hello and welcome back to life's biggest
questions I'm Ron McKenzie lafurgey
following the conspiracies regarding the
impending disaster at the hands of the
all but disproven rogue planet Nibiru
many have turned their thoughts to the
idea of large-scale impact events while
humanity has avoided this eventualities
us far it could be that one of these
days a rogue planet will come back and
mess things right up what would happen
if we were struck by one of these
planets
let's explore if you liked this video
and want to see more like it check out
our biggest what-ifs playlist on the
channel now get ready it's time to ask
the question what if a rogue planet
crashed into Earth the first question we
should ask is what is a rogue planet a
rogue planet is a planet that drifts
alone often orbiting around a galaxy
rather than orbiting around a star like
we're used to seeing this means that the
trajectory of one of these rogue planets
could intersect with earth which would
lead to disastrous consequences it's
believed that the Milky Way galaxy could
have billions of these drifting about
just waiting to crash into an
unsuspecting planet as previously
alluded to a group of conspiracy
theorists were claiming that Nibiru the
mysterious planet X was one such planet
and was coming to destroy the earth
first it was going to come on September
23rd and it didn't then it was supposed
to come on November 19th danda didn't
despite all evidence pointing to its
non-existence these people continue to
cling to their theories moving on to
claims that Nibiru does exist but the
government is hiding it from us using
chemicals sure it sounds like a fourth
graders science fiction book but it does
bring up an interesting question what if
a rogue planet actually did crash into
us well this may have already happened
while there is some disagreement the
prevailing scientific idea is that the
moon was created thanks to the rogue
planet Thea feyo was roughly the size of
Mars which is about half the size of
Earth and it's believed to have crashed
into the earth this launched chunks off
of the earth into space which eventually
gathered together due to gravity to
create the moon so if a rogue planet
were to crash into Earth we could end up
with the second moon but what would this
mean for the inhabitants of Earth as you
likely expect this kind of impact event
would be absolutely disastrous to life
on Earth
considering the object that killed the
dinosaurs was roughly 7 or 8 miles wide
while most planets are over a thousand
times that size it's clear that we
wouldn't have much of a chance of
survival scientists have determined that
an object need only be roughly a hundred
kilometers in
ammeter to wipe out all of humanity and
100 kilometers is miniscule compared to
the size of most planets if we were
struck with another mars-sized planet
like may have happened 4.5 billion years
ago the energy created would heat the
earth to incredible levels turning the
surface of the earth into an ocean of
magma sounds pretty terrible but at
least all my years of playing the floors
lava would finally pay off han jokes
aside this means that the vast vast
majority of life on Earth would die
leaving only certain species of
extremophiles that can survive in
incredibly hot environments even those
extremophiles might have trouble in the
intense heat created by the collision a
good chunk of the earth would be
destroyed and with a large enough impact
it could even be knocked out of its
current orbit however we can take solace
in the fact that most scientists believe
this to be a highly unlikely occurrence
while these rogue planets are somewhat
difficult to detect due to their
darkness one fact can put our minds at
ease space is really really big well it
may be that there are billions of these
planets in our galaxy if they are
divided across the galaxy they would
appear highly infrequently odds are that
there isn't more than one within a
hundred cubic light-years of our planet
for reference one light year is ten
trillion kilometers that's an awful lot
of room to miss even taking into account
higher numbers in Planet dense areas
making it incredibly improbable that it
would happen that said if it's happened
before it could happen again and now we
return to our question what if a rogue
planet crashed into Earth well the short
answer is the earth would get messed up
and all life would die an impact event
of that size would release so much
energy that pretty much everything would
be obliterated thankfully this seems to
be highly unlikely since the earth is
fairly small relative to the enormity of
the galaxy but hey if it does happen the
earth might eventually have a new moon
so it's got that going for it which is
nice
thank you for watching lights biggest
questions I hope this was interesting

you to look into it further on your own
