One of the most startling consequences of time dilation is that a moving clock ______________ relative to a stationary observer.

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. 

Based on the concepts of Special Relativity time travel is...

• not possible

• possible only in the ability to travel into the past.

• possible only in the ability to travel to the future.

• possible to travel either forward or backward in time.

We are able to see into the past.

• True

• False
