I agree with Spocom, I studied quantum mechanics a couple years ago, and based on what I learned, I`d rather not think of it `correctly`.

The distance between two events in spacetime is sqrt(x^2 + y^2 + z^2 - ct^2). It`s simple Pythagorean geometry (except for that pesky little -ct^2 term).

this quantum stuff needs further study and this clip don`t cut it . . .

This is only true if you think of distance as how difficult it is to get from one point to another, rather than a measurement of the space between those two points like most of us think of it. This is false in my opinion, because distance is not a measurement of difficulty.

I cannot force my brain to think about time and distance as being tied together, so this whole things comes across to me as being like one of those scams where in the midst of explaining a word problem a cat suddenly becomes a dog and you`ve just proven that I should give you all my money.

does this mean that tomorrow is actually yesterday?:-/

cajun - plank time = plank length

1 plank length per plank time is exactly 299800000 m/s, i.e. the speed of light.

Plank length and plank time is the resolution of the universe

well, his pretty drawings DOES make up for his total lack of understanding of relativity, amazing.

Glad you asked! It`s a variation of Pythagoras theorem, adding in a fourth dimension, time. Hermann Minkowski discovered that by taking the negative of time multiplied by the speed of light constant "c". So the revised equation is s2 = x2 + y2 + z2 - (ct)2.

Wow that was explained terribly. Premise is true though - faster you travel, space shrinks and distance becomes shorter.

Only if we can get the neutrinos to agree with SR.

True as that may be, the difference between traveling a mile at 3mph (walking) and traveling a mile at 70 mph (highway) can`t give you a feasibly measurable difference in relative time required to gain the mile from any given starting point. We`d have to get to thousands of miles per hour to gain even fractions of a second (think GPS satellites and their chronograph corrections). We, as normal humans, will never experience that.

Still a total mind-blower, especially if you are used to conventional 4D thinking. O_O

As a physics student i can assure you.. You heard correctly.. If you travel faster, distances become literally shorter, and time slows down around you.. it really is a complete minddrat.. I still don`t really understand it.. I just have to accept it since it`s been proven over and over again..

It`s not abstract. He`s just explaining it in a really confusing way. All things move through either time or space or a proportional mixture of the two. You can move entirely through time (like super fast forward) but then you won`t be moving through space. Or you can be moving through space really fast like a lightning bolt, but you won`t be traveling through time. Most things, are a mix of the two traveling through space and time in less extremes.

Regardless of what the content actually is... if you assume the majority of people will not understand it, as you seem to think here, why post it at all?

Like most people are saying, this video leaves out a lot of details. However, if I wanted to explain the general concept of relativity to someone with no science background this would be a very simple, easy to grasp option.

He`s quite incorrect.
His main premise was based on equating something that was "harder" to something that was further away.

Special relativity simply explains how time and space shrink and expand depending on how fast you are traveling. Granted there are plenty of mind-bending quirky details that can go along with this, but those are best left for the classroom.

Yeah, he kind of blew through the fact that, as you approach the speed of light, not only does time slow down (which is somewhat well known) but length also shrinks (which was the point of the video). It`s straight out of relativity, though a lesser-known part of it.

There is nothing "mind blowing" or surprising about this at all. He`s just stating a basic fact. It`s like if I made a video pointing out that most people, in America, wear shoes outside. I mean come on, is the fact that getting somewhere faster is harder than getting there slower, that hard a concept to grasp?

i`m kinda surprised there wasn`t an ad for Hyundai or another car manufacturer at the end

Too much visual stimulation.

The youtube comments made feel good about myself because I was not the only who didn`t get this.

So what is the distance from Bored to Entertained?
