No, one is not weightless in the stratosphere. While the gravitational force is slightly weaker in the stratosphere compared to the Earth's surface, it is not significant enough to make a person weightless. Weightlessness is typically experienced in outer space or during free-fall, where the effects of gravity are significantly reduced. In the stratosphere, the force of gravity is still strong enough to keep a person grounded. **

Flying in the stratosphere would be problematic for several reasons. The stratosphere is located at an altitude of 10-50 kilometers above the Earth's surface, and the air pressure is very low at this altitude, which would make it difficult for humans to breathe without proper pressurized cabins. Additionally, the stratosphere is also exposed to high levels of ultraviolet radiation from the sun, which could be harmful to both humans and aircraft materials. Furthermore, the extreme cold temperatures in the stratosphere would also pose challenges for aircraft and their systems. Overall, flying in the stratosphere would require advanced technology and careful consideration of these environmental factors. **

The decision to teach or study depends on your interests, skills, and long-term goals. If you have a passion for sharing knowledge, helping others learn, and making a positive impact on students' lives, then teaching may be a fulfilling career choice for you. On the other hand, if you have a strong desire to deepen your own understanding of a particular subject or field, pursuing further studies may be the best option. Consider your strengths, career aspirations, and personal values to make an informed decision about whether to teach or study. **
