  • The environmentalist morons should have a a hay day with with. They are plastic! Good lord ppl are hypocrites

  • Isn't the Ozone layer supposed to absorb all the UV light coming to Earth? This should make the entire footage completely black. Or is this the sign of depleting ozone layer?

  • it's not a pattern if it doesn't repeat. So, there could never be a pattern that doesn't repeat. I am going with the literal meaning of pattern here

  • Its it's it's pretty really very very amazing😎

  • Actually the lines are also forming

  • i am reading many Drew comments.

  • Stop with the hate comments, I can’t like em all 😏

  • Make two satellites. You can make a powerful Laser that can reach to moon from satellite in our space or powerful Laser even to satellite near mars or sun (for distance) . Install a clock on both satellite. Make it such way that clock can be stopped by the same laser. Start count down at both clock at same time when both satellites are on earth. Send them to space. Then when you fire one laser it will stop the clock and when the lazer will hit another satellite it will stop the clock there. Now you know the distance between 2 satellites.. Know how much time it took to reach lazer from one satellite to another and time is also synchronized because both clock was started at same time and one stopped while firing the laser and another stopped when laser light detected... And space is vaccum. Only defects if any space objects comes in middle of two satellite and obstacle lots of money

  • What you said about the cat is was kinda easy EXAMPLE-you have a box you think there is 10 $ in it but until you open it it there could be no money or 5$ or 10$ the . Lol I think about this a lot not joking 🙃 .oh ya I am just 12.and what he meant by measuring one will collapse the other probability is that since you measured it ,it happened if he had not measured it it could have changed and a new result could be the outcome so unless you mesure /know something it is not real.if this does not make sense pleases comment.and different realities are just thing that you or me do different they creat different universes where you do things different .

  • SAT's be like 💀

  • Bifurcation or Dichotomy?

  • If you perfect this, you could capture sound with a telescope

  • Why did you have plastic surgery?

  • Could we measure the speed of light by slowing the light ? If so, we could measure it using not-slowed light to launch the signal for measurement over a small distance, which will have a small speed difference on both side, but would be negligable. I know that light speed change according to which matter it goes through, so we could use water for example. We would need to do more experiment to see what is the difference with estimated one-way speed of light and compare with other material to see if it is proportionnate. I wonder if that make sense...

  • You just proved the main stream physicists wrong. "In an infinite universe things that happen here must happen an infinite amount of times in other places". WRONG. They say that because their math is limited to finite amounts and because they (like everybody) cannot imagine or "grasp" infinity. Therefore - we will continue the wrong way we have chosen. It's sad.

  • 3:08 damn, this dude got kicked

  • Voglio cercare quello che ha tradotto in italiano e stringergli la mano

  • I'm very sure the cashier is expecting a magic trick but it's just pure science

  • @9:50 What if we place the two clocks that need to be synchronised at equal distance from the center clock and then send out the pulse from the middle one? If the clocks are not in sync still then the speed of light must not be equal in both directions.

  • Atleast someone is attracted to me ☺️☺️💚💚

  • Hi Derek, could you please make a video about how our brain makes up things that we don't actually see? for example in low light conditions I thought that I saw something but upon closer look, it is not as what I remembered just a moment ago. Is there a way to train our mind/brain to not compensate for the missing information?

  • *Russia liked this video*

  • Im just thinking about how many apples that is

  • Insulation is the key to bring a greatly reduced energy future.

  • Ok but what about the real life lightsaber

  • Okey this completely breaks my brain.. So maybe this is a stupid remark, but would it make sense to measure the 3-way speed of light? In that case, possible differences won't cancel each other out?

  • The return of light from a round trip can’t be faster than the speed of light so it’s receipt can’t be instantaneous.

  • I'm absolutely goob smacked!

  • Veritasium: "Aerogel is 99.8% air" Lays chips: *cough*

  • 4:39 I hear a Minecraft villager say something.

  • It’s just called a gyro

  • So this thought disturbs me. The thought of an expanding universe, but granted I can understand how our universe is expanding. I see our universe as a black hole, the black hole can be feeding, but it can also leaking hawking's radiation. One process is extremely slower then the other, feeding being the faster of the two. Which means a big bang and expanding of the universe would be a normal event in making a new universe. Also I want to point out I do not agree with a big crunch, I think hawking's radiations explain away the need for such an event. The real problem with what's going on with astronomy, is that we think of the hobble constant is a constant. Depending on which direction your looking at in the sky, it should change. This so called constant should change over time and depending on which direction your looking at in the sky should change due to how the earth spins, rotates, how the sun rotates in the galaxy, and how the galaxy moves. Which at this time we can only really say we have good guesses at a couple of those measurements. Movement is by far the hardest thing to account for in the universe

  • Geez, get the Slow Mo Guys.

  • WIth this information we should be able to create a concrete equation on how much our movement is effecting redshift, why do we not see this equation when calculating the Hobble Constant?

  • I was thinking this the other day when I was watching ghost hunters, they say the past is scratched in to the walls like grooves in a record, so why not invent a machine that can read the walls?

  • Chaos is a ladder

  • Wow.....Mind blown!!

  • I'd really like to read some meaningful comments but all the top comments are just bs. :( Comments should be categorized and let users switch between them.

  • This video for who failed by doing hard work

  • Now. You have mentioned a man falling out of the sky but what about a body submerged underwater? If we didn’t need oxygene could practically “defy gravity” permanently? Just another example how gravity does not exist In the ways society teaches D:

  • My last comment (mental experiment) might not work unless we send EM wave with so high frequency that on slower side (if there is slower side) the information will be lost since it will not fit anymore in time frame while on the quicker side it will be still preserved. Not sure if that is possible. But I think I was on a good track. Frequency is the key. OK, it is correct that we can't measure one-direction speed of light. But we don't have to. We just need to test if light have the same speed in every direction and what we meassure as two-way speed of light is then correct also for one-way. So, how to do that. Take two very precise atomic clock. Put one on the satelite in geostationary orbit and another one on the earth. We are not interested to measure exact time so any time dilation will not effect anything. We just need high precision clock to measure an interval of exactly one second. Now, equip satelite with the laser pointing to the Earth and that laser fires a beam with interval of exactly one second. Put some kind of detector on Earth that will detect this laser beam. Measure the time between each pulse. It should also be one second. OK, there is a time dilation because of the nearer proximity to Earth gravitational pool so it might not be exactly one second. But that is also fine, the interval between each pulse should be the same. We don't care of exact number. We just measure if they all are the same or not. And now, Earth will made a full circle during one day and since sender and receiver are stationary relative to each other (same reference system) we will have one-way direction also changed in respect of some absolute direction in space during day. So, if light does not have same speed in each direction and since direction is not stationary but is moving all the time, we should measure differences in time beetween received signals. When moving from higher speed direction to lower speed direction we should notice that time between pulses are somewhat larger then average and when moving in another direction, from slower to quicker direction, time between pulses will be somewhat lower that average. With that method we could preciselly determine also which direction is the most quicker and also most slower (oposite one). If there is no difference in time between each pulse, then that should be the prove that light speed is the same in every direction.

  • There in no poll

  • Is it possible to differentiate the velocity of light from one way to another if you set up an experiment where shooting the light from a machine that has its own timer hits a sensor, which then brings back a physical object at a constant speed to hit the original timing machine? That way you have a one way measurement of light since you can just subtract the time it took for the second object to arrive back.

  • What's happening with your brain cells when you put the bluetooth(microwave)earpods In your fat melon head

  • Does this glitch still work or did it get patched yet?

  • If it's infinite in scope, that means ALL possible combinations will happen an infinite number of times. IT WILL REPEAT, EVENTUALLY!!!!

  • Now, you sir... Just earned another follower

  • What if you entangled particles? The information of their spin can be transmitted instantly, so if two identical devices that could detect their spin were set up in such a way that one fires a laser as the other started a timer and stopped that timer when the laser was received you could determine the 1 way speed of light.
