Hello wonderful person this is Anton and in today's video we're going to try to
turn our beautiful Jupiter into a star can we do it let's find out welcome to
What Da Math
so actually one of the most common questions that I receive on the channel
and on Facebook is to basically try to turn Jupiter into a star similar to our
Sun that you see in the back there but then we can't we can't for many reasons
and one of those reasons is because I think people that often asked this
question don't realize how many Jupiter's we need to combine together to
create a star so let's actually start by answering
that question how many of these do you need to combine into one large object to
turn this into even the smallest star we're going to create a new simulation
and in this simulation we're just going to start placing Jupiter's right next to
each other so they actually start colliding so let's put a bunch this is
five this is ten and let's wait for all of them to combine into one large mega
Jupiter if they start escaping we can go into power and disable out all
velocities basically once you hold on velocities everything will combine into
its one large object so this is a Jupiter that's supposed to be about ten
masses of original Jupiter it's unfortunately not as big I think because
we lost a lot of the stuff to do those collisions but we're just going to cheat
and make it ten masses of Jupiter so this is a standards together all right
how big is it compared to the original Jupiter not that much bigger in terms of
at least a volume so volume wise there are still relatively similar okay let's
hold all velocities again and please ten more Jupiter's around the mass of
Jupiter making this a double massive Jupiter
so hopefully this will now have 20 masses of Jupiter but it doesn't it once
again because of the collisions all of this material gets dispersed into space
we might be able to recapture it by doing this let's see if it actually
happens so this is now supposed to be about 20 masses of Jupiter and still
just the gas giants it's still not a star
and if I actually accelerate this you can see that all of this material falls
back into this massive object increasing its mass quite dramatically making it a
little bit warmer than before but still not as hot as it should be
we're going to make this 20 masses and there you go we're going to wait for it
to cool down as well it's sort of spinning on the wrong axis but that's
okay and there you go so this is our super massive 20 masses of Jupiter
Jupiter okay we're not done yet this is still not even close to being a star
let's please I guess 20 more yeah let's do that so here we go 20 more Jupiter's
sudden explosions really really fast a lot faster than I actually was hoping
for but that's okay and hold all the LA cities combined all the material into
one and hopefully get okay it's 38 masses we're going to go for 40 masses
of Jupiter very very fast with spinning objects very very interestingly looking
but once again still not a star even after 40 Jupiter's were still not in a
star formation mode let's put 20 more making the 60 this time we're going to
make this a little bit more dramatic we're going to actually decrease time
and just watch all these super massive Jupiter's collide with this ultra mass
of Jupiter and possibly cause some blocks of the game as well yeah they're
not really doing so well and they're actually colliding with one another as
well so it's kind of interesting but if I hold all the AH settees they'll always
start coming toward us and eventually hopefully we'll combine into one massive
object so let's wait for this to happen and by the end we should have an object
that's about 60 masses of Jupiter now it is going to be a star
well what's let's see take a guess what do you think do you think it will be a
star I am pretty sure it's not going to be a star and you're going to find out
why in a second and there is that final suction of all the matter including the
last object that we still haven't collided with
and at the end we'll get a total mass of 60 Jupiter's now at this point this is
now classified as a brown dwarf it's still not a star it's a little bit more
massive than a gas giant but it does not have a nuclear reaction on the inside so
it's not technically a star star you can see decreased in size because of its
sudden increase in mass and it's now even possibly smaller and volume than
the actual Jupiter so to compare this to to a beautiful
Jupiter you can see that it's actually smaller in terms of size but not in
terms of mass it's a lot more dense that's why it's volume is so much lower
okay so let's put 10 more make it a 70 there is a 70 Jupiter's and once they
combine into one which will hopefully happen once all of these bugs are
resolved here I think something got stuck in on the inside but anyway once
they all combined we should have a total mass of close to 70 Jupiter's and this
might initiate the nuclear reaction if everything goes right we might be able
to create a star and looks like we lost some mass again we need to try to regain
that mass by reabsorbing it by holding all velocities again and at the end this
will hopefully become a star of some sort so we're currently at 53 55 60
message of Jupiter it's increasing dramatically and will this become a star
we're very very close to 70 masses of Jupiter now we're observing more and
more matter as it sort of orbits around us and at this point maybe just maybe
nothing still nothing we're over 70 masses of Jupiter and we're still not a
star so this really kind of shows you how much more massive our Jupiter would
have to be before it actually turned into a star okay let's go to 75 we're
going to start placing them one by one here it goes one
it's only been eaten away by this object in a very interesting manner and I think
it's actually losing a lot of the mass - I don't know what's happening to that
mass but it's definitely disappearing somewhere and this is 75 masses in total
once everything is absorbed we should have some kind of a indication whether
this is still a brown dwarf or a star right now it's kind of hard to tell and
here we go this is 75 and we're still a brown dwarf we may need to go to even in
the higher mass because this is still a brown dwarf as you can see it's
shrinking in size because its density is increasing quite dramatically and it's
basically a very very very compact gas giant like object that is technically
known as a brown dwarf hmm we might need to get 5 more going but what's
interesting though is that this object is actually now a lot hotter than a
typical gas jet would be so its temperature is about 1400 degrees
Celsius and it seems to be stuck at that
temperature so in other words it it actually radiates quite a lot of heat
and you could potentially even have habitable planets around it or in this
case I guess it would be habitable moons okay we might need to place a few more
Jupiter's for it to turn into an actual star we're going to start with one or
actually let's put two at a time so this is 77 and this will be 80 so let's see
if we can now maybe officially turn this into a star by placing 80
Jupiter's into one and so here goes nothing this is now going to be a very
very massive object once it combines all of the mass into one and any second now
let's see what happens to this it's still just a brown dwarf 60 70 75
and still absorbing some of the masses it's sort of jumping out because of all
the collisions and there we go there is that star at 78 masses of Jupiter now
that's just a a Red Dwarf it's a star that is very very very small
in comparison to our Sun very similar to the recently discovered Trappist one
it's also very active star so it's very unlikely that would find any habitable
planets around it but it's not that much bigger than Jupiter but what this should
have showed you is how difficult it is actually to turn a gas giant into a
start you need 78 Jupiter's four for us to have another star in our solar system
so if I actually go back to our solar system and look at our Jupiter I need to
increase its mass 78 times for it to actually turn into a star this would be
quite impossible for two reasons one is that a total mass outside of our Sun
basically if I were to collect all the materials outside of our Sun no planets
asteroids ice comets all of the moons everything together it wouldn't even
give us to Jupiter's in total to get 78 we need to get a lot of stuff from
somewhere maybe it's 79 is it 79 yes it's 79 we need to get a lot of
stuff somewhere else from the outside of solar system where that's going to
happen we don't really know but essentially it's quite impossible to
turn Jupiter into another star but it'll be fun to have one though and we would
then become a binary solar system and if I look at Earth now its temperature will
actually start increasing quite dramatically because now we have two
stars on opposite sides of our planet one variant that's right there somewhere
that's illuminating our dark side and one a regular star the Sun so this also
means that with time the temperature on planet Earth will actually become much
hotter than it currently is and there is the red dwarf Jupiter
that's illuminating us from the outside I'm going to run this for maybe a few
months just to see how temperature changes and just to see what else
happens in our solar system as the supermassive giant red dwarf star
Jupiter starts causing all kinds of trouble here and interesting with the
temperature on our planet has actually changed that much but the orbits are
changing quite dramatically and that's probably because Jupiter is slowly
Jupiter the star that is is slowly stretching all of the orbits of inner
planets making them a lot more elliptical including of course our
planet Earth which is now going to have a slightly different orbit from before
and anyway so that's all I wanted to show you in this video I wanted to
experiment with Jupiter and turn it into a star explain to you why it's actually
kind of impossible in practically speaking and also give you an idea what
would happen if Jupiter did become a star
so this binary system now has two stars orbiting around one another anyway come
back tomorrow to learn something else interesting something else new something
you didn't know before and potentially subscribe which is to have it share this
video with your friends or someone who enjoys learning through video games and
most importantly let me know if there are any other hypothetical scenarios
you'd like me to explore or something else you would like me to make in
universe a box I'll see you guys tomorrow
space out and as always bye-bye let's accelerate it's a little bit
faster and see what kind of trouble starts occurring on our own in our solar
system
you
