Teempakguy:hehe....dats true, buh if we dont do that, we would be far behind time in the future..... check here for a little explanation |

RobinHez:chai, nah wah oh See as all of you just pretend say you no see the concept wey dey above. Dark matter is a theoretical concept needed to explain some discrepancies is astrophysics. It is therefore real. But, we do not know how it works. |
Re: The Sciences Discussion Thread. by RobinHez(m): 3:30pm On Jul 02, 2015 |
Teempakguy:lool....i already told u , u've watched too much sci-fi, dat thing is slated to be released in 2030......"when the technology needed is available"....wetin man talk put, when even the oyibo people sef never knw where to start... i keep hearing abt darkmatter, dunno what it is...thanks sha, will read more on it. |

RobinHez:dark matter is simply gravity from an invisible source. Imagine if the earth was invisible. Yet, it radiates gravity. |
Re: The Sciences Discussion Thread. by johnydon22(m): 4:38pm On Jul 02, 2015 |
Teempakguy:Basically speaking, darks matters are just energy forms that are not luminous. . . extremely opaque and emits no form of photons |

Slimzjoe:the guy won make us scientists over-night , like say na we invent ebola |
Re: The Sciences Discussion Thread. by XploraBen(m): 7:37pm On Jul 02, 2015 |
Teempakguy:I'm just blown away As in the time is approaching when all of the technology invented/used in Sci-Fi movies will actually be brought to use in real life. Technological advancement is taking a giant leap everyday in developed countries.Fro electric cars,to cars that run on gas,to wearable technologies,to robots...the list is interminable.Hope this could happen to Africa. |
Re: The Sciences Discussion Thread. by Slimzjoe(m): 9:11pm On Jul 02, 2015 |
RobinHez: No be small But atleast E dey Inspire me to Read more |
Re: The Sciences Discussion Thread. by RobinHez(m): 9:22pm On Jul 02, 2015 |
Slimzjoe:true. the guy is good, i also like dat johny guy only dat he doesnt believe in a God |
Re: The Sciences Discussion Thread. by Nobody: 9:27pm On Jul 02, 2015 |
XploraBen:LOL, Africa is alwasys there to buy from advanced countries. We really should start intensive research and development. |
Re: The Sciences Discussion Thread. by Nobody: 9:29pm On Jul 02, 2015 |
johnydon22:they only interact with gravitons. |
Re: The Sciences Discussion Thread. by Slimzjoe(m): 9:29pm On Jul 02, 2015 |
RobinHez: Science has a Way of Creating Doubts in our Mind.... Buh Anyone who doesn't Believe In something Is Confused |
Re: The Sciences Discussion Thread. by RobinHez(m): 9:42pm On Jul 02, 2015 |
Slimzjoe:lool |
Re: The Sciences Discussion Thread. by johnydon22(m): 9:50pm On Jul 02, 2015 |
RobinHez:lol |
Re: The Sciences Discussion Thread. by johnydon22(m): 9:53pm On Jul 02, 2015 |
Slimzjoe:Lmao the bolded needs clarification because "something" means "anything"...so in this regard it may mean believing anything at all i can come up with or assume up. . .so clarify what you mean by not believing in "something"? |
Re: The Sciences Discussion Thread. by RobinHez(m): 10:23pm On Jul 02, 2015 |
johnydon22:buh, is it not better to live ur life like there is a God and die then discover He doesnt exist, than living ur life in denial of Him, only to be reawakened to full acknowledgment of His existence? #just saying 2 Likes 1 Share |
Re: The Sciences Discussion Thread. by Slimzjoe(m): 10:24pm On Jul 02, 2015 |
johnydon22: The "Something" in this Context is the Same Thing as "Anything" Sen¤r |
Re: The Sciences Discussion Thread. by johnydon22(m): 10:44pm On Jul 02, 2015 |
Slimzjoe:Ok then bro. . i believe in love, i believe in babies, i believe in mum and dad, i believe in my girlfriend and i believe in you |
Re: The Sciences Discussion Thread. by johnydon22(m): 10:47pm On Jul 02, 2015 |
RobinHez:Basically means you believe the existence of a god out of fear of what he might do to you if actually he exists. . . its looks more like you believe out of fear and in a bid to secure your own and not because you actually know one exists. . . assuming there indeed is a god, do you think you can deceive him?....lol...bro lets leave the godly talk for the religion section, lets talk science 3 Likes 2 Shares |
Re: The Sciences Discussion Thread. by Slimzjoe(m): 10:49pm On Jul 02, 2015 |
johnydon22: Hahaa....Okay then |
Re: The Sciences Discussion Thread. by RobinHez(m): 11:00pm On Jul 02, 2015 |
johnydon22:wise decision man... but i dont believe outta fear, but out of the knowledge that i didnt come to be out of my own will...there must be an higher power directing the affairs of men |
Re: The Sciences Discussion Thread. by johnydon22(m): 11:06pm On Jul 02, 2015 |
RobinHez:They must, lol. . . basically shows you just think or imagine there is. . By subjecting reality to what you feel should be, you have limited yourself to what might be. anyway abeg i don't discuss religious inclined topics in the science section.... will be postulating my own hypothesis on the workings and plausible methods the hovering car teempakguy brought could be achieved |
Re: The Sciences Discussion Thread. by RobinHez(m): 11:33pm On Jul 02, 2015 |
johnydon22:ok boss....hope we meet some other place |
Re: The Sciences Discussion Thread. by Nobody: 1:06am On Jul 03, 2015 |
Hi there! Slimzjoe and Robinhez . . . I dey see you oh South African songs are cool. You should listen to it sometimes. Now, let me put forward an hypothesis concerning the hovcar above. Using electro-hydrodynamics, the car is being raised a few centimetres aboive ground by ejecting a charged stream of air. You can think of it as a repulsor technology. A formula I found on wikipedia is given by F = Id/k Where I is current, d is the distance between electrodes and k is a constant. Called the ion mobility coefficient of air, (Nominal value 2·10−4 m2 V−1 s−1) This indicates that at a high enough current, one can generate enough force to lift a car like that up. However, this also presents a power problem. Another idea makes use of magnetism. However, the roads will have to be made of metal. Also, there is also the problem of how to obtain superconductivity at high temperatures. Which brings us to rocket science. Actually, I think rocket science is the best candidate here. Thrusters located under the car provide lift. Whether to use jets here or rockets is the problem. I would go with jets though. gathering air from the sides of the vehicle, it is mixed with prestored and ignited. This causes an explosion which is then directed to thrusters under the car. Giving it thrust. Hydrogen can be easily acquired by stretches of solar panels that retrieve hydrogen from acidified water. Probably by commercial companies. At this point I drop the pen. Johnydon22 can continue from here. |

Teempakguy:now having hundreds of these things in the air....dont u see what it could cause; health wise? fumes from cars are deadly enough not to talk of this... |
Re: The Sciences Discussion Thread. by johnydon22(m): 10:19am On Jul 03, 2015 |
Teempakguy:Electro-hydrodynamics may achieve a lifting capability for the car but then again the amount of power needed for the energy needed to thrust the car upwards will be herculean. . . Working against a force of 10m/s we must provide at least a counter force of 11m/s then considering the weight. This option is totally unstable and power consuming not to talk of the inability for it to achieve levitation when the car is at rest (engine off) just like our model shows. It may be possible but yet still herculean and not to mention unstable and overly expensive. . . wouldn't bank on this option [b]I agree with this being the best candidate here seeing that the vehicle will require a relatively small amount of jet power to achieve flight. . But then just like robinHez said it would pose a threat of carbon(iv)(ii) oxide emissions which is bad enough with the number of cars we have now. I recommend electro-magnetic repulsion. .4 different magnetic fields of two distinct charges are placed side by side powered by a high voltage battery to create a high magnetic repulsive flux, the 4magnetic fields pulling on each other achieving levitation. . . again this falls on the backbone of how to achieve the large amount of power needed. And i think hybrid aircraft technology can be used too to achieve this. { A hybrid airship is an aircraft that combines characteristics of lighter- than-air (LTA), airship technology with heavier-than-air (HTA) technology, either fixed-wing or rotary-wing . A rotastat is a rotorcraft/ airship hybrid typically intended for heavy lift applications, while a dynastat is a dynamic lift airship typically intended for long-range cruising. No production designs have been built, but several manned and unmanned prototypes have flown. The term "hybrid airship" has also been used to describe an airship combining elements of different types of airships.} https://en.m.wikipedia.org/wiki/Hybrid_airship [/b] |

RobinHez: Dude, chill. Igniting hydrogen doesn't produce pollution. It instead produces steam. We are more likely to suffer from super-humidity than greenhouse gas pollution. |
Re: The Sciences Discussion Thread. by RobinHez(m): 10:56am On Jul 03, 2015 |
Teempakguy:still harmful |
Re: The Sciences Discussion Thread. by johnydon22(m): 11:01am On Jul 03, 2015 |
RobinHez:steam ain't harmful its not carbon(ii)oxide |
