What's the opposite of a cat?

See the whole pencil thing

 

^^^

there can be no deffinitive opposite of a cat, as to have an "opposite" you must deal with finites.

in this instance NOT a cat would be the logical answer, however flawed.

 

Opposites (true) deal with Finites. matematics or geometry.

`A `maybe said to be the Opposite of `B` or Geometricaly Opposed.

 

for a Cat ANY cat (and therein lies the problem) the Opposite may not be correctly applied

Q. since gravity is derived from space being curved,would it have an oppisite were space had a distribution of matter with no intrinsic mass. can there be a anti gravity? cause the only apparent thong with no oppisite is gravity...............

you present an iteresting idea when talking about a specific color, phase cancelation with addative or subtractive synthesis of color would be interesting from a semantic point of veiw, it could be argued that it would be the opposite of Green, infact it would be a conflicting waveforn, peak to trough in anti-phase. the true opposite it black though, you`de be simply providing a means to obtain black

wot?

hmmm.... maybe the opposite of gravity could be a force that pushes you away from matter and not towards it. Maybe it could have an opposite effect?

There is an antigravity, that is derived from the interaction of antimass (NOT ANTIMATTER, that's a positive mass with a reversed charge, but antimass; negative energy) with normal mass.

oh ok. So there we have it!

It doesn't mean there's an antieverything else though.

 

And -ve mass is only speculatory at best, although so was antimatter once.

oh ok. So case closed! Thanx alot for fixing everything up!

LOL, that`s either inspired more questions, or the fear about ever asking anything again

no. not really but, i get the general idea ! And yes, there are about a billion other questions !

seriously tho, post away dude

ok. MrL_JaKiri said antimass and NOT antimatter. What is the difference between mass and matter. Doesn't matter make up mass?

mass is a bit like weight, matter has volume.

for most instances when talking in terms of that contain gravity in the positive mass can sometimes be replaced with the term weight. in zero G however a body is said to have MASS but no weight

oh ok. And we would call gravity associated with anti-mass, antigravity? Would that have a different effect to what we feel here? Other than the strength of course.

anti mass I know little about, anti grav as far as I`m aware doesn`t exist outside of sci-fi films and comic books.

Except that if you have antimass you have to have antigravity...?

Matter is the 'stuff' in question. Mass is a quantity of the stuff.

 

It's like saying that people are made of tall to say that mass = matter.

oh ok. Thanx guys for all of ur help

At it's very simplest,

 

F = GmM/d^2.

 

For real distances, d^2 will be positive, and G IS positive, so obviously you'll get negative values if m and M have a different sign.

surely if M or m have a different sign. M and m would just give you a positive again. aah, reminds me of Dirac.

Positive times negative equals negative duder.

 

Your brain isn't on today.

 

P*P=P

 

P*N = N

 

N*N = P

Anti-Grav and Anti-Mass are synonamous. Anti-mass experiments have been performed by creating an intense magnetic field around an object freeing it of the effects of gravity (this was done terrestrialy). Though I really don't believe "anti" is the proper term for the absence of, but should instead be reserved for things that come into conflict or stand in opposition.

That's not what I'm talking about at all, and as far as I've heard that's quackery from russia.

exactly duder, which is why only one of M and m can be positive, zou said:

the and should be an or I reckon

 

btw I reckon the duder meme is the new sup.
