I'd like to see Sharkee and Michael from Vsauce make a video together.
That would be the ultimate science video for sure. :-)
Yes!!
If that happens they need a new channel like
Sharksauce
+Lieutenant Lynx "Hey! Sharkee here."
+Lieutenant Lynx Vsauce never stays on one topic for longer than a minute, Sharkee is definitely a lot better if you want to actually learn something and *understand* it.
yes i can finally have a visual aid to show how relativity works for my friends.
"You could make cupcakes out of it."
~Sharkee 2016 on space-time.
+Tom Bridges LOL
Mmmm... reality cupcakes...
Sharkee: "Hey man you wanna race?"
Light: ......
Light is like " I am the race"
Light would say "No time" :D
Sharkee is the new Vsauce...
+yashouberry I should go Bald.
Jup
+yashouberry Remember when Vsauce videos were 2 weeks apart? those were the good ole days.
yes
I think he's an additional voice :) Michael is still relevant.
Love to see you back and better then ever Sharkee!
How do you make a cupcake out of space time?
+Cody'sLab You poor some liquid nitrogen on it, then mold it into the shape of a cupcake and poor molten plutonium onto it before it can revert it's shape back into space-time.
+Cody'sLab glad to see you here mate!
+Cody'sLab
You have to be in the 5th dimension before space-time properly mixes with flour and eggs.
+Cody'sLab First you have to invent the universe
+Cody'sLab Do you even space time?
your videos kick ass, especially since you take your time to post them
What do you guys think? What is the fastest thing?
+Sharkee Light?
causality
+Sharkee consciousness
+Sharkee Sonic?
+Sharkee or possibly bruce lee
Sharkee's videos are by far some of the most entertainingly informative videos I've come across on youtube. Thank you for your great videos.
Your jokes are so funny, plus every video of yours is so well made! I started watching about 3 years ago and I'm still super excited when you upload a new video.
PS: Many of your videos had emotional impact on me. (like the "What if We Never Travel Faster Than Light?" made me cry). Please never stop making videos.
your accent is brilliant! I want it :D Also thank you for the highly interesting video :) Keep making videos.
All the best from Italy,
Wolfgang Dibiasi
Love the conductor dance on the red rocket.
Very informative video~ content like this is why I initially subscribed, and I get exactly what I asked for.
This channel deserves a lot more subs!
proud of you Sharkee, keep it up!
Awwww yes, finally, I've been waiting for a new video!
Nice video like always man, you have grown so much from your first video but your quality was always top notch haha. Keep it up man!
I lost it at the observer chillin' near the black hole's event horizon! XD
Sharkee I love your videos, man. Can you tell us something about yourself, such as your education, what you do for a living, etc.?
Bad news and rumours sometimes seem to travel at superluminal speeds.
God damn I love this channel. I wish you'd produce more but I truthfully learn something every time I watch an episode. Keep up the great work:)
One of the best videos i've seen on this channel! Gr8 work sharkee.
A new awesome video! Good job Sharkee, you deserve a lot more than 56000 subs. Keep up with this great work.
This was by far your hardest-to-fathom-video to date! :)
Thank you...
I'm always excited to see a new Sharkee video. You make me want to go back to school to study physics.
You hurt my brain in a good way
Hey, vsause, Indian Michael here, and as always, thanks for watching
He's not Indian tho
She is independent Ann-Michael
Awesome, as always, your videos are like a visual poem to me.
You're the man Sharkee, lovin these videos
A new Sharkee video!
great job. Loved this. The speed of light has always fascinated me. I understood you just fine. Time is never in the mix when watching space-related movies
Great video like always. So simple but in depth also :D
As per usual, awesome job! Keep it up!
very interesting video, sharkee you are excellent at what you do
Awesome, thanks for the video, it answered many of my questions.
You deserve so much more subscribers
awesome channel...!!!!
love it...keep em coming @Sharkee
that's easy.... me after eating White Castle's heading for the bathroom.
+Willems Pierre KFC Bro.
Keep up the good work!.. simply amazing content.
Thank you for the explanation video.
You're amazing mate! Love your stuff. I don't think it's fair to keep comparing him to other YTbers. But I do find this channel to be such an interesting example of how there's something beyond quality content that makes a channel big (perhaps it's just a group of followers who want to share the channel all over the place - who knows). What are your thoughts Sharkee?
+Zero To One Project My other theory was to do with the idea that your clothes are always the same and that's why people aren't sharing your stuff lol. The old clothes bias thing hahahaha.
Your Video's are as always great! this is a great video again :D!
The ratio of likes to dislikes say volumes about how well this video works. Keep posting Sharkee.
Your content deserves more views...
Amazing video! as always! :D
I'd like to point out that the universe is like the earth in the sense that you could travel around it (Going really fricking fast) and end in the same place, so if Earth was Britain, then the furthest planet would be Australia. Now imagen going to someone who thought the Earth was flat, and try telling them, the furthest country from Britain is Australia, AND Britain is the furthest country from Australia, despite there being other countries in all other directions. That is how we can also be the furthest planet from the furthest planet.
UNless the universe is completely flat(witch the odds of are basically zero) then my statement is true. Reactivity, the most well proven theory, predicts curved space.
Actually, all observation shows the universe to be relatively flat.
Yes, but you would have to measure the universe to infinite precision to say it was absolutely flat.
As Chris Smith said, current measurements actually show that the universe is flat, (which would also suggest an infinite universe) but there is a margin of uncertainty.
Yes but the friedmann equation would suggest that this margin of error would result in a slight negative curvature in 4D space time.
I always feel so much smarter after watching your videos. Thank you so much for them. :-)
i love learning. your videos are great. this one especially blew my mind. I had never considered that the expansion of the universe causes far off light to never be able to reach us. that raises so many other questions for me that i want to have answered and understand.
Dammit Sharkee, your videos are awesome. You deserve more love. Give him more love, youtube!!
Love these videos!
I don't know if you know what a "red rocket" is, my friend. Actually, just forget I mentioned it.
now that I realize I can watch more vsauce type of material again I'm extremely happy!! You got a sub and a recommendation to all my friends!
I just realised that the light that is being emitted from the galaxies that are travlling away from us faster than light can only be observed if we travel towards it. This means that if we reach a certain speed we can see the galaxy rotate! Wouldn't that be awesome. Real time timelapse ;)
Kitten Lover I know, but if we find away around the restrictions. With for example a warp drive we could theoretically do this. Just imagine if an unbelievably massive object rotated like it was toll toy. What you see isn't what you get.
what a thought.. every day I am eagerly waiting for your Video.. and today you nailed it. must appreciated for sharing
I love your videos sir, Hoping for your success :D
Wow!!! What a great video!! Thx :-) Good work !!
I actually had a laughing fit at 9:52 XD keep up the good work Sharkee :)
Sharkee back at it again
Space itself is the fastest thing because the speed of light exists inside of space therefore space must be moving faster in-order for something like light to exist inside of it.
i really really .. like your videos .. keep do what you do !!
Your amazing and the smartest person I know ,you awenser a lot of my questions
at 7:22 the action you're describing almost seems like a magnetic field which the top and bottom circuit could be happening i don't know if there's any connection but there might be
what's your input on quantum physics?
i love that you dont have an intro. you are nog wasting time. great. keep uploading consistently to get more subs
Sharkee, my friend, I've a few questions: if the fabric of space itself is expanding, what is it expanding into? if wormholes are funnels of spacetime (not energy) connected to another location in space, what do you consider the hole in the funnel itself? is it space too? they all seem paradoxical to me. and what of gravitons? if force carrier particles of gravity exist, should they debunk the existence of wormholes because gravitons are the force that curve spacetime?
Another fantastic video, Sharkee.
Consider two objects which exist within an expanding zone of space/time, but have zero velocity. Are these objects moving? Would you say they have a speed? Or is observed movement enough?
expansion isnt actually making things move away from us, its just making tje distances between them much greater
+vh2k Imagine two spaceships traveling in parallel to each other. They have the exact same velocity. As such, the relative velocity between them would be zero. If spacetime were to suddenly change for both of them in the same exact way, I'd imagine they would still have zero relative velocity. But if it's possible that spacetime changes for only one of them, then I'd imagine one ship will start moving away from the other, and each ship will judge the other one to be moving away.
We're already kind of doing this with far away galaxies.
Another great video!!!!!
Great video!!
@Sharkee I love your videos I am subscribed and I appreciate all the work you must put into them. I wanted to ask If you might consider choosing a different color for your background in future videos the all white background is hard on the eyes and can give me headaches sometimes and at others It can keep me awake if I try to watch late at night I am really sensitive to light at times well anyway thanks for all you do and the great work.
It's amazing to think about how much "reality" is determined by your perspective.
Sharkee, regarding the graphic of black dots on a grid simulating an expanding Universe, wouldn't a shrinking Universe (where matter loses mass at a steady pace) produce the same result? Has anyone considered this possibility of a Universe where Matter shrinks in a static bubble of space?
I'm no good at theoretical physics on this level, I just have to sort things out..
Velocity is a projected in 3 dimensions of motion, and is a function of time.
It would make an object travel XYZ distances over time T.
Adding the fourth dimension, the object would travel XYZT over... All possible timelines? Is that a thing? A fifth dimension?
What's even more confusing is: If you are able to move across 4 dimensions, as a function of a fifth, what stops you from moving across 5 dimensions as a function of a sixth etc.?
Pretty sure I didn't ask for theoretical physics with a side of cyanide. I'm flipping the table.
Hi Sharkee ,
Why at LHC they are colliding atoms or protons..or electrons which travels in opposite directions at 0,9 c ? why they are not simply smashing atoms against something static ?
thank you
The energy expended to accelerate the particles is what is interesting. When they collide that energy determines what happens. It's not the speed at which they travel that matters per se.
That last part I think might be wrong. That we would be the fastest thing relative to that planet or w/e.
I'm wondering , if you're in a space ship somewhere between te stars not following any of them like the sun we are currently in orbit around, could you decelerate your relative distance to the fabric of the universe to 0. usually when something is standing still we mean it's standing still relatively to another object, but what if had a sphere made of very sensitive redshift/blueshift detectors and a light bulb in the middle, could you use light, which is moving at a constant speed relative to the fabric of space time, to measure your actual speed referenced to the spacetime continuum itself instead of references to an object within it. maybe this way the generation of new space can be measured and patterns of emergence can be found
when i think of the expansion of space i think of something like this:
imagine a flat plane with grains of sand closely and equally distributed. The plane gets stretched like a rubber band and the grains(representing planck length) get further away from each other. As soon as a grain of sand fits between two others it gets filled in. Space is created this way everywhere at the same time.
This explanation of relative time observance comes to you from a guy who hasn't figured out that you can't be one of three twins...
HE'S BACK! !
You amaze me Sharkee!!!
would be cool to have a theory where individual atomic particles are stationary in 4d, traveling unknowingly inward and the only 3d info from this stream is the section that is charged. any thing past this charge is the expanding particle unobservable to humans who are essentially an enigma of electromagnetic cause and effect recording only what electrical signals reach our senses. maybe this unreachable stream that isn't charged and is expanding could account for the expansion of the universe, if every particle has this charge traveling inward at the same rate, we would never know... because we are relative to what we observe. just my weird thoughts.
IM SO GLAD YOU MENTIONED INTERSTELLAR is my favourite movie!
Hi Sharkee, how would a warp drive actually travel faster than light? In order to travel it would have to shrink the space ahead of it and expand the space behind it. Or in reverse. However in order to synchronize the shrinking of the space ahead with the expansion of the space behind doesn't it have to send synchronization information from front to back or back to front. If so, will not the transmission of such synchronization info be limited to the speed of light across the length of such device? Therefor will not the speed of such a device be limited to speed of light?
+Anon Ymous Quantum mechanics could get around this buddy.
+Remy NeoJaff How?
+Anon Ymous if you reveal the identity or state of one quantum particle the other is automatically revealed no matter the distance. This means the information travels faster than light - it's instant. The practicalities are hard.. I'm just saying it is possible to get around this though.
+Remy NeoJaff if quantum entanglement is viable possibility why then bother with wrap drive? why not just go for entanglement engine aka teleporting. however my point being, leaving the uncertainty of quantum world and improbability of quantum entanglement aside, warp drive can't possible travel faster then the speed of light for above mentioned reason. wrap drive traveling at FTL is just a sifi myth/paradox not a sifi possibility.
+Anon Ymous I can't seem to copy any portion of you comment. anyway, you stated the issue with synchronisation, I gave you a scenario where in a small place like a ship that needs immediate communication quantum mechanics, entanglement would allow instantaneous communication and therefore the synchronisation would be perfect. furthermore quantum computing is much closer than you think.
me. I got here first.
These expansion videos blow my mind every time I think about it! We are the center of the universe. My consciousness is the center of the universe. So is yours. Infinite choices in all directions.
I say everyone should drop what they're doing to get together working on this wormhole project..
Depends on the topic;
Fastest thing on land: ThrustSSC - 760 mph (1223 km/h), approximately 0.34 km/s; achieved in 1997
Fastest thing on water: Spirit of Australia - 318 mph (511 km/h), approximately 0.14 km.s; achieved in 1978
Fastest thing in air (unmanned): HTV-2 - ~ 13 000 mph (~ 21 000 km/h), approximately Mach 20 or 5.88 km/s; achieved in 2010
Fastest thing in air (manned): North American X-15A-2 - ~ 4520 mph (~ 7270 km/h), approximately Mach 7 or 3.13 km/s; achieved in 2004
Fastest spacecraft (unmanned): Parker Solar Probe - ~ 213 000 mph (~ 343 000 km/h), approximately 95.33 km/s; achieved in 2018
Fastest spacecraft (manned): Apollo 10 CSM - ~ 25 000 mph (~ 40 000 km/h), approximately 11.11 km/s, achieved in 1969
(Various other records)
In Quantum Mechanics: Quantum entanglement is king, action propagates instantaneously. In General Relativity space itself can move much faster than the speed of light, as in Cosmic Inflation when the Universe expanded by a factor of 10 to the 60th power in less than 10 to the -30 seconds.
How the hell do you still only have 50k subs!? Seriously!
ik i always wonder that. In another universe im sure he has more than Vsauce.
But if the space between us and an object 19bn light-years away gets stretched as well but the delta of the stretch speed is declining, the light will indeed reach us - unless that expansion is constant or even accelerating. Last thing that I read is that it is actually accelerating, thus therefore reducing the distance we can observe with every second - or km/mile of expansion.
Fascinating
The fastest thing is how much sleep I get because of how long I'm waiting for your videos.
Sonic is the fastest thing alive.
ua-cam.com/video/DijbNb3woSc/v-deo.html
just a quick question. just because the farthest thing away from us would be the fastest thing to us, couldn't there be a different fastest thing in that (the fastest planet's) perspective. what if there is something further away than us? in terms of the furthest planet's perspective
This was awesome
Amazing video :)
Here is something that puzzles me. Regarding a Minkowski diagram it is easy to see that anything traveling faster than the speed of light would be regarded as traveling backwards in time according to the ad adequate reference frame. I don't thing there is any need to comment on the absurdity of this possibility.
Now, as long as the stretching of the space-time fabric happens isotropic and outwards, I see no problem. But any kind of stretching/shrinking/deforming of space-time in any way that allows for a "shortcut" between two points, would be seen from the perspective of the "longer path reference frame" as a way of getting from A to B faster than light, thus somebody else would see It traveling backwards in time. Should we not conclude from this that any deformation of space-time fabric is limited in such a way that the straight line between any two points can not be of different interval if measured according to different reference frames that are not moving relative to each other?
Sharkee rockin the dad jeans!!!
nice one
But that star or small rock or whatever,can't actually be the furthest thing, because there are probably also things the same distance away in any other direction. Similarly, we cant be the furthest thing from that point, because then if the earth or the solar system or the galaxy or whatever is the centre of the circle, then that object would have objects twice as far away. Therefore, there can't actually be a fastest thing, unless you're willing to say a non-existent edge is that furthest thing. So I guess the universe is the fastest thing.
+minimooster Agree, this is what I was going to say, but you were faster than me ;-)... Since we know there are other planes, galaxies, clusters in all directions around us, the farthest "thing" from us, has at least the 13.5 billion behind us moving faster than us.
You deserve more subs!!!!!!
issen't the 4 dimenision thing flawed? since the first, the second and the third dimension all experience time, you coulden't say that time it self is a dimension on it's own, it's something that is contained in every dimension, or am i missing something?
The dimensions don't experience time, they're not physical things. It makes perfect sense to think of time as a dimension on its own, there are lots of cases where you would want to keep track of something over time and you don't really care about its position. Fundamentally, a dimension is just a label for knowing where an object is. Imagine trying to invite someone to a meeting: you would obviously have to tell them the 3D location where you're meeting, but thats not enough, you have to tell them the time too.
Of course, relativity is weird because it allows things to move differently through time, and allows time and space to be mixed together, but those things are all logical consequences of a few pretty basic observations and axioms.
