La Tierra el Centro del Universo- Comprobamos un modelo antiguo - Universe Sandbox

For more than a thousand years people believed that the Earth was at the center of the universe According to the geocentric model the Sun Moon and planets revolved around a stationary Earth In this video we will recreate that vision in Universe Sandbox and we will see how the universe looked to ancient astronomers I will present a couple of variations of this experiment In the first case I will simply swap the positions of the Earth and the Sun And well basically I replace the Sun with the Earth and the Earth with the Sun I will also block the Earth's ability to move so that it remains in one place forever And I will add to the Earth its satellite the Moon Here it is the Moon And now I start the simulation and let's see what happens The Sun seems to have entered orbit but Mercury rushed directly toward it And the Moon broke away from the Earth while the Earth remains there motionless in the center Well anyway The movement of the Sun has begun and the planets are starting to follow it Basically this will cause the destruction of the Solar System Well at least partially that is certain But will there be total destruction of the System Well Jupiter no longer orbits the Sun Venus seems to be moving in its direction Well in the end you'll see it for yourselves everything In summary the Solar System will simply be destroyed There goes Mars there goes Saturn If Earth and the Sun simply swap places this is what happens And the Earth simply remained here in the center And with it as if everything is clear but it began to freeze Miren a completely frozen world The temperature here has dropped extremely it is already at an average of minus 204 degrees And near the Sun we see this image Mercury entered a very elongated elliptical orbit around the Sun And here the Moon also orbits by the way in the opposite direction to the way Mercury orbits the Sun as you can see And a series of main belt asteroids As for the planets well I still see Ceres But of the main planets none remain in orbit anymore Only Mercury the planet closest to the Sun The rest as you can see simply disperses In the second case I have already created such a system where the Earth is stationary at the center of the Solar System Now I will show them to you Here basically I approach the center of the Solar System if it can still be called that or the Earth system right And here we see Earth right in the center there the Moon orbits Here orbit Mercury Venus and the Sun instead of Earth I will speed up time and you will see that the Sun is actually orbiting the Earth How did I do it you may ask Yes I had to struggle a bit it was very difficult but now I will explain everything Take for example the planet Jupiter As you can see here its mass and radius fully correspond to its characteristics But in order for it to orbit the Earth yes I had to work quite hard really The first thing I did was drastically reduce the mass so that it would orbit the Earth so to speak Then I returned that mass But in order for it to orbit it was also necessary to disable the attraction of other objects here And with the Earth I did the opposite so that it would have the ability to attract other objects but that the Earth would not be attracted by other objects Well as you can see the orbits here are stable The orbits of Uranus Neptune and Pluto have not yet been fully drawn Because they move very slowly around the Earth They move at a very low speed because the Earth has little mass Well the closer to Earth the faster everything spins In our simulator time passes at more than 100 years per second Let's take the orbit of Saturn as an example I will show you the movement of Saturn It moves at a speed of only 16 meters per second It is very slow Mercury of course orbits more quickly but even here its speed is low Only 85.3 meters per second In the normal solar system it moves much faster I will also show you the habitable zone Here is the situation Since the Earth and the Sun are at the same distance one astronomical unit the Earth should have normal conditions just like in a normal solar system But Mercury Venus Mars and the other planets can receive different temperatures from the star at different times Let's see what happens with Earth I will hide the atmosphere and the clouds As you can see at this moment the northern hemisphere of the planet receives more sunlight While the southern hemisphere barely receives it And here a lot of ice has formed everything is frozen Even the south of Africa and the southern part of South America And the average temperature of the Earth is slowly decreasing And do you know why this happened Because the Earth is stationary in the center And the Sun moves in its orbit at a very slow speed It turns out that by the time the Sun moves to the other side of the orbit to warm the southern hemisphere Our northern hemisphere will have time to warm up a lot and the southern one on the contrary to cool down a lot I hope I have explained it clearly I sped up time to 30 years per second He had to speed it up to clearly show how this slow movement of the Sun affects the Earth's and other planets' climates Yes it is possible that the weather is not perfectly calculated but they will still be able to get a general idea And again near the Earth See how the temperature fluctuates as the Sun moves along the ancient orbit of the Earth And we see that now our southern hemisphere is freezing while the north is completely thawing And now it will be the opposite Yes as you can see the north is freezing and the south here is thawing Well anyway This is the new seasonal change on Earth but for it to happen a long time has to pass Much much longer You can calculate it yourselves They pass 30 years per second Probably they have to pass hundreds of years for summer to arrive here for example in the southern hemisphere The average temperature on Earth as far as I can tell fluctuates between minus one degree and plus six degrees Celsius on average And yes we can see how far the snow reaches to the south It's something really serious Well I think in a world like this Only in the equator would it be possible to live normally At least snow and ice do not reach there The probability of life on such a planet ranges from 84 to say 90 percent Do you see how different everything is now That is exactly how people imagined our solar system in the past Let's take a brief look at Mercury On Mercury the temperature fluctuates between more than 55 and less than 51 degrees Celsius Now Venus The surface is not visible at all Let's see what's on the surface Well the usual Venus with its molten surface Let's see how the temperature fluctuates on Venus 174 degrees Celsius was the minimum temperature The maximum at the closest point to the star was over 800 degrees Let's also see how Venus will warm up with the atmosphere and clouds activated Well it didn't look very good how everything heated up on the surface As for the Sun I'll show it to you To make you believe me I will fly there And these are its characteristics As you can see here its mass and radius have not changed The temperature has not changed And the luminosity has not either That is the Sun is like a normal Sun It simply orbits the Earth Yes it sounds incredible I will reactivate the habitable zone so they can see how this red area of the Sun and the green one move along the orbits of the other planets That is why this temperature fluctuation occurs When for example Venus enters the red zone it even approaches the black zone There it has the highest temperature The same happens with Mars and Mercury at certain times Well it's clear that Jupiter and Saturn won't be affected as much by this But even so there should be a slight temperature fluctuation Now come to Mars Oh oh As it approaches the star how much it has changed And even vegetation appeared for a moment Did they see that there was a green strip But now it is minus 159 degrees Celsius And the temperature starts to rise again Now Mars is approaching the star The temperature reached almost 100 degrees Celsius Wow what a change of seasons on Mars Although it didn't freeze here Oh let's take a look again Well I will move a bit further Oh there it is That is the conditions are suitable for vegetation Well the simulator will immediately show the vegetation if it is possible in that place Well in summary that's about it If we start time again Mars will freeze once more Now come to Jupiter I will speed up the time even more Here I see that the temperature is no longer fluctuating as much About 19 degrees give or take The average is about minus 165 degrees Celsius Now come to Saturn In it the temperature no longer fluctuates as much as on Jupiter It only varies by about 5 degrees either way And on Uranus I think it won't fluctuate much Well we see less than 219 degrees and initially it no longer changes Now come to Neptune The temperature there has reached minus 229 degrees Celsius Here is the dwarf planet Pluto It is 238 degrees colder there on Pluto Now I will return to Earth I want to descend to its surface here in Australia And let's look at the sky how the star looks from here Here is the sun it is very bright here I turned off the space glasses If I activate the display of course the sun looks like this And now we have the night sky and perhaps we will see some planets I just saw the Moon and it still looks very small but in Universe Sandbox something doesn't add up with the sizes Although it is at the correct distance from Earth I activated the labels to see where these planets are Here I see Jupiter and next to it is Venus But they are not visible at all only the labels indicating where each planet is From here you can also see Pluto where it is located Well I don't see anything else around here This is what would happen if the Earth were at the center of the solar system It was a brilliant experiment If you liked it give it a like and leave a comment Thank you very much
