- Homework Statement
- Lisa travels to a dwarf planet. During the travel, she maintains the velocity v = 0.7c.

Kalle, who is observing from Earth, sees the travel take 43 minutes. How long does the travel take according to Lisa?

- Relevant Equations
- $$\Delta T = \gamma \Delta T_0$$

$$\gamma = \frac{1}{\sqrt{1 - v^2/c^2}}$$

This was a practice question, so it had the answer with it, which is 31 minutes. However, I'm confused as to why Lisa experiences T

My LaTeX code wasn't working in preview btw, so idk if it will work when I post.

_{0}. It isn't exactly an event happening in Lisa's rocket, but rather her just moving through space. From her perspective, it should look like Earth is moving at the same speed in the opposite direction, right? So why do they experience different times and how do you know which one is T_{0}?My LaTeX code wasn't working in preview btw, so idk if it will work when I post.
