    Black Hole Question

    i don't think it's nonsense thats why i post here, of course nature does not care what i think however thats just the problem, we as tiny spec humans on a tiny spec of dust does not know it all, anyway i will end this discussion here as i know it's starting to get a bit off topic according to...

    Black Hole Question

    Thanks for the replies, i feel that most of my questions have been explained above thanks, just the one about space time and what goes on in the blackhole where we cannot see anything. Here's how i see it, you cannot punch a hole through the invisible air we breath on earth, however beyond...

    Black Hole Question

    I am no cosmologist, just purely curious as to what the explanations and if there are explanations currently to some of my questions: If it was possible can one fly far enough around a blackhole in all 360 degree angles, i assume yes one could but what the question leads to is, does it have...

    Electric Fuel pump question

    Thanks so much Fleebell for that brilliant explanation, i have put the pump in a bucket with petrol and good news it's working :) I now am ruling out pump failure, and hopefully just an electronic problem like a relay in my car, or a blocked pipe, (hope the pump is still pumping sufficient...

    Electric Fuel pump question

    Attached below is 2 pictures, encircled in yellow is where iAttached below is 2 pictures, encircled in yellow is where i connected the 12 volts (i removed the wires first) then connected it to the wires of the motor. when i ran the motor and try to blow or suck, at the external pump outlet i...

    Electric Fuel pump question

    Thanks Travis, is it possible that it could have a solenoid actuated valve that only allows for flow when the pump is inside the petrol tank ? (coming to think of it, i get the feeling that is actually what you jusr said by referring to a "check" valve. Is it electrically activated/controlled...

    Electric Fuel pump question

    Good Morning Please can anyone help, i would like to know if an engineer can tell me how this fuel pump works, i'm trying to establish if it is faulty or not, my actual fuel pump is shown in the pictures below, when i try to suck on the outlet or blow into it, i cannot get air through it...

    Fabric of space ?

    Good questions, and i don't have the answer. A shadow is caused by something obstructing light, without light we have blackness, so i'm thinking if the sun creates light, what creates the blackness. What it is made of is a good question, perhaps we are limited by our very nature, ie...

    Fabric of space ?

    Now that is an interesting reply. And you have the definite proof that qualifies you in making this statement ? Please refrain from posting ridiculous replies if you have nothing to put on the table.

    Fabric of space ?

    I know currently there is no answer but please be open to theories or possibilities for this intrigues me endlessly: Everything is made up of something, so the fabric of space must also be made up of something. i'd like to know if it would be possible to "poke" a hole through the fabric of...

    Tunnel inspection tech ?

    This is purely for visual inspections. The tunnels will be drained during our testing, and we have geo-hydrologists that will measure the hydraulic conductivity with packer systems around the tunnels, this will show up any leakage in to the surrounding bedrock and earth. We do hydraulic...

    Tunnel inspection tech ?

    Thanks Rollenstein sounds interesting, however the vehicle won't be submersed the tunnel would not be completely dry. We are toying around a "leaky cable" system, that we will drive out with a tracked vehicle attached to a strong cable for retrieval. This way we can send radio signals along...

    Tunnel inspection tech ?

    Good afternoon I'm doing geological surveying, magnetronomy, Orthomosiac photography and visual inspection of structures, with our UAV's I am currently developing a radar/laser guided system for inspecting hydro-electric tunnels. I want to incorporate it with a 360deg photo of the tunnel...

    Expanding universe into what?

    So then is it like the universe is infinite and everything inside it, is just moving further apart from each other, that is, if the universe is really infinite.

    Medical Electric field effects in tne brain

    Maybe i heard my brain's electric field switch off and on for a split second? One night when i was sleeping and for the first time ever while in a deep sleep (only way i can describe it but like a Physorg article said , it's really interesting how deeply/closely the mind and body is...

    Turbine blades

    Why not instead of fuel driving the turbine for compression use an electric motor? With high efficiency brushless motors, could this not be possible? I suppose you'll tell me that the losses would be greater than the gains, but improvement, innovation is key, then let's improve upon the idea...

    Turbine blades

    I so want electric to take over the world, i mean it just has to, fuel for turbines as it is today will come to and end anyway. An electric turbine would be awesome! Do not give up on this!, the best attempt at an electirc turbine i've seen so far is the DSM 94 HST fan by scheubler for...
