Frankie and Benjy Mouse Päivä sitten
@Sky watch👁👁 All the stars in our neighbourhood are moving in about the same speed and same direction. Their position changes just very little in 100 years. except a few. Parrallax is the thing that you see when a mountain far away in the distance seems to not move while you are in a car at 80 miles/hour. It looks like it doesn't move and we know it doesn't move but after one hour it has changed position from your point of view. Same goes for the stars but they move a bit. On the scale of the universe 1 lightyear is nothing.

It’s common sense down and up are perspective driven like right and left The earth is plays with the North Pole on top so we create a perspective where North American is on top and South America in down at the bottom Most of life is a perspective Driven reality Wanna know what left right up or down is Look at something and stare at it anything under it is down anything above is up and you move your eyes up then your first position is down if you move your eyes down your first position is up. Like is all perspective and that’s why we are selfish humans and live in our false realities

If this is true, would a vertical steel beam fall faster than a horisontal one? It has a greater difference between the time from the top to the bottom of its beam than a horisontal beam has.

I disagree with time being the fourth dimension, it just can't be... It exists in all dimensional spaces for the starter... and here's the main thing.... Let's say there are 4 dimensional creatures, capable of visualizing everything in 3 Dimensions.... which means they will not see only height and length like us... they'll also see the width of an object; To sum it up, they'll be capable of seeing through 3 D things.... now let's create a 4 dimensional graph of that creature's motion, the dimensions are independent of each other... hence let's assume a curve on that graph, which started from t=0 and also ended on t=0... now do you realize the problem?.. His other 3 dimensions' coordinates are different from it's initial coordinates. If time is the 4th dimension, then it's just impossible for a being to have 2 different positions at the same time. But why stop here, let his graph be sinusoidal and let it go on and on, now the creature has multiple positions at any given time...His displacement in Time dimension is zero but he was constantly moving in Time dimension also (to and fro), which means he was frequently going back in time... Right? ... He went back in time but *not* *to* *the* *same* *place* . That's just absurd. EDIT: Why I took a 4 Dimensional being?? .... Because only a 4 dimensional (or higher) being is capable of moving in 4 dimensions. Also I explained their vision to create a clearer picture. I assume all are known to the fact, that, we see our surroundings in 2 dimensions (The lights and shadows gives an illusion of a 3D vision )

What you are talking about is a fourth spacial dimension, he is talking about a 4th temporal direction. You could have creatures with 4 spacial dimensions and then have them have a 5 dimension of time

Our planet is fixed to the sun. Our sun is fixed to the center of our Milky Way galaxy. Down is relative to our fixed position. Down is only measured with gravity so down can only be our planets south which is relative to the top and bottom of the Milky Way. But there is no way of knowing which is the top or bottom of our galaxy so down should actually be called IN.
Conner Scoggins
Conner Scoggins 8 päivää sitten
Down is where the object or being’s center of gravity is pulled directly into the center of gravity of another object. But when you consider everything has a mass and gravitational field it gets messy. But when two things are acting upon the object like the earth, sun and a human the mass of the objects makes a list. The sun pulls the earth with us on it, but the earth is also closer to us so it’s gravity acts upon us so we are attracted to the center of mass of the earth instead of the sun because of distance. The opposite works with “up” which would be the zenith directly above an object/observer and opposite of gravity.

18 seconds in and this is going to crazy... 41 seconds in this guy doesn’t know what gravity is... WOW 2:25 this guy knows what gravity is but so far his calculations are... please don’t write a hate comment after this I guess you could say The theory up the wall... 3:33 oh I’m so sorry I didn’t know what HEAVY IS. 3:44 Sooooooo... mass isn’t weight? Please continue then. 4:37 this guy straight up stupid! What in the world! Or should I say straight down stupid... please don’t still write a hate comment. 4:49 but that’s video game! 4:59 three days! Why! So this theory it’s not really you teaching us it’s the Game teaching us... lazy. 5:27 finally the good stuff! 5:57 but you do know you have your hands on that right... I now see how crazy you are... and I now see the reason why you have a beard. ACT: Face slaps. 6:41 is this a excuse to not call yourself fat you’re fat and is doesn’t count you’re dumb this level already paid for that. 7:19 you know I’m 10 years old and in fifth grade right? The beginning of the year. Everyone excuse me to see what date this was and I’m not talking about the KiSs type i’m talking about months years even days if that happened.7:38 2017... not 2021 i’m sure you regret this video by now. 8:10 so your Vsauce? I thought you were just some crazy guy with...crazy. 8:33 do you know what the extra minutes are just something to waste your time. Remember good theory but I’m am the blockhead see you out!

"Gravity," as we experience it, is nothing more than the drag coefficient of time traveling matter. Everything works towards balance. Temporal inertia? An object (which on a macroscopic scale is a collection of many smaller objects) can never be "at rest" in time. (Outside of a black hole, at least) We are always "moving" through time. So you drop the pencil and what happens? The top is moving faster through time, the bottom is moving slower through time, the earth is moving slower still through time. So it "falls" from an area of higher time density to lower time density. Gravity is temporal buoyancy? I got lost somewhere in my train of thought, because now I can't think of a suitable analogy for mass relative to my new analogy for time. I'm going to look at this when I wake up and see if i can make sense of it, or if it's just lack of sleep nonsense

Down can mean a few things. Downward would be the direction that gravity pulls you. Downtown would be down town if you was above a town on a map, uptown would be if you was south on the map to a town. Down is the opposite of up, incase you didn't know that one either. I'm down with this(bending my knees with a flick of my arm) down is south, up is north. What's up, he said at someone who got excited. What's getting you down, he said to the girl who was sad. Down is low, up is high. Does that explain it.
