is there a 5th 6th or 7th dimention time is the 4th one?

"Time" is not a dimension in the same sense that x,y,z,a,b,c, ..etc are spatial dimensions.\n\nThough the human mind is cabable of imagining muti-dimensional space, and can create clever matematical concepts supporting the idea, there is not one whit of physical evidence to support it.  And there is ample evidence to refute it.  \n\nTake gravity, for example.  Measurments show that gravity decreases as the inverse square of the distance from the source, exactly as it should in three-dimensional space.  If there were more than three spatial dimensions, that wouldn't be the case.  So if you want to postulate there are more than three dimensions, you've got to explain why gravity ignores them!\n\nAlso, take ElectroMagnetic Radiation (EMR), which also behaves the same way - i.e. it decreases as the inverse square of the distance from the source, just as it should in three dimensional space.  So if you postulate more than three dimensions, you've got to explain why EMR doesn't know about it!\n\nAs to string theory, scientists proposing it can't agree whether it requires twenty-six dimensions in order for the math to come out right, or "just" ten!  And they all admit there's no known way to prove or disprove the theory itself. That's makes the theory pretty weak. In fact, it makes it almost science fiction! Great mind exercise, but no eidence of reality!\n\nEinstein's theories provide predictions that can be proved or disproved. That's one reason they are so powerful.\n\nSo the jury's still out on multi-dimensional space - and pobably will be for some time to come.\n\nBut it's fun to speculate!  Just don't bet your food money on it!

We live in a 3 demensional world, which means you can jump / move up and down (one demension), right and left (one demension) and forward and backwards (one demension)...which totals three. The fourth demension is considered to be time, because you can 'move' in time as well...which means you can not 'move' in space from Point A to Point B without spending 'time' doing that. In other words, you can not move in space without moving in time as well (It took me 9 seconds to move from my chair to the refrigerator and back)...therefore, time is the fourth demension.

Hmm, I hope the reason is not because 4 is IV and 6 is VI in roman numerals. If so, I can't finish the proof by explaining why someone would perceive IV and VI as the same number :)

I would say the number 6, but the 9 is then backwards.  Works though.

well we know the 3 space must be even, in order to avoid the last space resulting in another 5\n\nhmmm... i'l work on it, provided you're working as well!\n\n..and #3 mustn't be 0, to avoid another 0\n..lol i'd have had it if i had been home...i made a program to do it, and then left before i finished/ran it lol\n\nbut that, is of course, the correct asnwer, 396*45=17820\n\nhaha thanx for the challenge!

I think that the 4th is the final. But if there is 5, i gonna get it!!

4D is the fourth dimension. Some people think that is time, but those people are idiots. A line is one dimensional, a sheet of paper is two-dimensional, a cube, or anything with volume is three-dimensional. As you can see, a sheet of paper has a right angle in its corner, which if you place the line at the top, the sides are orthogonal(a fancy word for a right angle or perpendicular) to the line. A ream of paper(100 sheets) has a height that is orthogonal to both the top & sides of the paper. The fourth dimension is the next step in this progression, and is orthogonal to all of the previous dimensions. It continues like this, with each dimension being orthoganal to the previous n-1 dimensions.\n\nIt is not possible for most people to visualise 4D, as it exists outside of the realms of our perceptions. I had a math professor who knew someone who claimed to visualize 4D in his mind, but that's as far as it is possible to visualize. It is possible to work with numbers in 6D when talking about vector calculus.

it's 1 X 2 X 3 X 4 X 5 X 6 X 7 = 5040\n\nEDIT: Guess I was a bit slow here. Anyway, if you open your windows calculator. Click 'view' and pick 'scientific' you will see a much more complicated calculator.\n\nAmongst all the buttons is on that says N! (4th button for left on next to last row). That is the factorial button. Just hit '7' then the N! button for your answer.

Mathematically n dimensions can be described but our experience is only 3 dimensions So the properties of fourth dimensonal shapes can be mathematically described and a fourth dimensional quantity that is in units^4 can also be calculated\n\nThis is an argument that the 4th dimension is time. That cannot be the case when one considers the properties in 3d are L, L, and L One would immediately envisage that the 4th, 5th .... nth dimensions would also all be L\n\nA tesseract, the 4 dimensional equivalent to the 2 dimensional square and 3 dimensional cube, is not a time related object at all. Its 3D projection can be build and the objects equivalent of a 2D shadow seen easily. In 4-space it occupies L^4 units^4. Wikepedia has some interesting information and projections of a tesseract

Scientist belive there are several dimesions.  Remember dimensions are based on measurement.  Length width height, 3 dimesions so we are in the third dimension.  A showdow for example only has length and width so it is the 2nd dimseion.  We cannot comprehend other demensions because we live in a 3d world where only LWH exist.  It is like asking your shadow what is tall, he would know because he lives in the 2nd demsiond.  So there are other dimensions yes and we can dicipher them though the wonders of mathmatics and physics.\n\nGravity works likes a bowling ball on a bed.  Think of the bed as the fabric of space.  If you put a tennis ball on the bed it would "gravitate" towards the bowling ball.  This is the theory of realtivity.  A worm hole forms when a really heavy mass punches through that space fabric.  If you had a million pound bowling ball it would go right though the bed.  The same things happens in space that heavy mass punches right though to the other side forming a worm hole.

Heartsense is right.  I'm chiming in to say if you mean the product of 5/6 * 6/7 * 7/8 * 8/9 * ..., then that product tends to 0 since the denominator of the nth term cancels out with the numerator of the (n+1)st term, so as n approaches infinity, you get 5 over infinity (not really "over infinity" but you know what I mean) = 0.

omg your kidding me... thats a trick question. the set would already  be over if it is 6-4.

The actual question you should be asking is.  What is seven times six?  Answer:  42
