speaking of consciousness, pretty sure the robot wrote this.

It's one of the biggest mysteries of existence.

Some theories include:

It is a fundamental part of the brain and is a natural process within the brain.

Another theory is it originates outside the brain, outside of the physical world. Our brain taps into it like a radio taps into radiowaves.

Another theory is everything is consciousness and we are all existing within consciousness.

To this day we have no scientific evidence for how consciousness arises.

It is not changed, we preceive it as changed.

Photon thropugh water or glass is moving with the same speed as in the vacuum.

But that photon is striking into every molecule/electron it finds on its way. So we preceive speed of ray of light as 2/3 c for example.

​

Just like photon emitted in nuclear fussion in a core of a Sun - it needs about 100 000 years to be emitted to the Solar System, because there are so many molecules that its bumping into on its way.

That sounds like an issue that they should probably get working on then. If govs spent money in a way better suited to helping the people, and with a more logical tax structure, they absolutely could do it. I'm not saying canada's Healthcare system is some perfect model right now, it absolutely isn't, with many a flaw, But I'd still take it over the system here, where every life choice I ever make is built around minimizing the number of doses I'm likely to miss anyway. And I fully believe, with all my heart, that it is easier to fix a system that, at least in theory, exists to provide healthcare to all, than it is to fix one that is supposed to be profitable. I view profiting off healthcare as a moral failure.

Illegal isn’t the same as immoral. No legal code is perfect, depending on what you did you may well be a bad person whether or not there are legal implications to your actions

Is there a specific country you are talking about? It's so weird when speaking if Africa as one giant collective.

It's because the foreign aid is actually very little money. The famine issue can only be addressed by the government. Let's say you are sleeping hungry every night. A stranger gives you 100 USD. That's guaranteed to solve your hunger issues for a week or two. However, it cannot solve your problem permanently. You will steel need another 100 USD in a week or so.

If you got a job then you wouldn't need the 100 USD every two weeks.

The famine issue then, can only be solved by the government of that nation. There's no amount of foreign aid can solve it.

The foreign aid helps because we have some stupid governments in Africa. We have very corrupt leaders who use

I'm Kenyan.

The speed of light through any one medium (air, glass, a vacuum) is constant, so that is what is meant even we say "the speed of light is constant".

There is a limit to how fast something can go. c is the universal speed limit. Photons and other massless particles travel at that speed.

There is not a limit to how much gravity something can have. So, for black holes, they have so much gravity that their escape velocity is higher than c.

I'm not certain of this, but my understanding is that light in a vacuum is unhindered. When it's passing through a medium, it interacts with the medium and either doesn't travel straight, or is absorbed and emitted. Someone correct me if this is wrong.

First point is corruption, but we are not talking about the small scale everywhere corruption, but the large scale corruption of foreign aid. US pays foreign (development) aid to build a hospital. Now, the US doesn't contract the builder, they contract a US company that takes half of the allocated money and contracts e.g. a south african company which takes half of the remaining half and contracts an ethiopian company, which now has 1/4 of what was initially allocated to build this hospital. Now they take their share, have to pay some brides to get building permits etc and finally, they hire a builder company in ethiopia which now has 1/20th of a share and not enough to build the hospital. Hospital isn't build, although there was more than enough money to begin with.

Second point is companies like Nestlé, which simply take all of the water, so not a lot of crops can grow and to grow anything you would additionally need pesticides and fertilicer which are not just expensive, but also destroy the soil unless they are used continuously. So you get not that much food.

Third point: Climate change is real and already happening, so what used to be fertile land is now a desert. So less soil to grow things on.

Fourth point: Foreign Aid as US and EU did it was not really aid but just setting up ressource excavation points. We all heard about the Cobalt mines in congo for electric motors for example. Well, why aren't factories right next to them? Because we enabled better ressource extraction, now take those resources but do not leave any knowledge. Another example is chocolate. Ghana is the second largest cocoa producer in the world, but its share of the 100bn chocolate industry is 2bn. As the second largest producer it is 2% of the total and you rarely see chocolate from Ghana in stores, because we take the resource and the manufacturing happens elsewhere. There is also a huge brain drain, so the smartest people are convinced to come to US, Canada China and Europe.

Fifth point: Global market and global market agreements. Ghana produces a lot of tomatoes but you cannot make a living as a tomato farmer in Ghana. You used to be able, but now your tomatoes are bought in bulk from western countries and the market in Ghana is provided with subsidiced tomate paste or puree from e.g. the EU. Because Farmers in europe wouldn't be able to compete with the prices from farmers in Ghana, when both produce is on the european market. So they get money, and so much money, that it is not worth it to sell their own tomatoes in europe, because you would need more quality checks and had waste if a customer had to look at it. Therefore you sell your subsidiced tomato to a tomato puree manufacturer who now has so many tomatoes and product that he sells his product not just in europe but ships it to the whole world ans also back to Ghana. For cooking and storing puree is the easier option, so people buy the puree. The tomato farmer in Ghana cannot sell their tomatoes in Ghana, because it is so much more expensive compared to the cheap puree. So they have to sell in bulk, which means lower prices per tomato. They can never compete with the subsidiced tomato puree, they do not see anything from the large margin of profit which leads to our prices in the stores and they therefore cannot build their own self sustaining economy.

So you have: less and less fertile land/soil to grow things on, less and less water because corporation like Nestlé (Quote of Peter Brabeck-Letmathe CEO of nestle 1997-2008: "[...] The one opinion, which I think is extreme, is represented by the NGOs, who bang on about declaring water a public right.That means that as a human being you should have a right to water. That's an extreme solution.") buy the rights to water and simply do not leave for the people. Inside this also falls stuff like Palmoil, where the trees suck up all the water around so you cannot grow anything there and often for years destroy the soil. Corruption Climate-change And not actual development or foreign aid but just colonialism with a new color

And the thing I haven't mentioned is wars, which also lead to famines.

Welfare makes people dependent and eliminates competition. The local farmers have no reason to grow food they can't sell for a reasonable price (livable wage) since they are competing with "free" food from the foreign aid. All sorts of industry and manufacturing is harmed as the foreign aid reduces local production of food and all the other local business that would support farming, tools, vehicles, etc. needed. Can'tcompete with "free".

Mass bend space time, thats how we get gravity. A black hole has so much mass that it completely warps space time to the point where outward is not an available direction anymore.

Sometimes people visualize gravity using a rubber sheet and various balls. In this analogy a black hole would be a ball so heavy that it tears a hole into the sheet and if another ball then would fall into that hole it is off the sheet and can't get back on it.

Gravity curves the spacetime around it. We have a hard time visualizing what that looks like in three dimensions, but you can think of a massive body as bending spacetime inward toward itself. Being so massive, black holes bend spacetime to extremes. The curvature is so great that, for an object within the event horizon, there is no trajectory in spacetime that will take you outside the black hole. Rather, spacetime is so curved that all trajectories into the future converge on the singularity at the heart of the black hole.

Ukraine produces a phenomenal amount of food that's sent to these countries. Considering what's going on there, they have their hands full and can't produce at their usual levels.

Edit: the world's largest grain exporter is attacking the world's 5th largest grain exporter. Russia is now experiencing embargoes, limiting their sale, while Ukraine is being assaulted by Russia, reducing their output. This is having an effect on supply and prices.

Adding explanation since someone was having trouble understanding the whole picture.

Unremittent aid kills the entrepreneurial engine by enabling big government and undercutting prices.

>With aid’s help, corruption fosters corruption, nations quickly descend into a vicious cycle of aid. Foreign aid props up corrupt governments – providing them with freely usable cash. These corrupt governments interfere with the rule of law, the establishment of transparent civil institutions and the protection of civil liberties, making both domestic and foreign investment in poor countries unattractive. Greater opacity and fewer investments reduce economic growth, which leads to fewer job opportunities and increasing poverty levels. In response to growing poverty, donors give more aid, which continues the downward spiral of poverty.
>
>This is the vicious cycle of aid. The cycle that chokes off desperately needed investment, instils a culture of dependency, and facilitates rampant and systematic corruption, all with deleterious consequences for growth. The cycle that, in fact, perpetuates underdevelopment, and guarantees economic failure in the poorest aid-dependent countries.

TLDR: Nobody really knows...

The speed of light does change depending on the medium it is passing through. For example, it is slower in water than through a vacuum and slower through glass than it is in water.

That, however, isn't relevant to the question being asked by OP.
