Indian Military Incompetence


IAF claim of hitting F-16 by their Mig 21 before having been shot down by PAF gets exposed. All 4 missile seeker heads recovered intact from the wreckage & held. Pakistan and its professional Armed Forces staying humble

Even our sun bends light close to it , light being pulled in by black hole is not that interesting considering scale of density of mass.

It should interest u to know that some stars collapse on themselves and produce high pressure enough to convert their mass into a single crystalline solid diamond , so basically we have millions of stars which r planets of a single diamond shocked

If u manage to bring a small piece of the diamond and weigh it on a weight scale with earth on one of the scales , the small piece of diamond will have enough mass ie weight to outweigh our entire earth shocked

Anyways what is interesting is what happens on the point of singularity / on the other side of the point .

Point of singularity is the black hole where the event horizon breaks or simply stated everything being pulled in ends up there and nobody knows what happens after that.

Energy is constant , one cannot make or destroy it , so the energies at the point of singularity and importantly beyond it must manifest into something.

Then there is the mystery of dark matter , possibly it could be related to the black hole.

And also it's effect on time , black hole will dilate time on our side of the singularity , so a person orbiting a black hole will spend 1 hour which will be equal to 1 year or more for a person on earth ( time scale is not correct just to give u a idea of difference )

Also time on the other side of singularity will be a mystery , will it exist , nobody knows.

Let me ask u all a interesting question which nobody seems to ask

What is time ? Why does it exist ? How does it exist ? grin
Time is the fourth dimension of any body that is used to measure events. The other three dimensions are length, breath and thickness.

Time exists to bring orderliness in an otherwise chaotic world. It helps us make sense of the other three dimensions.

Perhaps time existed before anything at all, even before Big Bang and the current expansion of the universe.

Without time can anything exist at all?

Multi-Mode Hand Grenade - Shivalik developed by DRDO

Modular in design: Two modules, i.e, fuze and main body, light in weight: Gross weight is 490 g in defensive mode and 260 g in offensive mode.
serves as both Offensive and defensive grenade i.e Lethal radius of 3 to 5 m from point of burst in offensive mode. In defensive mode, it incapacitates human being with in the radius of 8-10 m from the point of burst Uniform fragmentation pattern. More number of fragments (>4000) embedded in plastic matrix to provide higher splinter density of fragments. Time delay 3 sec and arming delay of 0.5 sec provides additional safety to the thrower. Maintenance free and highly reliable. Operational temperature range of -20 ºC to 55 ºC and storage temperature range of -50 C to 75 C .

Mechatronic fuze for multi-mode hand grenade operates in three modes, viz., time delay, impact, and dual. Pre-launch safeties have been provided through mechanical components whereas post launch safeties and intelligence have been incorporated using embedded system based electronic hardware and software. The detonator is misaligned with the rest of the explosive train during storage and transportation. The fuze is powered by primary lithium battery. The fuze has been designed to withstand accidental drop for thrower’s safety. The time delay for arming and initiation of detonator is factory settable with a high precision. The fuze has a provision of self-discharge system to avoid delayed initiation after a preset delay.

note:to change from defensive mode to offensive move u just have to unscrew (remove) the outer fragmentation sleeve and vice versa

Still does not answer the following questions

What is time ? Why does it exist ? How does it exist ? grin

So u have height , width , length which u can measure , the measurements will hold true anywhere in universe , but will time measurements hold true everywhere ? Answer is no grin

99.99 of visible universe is chaotic so.........
Time is relativistic which means it depends on the observer so on the contrary it adds to chaos rather than stability.

Rate of time varies widely in different planets , stars , galaxies etc across the universe so.......

Time cannot exist before big bang because nothing existed then , without light ( space ) time cannot exist and without observer time cannot exist since time is not a concrete universal parameter which exhibits same values across the universe .

Time is a abstract construct based on interaction of movement in space so time is not a defining parameter light is , it creates the space where the observer relativistically measures time from his point of reference.
Re: Technical Discussions On International Military Equipments Doctrines Tactics Etc by Nobody:
AFAIK
1.
TIME came into existence the moment LIGHT came into existence

TIME and LIGHT are synonymous if one can grasp the fundamentals.

So TIME exists because LIGHT exists , however time values is relativistic but light value is constant

2.
LIGHT ( which is basically energy manifestation ) propagated from the first source ( big bang ) ever expanding and without any limitations whatsoever.

TIME propagated ( came into existence ) from the big bang ever expanding and without any limitations whatsoever.

So as LIGHT exists basically due to the time travelled by the light.

Eg events that happened in a star millions of years ago we can still see them , because the light rays from the events of that star is yet to reach us since light takes time to travel which is calculated in light years in astronomy. Basically we can then see millions of years back in time.

Eg if we travel faster than light ( which is impossible ) we can jump time ie move into future. However due to conservation of space time continuum , we will end up in a parallel world ( space time continuum ).

Existence of Tachyons which are faster than light lends impetus to jump time though in another event space , not in our event space.

Another example if we travel close to speed to light which is possible , then we can stop time to certain degree ( dilution of time ) . Time is RELATIVISTIC meaning it depends on the observer / events associated with the observer . So a observer travelling at speeds close to speed of time will age slowly than another observer on earth.

3. What is time

TIME is a abstract construct which is a result of relativistic interaction of LIGHT ( movement in space ) and a observer.

Note : Movement in space is dependent on light because creation of space is a result of distance traveled by light.

*I can recall we've had a discussion on relativity of time, so I will skip that.

Time is what the clock says. grin

Time exists because we're moving slow enough. If human can create a machine that can travel (perhaps faster than the speed of light) time would freeze and become irrelevant.

How does it existhuh
Because the earth is spinning on its axis. undecided

Best answer grin

Traveling equal to speed of light will freeze time for the people inside the machine only.

Actually time will not freeze , what will freeze is the machines ( and the people inside it ) speed with respect to the rest of the universe (expansion at speed of light ) . That is relative speed will drop to zero wrt speed of light , which will make the observers feel rest of universe is at standstill however contrary to their observations , events in the universe will move along as usual. grin

So effect of time stop is localised to the observer in the machine moving at speed of light only .


Spin determines the time period of the planet rotation / revolution in concern , not related to time.

Different planets stars galaxies have different time periods these r localised effects based on gravity and space interactions. Not related.

Re: Technical Discussions On International Military Equipments Doctrines Tactics Etc by Nobody: 10:42pm On Apr 12, 2019
klhazhik:

What is (a) Black Holehuh
Simple explanation a star hundred or thousand times bigger than our sun in its dying years collapsed on itself ie the entire mass of the star started compressing onto its centre untill all the stars mass ended up compressed into a point ( imagine the tip of a needle holding all the mass of star ) in space .

This results in infinite density in a point in space which inturn results in infinity gravity in and around that point in space , as a result nothing can escape the pull of the infinite gravity in and around that point , including light.

Since everything in the vicinity of the point of infinite mass is sucked in including light , that point in space is called a Back hole .

A black hole is not visible directly , it can be detected indirectly only via the unusual behaviour of orbit of neighbouring stars or planets etc due to the strong gravitational pull of a black hole but at a safe enough distance not to get pulled in.

The point of infinite density is also known as the point of singularity , it is a dimension less point with infinite gravity and density.

Our big bang is also hypothesized to have been a singularity when it started.

Also surrounding the singularity is the event horizon which is a hypothetical region of no return. We will never know what is beyond the event horizon since nothing can escape from it .

Now important thing to realise all these are postulates and theories which gives the best possible explanation of the phenomenon of black holes till date.

It will take many more Einstein's etc before we can come up with a solution which gives all answers which can be verified 100%

On the hindsight we believe in God without even one shred of evidence grin

I hold the opinion that the birth of the universe came into existence with the formation of matter (mass irrespective of its magnitude) at the point of the big bang and that time is what intelligent beings use to measure and grasp the dynamic changes matter undergoes in its interaction with forces like gravity, energy etc.

Nemesis8u does this opinion hold water?

Seened:

Well regarding Ur believe that light has mass.

In classical physics mass of an object is its invariant mass which is zero for a photon.

Light is composed of photons and photons are massless. So light has no mass.

But thing is experimentally it has been proven that photons have energy and momentum inspite of being massless.

U will know e=mc2 which means energy is the same thing as mass except for the conversion factor C2.

So wherever there is mass there is energy and wherever there is energy there is mass. That is mass is the same thing as energy. ( Dual nature of matter )

Using that , photons have energy so they have mass which is known as " relativistic mass " .

"Relativistic mass " is not the same thing as " mass ". It is mass equivalence of a given amount of energy. One cannot weigh it practically , but they show the effects of mass.

A stone has a " rest mass " or " invariant mass " of say 1kg but photons don't have rest mass ( invariant mass ) because they are moving about at speed of light and cannot be brought to rest unlike a stone etc to measure it's mass ( weight ) at rest.

Conversely if photons had rest mass / invariant mass of say 1 kg , at speeds of light which photons actually travel the 1 kg mass will become end up increasing infinitely which ain't possible according to e=mc2 , the energy then required to move the 1kg photon ( now increased infinitely ) will be infinite.

U might ask if light is massless then why is it affected by gravity ?

The answer is because photon though massless ( zero rest mass ) travels at the speed of light , any massless particle if it travels at speed of light , will get effected by gravity , since at speed of light photons or any massless particles behave as having mass due to mass energy equivalence.

U see scientists r still confused when it comes to massless particles moving at speed of light, majority consider photon to have no rest mast but some say photons have a small rest mass but that assumption again ends up nullify other established behaviours and leds to breakdown.

Irony is scientists have yet to determine weather photon is a wave or a particle , the fucker messes everything up by exhibiting both behaviours much to the dismay of all grin

I wish the so called alleged god's instead of handing down the so called alleged books of knowledge had atleast the foresight to pass down some light on photons grin

Just after big bang it was very very hot and there was abundance of radiation with lot of subatomic particles ( which had rest mass ) including light ( photons which don't have rest mass ) , the sub atomic particles inspite of having mass ( rest mass ) was accelerated to speeds close to speed of light , and they cumulatively and primarily were responsible for generating intense gravitational fields then.

Later ( short time after ) as everything started to cool , the sub atomic particles came under the influence of the generated gravitational fields to smash into to each other to create elements which again smashed together to create mass or matter , which again based on the mass created their own gravitational fields to form galaxies , stars , planets etc.

Interesting point to note at the initial point of big bang gravitational field was to due sub atomic particles accelerated to speed of light together with photons which originally travel at speed of light.

Later gravitational effect was predominantly generated by massive coagulation of matter in space.

Gravity is still not well understood , different models give different reasons for existence. Latest is the concept of graviton.

Best one limits to Newtonian physics , it's simple to understand but limits ones options severely.

Once u move to general and special relativity and quantum mechanics and other fuccckery everything gets confusing as hell.

This FC-1 / JF-17 is carrying two CM-400AKG standoff supersonic anti-ship missiles. It's the export version of the Chinese YJ-12.

Wikipedia:
The CM-400AKG is an air-launched supersonic surface attack cruise missile, believed to be the export version of the YJ-12.[19] The 910 kg (2,000 lb) missile is 0.4 m (1.3 ft) in diameter and has a range of between 54–130 nmi (62–150 mi; 100–241 km) while carrying either a 150 kg (330 lb) blast or 200 kg (440 lb) penetration warhead. It has three guidance options, including inertial navigation system (INS) coupled with satellite positioning to get within 50 m, an onboard IR/TV seeker for terminal guidance and 5 m accuracy, and passive radar to supplement the seeker, which delivers (strangely worse) 5–10 m accuracy. One unusual characteristic is that it does not fly at low altitude to avoid detection, but rather uses “high altitude launching” to achieve “higher aircraft survivability.”[20] It may have a top speed of Mach 5.

Wikipedia has incorrect information ,

The CM-400AKG is an air-launched supersonic surface attack ballistic missile not a cruise missile.

A cruise missile has a air breathing engine which is not present in CM-400AKG.
