enough. Theoretically, such a being would be able to artificially differentiate the offspring through genetic modification enough to avoid genetic diseases, or to make one-to-one clones without traditional sexual reproduction.. The creation of "Eve" from the body of "Adam" or vice versa is possible even with today's technology.

Non-scientist here doing some research for a story... I know that a species needs a certain minimum population to avoid dangerous inbreeding. I've heard different estimates, but the 500/5000 rule seems to be one experts consider reliable. Do all of these creatures have to be currently present? Could you, for example, have 50 individuals at any one time, but have 5,000 genetically diverse embryos in cold storage, and use artificial insemination to add new genetic material to the herd/pack/etc. every other generation or so? You would probably have to collect new embryos every once in a while, but it would take a while to cycle through your entire supply of embryos. Does this sound plausible? Or is there a better way to do this? Assume one reason for doing this is a lack of space--there is room for 50 of these animals (e.g., lions) but not 5,000 of them (i.e., a large rotating space habitat designed as a nature preserve). Any thoughts on this? Thanks in advance.

I was pointing out that Iceland already gets near 100% of their electricity from green sources and still has geothermal capacity to spare. Thus they may as well use that capacity to scrub the air. Then I noticed others said similar things and I didn't want to be redundant.

Right, so a collection of disparate observations, with no linking theme or thesis. That's rather what I thought. All very Sirius Cybernetics Corporation.
