    Thanks for watching, Super Nerds! This was a fun one, as many others have talked about these phenomena, but I've never seen the math on how to make some of them "work." See you in Footnotes. -- kH

    @Apakuki Vave First of all, your a genius. And thank you for answers that make sense. I do have some crazy thoughts you can rip apart. A: I believe a black hole is one big fundamental particle that has limit to its size. Thats why(i believe) black holes don't give off any light. B: I also believe empty space is more like a fluid then we think. And this extra mass that scientists are looking for and call dark matter, is really the universe itself. B: Gravity is just the absence of space. Which means, the universe is trying to return to its previous state. Like a ball in water, and the further you push the ball down it would represent higher density and mass.

    @Mein Kamph by 0 speed i assume you mean in relation to what we consider speed in general relativity? All objects in the universe are moving, they move because they have energy (this is a fundamental principle of physics). In order for a physical object to reach light speed you need infinite energy (because as you add energy you are in reality, adding mass, which then requires more energy to accelerate it further).... similarly in order to reach absolute 0 velocity you need to remove mass to the point where a physical object is mass less (something impossible for all particles except photons, which are technically not considered a physical particle). The best example of this is our attempt to reach 0 degrees Kelvin, something that is technically not possible because the matter you are trying to cool, in itself, is energy we can only approach 0 degrees Kelvin like we can approach the speed of light, but it is a barrier we cannot hit. so i guess to answer your question, its fundamental principle of the universe and not strictly bound to quantum mechanics or relativity.

    @Apakuki Vave Is this a value that is added when quantum theory and or special-general relativity is being used? I ask because i don't know, and you seem to have the know.

    @LordofDestruction123 you could also change the parameters to make it a monofiliment, then no matter how fast or slow the blade is moving it would slice through anything.

    @coderhonnybord15 C in a vacuum is a universal constant, hence the speed limit... there is no single maximum observable speed limit, because observable speed is relative... A star ship moving at 99% of light speed would appear to be standing still if i were also moving at 99% of light speed in the same direction or close to 2x light speed if i were moving in the opposite direction.

    Ok but like what if you made the guillotine out of a force and like had that force compel an object. Can't a tangible object be at the 'reference point' that cuts at the speed of light? And like by force I mean like magnets or lasers. As these forces come into contact an object gets accellerated down the cutting edge?

    It's partially wrong because you have to take into account every life on earth. No every singular person in the universe times the trillions. It cannot change everything. Thus the percentage of chance. Steins gate. Any other miscalculation would cause a singularity.

    3:53 so if that's the case how do we know time isn't instant? Do we KNOW that we couldn't kill our pastself? Like as we start to stable our self in the past would the knife and anything we try to touch ourself with at the moment just disappear like theres a black hole bubble around ourself. Protecting the universe from casual breaking? OR is it different. Where we could kill ourself but it would take some time before the universe catches up with us and we then fade away. Because rather then a paradox forming an infinite loop like we normally think. Time is slow and it takes time to catch up even if by one second would be enough. Because then it wouldn't be a loop it would be how u die. There would no difference in u dieing this way or a normal way. Even if the difference was a second for time to catch up.

    The “speed of dark” is an illusion because darkness is just the absence of light. So the shadow would “move” FTL but darkness is technically just nothing.

    I think Vsauce made a video similar to this one in the past. The example he uses for scissors, however is two giant scissor handles 1 light year long each, seperated but moving toward each other, and the cutting point when they pass each other moves faster than light. So rather than apply a force to the to get them to move, which wouldn't travel FTL as you explained, they are independently moving towards each other

    Since special relativity is only valid in an inertial (non accelerating) reference frame. In example of Sirius, special relativity cannot be used by the person on Earth since they are in a non inertial reference frame relative to Sirius.

    Sean C14 hari yang lalu

    Well if you're going to be entirely accurate what you should be saying is that the Universe has a presumed speed limit. As of yet nothing, neither energy nor matter, has been observed moving faster than the speed of light. But at the same time there really isn't any hard evidence to prove that this limit is an absolute value that cannot be surpassed.

    Kinda trying to be a troll, but also, math. Since you calculated the angle at 6 m/s, wouldn't you need to drop it at a height that could achieve such speed. i.e. 0.46m.... just double checking :) (since all masses fall at equal accelerations, and the only determining factor in impact velocity [assuming standard gravitational forces, and a reasonable distance away from earth] is the distance it is dropped) Love the channel :)

    I feel like the cutting blade isn't actually moving faster than light. It's movement vector is still linear at the point of impact--it doesn't actually travel down the angle. Now if you made a rocket-powered space-whip, I'd find that much more... believable?
