I found out that Death Valley reglarly reaches temperatures in the 120s in summer...how can anyone survive in such hot weather? I read that there's a park you can go to, but is this park at the hottest/lowest point in the desert? It seems ridiculous to me that anyone could stay alive in such an extreme climate...

There are two stars A and B in two remote galaxies.
We measured angle S between these stars in
the sky, and asked their hypothetical inghabitants
to do the same, ie angles between A&S from B,
and B&S from A. Is the sum of angles
A + B + S greater, equal to, or smaller than π?

it will take 42 minutes to travel to the other side,
if the conveyance is allowed to free fall.

This energy-effective method of transportation
has the disadvantage that passengers will remain
in weightlessness for prolonged period of time,
and may feel uncomfortable.

If we want the passengers to feel normal weight
during the travel, and minimize travel time,

how much time will the trip take in that case?

Our teacher gave up on us already,
all he wants is a just number.

How big was the universe (and in how many dimensions) before the big bang?
If I dug a hole in the earth and drove into it at the speed of light, would my headlights shine all the way through?
Could I have traveled back in time to fake the moon landings?
If the earth stopped spinning because of a black hole, would we notice (since my cousin's trashman said there's no such thing as centrifugal force), and would that turn off gravity and change the color of the sky?

I used to think that our DNA was one long strand but then I realised that our chromosomes are seperate from each other therefore DNA could not be in one long strand. Can it?

Does each chromosome have one long strand or are there more?

-6-3u+9-(-4u)
would you leave the -(-4u) as it is and combine the -4u with the -3u, or would you make the -(-4u) a positive 4u and then add it with the -3u?

I want to learn every peice of info about the atom. From its protons to its structure to its energy and how it played a part in the atomic bomb. I just find it so fasinating how such small things can release such energy and how they are mostly empty space.

P.S. do you know any careers that might study this stuff? I am in high school and I want to have a career that deals with this stuff.
