this episode of life noggin is brought
to you by aj+ hey there I'm black oh I'm
Evan you can call me the nerd runner and
today we're teaming up in this video to
debunk eight common movie myths that run
rampant in Hollywood Hollywood is known
for often bending the truth when it
comes to science so we want to set them
straight
alright let's do this a commonly used
movie myth involves having lasers in
space the colorful battle scenes are
nice to look at but they bring up a lot
of problems firstly in space we would
not be able to see the laser beam if you
shine a laser pointer through a medium
that scatters light you could see it but
remember space is a vacuum there's
nothing there to scatter the light so
you wouldn't even be able to see the
laser until it reaches your target and
on that note in some movies the lasers
seem to take a second or two to reach
the target but keep in mind lasers are
just light which travels at a specific
speed the speed of light therefore these
space battles would not only be
invisible but extremely short a science
myth that came about from the Star Wars
films is that asteroid belts are really
dense dense enough to require careful
navigation in reality the asteroid belt
located between the orbits of Mars and
Jupiter is so large that if you were
standing on an asteroid it would be
difficult to see its neighbor without
the use of a telescope think about it
this way while it's estimated that there
are millions of asteroids in the
asteroid belt there is also a massive
amount of space that they occupy it's
unlikely that you'll find them all
grouped together in one relatively small
area a common trend in action movies is
to shoot a lock to make it open now this
is not completely incorrect but it's
incredibly oversimplified most handguns
won't quite do the job but a
high-powered rifle will however the
shrapnel that comes from flying off the
lock could do some serious damage
especially if the lock is shot at
point-blank range in Captain America the
Winter Soldier which is an awesome movie
we see cap free-falling without a
parachute and landing in the water
seemingly unscathed while we aren't sure
of his exact speed we can assume that it
was around terminal velocity when he
enters the water he suddenly starts to
decelerate resulting in a force of
potentially hundreds of G's a force like
that can cause broken bones and even
death but then again he is a character
in the Marvel Universe so he'd probably
handled
of course we can't have an action movie
without an explosion and where there are
explosions there are people casually
walking away from them I'm talking to
you every action star ever with these
movies fail to consider is the damaging
shockwaves of the explosion and any
shrapnel that can come flying around
immediately after an explosion the shock
waves can travel many times faster than
the speed of sound and they're usually
followed by very strong winds which
working together can knock down many
structures in among 1.3 shockwave the
speed of wind is already stronger than
the fastest tornados wind speed speaking
of explosions movies make it seem like
all you have to do to make something
explode is shoot it but it's not
actually that easy if you try to do this
with just a normal gun it won't work
because the bullet does not provide
enough of a spark to ignite the gasoline
an explosion occurs when a substance
rapidly produces gas and heat in order
for the fuel to combust and cause an
explosion the reaction requires some
type of ignition and a bullet simply
won't do the trick
thanks for the logs amnesia is also used
incorrectly in many films resulting in
the character losing their self-identity
however in real life most people with
amnesia primarily have problems with
their short-term memory making them
unable to retain new information also
even though head injuries can result in
temporary confusion and problems with
memory they usually don't result in
severe amnesia the type of amnesia that
movies like to over-exaggerate it's
called retrograde amnesia which people
are not able to recall events that
happen before the onset of the amnesia
however this is normally caused by
damage to the hippocampus and temporal
lobe in the brain lastly we can't make
this video without mentioning cinematic
car chases one of my personal favorites
is the yacht scene from too fast to
furious in this scene a car axle as it
jumps over the water to land on a yacht
the car passengers are of course
uninjured granted it is not physically
impossible for the car to reach the
yacht as long as they were traveling at
the correct speeds but it's highly
unlikely that no one in the car was hurt
the force of the impact could easily
have caused any number of injuries
including whiplash punctured lungs and
concussions let alone a few cuts and
bruises ah but in Hollywood movie makers
can make their own laws of physics it
might not be the truth but it's
definitely entertaining
one movie myth that we didn't mention
let us know in the comments and make
sure you guys come back every Monday and
Thursday for a brand new video hey
everybody if you want to see my in-depth
analysis of Martin Scorsese's the wolf
of Wall Street

and this has been life noggin don't
forget to keep on thinking
