Technology / Re: Altering orbits using earth's magnetic field or generated fields from earth?

« on: 27/05/2020 22:35:24 »

I assume the energy you are hoping to create is due to your movement through the field ? This is a law of physics that escapes me at the minute but it had something to do with an airplane oving through the earths magnetic field and how much charge it would create its also constrained by energy conservation, basically you have to put energy in to the movement to get the electrical energy out.

Is it possible to use the earth's magnetic field to move around in space, or even take off from earth?

The earth’s magnetic field is very weak compared to the force required to move a spaceship. It can move a magnetised needle on a low friction support, but anything heavier like a bar magnet on a desk doesn’t move. Also even a weak bar magnet will easily overpower the earth’s field and influence a compass needle
As we get further from earth the earth’s magnetic field gets weaker, but a magnet will still be able to align along the field see

Notice how the magnet is stronger than the earth’s magnetic field.

How about the radiation fields ?

While they obssess over Christians, they pretend we are all perverts, evil, two-faced beasts. They know that millions, the vast majority of Christians are lovely, good, decent, honest people and the fact that they never mention that proves they must strain to argue their side.
Christ laid it all out on the pages of the N.T. Didn't pull punches. Didn't try to sweet talk HIS opponents. He told them what HE thought with candid authority. They murmured and plotted. They ganged up on HIM secretly using every devilish manipulation to have their will done. I wish I had been there. I would loved to have seen it unfold. Each part coming to pass in brief snippets of time, I'd be observing it all go down, just as we read in the N.T. The smell of the Passover meals cooking, the swirling aroma in the air, the sounds of children in the background, the enormous stones they carved to form the buildings, the clothing ancient women wore, their gnarled teeth, the swords the men carried. What is really weird is that it really did take place. It happened. Long, long time ago. Just as they said.

So

Hi Halc.  That explains that then!  It's a typical knee jerk reaction from a newbie like myself when he thinks, hey something DOES travel faster than light! I guess that if the article was aimed at a non scientist like myself then it would have said the neutrinos get to Earth earlier than the light 'because ...'.

You too can travel faster than the speed of light, quite easily actually.

A moon is only a moon if it is spherical i believe, if not it is just a satelite, of which jupiter has lots and lots. If a noon had a moon it would have to be very big, or considered a binary pair as what  constitutes a satelite is  orbiting an orbiter.

That CAN'T be true! / Re: Is the mystery killer of the Bermuda Triangle killer waves?

« on: 09/12/2019 06:19:22 »

The Bermuda Triangle does not appear to experience losses of ships and planes at a greater rate than other areas of the world based on percentage: https://www.independent.co.uk/news/science/bermuda-triangle-mystery-solved-latest-theories-dr-karl-kruszelnicki-debunked-unexplained-a7861731.html

If there was some kind of anomalous loss of vehicles, however, killer waves wouldn't explain the loss of aircraft.

I think that needs clarity, hurricaines, the gulf stream, reefs and rogue waves are all going to have an effect, especially on old wood galeons. Its not the only known trouble zone, anywhere with tropical currents and hurricaines is going to have a higher occourence of  rough conditions. The south seas are better known for freak waves as the uninterrupted curculation inflicted by pacific atlantic and indian incursions. I do concede that the bermuda triangle is a bit of a bottlekneck during empire times.

Physics, Astronomy & Cosmology / Re: What happens when both slits are observed by in the double slit experiment?

« on: 07/11/2019 03:09:55 »

The point of the double slit experiment is that one or two slits, the transmission medium behave the same.  Its the wave effect, if you put waves through two slits you get destructive and constructive interferance, leading to high and low points along a wave crest. Ie a wave crest now has peaks and troughs along it aswll as a trough between the following and preceeding waves. Lots like when 2 oceans meet. Point is that light is behaving with these wave characteristics.

Interesting point really, it may signify the big bang was not singular within itself,  that further tangent events appened after the big bang.

Of course variances can be generated by gravity ie bigger mass affecting smaller mass, but to have galaxys vectors significantly altered would take alot of mass.  Perhaps the blackhole and where it goes to is capable of pivoting galaxies ?

Technology / Re: Why are Some Fridges Hard To Open Again Once Just Closed?

« on: 05/03/2019 08:41:59 »

Im gonna go for condensation of water

Warm air condensate in the fridge creating a vacuum, drill a hole through the door.

 It  is more likely though it is on the on the seal and frame as it would probably take longer for air to fill the void. It could just be a slow release suction on the seal or it could be a bit of condensation too. Water condenses from warm air onto cold surface when the door is opened. Upon closing of the door the seal is formed. The water continues to condensate out around the seal creating a vacuum  until it works air around it to compensate.

I believe manufacturers already have thought of the condensing water air trick for the box, i think there is a pressure release tube, yours may be blocked .

General Science / Re: Our brains are anatomically the same, so why do our personalities differ?

« on: 06/02/2019 11:02:24 »

We do not differ very much at all, but this is not governed by brain similarities. If you think about pain laughter fear sex emotional hurt happiness they all rule us. We are very very similar. If you look microscopically for the differences you will find them, but that is because you are looking for them.Its wrong  to think that your brain makes your personality, if someone is born in a war zone they develop an outlook and a personality as such, conversely if they are born into the monied side of the world the personality is one that fits that. But on the grand scheme of things the human psyche is most very very similar and governed by biological alterations, such as testosterone in agression, men have more risk taking confrontational personalities that is wholly governed by a hormone !

Gravity
Pushes

Just like hydrology, if the masses are within the angular pressure radius drop distance they attract in a converging way, not necessarily to inpact. The angular radius of gravity is infinite, giving rise to the feeling that there are 2 types of gravity.

Technology / Could diesel be made clean?

« on: 10/01/2019 12:47:17 »

Not counting efficiency, could the diesil engine be made clean ? Deisel engines where initially used for there high torque output espexially at the low end of engine rpm compared to petrol engines, lorries buses tractors etc used them as they provide lots of slow constant power. It is only in recent years diesils heve become popular because the fuel takes less energy to create ie refine and is more efficient and given that turbo diesils have developed, they also now give higher acceleration, somewhere near that of petrol engines. We have all been told by different mechanisms to buy deisels and then not to, yet it doesnt seem that we will be getting rid of large diesil vehicles any time soon, as even though a bus could run off petrol, it is likely that the efficiency versus the present diesil engine would be far far below the efficiency of having a bus with a diesil engine and that means citys and motorway avenues full of dioxins from diesil.

Unfortunatley as anyone with a brian and a bit of experience could have told the governments of earth before they started pushing diesils,  what comes out of a diesil exaust is very very toxic. Is there any reasonable way to process the exaust gasses such as reburning the exaust ( efficiency not withstanding) whilst the vehicle remains largely as mobile and as maintainance free as prior to modification.

New Theories / Re: Does man's use of energy in the last 200 years mean global warming is man-made?

« on: 02/03/2018 03:05:19 »

OK, back onto the Tsar Bomb. Earth is already not a perfect sphere, the kinetic energy released by the disruption of the tectonic plates would not take the planet out of it's original?
 I mean the earth orbit the sun where it is because it's center, if you disrupt the outside layers and flow of magma, wouldn't the center be re-centered somewhere else for some time?

Not really alter the orbit because as one load of mass is forced one way an equal and opposit3 mappent the other way, but if you re arrange the mass you alter the gravitational centre. It will alter the length of the day though i think by countering the rotation of the earth some how

Yep but having to go into the different forums and out again gets a bit tiresome,

That's a nice suggestion about drop-downs, but quite a hefty job to implement; I might put that on my list for a longer-term project...

But, just to flag - and you may know this already - you can see what's new in several ways:

1) Click on "RECENT TOPICS" at the top - or https://www.thenakedscientists.com/forum/index.php?action=recenttopics

2) Use the "POSTS" dropdown option at the top and select either "Unread Replies" for an amalgamated list of all the new replies in threads in which you have participated (indicating which board), or "Unread Posts", which is a list of ALL the new posts made in any board, forum-wide, that you've not reviewed yet.

Hopefully that's helpful.

That is massivley helpfu, maybe im computer useless thats all.

Another suggestion, or hopeful ask maybe

If in a thread lots of people post arguments and quote each other repeatedly  a thread can get a bit diluted and cumbesome see this one i started

https://www.thenakedscientists.com/forum/index.php?topic=71332.100

The detonation of a Tsar Bomb at the Mariana's trench, at the bottom of the pacific ocean would surely move the planet out of its current position...

I'm guessing you watched that video from Ridddle too, huh? It's a load of bunk. Tsar Bomba could do nothing to significantly change Earth's orbit, regardless of how you partition the energy. Keep in mind that the asteroid that left the Chicxulub crater released about two million times more energy than Tsar Bomba yet even that didn't push Earth significantly.

Seems wierd that to me, perhaps a contender for dark 3nergy or dark matter.

Apparently the collision of the primeval earth at an angle with another planetoid did not alter its orbital plane either.

No
We are on a rock flying through space. We can only alter that path if we have something to push against and , since nothing arising from such a detonation would leave the earth, it can't push us.
That's pretty basic physics, formally referred to as the conservation of momentum.

We are not flying through space, there is no air, we do not have wings. The earth could be stationary, and as there is no up down left or right i cannot see how we have motion and cannot see any reason to necessitate flight,  or any means to instigate it, as we have nothing to push against.

"If by mans activity during the hours of daylight (point of the earth facing the sun) applies force to the surface of the earth, whilst by the hours of darkness he is static, would this activity have an effect (however small)  to permanently alter the distance of the earth from the sun"

No.
The laws of momentum conservation make this impossible.
Essentially, nothing on earth can change the earth's orbit, because it would have nothing to push against.

The detonation of a Tsar Bomb at the Mariana's trench, at the bottom of the pacific ocean would surely move the planet out of its current position...
Needless to say, gigantic tsunamis would kill most of humans on the process witch given the facts is not entirely a bad thing...

I would say yes and then it would return to normal, as everything settled back to its position.

If you roled earth up into a cone it would still orbit around the path it is now.

I believe the earthquakes shortened the length of days by a few fractions of q second, maybe a Tzar bomb would do that?

That is if none of the mass escaped into space
