Not encountering any edges

Straight line you say..

What’s these lines

Planes?

What if we throw the earth into the sun like a frisbee

what lines

Hm I don’t understand

You wouldn’t walk an actual ‘straight line’ around the earth.

You’d be doing a large circle.

Yeah

?

I mean that

mean what

if you are responding to whoever that is i have them blocked

I walk a line that curves very slowly but I will eventually turn 360 degrees

Around earth

yes

a straight line on a sphere is a thing

I’m responding to him u blocked

C

Whatever, since this chat is not moderated, I’m not going to bother.

its more general because in spherical space you can move in a straight line
its just called a geodesic

I’m in the USA, if I walk a perfect straight line for an enough amount of distance I’ll eventually get to USA again

The line I walk curves so little you can’t even notice it

Because of the size of earth and how long your traveling

because in more abstract spaces you need to define what a straight line is
all you do is define a metric in that space and from that you can derive a straight line called a geodesic

But I am gonna some point turn 60 degrees 90 and at some point 360 degrees

And USA lies in the 360 degrees

That I’ve just crossed

some would say that the metric defines the space

Planes can’t fly to space and go outside of earth cause of gravity not allowing that

Simple

You can’t escape earths gravity unless you travel equally or above 25000 mph

from its surface

escape velocity

The more a plane flies higher the less air molecules are gonna be there which will make it harder for the plane to stay airborne, less oxygen results less combustible fuel to power the engine

ye

also most planes are self stabalising

The highest distance a plane flied above the surface was 123532 feet high but yet made it 1/3 the way to space
