1. Can energy become matter?
Yes
No
2. If you were moving just below the speed of light, could you see light moving beside you, moving slightly faster than you?
Yes
No
The light would still appear to move at the speed of light
3. Does gravity affect time?
Yes
No
4. Can one piece of matter be in two places simultaneously?
Yes
No
Electrons, when behaving like waves, exist in many places at the same time.
5. Is it possible for humanity to know everything?
Yes
No
Somethings are moving away from us so quickly, that we can never know they exist
6. Which of these things does NOT act like a wave
Energy
Light
Matter
Space
7. Can something have infinite density?
Yes
No
Called a singularity
8. Can light change speeds?
Yes
No
Light going through matter goes at different speeds
9. Which of these things can NOT happen with subatomic particles
They can appear in one place, then another without having been in the space between
They can consume other subatomic particles
They can partially exist
They can turn into other subatomic particles
10. Can matter be destroyed into nothing?
Yes
No
11. Which of these is a consequence of the many worlds interpretation?
The universe could cease to exist at any moment
You could never die
Nothing in the universe can be proven the exist
Time is not constant
Every time you die, your consciousness would be brought to a dimension where you have not died
12. Is antimatter affected by gravity?
Yes
No
But it might fall up instead of down
13. Two spaceships leave earth in opposite directions, each traveling 0.9 times the speed of light. Could these ships communicate with each other?
Yes
No
Even though, from Earth, these spaceships would appear to be moving away from each other at 1.8 times the speed of light, the relative speed between them would be less than the speed of light
14. What shape is the universe?
Has no shape
Round
Flat
All shapes simultaneously
15. As an object approaches the speed of light, what does the mass approach?
Zero
Infinity
Mass does not change
Simultaneously zero and infinity
16. Do you exist?
Yes
No
Nobody knows
You are the only thing that you can definitively know to exist

Interesting quiz but I have a couple of points, which I could be completely wrong about but hopefully someone will set me straight if I am:

4. The probability of an electron being in a given position is determined by it's probability wave function which has a value for every position in space at any one time but it's actual position is only determined when it is measured and the wave function collapses (but then it will be in a specific place). Or are you referring to the double-slit experiment? That shows that the particle's wave interferes with itself due to wave-particle duality (existing as a probabilistic wave before being measured but as a particle once measured).

10. I thought matter is destroyed when it is converted into energy?

14. The topology of the universe depends on the intrinsic background pressure of space and we haven't yet been able to ascertain whether it is slightly positive, slightly negative or perfectly balanced...

...

15. I thought was a trick question as nothing with mass can be accelerated to light speed. Photons are the only particle known to move at light speed and they have no mass.

You may well know that I'm wrong about all of these, especially as you've made a quiz about it, in which case sorry for doubting!

First, let me state that I am, in no way, an expert on quantum physics, so what follows may also be incorrect. So:

4. You are essentially correct. I wasn't thinking of the double-slit experiment when I wrote the question, but that works. I've added an addition explanation which may clear things up.

10. That's true. I will change the wording of the question to be more accurate.

14. I was relying on the inflationary theory, which I believe is widely accepted (could be wrong). This theory does confirm that the Universe is flat.

15. You are also correct, I will change the wording of this question

Just thought as well for question 10 - when a particle and its antiparticle collide they annihilate one another and become nothing, not even energy (at least I think that's what happens), which also kind of affects Q 9

That might only occur with virtual particles though, I'm not sure.

Also, Q. 16 is more in the field of epistemology / metaphysics than quantum mechanics

I enjoyed the quiz though :-)

I am not 100% sure that #10 is correct due to quantum fluctuation, but I guess it really depends on how you interpret the question.

I suggest this alternative question: "Can matter arise spontaneously from a vacuum?". The answer, of course, is yes, and it may be how our universe began.

Several of these questions are about relativity, not quantum mechanics. It's not the same at all.

Well, I don't agree with several questions... The fact is, that quantum mechanics is a mathematical theory that fits the data pretty well, but has anyone understood it? I don't know... ^^ In my opinion, it's basically about the impossibility of making perfect measures, because we are too big and we are made of the same particles as those we try to measure. Thus the theory of operators and probabilities, which mathematically represents the fact that we perturbate reality when we measure it. I think we always only see a projection of reality and not reality itself.

Anyway, as for those questions...

4 : As I said, the theory says that you can't measure speed and position at the same time, or energy and time at the same time. Particles are seen as wave packets, not as points. Then again, it's a theory of probabilities... the wave function is meant to tell where the particle could be, it has to be fed to an operator, and what we measure and interpret as reality is an eigenvalue of the operator. So, can particles exist as various places at the same time... nobody knows, and I'm not even sure if the question has a meaning...

7 : I don't agree. A singularity is not part of spacetime.

8 : Nope, light always moves at the speed of light. What "slows it down" is the numerous interactions with the particles of the material it crosses (which also cause scattering). So you're just talking about the effective speed of light in a given material, not its true speed.

11 : I often thought it might be the case, but I seriously doubt it... but this is rather philosophic than scientific (as is the last question, though, of course, I'm sure I exist, by definition of existence ^^).

12 : No, antimatter is affected by gravity in the same way as matter. Mass as no sign, it's purely attractive (at least for timelike particles...).

14 : It depends on what you call a shape, but the universe is definitely not flat, that's all the point of general relativity...

15 : Mass is a constant. I don't like the interpretation where particles are said to have a higher mass at higher speed. Call it rest mass if you want, but it's the only value that has an interest. It's better to say that E= mγ(v) c².

1. Technically, energy cannot become matter, as matter is already energy.

4. Electrons, along with any particle, can exist as a wave. However, that is not the same as existing in multiple places as once.

7. It is unknown whether the singularity at the center of black holes truly is infinitely dense.

8. When light is being refracted through matter, it is being absorbed and re-emitted by the matter. This "slows" the light down by creating a large path.

9. Protons can absorb an electron and anti-neutrino to form a neutron.

11. The Many Worlds Interpretation does not discuss consciousness. This is a pseudo-scientific thought experiment of quantum mechanics known as quantum immortality.

Another quality quiz Wolfie. Although some of the answers can be contested, it is a very amusing diversion.
