  • It's AumSum Time.

  • What if there was no Gravity on Earth?

  • No Problemo.

  • I will order my burger from space.

  • Oh AumSum.

  • From purely physics point of view.

  • There would be no earth left, as no gravity means no mass.

  • But, leaving this point aside, let's see what else will happen.

  • Oceans, rivers and lakes will float away.

  • Entire atmosphere will vanish, only vacuum will be left.

  • Everything on the surface of the earth including humans, cars, rocks, etc.

  • Will become weightless and float away into space.

  • Things which are rooted into earth like trees, bridges.

  • And buildings will remain, but not for long.

  • On a funnier note, anybody will be able to lift heavy weights.

  • Football will become a one kick game.

  • And there will be no need of stairs or elevators.

  • Finally, earth will also start breaking into chunks as it is held together by gravity.

  • What if all insects disappeared?

  • No worries.

  • I have their photographs.

  • You might think insects are inconsequential, but the reality is.

  • Without them, there probably would be no life on earth.

  • The first life to get affected, would be plant life.

  • Most plants in the world are angiosperms, that is, flowering plants.

  • Without insects pollinating them, plant life would gradually disappear.

  • Gradually, birds and mammals feeding on plants would also disappear.

  • Further, insects are food for many birds, frogs, reptiles, etc.

  • Without insects, they would also start dying.

  • Then, animals eating those animals would also start dying.

  • This would ultimately lead to a domino effect.

  • Finally wiping out the top of the food chain, that is, human beings.

  • Also, don't be surprised, if you suddenly see a lot of dead things everywhere.

  • This is because insects are decomposers.

  • Without insects, decomposition process would take much longer.

  • What if wheels were never invented?

  • No problem.

  • I'll just use my Private Rocket.

  • Oh AumSum.

  • Wheels are believed to have been invented almost 5500 years ago.

  • Ever imagined what the world would be like without wheels?

  • How would you go to school, work or even on a holiday?

  • Bicycles, cars, steam engines and even planes, nothing would be possible without the wheels.

  • Yes, horses and sledges would be there.

  • But it would be a super slow and super rough ride.

  • Not only in transportation, but wheels are also a major component of the industrial revolution.

  • Elevators, blinds, cranes etc., all have some form of wheel hidden in them.

  • Now, on adding teeth to wheels, gears were invented.

  • Clocks, grinders, car engines, bicycles and other complex machines work with the help of gears.

  • So, basically, if wheels were never invented, we might still be living the pre-historic way.

  • What if earth lost oxygen for 5 seconds?

  • We would need to organize a search party.

  • No.

  • If it was just 5 seconds.

  • We wouldn't notice changes in our breathing.

  • But do you know what would happen around us?

  • Earth's crust contains 45% oxygen.

  • Without oxygen, crust would crumble.

  • Causing the ground to crumble and we would be in freefall.

  • Buildings, bridges and concrete structures would crumble into dust.

  • As oxygen is the binding agent for concrete.

  • Cars would stop.

  • And planes would fall from sky as their combustion engines wouldn't work without oxygen.

  • Also, losing oxygen means losing almost 21% air pressure.

  • This would cause our inner ear to explode, causing hearing loss.

  • It would also become darker suddenly.

  • Why?

  • For sunlight to reach us, it needs to bounce off air particles like oxygen, dust etc.

  • No oxygen means much fewer particles to bounce off, thus much darker.

It's AumSum Time.
