SOLUTIONS
why cant we travel at 99.99% the speed of light - (ANSWER)not enough propulsive energy and shielding
against radiation.
hypothetical particles that could move both faster than light and backward in time are called -
(ANSWER)tachyons
how may observers in universe see us from their point of view - (ANSWER)they see us living in slow
motion
what does the concept of time apply to - (ANSWER)events and entities within the universe, not the
universe as a whole
where does spacetime exist - (ANSWER)WITHIN the universe
as the speed of an object approaches the speed of light, its momentum? - (ANSWER)approaches infinity
photons of light are - (ANSWER)massless
a piece of matter, even at rest and not interacting with anything else, has an "energy of being" this is
called - (ANSWER)rest energy
E=mc^2 what does C^2 mean - (ANSWER)conversion factor between energy units and mass units. it
converts the measurement of mass to the measurement of equivalent energy
A change in energy of any object at rest is accompanied by a change in - (ANSWER)its mass
The filament of a lightbulb energized with electricity has - (ANSWER)more mass than when turned off.
E=MC^2 is the ratio of - (ANSWER)rest energy to mass
