What wouldn't we be able to do if we didn't know about Gravity........

[urbantechie]

.....?
I know one thing is Space Travel.

 

[Regine]

oops
misunderstood the question

 

[Killbat]

I wouldn't be able to trip and fall and get hurt. Then I wouldn't be able to swim.

 

[urbantechie]

No, if we didn't know gravity exsited. How it works.

Like if we didn't know how gravity worked, then you wouldn't know that a space ship going real fast can go into oribit.

 

[Killbat]

*PST!* We don't know how it works.

 

[Regine]

I think the question "What we wouldn't be able to to if gravity didn't exist" would be interesting too.

 

[urbantechie]

Cmon!!! I need one more idea like mine and that would end a 3slide presentation!

 

[IamDavid]

If we didn't understand the effect of gravity we wouldn't know how to build Skyscrapers?

 

[urbantechie]

Sky scrapers? Didn't they have huge castles before Sir Issac Newton thought of Gravity?

 

[Weyoun]

u can kiss planes goodbye, and basically anything that needs to be simulated in an entirely mathematical environment....

 

[Capn]

No planes, no long range weapons, there's lots of stuff. We couldn't possibly be here today in this modern world with out our current understanding of gravity.

 

[urbantechie]

K, good info here .

Weyoun: How would I explain?

 

[Pretender]

If we didn't know the exact way that gravity worked, we wouldn't know for sure that a 1 ton boulder and an apple fall at the same speed (not counting any air resistance, of cource), although we could probably test that.

 

[Pretender]

Certain things, like lift or drag don't really require exact mathematical details of gravity to be known. But calculating more precision scientific things that require knowledge of the exact speed of acceleration due to gravity, etc would be difficult, if not impossible.

 

[urbantechie]

Anything more specific? What about the logn range missles? How to explain or put it in one sentence?

 

[Regine]

They had castles before they knew about gravity. But these were big structures. Within cities "medieval skyscrapers" did not exceed 3 or 4 stories in height. Then again they built huge cathedrals. How they managed that without knowledge of how gravity works is beyond me.

 

[Weyoun]

toolgirl's right, castles are of a different design to skyscrapers, a compratively small base area will all that mass on top of it, it *needs* mathematical calculations to build foundations etc, whereas castles are effectively big piles of stones.... i also wouldnt want the top of my building falling off, and in general, the whole design requires great mathematical precision, and im sure gravity'd be in there somewhere

 

[urbantechie]

How would I explain the Mathmatical Enviroment one? That one will make me sound smart!!

 

[Weyoun]

for a purely simulated environment with true to life physics (basically a world in a chip), it would require an extensive knowledge of everything that happens in the world, including to a per-atom level, although that is surpassable to a degree. my goal (ok secondary or tertiary, but a goal nonetheless ) is to create a true simulated environment, which under the right seed, can actually predict time. i know, a long shot if not impossible, but heck it's worth trying time to get a phd chem, physics, comp eng, damn gotta finish high school first

 

[urbantechie]

<< damn gotta finish high school first >>



rrrriiiggghhhhtttt


I finally got it done. Thanks for the help guys!

 

[Weyoun]

man, im 16, and one mighty fuc|<ed up cracker atm, im seriously depressed, so dont go pushin your luck

 

[urbantechie]

Ok. I'm pretty wierd my self. 15yrs old, a computer tech. Almost Professional Photographer, electronics freak, want to loose my virginity and I have a life!!! (Thank god!)

 

[Weyoun]

<< and I have a life!!! (Thank god!) >>


now *that's* BS

anyways, im good at maths (ok, for aus standards ) kick ass at japanese, and suck at life. i hate myself and everything i've become. and *yes*, it's my fault

 

[BoberFett]

If we didn't know about gravity then we could all fly.

 

[sandorski]

If we didn't know about gravity it would be more difficult, but we could still have most of what we have today. The downside to not knowing would be trying to get people to Trial and Error our way into our tech. Many attempts would have to be made, for instance, to simply leave Earth's atmosphere. The first few attempts would start with say a basic rocket which raised 10ft then crashed. Next the rocket is made bigger and 50ft is acheived. Next the rocket is made huge and it just takes off and gets lost. Eventually the best sized rocket is found. After time mathematic formulas can accurately predict rocket behaviour without knowledge of gravity, probably using some kind of equational moderator like PI. The numerical quantity of this moderator would probably end up to be exactly equal to what we know to be gravity.
