Question 2 of 21

E=mc2 came from Einstein's special theory of relativity, giving birth to the atomic age.

... It's a fact! This famed equation, which gave birth to the atomic age, was published as part of Einstein's special theory of relativity.

Question 3 of 21

Einstein's general theory of relativity was published in 1905.

... Einstein's theory of relativity was a two-parter. The general theory of relativity was published in 1916, 11 years after the special theory of relativity.

Question 4 of 21

The fact that the universe is expanding was announced for the first time by Edward Hubble.

... Edward Hubble discovered the universe is expanding by measuring redshifts in distant galaxies. Could this be why a telescope is named after him?

Question 5 of 21

The big crunch is the theory that the universe will one day stop expanding and eventually collapse in on itself.

... Also known as the closed universe scenario, the aptly named big crunch theory explains that the universe will throw itself into reverse and eventually re-collapse.

Question 6 of 21

Einstein's eight field questions were published in his general theory of relativity.

... Einstein wrote 10 field questions. They were used to prove, among other things, the existence of black holes.

Question 7 of 21

Physicists used emitter clocks to discover that time moves faster at higher elevations.

... Tick-tock, it's atomic clocks! They're the most accurate in the world and have shown that time passes a tad bit quicker at higher elevations.

Question 8 of 21

Traveling at the speed of light would, in theory, allow for human time travel.

... Although we have yet to master this skill, it's theoretically possible to time travel if we could move at the speed of light.

Question 9 of 21

A gravitational wave is a change in the shape or curvature of space-time.

... Space-time can change with a wave. It occurs when two huge moving masses interact, causing waves to ripple outward from the source.

Question 10 of 21

Cosmic mirages are another name for gravitational lenses.

... Gravitational lensing produces distortions, which can magnify or multiply images. Hence the name cosmic mirage.

Question 11 of 21

Weak lensing occurs when light from a galaxy passes another massive galaxy, galaxy cluster or dark-matter concentration.

... It's true! Weak lensing occurs when light from a galaxy passes another massive galaxy, galaxy cluster or dark-matter concentration.

Question 12 of 21

J1614-2230 is the largest neutron star discovered to date.

... While it could use a catchier name, J1614-2230 is the largest neutron star we've discovered so far. It's 20 times more massive than our sun!

Question 13 of 21

Quasars are extremely bright. Some look like they're blinking, but they're actually emitting light in pulses.

... This one's fiction! While quasars are very bright, it's neutron stars that look like they're winking.

Question 14 of 21

German physicist Max Planck first proposed quantum theory.

... It's a fact! Max Planck first proposed quantum theory, and Albert Einstein built upon his theory to establish the field of quantum physics.

Question 15 of 21

Light is not a long, continuous wave. It consists of tiny particles called protons.

... It's a fact. Light consists of thousands and thousands and thousands (keep counting) of protons.

Question 16 of 21

H.G. Wells wrote "The Time Machine," which was published in 1890. In it, a man travels 800 years into the future to see the fate of the Earth.

... H.G. Wells did write it, but "The Time Machine" was published in 1895.

Question 17 of 21

It seems odd, but could it be true that a ship zipping through space at warp speed would cause a black hole?

... Black holes are the result of the death of a massive star. While it's fun to think of a ship ripping a huge hole through space, it's impossible.

Question 18 of 21

Using Einstein's equations on gravity, German physicist Karl Schwarzschild proved the existence of black holes.

... Karl Schwarzschild found a solution to one of the gravity equations in Einstein's general theory of relativity and used this equation to prove the existence of black holes.

Question 19 of 21

We don't know everything there is to know about time, but we do know this: It only moves forward and everything moves at the same speed.

... Like everything in life, time is relative. It speeds up or slows down depending on how fast one particular object is moving relative to another object.

Question 20 of 21

Albert Einstein supported the findings that the universe is expanding from the moment they were announced and wrote about it in his paper called the Cosmological Constant.

... Actually, the Cosmological Constant was Einstein's theory on why the universe isn't expanding, but is static. He later recanted this theory.

Question 21 of 21

The U.N. created a special agency, nicknamed "Atoms for Peace," to promote the responsible use of atomic energy technology.

... In 1957, the U.N. created the International Atomic Energy Agency (IAEA), also known as "Atoms for Peace."
