"True or not?"

Sun spins around earth, obvious: just look up.

At night time the sun drops/disappears and in the morning it rises/appears.

Its just common sense, I can't believe its taken people this long to figure it out.

I have a surprisingly distinct memory froma young kid of first being able to visualize how it made sense that a spinning earth going relatively slowly around the sun also explained the phenomenon we see every day above us. I feel sad that this guy didn't get to experience this fun little observation.

This is why I never fly.

Clearly the guy is correct. If he wasn't then we wouldn't be able to trampoline as the Earth's rotation would move it from underneath us while we were in the air. Earth is stationary.

So, say you go up in a helicopter. You hover over a spot in the earth. You feel like you are stationary ( you are, relative to the earth) , but you are actually rotating with the earth?
Surely if you "stop" relative to earth, you could just hover until your destination spins round underneath you? Or is it not possible to stop relative to earth?

where I am, the speed at the earths surface is about 600 mph. Surely if you jump in the air, hover, and then decelerate by 600 mph , you can look down and watch the earth rotate past you at 600 miles an hour?

I know this must be wrong, but why is it wrong? What am I missing out?

and your plan for all the air that is also moving 600mph? Moving 600mph through approximately stationary air is really hard

well, cant we just use that 600mph air to push us to our destination without having to use any fuel/energy? :P

Your mind is really going to be blown when you find out how fast our solar system is moving around the milky way...or the milky way relative to other galaxies

Conservation of angular momentum is fun for the whole family!

I should add that I meant to add a smiley to this post. Just in case there's any doubts...

Being stationary is an illusion. You are moving at the same speed that earth is rotating while you believe to be standing still and you still move with the same speed and same direction when you jump up.

I think what we should ask our self is, what makes it possible that someone while being totally wrong, thinks and argues as if he were absolutely right? And what can we do to avoid this happening to our self? And How can we be sure that lots of our assumptions are not just as wrong as his while we think they are absolutely reasonable?
Science explains lots of things but for example it doesn't prove right or wrong what we think about our neighbor about our self about what is good and what is bad, what is just, what is not just.... .

Dunning-Kruger effect.

I always find it interesting how very wrong human intuition can be.

The interesting thing is how easily this can be disproved. Throw an object straight up next time you're in a moving vehicle and see where it falls.

My interpretation of this effect has always been that because I think I'm bad at things I must actually be excellent.

We're all confident idiots

ye, so all I need to do is become stationary with respect to earth, and then save energy by just letting my destination rotate round to me, right?

It costs energy to slow down.

You're already stationary with respect to earth. Or at least I am. When I look down, the earth doesn't appear to be moving.

W0X0F's response is true but I know what you meant to say. To which my response is, in order to stay still, you'd have to constantly fight 600mph wind. You can view it whichever way you choose: either the air is still and you're moving 600mph through it, or you're still and braving 600mph winds (and using the same amount of energy doing so).

Edit: there's also the issue of getting a strong enough push to slow to a halt, so it wouldn't work even with no atmosphere. If you're driving 60mph and you throw a baseball backwards at what would be 10mph, it will be going 50mph forward. Same thing happens when you jump off the ground, you're like the ball being thrown from the car.

The only difference between acceleration and deceleration is frame of reference.

Intuition is very far from a guarantee of solid knowledge. This is why, for example, it is generally a very bad idea for most people to start mountain-climbing without any training from people who has knowledge (gained from someone's experimentation and/or more sound reasoning).

And now, we can mock this man all we want but you have plenty people on this board who has argued from almost purely intuitive perspectives on issues like perception, knowledge, will and even the existence of god herself. Not much better.

That isn't to say intuition is without value, it holds extreme value. It merely needs to be tempered.

Not only intuition is very far from a guarantee of solid knowledge. In respect to science (physical world) it might work but in other matters it seems not to be very promising. If it were there were no more philosophical discussions. If it were, we could just sit down and solve lots of social problems with reasonable logic.
What I found very funny is this guy's mimic. He looks at his audience as if he were talking about the easiest thing ever to understand. So one thing which affects logical thinking seems to be lack of knowledge. What else affects it negatively?

Not from my point of view.

Tilted me.
