Wouldn't the laser beam bend and form a wave, much like a whip does when you flick your wrist? If this is the case, then you have not actually broken the speed of light, because the point on the moon would not instantly move with your hand, just like the tip of the whip doesn't instantly move with the handle.
Even something as simple as a laser pointer had a theoretical 'unlimited' range, although you can only (directly) observe so little.. that it doesn't really matter to most. Since you can't physically record light at that relativistic distance without electronic aid, this seems confusing. It's about the way energy dissipates though space over vast distances. Just because you cannot observe the 'event' directly, does not mean it didn't happen in some way/shape/form. Energy is a strange thing.
I understand that he's saying it is only an image that's appearing to travel faster than light, but it's a completely pointless statement. It's only the way your brain works that makes it look like one moving point. You may aswell park two identical cars next to each other and say that you've made one car appear in two places at once. Or. Pan your eyes across the night sky and pretend there's only one star moving really quickly from place to place making it look like a sky full of stars.
This isn't right at all. This is like saying: if I shoot a paintball at a wall ahead of me at 80 mph, then shoot a second one at a wall behind me at 80 mph, then I made the paint splatter move at 160 mph!
Obviously this is nonsense.
It's not the same paint, much like it's not the same photons hitting different parts of the moon. There is no continuous object so there is no motion.
(Never mind that the time it takes the new photons to travel to the moon > time for light to traverse the surface)
@XaviersAccount Yes, but the individual photons that have already left the pointer are not going to shift from flicking his wrist because they aren't physically connected to the pointer. There will be a delay there which is the constant speed of light. He's usually so very good at his explanations that I'm wary of just saying, "Wrong!" But I will be checking with my physicist buddies at Ga Tech. (p.s. my PhD is not in relativistic physics)
i dont think this is correct think of it like this if you shot the laser at the moon and move it across it seems like its faster however you have to remember that the source of the light if from the laser not the moon. It is traveling from point A ( laser) to point B (moon), so every cm you move the laser on the moon point A to B is still the speed of light not A to B on the moon. The points on the moon technically have no speed because it have no source of light.
Maybe I can simplyfy what he said.Imagine there are two light bulbs, which are 3000000000000000000000km apart from each other.When bulb A lights up, bulb B fades away and vice versa.All of these happened in one second.Apparently,an observer will see a light spot travells at a"image travelling speed" .
This kind of "speed"(3000000000000000000000km/s) is obviously faster than the speed of light.I know this is stupid but fun =p
Easiest way to travel faster than the speed of light.
Go slowly backwards in time. Let's say you need to be 10 light-years away from here in less than a millisecond. The journey would take 200 centuries with conventional fuels. Well, simply start begin to go backward in time with the least energy-expensive fuel you've got. Suspend the crew in time, leave the computers running to allow dodging obstacles.
When you leave, you are minus fuel, and arrive 1 millisecond after you left.
the light doesn't travel faster than light. it's a continuous stream of light that is all. it's not as if you turned it on then shut it off and turned it back on in a different spot. think about it.
DAMN! And i thought that all that "Millennium Falcon" hyper speed were just bullshit. Now i know it can be true. Thanks for the enlightenment. Please explain also that "light saber"...

If you shine a laser at the moon and you flick, the photons still travel at 186k
Its all about relativity, it matters not if you point your laser and flick it at amazing speeds because the photons emited from the laser still travel to the location at 186k m p/h its a constant speed that cannot be changed
Okay this might sound like a bit of a weird question and I might be missing the obvious but...
Suppose you have a solid rod that reached a light minute or so into space and then you flicked it so your hand moved about a foot but the other end of the pole/rod would have traveled maybe a couple of million metres in under a second. Would this hypothetical scenario allow the breaking of a universal speed limit?
@Richardvnd you cant,.. remember, when an object moves closer to the speed limit time goes slower for the object.
This means if someone is running and you are sitting, the running person's time goes slower, of course the slow down is so small that it is almost immesurable.
now lets look at your question.
if the end of the rod goes near lets say 96% light speed,
time would be slowed down EMMENSELY.
if you were standing on the tip of the pole 1 day for you would = 1 year for everyone else.
@Richardvnd No, the rod would simply bend. Even the information that the rod is being flicked travels only up to the speed of light (and in fact very much less for a solid object being moved, more like the speed of sound in the object).
No part of the rod would ever move faster than the speed of light, regardless of what you did.
If you take 2 flashlights and point them in opposite directions of one another and turn them on, they will both shoot photons in opposite direction. The photons from both flashlights will be moving away from each other 2x the speed of light.
@zukodude487987 That's wrong. Speeds actually are contracted, though minute in low speeds, but noticeable in near-luminal velocities. It's special relativity.
@zukodude487987 its only relative to one another , both photons are still moving at light speed, the distance between them is increasing at more than light speed, nobody ever said that distance cant be faster than speed light, in fact we already know galaxies are doing the same thing.
whait...DUDE ! U SOOO WHRONGG!! if u use a lazer thats technically light..your tring to brake the speed of light WITH LIGHT!, its like a water hose.. if you move it the water in slow motion ill bend, the lazer light will bend so ill go the same speed... thumbs up so he can see...
@25Mexx Just watch the video again. It is not the light itself that travels faster then the speed of light. But it the spot of light that moves faster.
But surely once we have displaced the point of light, the light beam will then take the time it would normally take the light rays to reach this new point on the moon. Therefore it would still take the light a certain amount of time to reach this new point even tho you have changed the spot the beam will land on at a much faster rate. You are presuming that the light will reach the moon instantaneously which it will not.
If you could travel the speed of light, you could time travel to the past only. This is because when you see things with your eyes, it takes light deflecting of the object and shining into your eyes, therefore seeing the object. Now if you traveled faster than that light you would rip the vision of the human eye making a black streak in the universe as your time traveling machine. So if you traveled faster than the light, you could see light particles from another time period. Or, see the past.
@Stingler23 That isn't what people mean when they say you can travel into the past by going faster than light. It's down the relativity. As you speed up, time slows for you. If you're standing still rather than driving at 80mph, you're aging faster than the person in the car. Granted, you age about a millionth of a nanosecond faster each year or so, but it happens.
... Now imagine that car is traveling at the speed of light. It's estimated that moving at the speed of light would effectively stop time, so any faster would reverse time.
Only the image moves on the moon, not the actual light beam... This is just the matter of distance over time and the laser beam is practically the speed of light therefore it is just traveling at the speed of the theory as if a wall is 10 ft. away you can move your finger pass that wall in about a second if you stand far away enough.
no information can travel faster than the speed of light. Your argument makes no sense. The spot of light on the moon will not move instantly as you flick your list.
Nice video , everyone check out my channel and give me a shot (Subscribe) . First video comng soon in my channel so i will appriciate if you check the channel . Thanks
this is like saying you've got a 1 lightyear long stick, and 2 people at each end of the stick. one of the guys poke the other guy with the stick, and then the poke will reach him 1 year before light hits him..
When you push on a stick the force is not felt instantaneously on the other side. The force travels at the speed of sound in the stick, which is a hell of a lot slower than the speed of light.
besides, if this actually worked, then you (or whoever thought of it) would be EXTREMELY famous, it would be all over the news that someone proved Einstein wrong and we would all know
ok there is so much wrong with this theory, first off when you move the laser they are different photons, you can't count it as a continuous beam, also, photons arent matter so they don't count, they travel at the speed light anyway
@lucasbudega Wrong : ) Even if this was physically possible(let's assume it is), the forces that are required for the other end of the stick to actually move, work at the speed of light as well. What I mean is, that gravity, for example, doesn't instantly "work". If a new planet suddenly appear a light year away from earth, we would start feeling it's gravitational effect after a year from it's appearance. Concluding: the other point would start moving after about 100 years.
@lucasbudega Uhh, I only just read your previous comment carefully. Not that it changes much, but that's pretty stupid of me. I thought you meant a straight 100 l-y long stick, not a round one. In this case, I'd say that it's a fun question and I have no idea :P although that forces move at the speed of light is a fact, as far as I know, so you have to take this into consideration while thinking about this.
@lucasbudega Ok, then, yes, it would bend somewhat like rubber. Either way, the information would travel at more less(or actually exactly or less:P) the speed of light.
So lets go to the extremes: Imagine a sphere on the sky that has the radius of one lightyear. You point parallel to earths surface and turn around 360 degrees. Lets say you turn around in one second. The first photon will reach the sphere after one year and the last photon will reach the same spot on the sphere at one year and one second. All the other photons are distributed along the circle you've drawn. So "you've traveled" 2*pi*1ly = 6*10^16 m per second = 2*10^8*c >> c. It's troll science!
This is incorrect. The light traveling from the laser would have to get to the moon first before a dot could appear. It's like shooting a machine gun and spinning in a circle. The bullets are limited by their velocity. If you took a picture from above and connected the bullets the line would be a curved pattern. The same thing would happen with the photons.
...the same thing would happen with the photons. You couldn't move the beam faster than the speed of light because the end point of the beam would be delayed until the light arrived from the laser.
Swinging a long pole wouldn't work either. Einstein's E=mc2 proves that it takes too much energy to accelerate a mass up to light speeds. Try it sometime. Take a large pole and a short one and compare how easy they are to wave around in front of you. Now imagine one that goes to the moon.
I've known about this trick and knew that it didn't really break relativity because information isn't traveling faster then light, but I'm still confused about the following hypothetical example.
What if instead of a laser pointer you are holding a 239,000mile long pole with a message on the end of it, and swing the pole from one side of the moon to the other is the same amount of time as the laser pointer. Would this not be information traveling faster then light?
Didn't Einstein say that nothing can accelerate past the speed of light? But it would be possible that something was "born" or created that had a speed faster than the speed of light from the beginning.
@TheOfficialParado in actuality lasers can and do hit the moon from the earth, one of the roles of the first few Apollo missions was to put mirrors on the moon to test with higher accuracy the speed of light.
@eljhm Because there isn't 1 photon that creates an image. The image is the "dot", which is the reflection of a lot of photons reflecting off the moon's surface and back to your measuring device (eyeball).
Actually, you can't break the speed of light using a laser pointer. Think of it as spraying a garden hose in one direction, and suddenly swinging it in a different direction. The water doesn't reach the new destination until a short amount of time has passed. Light acts in a similar fashion; it does not appear on whatever surface it is being pointed at instantaneously. Please correct me if I am wrong. :) Love your videos by the way.
although neutrinos can travel a fraction of a second faster than light, in this scenario in the video, the beam of light from the laser never actually traveled faster than its own speed, (the speed of light), the direction in which it moved may have traveled faster, but the beam itself never did
This is so fundamentally wrong. When you flick your wrist, the photons that are already emitted and on their way to the moon don't change their path and all of a sudden hit the other side of the moon. Basically, the first photon that would hit the other side of the moon is the one emitted AFTER you flicked your wrist. I don't see why you first said that what Einstein postulated was wrong, and then say "So no physical laws are broken", you're contradicting yourself. Nothing can go faster than c.
@RasmusLastname It takes light about one second to get to the moon. It takes the same amount of time to get to the other side of the moon from the same point. so you use the diffference between the times to calculate the speed. Instead of taking 1.00069 seconds, it really takes 0.00069 seconds for the dot of light to move across 3,474.8 kilometers, which is roughly five million km/s. The speed of light is around 300 thousand. Nothing means no "real" objects, dot isn't an object.
Since we are talking about the angular velocity of the spot, at that height, there is dilation of time and contraction of space and the speed of light would remain constant
It' s like defining in your head "the image" to mean the expected image to be printed with a laser jet printer on a sheet of paper and then ignoring the time it takes the printer to print it. The photons will still travel with c, the speed of light limit. My oppinion is that you could actually see with your mind' s eye how you sprinkle your moon back yard with a hose that spreads light, you could see the jet of molecules / photons bending, across space, as time passes. Keep posting, thanks.
Wouldn't the laser beam bend and form a wave, much like a whip does when you flick your wrist? If this is the case, then you have not actually broken the speed of light, because the point on the moon would not instantly move with your hand, just like the tip of the whip doesn't instantly move with the handle.

@zukodude487987 its only relative to one another , both photons are still moving at light speed, the distance between them is increasing at more than light speed, nobody ever said that distance cant be faster than speed light, in fact we already know galaxies are doing the same thing.

whait...DUDE ! U SOOO WHRONGG!! if u use a lazer thats technically light..your tring to brake the speed of light WITH LIGHT!, its like a water hose.. if you move it the water in slow motion ill bend, the lazer light will bend so ill go the same speed... thumbs up so he can see...

But surely once we have displaced the point of light, the light beam will then take the time it would normally take the light rays to reach this new point on the moon. Therefore it would still take the light a certain amount of time to reach this new point even tho you have changed the spot the beam will land on at a much faster rate. You are presuming that the light will reach the moon instantaneously which it will not.
Rcampbell947 2 weeks ago
If you could travel the speed of light, you could time travel to the past only. This is because when you see things with your eyes, it takes light deflecting of the object and shining into your eyes, therefore seeing the object. Now if you traveled faster than that light you would rip the vision of the human eye making a black streak in the universe as your time traveling machine. So if you traveled faster than the light, you could see light particles from another time period. Or, see the past.
Stingler23 2 weeks ago
@Stingler23 That isn't what people mean when they say you can travel into the past by going faster than light. It's down the relativity. As you speed up, time slows for you. If you're standing still rather than driving at 80mph, you're aging faster than the person in the car. Granted, you age about a millionth of a nanosecond faster each year or so, but it happens.
Dannyowen555 2 weeks ago
@Stingler23
... Now imagine that car is traveling at the speed of light. It's estimated that moving at the speed of light would effectively stop time, so any faster would reverse time.
In theory, that it.
Dannyowen555 2 weeks ago
Only the image moves on the moon, not the actual light beam... This is just the matter of distance over time and the laser beam is practically the speed of light therefore it is just traveling at the speed of the theory as if a wall is 10 ft. away you can move your finger pass that wall in about a second if you stand far away enough.
Stingler23 2 weeks ago
no information can travel faster than the speed of light. Your argument makes no sense. The spot of light on the moon will not move instantly as you flick your list.

When you push on a stick the force is not felt instantaneously on the other side. The force travels at the speed of sound in the stick, which is a hell of a lot slower than the speed of light.

I've got a doubt: Picture a 100 light-year long round stick...
If I spin that stick in one point of it, the other point will instantly spin too, so I'd be breaking the speed of light... right ?
lucasbudega 1 month ago
@lucasbudega Wrong : ) Even if this was physically possible(let's assume it is), the forces that are required for the other end of the stick to actually move, work at the speed of light as well. What I mean is, that gravity, for example, doesn't instantly "work". If a new planet suddenly appear a light year away from earth, we would start feeling it's gravitational effect after a year from it's appearance. Concluding: the other point would start moving after about 100 years.

@lucasbudega but it wouldn't instantly spin, your force to cause it to move travels down the stick at or slower than the speed of light.

So lets go to the extremes: Imagine a sphere on the sky that has the radius of one lightyear. You point parallel to earths surface and turn around 360 degrees. Lets say you turn around in one second. The first photon will reach the sphere after one year and the last photon will reach the same spot on the sphere at one year and one second. All the other photons are distributed along the circle you've drawn. So "you've traveled" 2*pi*1ly = 6*10^16 m per second = 2*10^8*c >> c. It's troll science!

This is incorrect. The light traveling from the laser would have to get to the moon first before a dot could appear. It's like shooting a machine gun and spinning in a circle. The bullets are limited by their velocity. If you took a picture from above and connected the bullets the line would be a curved pattern. The same thing would happen with the photons.
mrwoodscience 1 month ago 3
...the same thing would happen with the photons. You couldn't move the beam faster than the speed of light because the end point of the beam would be delayed until the light arrived from the laser.
Swinging a long pole wouldn't work either. Einstein's E=mc2 proves that it takes too much energy to accelerate a mass up to light speeds. Try it sometime. Take a large pole and a short one and compare how easy they are to wave around in front of you. Now imagine one that goes to the moon.
mrwoodscience 1 month ago
I've known about this trick and knew that it didn't really break relativity because information isn't traveling faster then light, but I'm still confused about the following hypothetical example.
What if instead of a laser pointer you are holding a 239,000mile long pole with a message on the end of it, and swing the pole from one side of the moon to the other is the same amount of time as the laser pointer. Would this not be information traveling faster then light?

@eljhm Because there isn't 1 photon that creates an image. The image is the "dot", which is the reflection of a lot of photons reflecting off the moon's surface and back to your measuring device (eyeball).

Actually, you can't break the speed of light using a laser pointer. Think of it as spraying a garden hose in one direction, and suddenly swinging it in a different direction. The water doesn't reach the new destination until a short amount of time has passed. Light acts in a similar fashion; it does not appear on whatever surface it is being pointed at instantaneously. Please correct me if I am wrong. :) Love your videos by the way.
darkfrozenwater 1 month ago 3
although neutrinos can travel a fraction of a second faster than light, in this scenario in the video, the beam of light from the laser never actually traveled faster than its own speed, (the speed of light), the direction in which it moved may have traveled faster, but the beam itself never did
mike81403 1 month ago
This is so fundamentally wrong. When you flick your wrist, the photons that are already emitted and on their way to the moon don't change their path and all of a sudden hit the other side of the moon. Basically, the first photon that would hit the other side of the moon is the one emitted AFTER you flicked your wrist. I don't see why you first said that what Einstein postulated was wrong, and then say "So no physical laws are broken", you're contradicting yourself. Nothing can go faster than c.
RasmusLastname 1 month ago
@RasmusLastname It takes light about one second to get to the moon. It takes the same amount of time to get to the other side of the moon from the same point. so you use the diffference between the times to calculate the speed. Instead of taking 1.00069 seconds, it really takes 0.00069 seconds for the dot of light to move across 3,474.8 kilometers, which is roughly five million km/s. The speed of light is around 300 thousand. Nothing means no "real" objects, dot isn't an object.

Since we are talking about the angular velocity of the spot, at that height, there is dilation of time and contraction of space and the speed of light would remain constant

It' s like defining in your head "the image" to mean the expected image to be printed with a laser jet printer on a sheet of paper and then ignoring the time it takes the printer to print it. The photons will still travel with c, the speed of light limit. My oppinion is that you could actually see with your mind' s eye how you sprinkle your moon back yard with a hose that spreads light, you could see the jet of molecules / photons bending, across space, as time passes. Keep posting, thanks.
