I think I would notice that I lost gravity

i'm not sure if you've ever been in a plane, flying at 30K feet above earth's surface but if you did you can see the separation of earth to that outer stratosphere called space. there are several layers before you get there and the former concorde (of france) indeed flew on the edge of space & earth (that far above). now, you ask for visual difference? or are you asking for physical difference? the visual is as i stated. oh, you can see it very clearly but the physical is harder as by the time you reach that outerspace area and without the right equipment, you'd be dead. humans do live on more than bread & butter - like air!

The change from atmospheric travel to space travel is, as pointed out, a gradual one, and the various international aeronautical institutions have agreed to set the lower limit of space at 100 km (roughly 62 miles) above sea level. For the purposes of unprotected humans space is about 40,000 feet because there is simply insufficient air pressure above that for humans to exist. For spacecraft to successfully orbit for at least several orbits an altitude of about 100 miles (162 km, about) is required. If you notice, then, there are various types of 'space' that have to be specified. If there were an elevator, and you were on it and protected from the outside temperature and air pressure variations, as you went up there would be no specific point anywhere that you (without instruments, of course) could say 'stop...space starts here.'

Kind of. The sky would get suddenly very clear once you passed the troposphere. However, you aren't quite into outerspace for many miles yet. Feeling the loss of gravitation would depend on your motion, and the vehicle accelerating you into space.

Hi. The change is gradual and there is no place where the atmosphere just 'stops'. As you left the air would get thinner and it would be harder to breath. This is just what happens at the top of mountains like Everest. 100 km high is considered to be that start of space though.

yes no gravity
