Mine was from Werner Israel who's mentioned in the Big Black Book but not one of the big names on the front. I imagine Kip's course was fun!

Have that on my list of things...but it's a very long list lol

Normal free fall. You won't see the heat death.

You will still see it blue shifted and sped up..and get cooked by the radiation. Not a good end lol

Proper time is what you measure on your (Apple) watch.
Assumed its Apple because you're a posh boy ❤️🐰🐰

on the outside. The red area and one of the green lines meet at the top, So while there is extreme time dialation, you do not see the entire universe flash by in a fraction of a second. (Different if you fall into a spinning or charged black hole!)

everything that travels at or slower than the speed of light. At the very top of the diagram is basically the end of the universe or the infinite future. The thick black line on the upper left is the event horizon. The red area is the hovering observer. The green line represents a light flashing

Gotta do this on my phone so forgive the typos if any...locked out of everything else 😭. The attached diagram is called a Penrose diagram. It's a way of condencing all of space and time down to a finite area. 45 degree lines represent light rays. The hour glass shapes represent the paths of

You'll hit the singularity way before. All in your proper time

Give me a bit on this one,I'll draw a spacetime diagram. There of course will be extreme time dilation relative to the outside far off regions but the question is will you see infinite blue shift. Technically you'll see the end of the universe but not in a short time

Also hold those creative impulses in your back pocket. If you're interest in physics hasn't been killed by your teacher, Ill show you thr good stuff!

3/4 is good enough for survival. Gets you through it. The sources of error disallowed are the ones I'd use and I'm a working physicist. Would love to hear the actual answer. (Also the sources I got another kid through high school with)

Anytime! Benefits of having a physicist friend. ❤️🐰🐰 One of my presents this year was a shirt with this equation on it (Einsten equations for gravity)

ð²x/ðt²=c. Know calculus and derive the rest!
The gravitational force equation they'll show you is the weak limit. The full equations are vastly more fierce. (In 4 dimensions nonlinear)

So litteraly every souce of actual error. Blow the teacher's mind and say you have to account for gravitational time dilation between the bottom and the top of the the stopwatch.
Yes we do have clocks capable of measuring that. Improvement. Lay the clock flat
