Hi I'm MAKiT, and you may know me from such things as:
MAKiT builds a weapon - ep 1

The slice of pie charity ad read, that goes something like this... "And if you'd like to get a slice of pie for yourself, than may I suggest makit.wtf/charity/ , where you go donate some money to charity and get a slice of pie for yourself, once again that's makit.wtf/charity/ where you can donate some money to charity dbs alliance and get a slice of pie for yourself"
But what not many people know, is that I love science. I mean I do only have a channel, life and all of my personal belongings dedicated to science, so it might've gone unnoticed. Anyhow if you like science, that you are more than welcome to stay. (Also sometimes I build weapons for...
38:31 The top value of the sigma didn't change, so I think this is an editing error note here. (Should've been 4 instead of 3 as for instance, after 10 seconds of this time notation, you'll see that the transformation of the value of the denominator is symmetrical to the top value of the sigma)
I do not comment easily but this type of content is not something you came across normally on this brain-rot I hope platform you reach 10 million sup so you can be recognized for your efforts 😊
Quick question. If you have two particles travelling at just under the speed of light relative to an outside observer and both are travelling in different directions, wouldn’t they appear to travel faster than the speed of light from each of their reference frames?
That's what the time dilation and length contraction is for, basically if you have object A travelling at 99% of speed of light to the left, and object B going at the same speed to the left, the resulting relative speed from the perspective of object A won't be 99%+99%=198%. That's because from the perspective of object A, the time and length is different, so the time will lengthen and the length will shorten to the point where object B will still seem to travel at a speed lower than the speed of light
energy doesn't really exist, something doesn't have X energy really, it's just how much work it can do compared to some frame of reference. in that sense, negative energy isn't much more informative than saying it has less energy than something which has 0 energy. some examples are, gravitational potential energy, which is given by the formula of -Gm1m2/R notice the negative sign. that means, that as long as the distance between the 2 masses being finite, and the mass of the 2 masses being non-zero, an object's gravitational potential energy is negative. an object infinitely far away though has 0 energy. that means that the further away you are the more gravitational potential energy you have, as is expected. a similar thing happens with charges it's possible to charge an object without grounding a side of it, and without expending energy. for example, taking 2 metal cubes and connecting them, placing them near a strongly charged object to polarize the cubes. afterwards, seperate the cubes and you'll have 2 charged cubes with no energy lost. how so? the negatively charged object now has electric potential energy, and the positively charged cube? well, as of convention, it's negative
8:22 Imaginary time could be perpendicular to regular time. The axis you'd need to traverse to move to parallel timelines. Like how the i-axis is perpendicular to the normal number line on the complex plane. Negative just indicates which direction you are moving to along that axis.
Would imaginary time be something like an alternate timeline? I mean i did hear that time travelling can theorically results in the timeline spliting and that's why no time paradoxes happen
For "time being frozen to photons" and time dilation when traveling faster - a neat thing that I figured out that I have not yet seen anyone ever mention: As you use more and more energy to accelerate faster, you can't exceed the speed of light "as seen by a stationary observer", but also to those observers, the time *you* experience stretches... so according to them, you may be able to travel 4 light years, while they see you experiencing only one year of time. And this really works. To you, distances get shorter, and while you don't measure yourself exceeding the speed of light, the distances you measure get short enough that you can in fact reach an object that at the start WAS 4 light years away, in 1 year. And in general, if you use some X amount of energy to accelerate, you will reach an object some distance away in a time that would be predicted by non-relativistic physics, so you will sort of see yourself accelerating exactly as Newton would predict, except that the distances contract, so you don't *actually* go faster than the speed of light. So think about it... relativity seems to somehow conspire to make time dilation and length contraction to make it look as if relativity didn't exist when you try to go faster, except that somehow a journey that may have been 1 year for you lasted 100 years to someone outside. So for photons... they do sort of seem themselves going "infinitely fast", because everything is zero distance away. Regarding imaginary mass - when I tried to think of what imaginary mass would do, I came to the conclusion that it would behave pretty much like electric charge, though I have no idea how to reconcile it with the negative energy
What if you were in a void and could not see any light anywhere and you and a few other objects are traveling along how could you tell if you were going the speed of light or near the speed of light or not? If you and a few other objects traveling along at 99% the speed of light but have no other light sources but your own to judge how fast you are traveling and from your point of view everything seems to be at rest but together you all are traveling at 99% the speed of light. How could you tell if there was no other light sources to judge what speed you are going? what difference does it make if you are the only object traveling through space?
No. You only reduce things to be relative to the full picture. What is actually happening. The cube isn’t stationary, it moves with the rotation of the earth, the movement through the solar system and galaxy and space. The other “1” squares move at a different rate. Equal to earths rotation plus its speed.
before watching anything more than the imaginary time, physics does have that I believe it's called complex minkowski spacetime, but I'm dumb as hell so I can't tell you what it's about exactly (it's more like events in time and the imaginary unit is kinda eh)
8:50 what if we assumed the existence of a second temporal dimension? I mean we wouldn't be able to comprehend it, like how a creature existing with one spacial dimension wouldn't ever be able to comprehend a second spacial dimension, because they don't even have anything else to base it off of, a 2d creature would at least be able to understand the idea of what a 3rd dimension would imply, and we can understand what a fourth dimension would imply, what if we are like the hypothetical 1D creature, except we are unable to grasp the consept of a 2nd temporal dimension?
Math is created physics is created everything is created by GOD is the only thing which is eternal and created the universe GOD can explain everything he is the mean of life and the reason of everything Only pray to GOD REPEAT accept Jesus as your lord and savior by pray simply say Jesus I believe in you and I accept your free give of eternal life please forgive me of all my sins 🙏. Believe the gospel 🙏 😊❤❤
I mean its interesting how everything is so arbitrary I started thinking about it in physics class when I thought about that to tell to potential energy you need a reference point. Of course it makes sense you need something to refer to but doesn't that mean energy is relative? Because if the amount of energy in a system is relative to the forces that determine the potential energy, then it will affect other other types of energy too when it changes state. Does this mean you can say I have x amount of energy relative to the earth, or maybe some other y amount of energy compared to something else?
relativity makes a hell of a lot more sense when you think of it as how much time it takes for one thing to recieve the info of the other. acceleration changes time because it "squishes" or "stretches" the instances of information sending
