QUESTIONS AND ANSWERS | A+

why cant we travel at 99.99% the speed of light - correct answer -
not enough propulsive energy and shielding against radiation.
hypothetical particles that could move both faster than light and
backward in time are called - correct answer -tachyons
how may observers in universe see us from their point of view -
correct answer -they see us living in slow motion
what does the concept of time apply to - correct answer -events
and entities within the universe, not the universe as a whole
where does spacetime exist - correct answer -WITHIN the
universe

as the speed of an object approaches the speed of light, its
momentum? - correct answer -approaches infinity
photons of light are - correct answer -massless
a piece of matter, even at rest and not interacting with anything
else, has an "energy of being" this is called - correct answer -rest
energy
E=mc^2 what does C^2 mean - correct 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 - correct answer -its mass
The filament of a lightbulb energized with electricity has - correct
answer -more mass than when turned off.
