• Time dilation

• Space-time

• Length contraction

• Relativity

Time and space as one entity is known as

• Time dilation

• Space-time

• Length contraction

• Relativity

What happens to time when an object travels at the speed of light?

• Time stops

• Time slows down

• Time speeds up

• Time stays the same

For an object to go back in time, what speed does it need?

• Same speed as the speed of light

• Slower than the speed of light

• Faster than the speed of light

Which of the three states "Nothing is ever at absolute motion or absolute rest. Objects move relative to each other.

• Special Relativity

• General Relativity

• Classical relativity

• Relativity

There are two twins on Earth. One flies off on a spacecraft traveling 90% of 'c' while the other twin stays on Earth. Which of the following is TRUE?

• The twin on the spacecraft will age more slowly than the Earth-bound sibling

• Time in each frame of reference proceeds differently at different speeds

• This is an example of the 'Twin Paradox'

• All answers are true

Who was the creator of a special theory of relativity?

• Albert Einstein

• Marie Curie

• Sir Isaac Newton

• Michelson and Morley

We do not usually observe relativistic effects in our daily lives because 

• we are moving at speeds much less than c. 

• we are much larger than atoms. 

• we are much heavier than elementary particles. 

• we are much lighter than stars. 

E=MC² is a formula that...

• describes how mass warps spacetime

• describes the relationship between acceleration and gravitational pull

• describes mass and energy as different manifestations of the same thing (like 2 sides of a coin)

• describes the relationship between the event horizon and the singularity of a black hole
