Answers
1
Why do you use light projectiles in superheavy element manufacturing?
Heavy elements have more kinetic energy so the nuclei breaks
Requires less energy to accelerate in particle accelerators
Both B and C (i.e. diamond and square.)
chances of nuclei forming are smaller with heavy nuclei
2
How can you make the warp drive use less energy.
rapidly oscillate the warp bubble to soften spacetime fabric
make the warp bubble smaller and thinner
make the vessel go slower
all of the above
3
What are neutron stars?
another name for magnetars.
Ultra dense cores of massive stars made out of neutronium.
Stars that have neutrons in them.
4
Why is U-235 fissile?
because of its high atomic weight
Just because...
because it was destined to be made into an atom bomb.
The energy of the neutron is enough to split the nucleus.
5
Why are Technetium and Promethium radioactive?
Because there is a lot of repulsion in the nucleus.
Because 43 and 61 are unlucky numbers.
Stable isotopes are ruled out by neighboring elements.
The strong force glitches for those atomic numbers.
6
Why is CO2 a linear molecule?
because the oxygen atoms hate each other.
IDK
the p orbitals of carbon are linear.
because the sp hybrid orbitals are linear.
7
How many classes of elementary particles are there. What are the classes?
3, proton, neutron, electron
3, quarks, leptons, bosons
4, quarks, leptons, photons, elements
2, protons and electrons
8
Why are heavier elements less stable than lighter elements?
because they choose to be unstable
the strong force collapses heavy nuclei into a singularity
There is a lot of strain on the orbitals
There is a lot of electromagnetic repulsion in heavy nuclei
9
Are U ready for hard questions?
No, hard questions make my brain hurt
Yes, Bring it on!
10
What element has the highest magnetic moment?
Nickel
Holmium
Carbon
Iron
11
What are orbitals
different ways spaceships can orbit earth.
the orbits of different planets in the solar system.
mathematical functions that show probable electron location.
the path that electrons take around the nucleus.
12
What is supersymmetry?
an obsession with symmetry.
each fermion has a bosonic partner and likewise for bosons.
ultra symmetric objects.
another name for OCD
13
What are Wolf-Rayet stars?
stars that have weak stellar winds.
The sun is a good example.
a rare class of very hot stars with unusual spectra.
Stars that were discovered by Wolf Rayet.
14
Why is Tantalum-180m a stable nuclear isomer?
Because the excess energy goes to binding the nucleus.
Because reasons
A large spin gap between the ground state and excited state.
A nuclear anomaly that requires further examination.
15
What is the antiderivative of lnx
(lnx)/x
xlnx^2
xlnx-x
1/x
16
what is the derivative of sin(x^2)
Why calc?
-4sin(x)
2cos(x^2)
2xcos(x^2)
17
How does the warp drive work?
uses mysterious substances to violate universal constants
Warps spacetime around the vessel to achieve FTL travel
it uses ultra powerful boosters to get it to lightspeed
uses wormhole metric to go from one place to another quickly
18
True or false: Francium is predicted to be more reactive than Cesium (Francium is under cesium)
False
True
19
What theory has to be correct if there are multiple universes?

21
What is one way to cure aging?
Become extremely healthy and take anti-aging pills.
Use CRISPR to maintain a constant telomere length.
Stop eating red meat and eat the healthiest foods.
Rely on your religion.
22
Why would different universes have different fundamental laws of physics?
The CY manifold has many variations making unique particles.
The CY manifold will change size making an apocalypse.
Different universes develop differently.
There will be an extra class of particles.
23
What is Beta decay?
IDK
Radioactive decay that changes quark flavor via weak force.
when the nucleus loses energy by emission of a gamma ray.
the emission of an electron from the nucleus.
24
Why is gold the color gold?
Because gold is just beautiful.
My brain hurts.
gold reflects a lot of blue light.
relativistic effects alter the energy between the 5d and 6s.
25
What causes alpha decay?
the nuclei kicking out nucleons because they are too large.
When heavy elements have a meltdown.
Too advanced 4 me.
pre-formed nuclei that quantum tunnel their way out.
26
Why are there 3 classes of elementary particles?
There are 3 holes in the CY manifold for strings to vibrate.
Just because there are
IDK
there are 3 possible string oscillations for each class.
