had there been no air in the universe, how the aircrafts would have flown ?

Answer 1

dude no idea ......:P

Answer 2

On The Theories Other Than The Displacement Of Air, Like Floating On Smilier & Dis smilier Pole Magnetics ( Long Gap Magnetic Leviation Technique Or Increasing The Gap Of Maglev's Tracks & Vehicles ), Or By Creating Equidistant Huge Magnetic Poles On The Surface Of Hole Earth Like Motor's Stator Pole & Treating Aircrafts As The Motor's Rotors, Floating On Poles To Poles By Syncronizing & Pole Conversion Techniques

Answer 3

As people keep saying, if there had been no air in the universe it is more likely than not no aircrafts would of flown, eliminating the question of how, (as someone rightly pointed out if a species manage to advance to the stage of aircraft dvelopment and live in an universe without 'air' (I am saying gaseous substances.) of course they might create spacecraft made today. True if lift could be created in substance like water crafts could be created but not 'air'crafts in the sense that word refers to crafts of the air same as spacecrafts refer to crafts of space.

Answer 4

Air on Earth is a mixture of oxygen, nitrogen, carbon dioxide and other minor gases. That is the air we know and breathe; in Venus, the "air" is made of mostly carbon dioxide.
Aircrafts do not fly because of air; they fly because of their construction, design and engines. It is the engines which provide the energy necessary to fly an aircraft. Air creates friction with a flying object; so aircrafts need more energy to fly than would be required if there was no air.

Answer 5

No Air exist in the universe. It's a vacuum.
If you meant the earth, yes, it has the air.
If you meant the airplane (boeing, Airbus etc), jet engines consumes Oxygen from the Air and provides back-thrust based on the 3rd law of Newton. This type of Aircraft cant fly in the space, as there is no Oxygen.
Yes, spacecraft (space shuttle) can fly in the universe (vacuum), as it doesnt need the thrust after the escape valocity is given. Escape valocity is a thrust provided to the spacecraft to quit out of the earth's gravity and once entered in the vacuum, it does not need any force to move. It goes on and on. Yes, the altitude can be adjusted by firing thruster rockets installed on the outer surface of the space craft.

So, Airplanes and Space crafts needs oxygen while flying within earth's gravity to fly (anti-gravity). Space crafts doesnt need it after it escapes the earth's gravity.

Answer 6

air ?
what dose air mean space do you mean space dont you
ok i tell you there is nothing as such Space in reality in nature
(but can be created artificially) but there is some thing wich fills it (long ago people called EAT-HER or eather) but that is not very same as i think but surly there is some thing wich cant be felt with sences ordinaly but can be examined (by making things throw in so called "space")

ok and if you realy meant air then...
not there is no air (air is defined as a subtance free to posses any shape in which it is contained and have nitrogen and oxygen in it) but there is the gravity and its functions wchich make things float

i said ther is not air in universe (unless where it is i mean like near planets and stars) because air is made by a complexive chain reactions of repultion and attrections after several deaths of a star

Answer 7

Well, that'd be a moot question. No one would be around to not breathe the not-air and thus invent "aircraft." You have to have an atmosphere to have "air" of any mixture.

Answer 8

best possibility would be to use rocket technology which uses the Newton's 3rd Law,air in the atmosphere would not be a necessity in this case,,,,,,,,,,,,,,,,,but if there is no gaseous state of matter at all(universe),well human civilization has not come across such a condition,when it does come scientists ,i believe, would definitely find an alternative technology

Answer 9

If there were no air, there would be no aircraft.

There would be "vacuum craft" built by creatures who breathe vacuum in order to live.

Answer 10

you cant type right or speak right, but air is a mixture of elements, like nitrogen, oxygen, etc. it is a possiblity that the elements are common in the universe, if they are then it is possible aliens are flying through "air", but you don't need to fly through our air, you can fly through anything as long as you create lift. a submarine creates lift in the water.

Answer 11

whats the use of an airplane in a universe without air where no life can exist.
