If you got trapped inside an upside down dimension, where everything's upside down, would gravity still be a

There is NOT such a thing as a upside down dimension because then every science law must be reversed and thus instead of going into the future we will be going forward into the past or backwards into the future. The gravity instead of puling will be pushing away but as we are going into the past we would be EXACTLY NORMAL (so gravity isn't a factor) but as time went back you would die before you were even born which is weird.

0 * -1 = 0 so I bet it doesn't mean anything

What exactly do u mean by upside down dimension? Because im not clear about what the laws of physics would be like in this upside down dimension of yours....of course assuming that every thing as it is as of now would be upside down, gravity would definitely be in operation, bcoz wrt a certain frame of reference ur dimension wouldnt be upside down at all. 'upside down' is a relative term

If everything is upside down you are saying there is an up and a down...without gravity how would you define that? So although the question is a bit flawed...gravity would just be negative (ie reversed like everything else)

Well, I was just in that dimension. I wasn't trapped in it of course, which is why I am able to answer your question.

Interestingly, since everything was upside down, everything seemed the right way up!

If everything were upside down, there would really be no difference. Our up would be their down, and there up would be our down.

Yes gravity would very much exist, because we in fact need gravity to define up or down.

You dont need to go to another dimension to experience this. Say I am in US and you are somewhere in China. We both say that down is towards the earth's center, but if we about direction, with refrence to, say, the sun, then my down becomes your up (directionwise), and vice versa.

no.. gravity is caused by mass, as such since every thing is upside down the centre of gravity wld be still at the same location.anw there is no upside down sceneario, ur perception of up and down is determin by gravity.

if u r in space u can rotate 360 degree and there is no diff between up and down

I another dimension I couldn't begin to imagine what laws of physics would be in operation. There might not be any gravity as we know it.

yes, it will be the reciprocal. Gravity will become inversed... this is the best way i can explain it... sorry.

yes, but in reverse
