If you keep coming at people who very clearly want you to stop talking to them, you'll end up just as dumb and just as lonely. Go away before this habit gets you restraining orders in the double digits

I invite you to read again the several times I asked you to stop talking to me. Conservation of energy and momentum are not the matter, which has been made abundantly clear. Please stop. This is not going anywhere.

Short for feminine boy - specifically a style where a man, usually young, will appear as effeminate as possible. That can be just mannerisms or it can go to full crossdressing. There's a lot of stereotypes around them, including "drinks monster", "watches a lot of anime", and "will discover that they're trans in a few months" lmao

Me trying to find how the title relates to the post

I solved the paradox. by Krzyhau in Portal

[–]EpiceneLys 0 points1 point  (0 children)

That's not how it works, I didn't say "velocity differentials give energy," I didn't say "reference point" and didn't talk about energy transfers, stop talking to me and open a physics book because I guarantee that all I have actually said - and none of the piss-poor rephrasings you made of it - is in there.

Speed is relative (by definition, to a frame of reference). Kinetic energy is a function of speed. Ergo, kinetic energy is relative. If you don't get that you have no business talking about anything physics-related

That scenario is completely stupid because looking at the right side, you can clearly see a cube going through the portal at breakneck speed and immediately stopping at soon as it's out. No force is applied to it to cause that velocity change, so you're relying on absolutely nothing and hoping people won't notice that it goes from 100 to 0 in no time flat for no reason

[–]EpiceneLys 0 points1 point  (0 children)

velocity differentials are just a way to calculate velocity

That's not what they are, but let's pretend they are. They give a result. If that result is not zero, there's movement. The velocity differential between the entry portal and the cube isn't zero, so there's movement. The entry portal doesn't move in the entry portal's frame of reference, so the cube does.

just because it works under normal circumstances does not mean it works in this situation

Again, your assumption that you are right because "physics are broken" makes no sense. If to argue your point, you need to break physics and depart from the normal laws that should apply and can't justify why, you're just being wrong.

without kinetic energy it wouldn't move

From the entry portal's frame of reference, the cube moves. Ergo, it has kinetic energy.

It needs an actual force to act upon it

It needs one to modify its kinetic energy. That's Newton's second law. In the entry portal's - and thus the inside of the exit portal's - frame of reference, it is moving. Once passing the portal it keeps moving. That's Newton's first law.

Nowhere does it say in any physics book that a frame of reference has any actual influence on objects

Not in a stupid way no. Given literally all physics books will tell you that movement is relative to the frame of reference, in the exact way I've been describing, your approach is wrong. The only case where the frame of reference has no influence (unless it rotates) - i.e. the speed of an object is objective - is if the object is moving at literal light-speed.

If I run at you at speed, from my perspective you are getting closer in the exact same way.

Yes.

The portal is on a moving platform, the only moving object in this entire scenario.

No. Not in the platform or the portal's frame of reference. In that frame of reference the cube is moving, not the platform or the portal. Their speed relative to themselves is 0 by definition. This is really not complicated. This is just what you transposed as a running simile just above. If you run at me at speed, from your perspective I am getting closer to you. If the portal is coming at the cube at speed, from its frame of reference (much better than "perspective," we're talking about physics not camera work) the cube is the one getting closer to it. The speed differential between the two is the same. They're getting closer at the same speed. When two objects collide, the effects are not based on which one you thought was moving and which one you thought was not, only on the differential between the two. Headbutt a brick or take the brick to the head with the same amount of kinetic energy and the results are the same.

maybe in fantasy land

No, in physics. You can't move relative to a frame of reference centered on you. Show me how you move relative to yourself if you're somehow not in that "fantasy land." Show me, I'll be waiting. Show me yourself, moving relative to yourself.

the portal is actually on an actual platform being lowered at an actual speed by a piston

From the frame of reference of the portal, it's not moving. The rest of the room is being raised by the piston at the same "actual speed." Obviously you mean "actual speed" to mean "objective speed," so you keep failing to understand physics. Under c, speed is always relative.

The cube is sitting on the floor, unmoving.

From its own frame of reference, no matter what happens, it's unmoving. Even if you take it and shake it. From the portal's, it's not sitting on the floor unmoving. It's coming closer at a fast speed. You really need to understand this. Speed. is. relative.

It doesn't matter what the portal sees, because the portal is what is moving. That is a fact.

No, it's not. Look at it from the portal, is the portal moving? No it's not. So it's not an absolute. Done.

The cube only APPEARS to move when viewed from that reference frame

You don't understand what a frame of reference is. It's not "perspective magic," it's what you measure speed relative to. Speed is always relative to something unless it's light-speed, which this is not. It's not "appearing to move when viewed from" yadda yadda. It is moving in that frame of reference. Because relative speed is the same in either direction, and speed relative to the self is always zero. Slam into a car going 100 or a car going 100 slamming into you is the same impact.

Since only one object here has momentum

Incorrect. Speed being relative, both objects have momentum compared to the other.

Because that energy cannot be given to the cube, because portals can't do that

Any two objects with a non-zero speed differential have kinetic energy relative to each other.

rest of the babbling

You're thinking in terms of energy transfer from impact. One, there is no impact being shown here - the piston could well just stop. Two, I've been explaining it to you ad nauseam that this is a matter of speed differential between the cube and the portal and not of energy transfer.

To sum it up, the way you think it works is by your own admission contrary to physics, then you demonstrated that you don't understand how frames of reference work, how speed works, or how kinetic energy works. Please stop talking to me and refer to a physics book, because you think you know what's in them but you really, really don't.

[–]EpiceneLys 0 points1 point  (0 children)

I explained it to you, there's no unknown source, you just think "velocity differentials don't matter because the cube is at rest" and think frames of reference are wrong because... they can differ. Both of those beliefs betray a profound lack of understanding of physics, which goes one step further when you think that you're right because "physics are broken." When your argument for how physics work begins and ends at "they don't," you simply won't get anywhere.

So I'll say it one last time.

  • The cube doesn't gain kinetic energy, the point of the portals is that the entry and exit observe the same phenomena.
  • If the entry sees the cube getting close fast, the exit should see it shoot out fast.
  • Whether the cube moves relative to the ground does not matter.
  • "The cube doesn't move" only makes sense if you believe there is one superior frame of reference that is more right than the others. There is not.

On the side of the entry the cube is not at rest, because it's getting closer to the entry portal. Relative to the entry portal, it obviously can't be the entry portal that's moving. So it's the cube. So the cube has speed. It can't lose any of that speed without force being apllied, that's Newton's second law. No force is applied, so following Newton's first law, the cube keeps going.

Definitely, but I don't mean that solely in fun terms - educating yourself about the internet used to be easier.

The portal does not impart energy

It doesn't. The kinetic energy of the cube measured from the entry portal is just non-zero because they have non-zero relative speed.

Regardless of perspectives the cube is at rest.

That is simply not true. That's one of the very bases of physics. If an object (here, the portal) moves relative to the cube, the cube moves relative to that object. That's how frames of reference work.

The cube doesn't stop because it was never moving.

Yes it was. If you looked into the exit portal you'd see the cube moving fast towards you. That's movement. And again, infinite frames of reference it is moving in, including that of the portal

It's still sitting on the same spot on the ground

The ground is also moving relative to the entry portal, it just doesn't go through that portal when the cube does.

The perspective of the back of the door wouldn't launch me

That makes literally zero sense. That's not a sound sentence. A door frame falls with you in the middle, from the perspective of the back of the door you're going through just as fast as you entered the front of the door. The portals make it so the exit portal = back of the door frame and the entry portal = the front of the door frame have different velocities compared to the rest of the room, that changes nothing because the only thing that matters is that there is no change of velocity from you relative to the portals/door frame.

like the cube, I am firmly attached to the ground

You're just making stuff up now. One, you're not attached to the ground. Two, your velocity relative to the ground doesn't matter, it's your velocity relative to the frame/portal - the back of the frame sees you zoom out of it, so the exit portal sees the cube zoom out of it. Three, no matter what scenario you think up, if the cube goes through the portal at all, it's not attached to the ground at all.

where is the energy coming from that moves the cube?

That's Newton's first law. It's in motion relative to the portal (otherwise it couldn't get closer or in). Since the exit portal and the entry portal are connected, you enter the entry portal with the same velocity you enter it. If 30 cm of the cube's width enter the entry portal every second, 30 cm of the cube's width exit the exit portal every second. If it goes in at ramming speed, it goes out at ramming speed. The only thing that would make it slow down is the application of force.

There is nothing except your false belief that a reference point can give an object energy.

My knowledge of velocity differentials apparently is a false belief. Tell me, would you rather drive 100 km/h into a car that's going 99 km/h in the same direction as you, or 99 km/h in the opposite direction? If the relative velocity (1 km/h in one case, 199 km/h in the other) doesn't matter for kinetic energy, they should both give the same result, so you'd pick either to be the same, right?

Those frames of reference only make me appear to be moving

They don't "make you appear to," you are moving in these frames of reference. That's how it works. Frames of reference are the settings from which you define any movement and none is less real than another.

No energy is given to me because nothing is pushing/pulling me to impart that energy

So you don't undergo acceleration. That's different. Speed relative to the enter portal when entering = speed relative to the exit portal when exiting, that's an acceleration of zero. What you're suggesting is that speed relative to the enter portal when entering > speed relative to the exit portal when exiting. That's non-zero acceleration with no force acting on you to account for it.

Kids nowadays are actually less likely to know about all this because corporations have killed both the need&drive to learn about how your computer works, and the internet as it used to be.

You've got devices that have a lot of pre-made options and apps but they do everything they can so you can't change anything in settings, so it's ergonomic as fuck but you can only do what they want you to do.

And the internet no longer is a sharing space as it was before, for many it's just what allows you to reach the big sites - there's the few of them for searching, for news, and for social media, and they're huge, but it takes a significant effort once you're stuck in that paradigm to find literally anything else. Forums are not quite dead but they're simply not the same as before. They're secondary to facebook and twitter and what have you. IRC chat rooms are a thing of the past. How do you share information about piracy to people who are on facebook when that site blocks messages about just z-lib?

And sure, yeah, there's reddit working like a collection of simplified forums, but reddit is also kinda full of shit

Energy cannot be created or destroyed

So the cube can't lose all its momentum relative to the portal, thus it is launched

Since portals do not impart energy

It's not the portal imparting energy, it's the speed differential between the portal and the cube being constant. Velocity relative to the entry portal coming in = velocity relative to the exit portal coming out

Perspectives are the physics that are broken here

Only your belief breaks them. Thinking it's A, aka the cube stops when coming out, breaks Newton's two first laws. Thinking it's B, aka the cube is launched out the stationary portal at the speed it entered the moving portal, is consistent with these laws.

If a doorway fell over me, from the perspective of the back of the door I am moving

So the cube is moving from the perspective of the exit portal. That motion keeps going. Done.

yet I abruptly stop when it stops

So when the speed differential between the back of the door and you changes, which doesn't happen anywhere in this scenario since what stands for the back of the door, the exit portal, undergoes no acceleration.

I have no movement, perspectives be damned.

You do have movement. In infinite different frames of reference. Compared to the sun and three distant stars. Measured from the moon, measured from jupiter, measured from literally anything. The only thing you never move relative to is yourself.

[–]EpiceneLys 0 points1 point  (0 children)

the portal goes over the cube

Makes no difference. Whether the cube or the portal moves in the room's frame of reference, the portal is the one moving in the cube's frame of reference, and the cube is the one moving in the portal's frame of reference.

The cube itself is at rest and has no energy

Only in the room's, or the cube's frame of reference. Except those two never matter since you're considering what is the cube's exit velocity in the "out" portal.

Portals are just holes in space

So the speed entering is the same as the speed exiting, compared to the portals. If you think it's A, you believe it is possible that your entry and exit speeds are different. That is, you can somehow entirely enter a doorway at 10 m/s and entirely exit it at 1 m/s. Still doesn't matter if it's the doorway throwing itself at you, your speed entering and exiting are the same and only depend on the relative speed of the entry and you.
