This is the thing which are claimed by such politicians as Angela Merkel, Macron, and some British prime minister. Do you want me to find the links? Do you regard them far-right? And many others. Vladimir Putin. Trump is building the fence with Mexico for some reason. Could you name some well known entrepreneurs, scientists etc, who are immigrants (or their descendants) from agrarian/resource based countries? Well, there are few of them, but they already came to the West with huge money, rather than earned them from the scratch in the West.

I wonder whether modern industrialized nation are not going to do something to increase fertility rates of their native and most educated population and whether no one influential is even thinking in this direction. But it looks like some major social and economic changes will need to be implemented to correct the problem. Immigrants are coming from different countries. For example from coastal China, Korea or Eastern Europe. But now these countries started to experience demographic problems themselves and cannot be regarded as a bottomless supply of immigrants. But if we are talking about immigrants from predominantly agrarian or resource selling countries/territories, are you sure they (and their descendants) are more successful than native population in developed countries?! Where did you take these speculative statements from? Majority of politicians and researchers claim rater completely opposite things...

Population native to nearly all industrially developed nations is not self sustainable demographically. They could retain the same level of population (or small growth) only due to immigration from less developed nations. More and more of these immigrants come and will come from the countries which were not even fully industrialized. What do you think majority of modern industrialized countries will look like in 40-100 years? Do you think they will experience no sharp and long term crisis in this timeframe and no major revision of existing model will be needed? Do you think there will be at least the same pace of the scientific and technical development and economic/social output in 50-1000 years as now, if present demographic trends will continue? Ethnic German females produce less than 1 child on average, 1/3 of 35 years old Japanese are childless... Average fertility rates by country. Grey - less than 2, yellow - less than 3, orange - 3-4, red - more than four. The CIA world factbook is taken as the source. I suspect that data for Saudi Arabia and Turkey could be incorrect.

I thought photons have no mass only in the state of rest, hypothetically. But could they practically exist in the state of rest? Probably not. If they are neither matter or pure energy then what are they? It is not known exactly whether neutrino does have any mass. If not, does it mean neutrino is not a matter? Why matter suppose to have mass? I though that according to widespread philosophical definition matter is at least: "everything that exist independently of our perception/imagination and that could be perceived by any means of our perception". Though some kinds of matter, possibly, will never be detected or perceived by humans. As you see there is nothing about the mass in the state of rest. Photons cannot leave black holes and attracted by stars. Therefore they suppose to have mass in the practical sense.

This is really strange. In some countries any kind of physical fields (such as EM, gravitational) and bosons are regarded as a kinds of matter. I see no reasons to think of photons as not kind of a matter. If not, than what is it? There exist matter conservation law. If annihilaiting matter converts to photons, then it means matter disappeared and matter conservation law was violated?

To my knowledge energy was never isolated in a pure form by any scientists. According to modern generally accepted views energy is just a varieties of a matter movement forms and as such it cannot exist in a completely isolated form. Also there is a potential energy as well, it cannot exist separately from the matter. When matter and antimatter annihilate - they create gamma photons which are just another kind of matter.

It is claimed that electrons in graphene are effectively massless at certain points and tunnel "through barriers of any height and width". If they are "massless", what is their De Broglie wavelength equal to? If it is equal to infinity, does it mean they exist "anywhere in the Universe"? https://phys.org/news/2011-11-secrets-tunneling-energy-barriers.html What is the "barrier width" and its difference from the "barrier height"? If electrons in graphene can tunnel through the barriers of any width, does it mean they can completely negate any distances?

What is practically known about radio soliton communications? For example, how much would it allow to increase band width and reduce interference? https://www.nist.gov/news-events/news/2010/09/new-wave-spin-soliton-could-be-hit-cell-phone-communication https://dspace.mit.edu/bitstream/handle/1721.1/4154/rle-tr-599-35197933.pdf?sequence=1

Here is something about distance independent quantum related energy transfer: https://onlinelibrary.wiley.com/doi/full/10.1002/anie.201703539

It seems now more details are reviled on how Lithium may switch between different Fermi levels. The whole thing looks to work like an EDSL supercapacitor and exploits some quantum effects: https://link.springer.com/article/10.1186/s41313-018-0014-8 Could someone make comments about this tunneling? Not clearly understood how Lithium can equalize its electrochemical potential with either Carbon or Sulfur without making any chemical bonds with them. Is it possible?

Could there be a way to transfer energy for a long distance (miles to hundreds of miles) by using some slight variety of the "quantum entanglement"? Probably it needs to differ from the classical one when coherence is destroyed. Of course the speed of transfer supposes not to exceed the speed of light.

Could you advise some of the best crowdfunding sites which aren't scummers and don't collect mandatory all the personal and banking info? Thank you

From reading the original article I posted in the beginning I got impression they are talking about some kind of a "quantum entanglement" and no classical magnetic field is used between the sender and the receiver. If I'm wrong could you explain what is that?

So, how exactly quantum mechanics is involved here? https://ieeexplore.ieee.org/document/8639115

Could you comment this one article? There seem to be very few info on this technology. How exactly does it work? Could it really work at any distance? At what efficiency? https://arstechnica.com/science/2017/06/quantum-principle-harnessed-to-create-easier-wireless-charging/?comments=1&post=33496691 https://www.researchgate.net/publication/318092214_Robust_wireless_power_transfer_using_a_nonlinear_parity-time-symmetric_circuit

Transient non-integrative expression of nuclear reprogramming factors promotes multifaceted amelioration of aging in human cells https://www.nature.com/articles/s41467-020-15174-3

Why do you think if it would be possible to stop aging in all the cells in general, neurons are going to be the exception?

So what is the problem if we would be able to stop neuronal aging at the cellular level? Even if it would be possible, it is very dangerous because if human personality could be digitalized and stored "at the server" it means it could be easily enslaved. But for now I don't see how it could be done with any technology I can imagine because brain functions are closely connected to a physical and chemical properties of the brain matter.

In this case it is more important how neurons are connected to each other than the cells themselves. There seem exists copying mechanism in the brain which transfers the old connections to a new regions of a brain. Certain "brain plasticity". For example there are many cases when after destruction of some narrow brain region other regions took the functions of the destructed region and person almost completely recovered. I think there are not too many cases when after a stroke all the memories and personality would gone forever and completely.

Are there any scientific experiments which prove it? For now I don't know proves memory and personality are stored at the cellular level. According to some studies new brain cells are created until death. Also it may not be necessary to replace cells but just stop aging at the cellular level.

Don't you think that insufficient funds are allocated to combat aging and this technology is coming late for a common public? This is a problem which affects everyone. What funds could be allocated if every person in relatively developed countries would give $1000 USD to combat aging and how soon some sound results will appear?

If it is assumed that men-made gases cause greenhouse effect and this is really terrible, then why humanity cannot create some potent gases to counterattack the problem? For example some potent agents which reflect well only UV rays and harmless to any leaving beings? Would not it help to cool Earth down and protect leaving beings from UV rays?

Can someone explain how MHD can work on electrolyte solutions similar to a salt water? If there is no free electrons but only positive and negative ions than what runs through the external circuit to generate power?

Changes in electric polarization could be achieved with help of electromagnetic induction and magnetic fields it seems, we don't necessarily need a plates or free charge accumulation. Magnetic fields are formed around wires when current passes through. Possibly it may resemble magnetic polarization of a permanent magnet when current passes through. I guess we may store energy in a permanent magnet as well by polarizing it first and then retrieving energy back in form of electric current when magnet looses its magnetic polarization for some reason. For example demagnetizes spontaneously. But permanent magnets are not capable to store a lot of energy. https://www.sciencedirect.com/science/article/abs/pii/S030488530500939X There is also such effect as dielectric adsorption in a dielectric capacitor. https://en.wikipedia.org/wiki/Dielectric_absorption

Why is it important?
