    Only time I use candles is when there is a black out lmao.Its all intuitive in physics till its not.I used to think like most people in pushes and pulls but now I imagine energy planes.Try it instead of forces when doing questions, stuff makes sense.

    Hey Bro, Gravity is a natural phenomenon which happens and exists in nature. It started with people(Isaac Newton) theorizing about what causes objects to fall down when dropped, or what holds the planets in their elliptical orbits. Then Einstein introduced new insights briefly mentioned by CangeeroBear as gravity arising from the warping of space and time. They had to use a total eclipse event to prove that Einstein theory which stated light bends around heavy objects in space.

    Gravity is a phenomenon well understood only within the last 300 years through calculations. When Astronauts last landed on the moon, they tested the theory of gravity also by dropping a feather and something else heavier to demonstrate that absent of air friction(atmosphere), objects fall at the same speed unlike on earth where things fall at a different speed due their mass and friction. Since they knew that on earth, and theoretically two things should fall at the same speed no matter their mass, the moon landing offered a chance to prove that theory. Remember the moon has no atmosphere and gravity is way less than Earth's(again, that force that draws two bodies closer to each other which we term Gravity).

    The way I look at it, it is one of those things nature offered as a fact and humans have to accept it as it is. This is why I like Physics better than any other branch of science. It is more realistic and tangible. Things are really weird and can not be explained sometimes, but they are there and can be observed. Another good example of this weird phenomenon is how an atom/photon can be in two places at the same time. A single atom can be in two places at the same time but stops doing that when observed/measured as if the atom knew people were watching it. Weird right? Two guys Won the Nobel Prize for proving this fact in quantum Mechanics.

    I wrote in a hurry. I am at work. You take faith in the findings and accept it looking at the evidence(calculations and the fact that objects are subject to the force of Gravity everywhere). It becomes easy that way I think. Then learn how people derived the calculations.

    You got the joke bro.

    I also like to mention Weydamal, he is well read. Osman writes good also and is full of Energy. Good guys on the forum and useful for my geeky side.


    Not to forget TomBoy Nalle(a joke sis), whose passion for science is obvious.

    Out of the blue, I have a work date with a guy who will show me the process of melting Gold crucibles in a machine we use for research.

    If you folks are interested in some practical applications of science, I can share a little bit of what happens at work that is science related.

    One of the downsides to studying subjects of science in schools is the fact that many won't see the subjects applied in the real world and they lose interest.

    I am lucky in the sense that I am exposed to projects that are scientific and people share information if I ask what they are doing at work. Some can't indulge in what they do for patent related prohibitions and represent private companies using our institution for research, but others from academia are more open about their projects with us since we help them with their projects.

    Some of the stuff might be relevant to this thread. I am not sure. Because of my work, I was forced to study some chemistry, some physics, electronics, and technology in the nano scale..

    Take Care Guys For Now.

    @BestCaseScenario I just noticed something funny, I saw a moth flying in the air, if it wasn't for the light outside and it was pitch dark, I wouldn't of seen it, felt it, smelt it, etc. So what could be lurking around space in that deep blackness, just cause we can't feel it, touch it, smell it, hear it, doesn't automatically mean something isn't there. How do we get around this problem?

    The old age question of if we couldn't sense it does that means it doesn't exist.Imagine a world where you suffer from that disease, now if we could transmit information into your head you would still , if intelligent enough, deduce the moths existence.Senses are not needed, afterall we cant sense electricity or dark energy yet its still there.

    How do you reach a conclusion it is there without sensing it or at the very least having evidence left behind something was there like a feather left behind indicates a bird was there even though I don't see the bird with own two eyes?

    So what sort of evidence do you safely assume a moth was flying around in the darkness of your room with the lights off without it touching you, without u seeing it, no hearing, no smelling and it left behind no tangible evidence say for example a shit in your room or a thread of it's body?

    Dark matter and Dark energy are interesting as it would be similar to that moth that flew by me in the darkness and if it wasn't for the light, I wouldn't of seen it, heard it, felt it, smelled it, nor was there any evidence left behind for me to assess as it just went past me at a quick speed!!!

    If I was an atheist, I would say that moth never existed just cause there is no way I can prove it but does that mean it doesn't exist? Imagine how many things are lurking in the darkness and if you don't have the tool of lights, dna collection, sensory, audio tools, etc most people would say it doesn't exist but no that doesn't mean it doesn't exist, it just means you lack the available tools to detect it lol.

    Moth Exists, and because it exists it causes fluctuations in the universe.It works on electricity and hence affects the electro magnetic field around it.It is being affected by gravity and hence moves the earth towards it ,albeit extremely small,.It also changes the air around it and hence if u were to get an extremely fine piece of paper it would change with reference to the moth. Finally its using chemical energy and thus in a system the entropy changes , this can measured.All these measurements are possible with equipment , you body measures this through senses however we can measure these phenomena through other means.

    The point is, if these tools didn't exist and atheist would have to conclude anything we can't see, hear, feel, touch, or test with tools doesn't exist and that's simply not the case. What if the tools you have don't pick up things that are outside of your measurement tools? does it mean automatically that things don't start to exist just cause you cant test it or don't have the means to test it?

    We have this flawed understanding of things and we link it to our abilities, there are things that could be outside of our ability, it's so dangerous to limit everything you know just to human intelligence, it really is.

    I am impressed. Reality is, we don't know much of anything despite the appearance of knowledge and with the advanced scientific discoveries. Humans tend to exaggerate their abilities as you put it well bro. People had no clue about Atom and what it looks like hundred years ago. In fact, the man who first proposed things are made of tiny indivisible balls called Atom was ridiculed so bad by his peers he took his life by hanging. His name is Ludwig Boltzmann. Years later after his death, Einstein proved his theory by observing Brownian motion. History of science is amazing saxib and exposes the ignorance of people who claim God does not exist.

    That is why I dismiss all of them as ignorant people. They insult the human intelligence with their claims.

    Here is a brief video talking about Brownian Motion and How Einstein used it to prove Atoms are real even if you can't see them. Before his mathematical suggestion and argument, no one took the theory seriously and nothing useful was known About Atoms. Talk about Crazy. This was 1905. Amazing progress had been made in a century after this argument. This was the birth of Quantum Mechanics although it was not known as such initially. From here, in few years, classical physics head-butted quantum mechanics and Einstein himself was uneasy about the direction of physics lol. It was around the time he made the comment "God doesn't play Dice".

    This is an age old question. Does phenomena exist if one cannot see it, smell it, feel it, touch it, measure it etc. Materialist science would obviously claim that something doesn't exist if it cannot be measured, either by the senses or instruments. But this is a challengable concept, and one of the weaknesses of the scientific method, for the simple reasons that senses are limited and measuring equipments are not perfect or are still being perfected because technology is always evolving. To illustrate, before the advent of the microscope, we could not perceive or understand the presence and role of microbes, dna etc. The world of the small was invisible to us. So if you lived during this time, if a time traveller came to you and talked of an invisible bacteria called mycobacterium tuberculosis as the cause of TB, you would think him mad. Without the telescope, the night sky was full of lamps, shining from a distance.

    Improved technology has opened up the world of the small and the world of the large. If we assume that technology will always become better, it stands to reason that in the future , we will discover things that seem mysterious to us now, things that we confine to the philosophical, the spiritual and the the metaphysical.

    In other words , in explaining, describing and observing phenomena, we are bound both by the prejudices of our time and the technological advances or limitations available to us.

    Every minute we live, every discovery we make, should awaken us to the wonder and mystery of the cosmos.

    This is why I always quote the wise words of Hamlet:

    There are more things in heaven and earth, Horatio than are dreamt of in your philosophy.

    I would encourage you to take this line of applied science. While pure, abstract science is fascinating and rewarding on its own, and has often led to practical applications, I find that as a human being with limited time on this earth, a more practical approach to science has the potential to help others in society.
    For example, have you heard of the Groasis Waterbox designed by the Dutchman Peter Hoff? It's a low tech invention that captures dew or condensation in the air and releases it to a growing plant. It is being used to grow trees in the driest areas of the world. Condensation is simple , well understood concept, and a container to channel the water available in the air to a plant is the simplest thing to construct. You don't need to buy a fancy Waterbox, you can construct one if you understand the concepts of condensation and capillary action.
    Yet the impact is great in terms of tree planting in arid areas. Ninety percent of the trees grown using this method survive the harsh arid climates. Imagine what this could do for Somalia.

    This is the kind of science that I'm talking about, simple, effective up with huge impact.

    There is hope for semi desert countries like Somalia with the technology you describe. And I haven't heard of this particular technology. Seems interesting.

    I have a degree in applied science btw. It is a combination of many fields and was designed to help engineering disciplines in development/research/manufacturing settings . It was accidental for me to study for this degree and work related after I started at a low level in a technology company. To get promoted, they told me to get a college degree or start college and take applied science degree. They paid for it so I thought why the heck not.

    Although I am not an engineer, I do know more than engineering graduates and Phd candidates in some of their respective fields because I had been on the ground working hands on technically in the field. A working knowledge of chemistry, physics, and electronics was the requirement and that is what I did study in college for the degree.


    Saxib, you are educated. I like how you guys handle the English(better than me). You guys make me proud, all of you in this thread. Keep up the good work. My plan is to go back to Somalia inshallah in my later years and donate my time to young kids. Life is short and it is better to leave something useful behind. I am working on another degree slowly, which will take years to get due to my full time work schedule and other priorities.
