What If The Sun Was Smaller Than the Earth? #Shorts

What If The Sun Was Smaller Than the Earth? #Shorts



You’d need 1.3 million Earths to fill up the volume of the Sun. Our Sun is so big it makes up over 99% of the mass of our Solar System.

From 150 million km (93 million mi) away on Earth, the Sun looks small, but it’s really our Solar System’s current powerhouse.

What if we shrunk the Sun down so Earth became the biggest celestial body in our Universe?

Ever feel like the Earth is just too small for the Solar System? Well, let’s make it bigger! Welcome to a new Earth that is just as big as Jupiter. Would the Earth get its own Great Red Spot? How would it interact with other celestial bodies, including Jupiter itself? Would Earth’s growth change the composition of space?

On an Earth of cosmic proportions the size of Jupiter, your body would get heavier with the higher surface gravity. How would you get out of bed if you weighed 11 times your weight? Would Earth attract the planets orbiting the Sun? Take a magical journey through space with us to find out!

What If You Lived on Kepler 22-b?

What If You Lived on Kepler 22-b?



635 light-years from where you are sitting, way out in outer space, lies a planet. The first planet to be discovered inside the habitable zone of a Sun-like star. Its name is Kepler 22-b. When a planet is located within a star’s habitable zone, it means that there is a chance that liquid water exists on its surface. And where there’s water, there’s also the possibility of life. Human life. What would the weather be like over there?

The History Of Astronomy

The History Of Astronomy



Who we are? Where do we come from and where are we going? How and why was the Universe born? These are some of the eternal questions associated with astronomy that continue to pique human imagination from ancient times to the present day. Astronomy is the science that has as its main purpose the determination of the positions, dimensions and movements of the celestial bodies. So in this video we are going to talk about something magnificent that will help us understand the humanity’s perception over the years about astronomy. Let’s analyze and get deep into the history of astronomy.

Astronomy is the oldest of the natural sciences and powerfully associated with religious, cosmological, and astrological beliefs. The first astronomers were the ones who could distinguish the planets and the stars due to the fact that they were the first ones that made observations and predictions.
From the beginning humanity turned its eyes to the sky full of awe and questions. The sunrise and sunset of the Sun, the phases of the Moon, the alternation of seasons, the movement of other planets in the sky, the appearance of comets and the shocking phenomenon of eclipses, were the first evidence that there is something above that needs to be discovered. That is how astronomy started to develop. These incidents raised our curiosity and made us wonder what are they? Where do they come from? We do know today but imagine in those days… they were like Gods.
As early as the 6th century BCE, ancient Greek philosophers documented evidence that Earth was a sphere. They noted that the night sky looked different when seen from various locations on Earth, hinting at our planet’s curved surface. They also observed the round shadow of Earth on the Moon during lunar eclipses. These philosophers were even able to calculate the circumference of Earth quite accurately. They did this by measuring the length of the shadow cast by an object at exactly the same time, in two different locations. Taking into account the distance between those two locations and the difference in the lengths of the shadows, they calculated that Earth’s circumference was about 46,250 kilometres. That is very close to the real value of 40,075 kilometres!
In the year 185, Chinese astronomers became the first to document a supernova. Several supernova explosions have been observed since then, including a particularly bright one in the year 1054, which (at its peak) was four times brighter than planet Venus, one of the brightest objects in the night sky. Some supernovae are even bright enough to be visible during the day!
The notion that our own galaxy – the Milky Way – is but one of trillions of other galaxies in the universe only dates back about a century. Before then, nearby galaxies were thought to be cloudy regions of the Milky Way. The first documented observation of the neighbouring Andromeda Galaxy was in the year 964 by a Persian astronomer who described it as a “nebulous smear.” For centuries, it was simply known in star charts as the “Little Cloud.”
Before the 16th century, Earth was commonly thought to be at the centre of the solar system, with all other celestial objects revolving around it. This is known as the geocentric model. This theory, however, did not match some confusing observations made by astronomers, such as the path of planets that appeared to move backwards on their orbits.
In 1543, Polish astronomer Nicolaus Copernicus proposed a heliocentric model of the solar system in which the planets orbit the Sun. This model explained the unusual path of planets that astronomers had observed. The new theory was one of many revolutionary ideas about astronomy that emerged during the Renaissance period.
The work of astronomers Tycho Brahe and Johannes Kepler led to an accurate description of planetary motions and laid the foundation for Isaac Newton’s theory of gravitation. This progress dramatically improved humanity’s understanding of the universe.

What If Uranus Collided With Earth?

What If Uranus Collided With Earth?



It’s been 30 days since Uranus first appeared in the sky. At first, it looked like our Moon had found itself a stellar partner. But then, we understood something much, much bigger was headed our way. What caused Uranus to become so unstable? How could this epic collision change the ice giant? And what’s with this horrific stink? Ugh.

What If Earth Was the Size of Jupiter? #Shorts



Earth just got an upgrade!

If we made Earth 1,300 times bigger, we could make Earth the size of Jupiter.

A new, super-Earth could be rocky, icy or gaseous. What would happen to your body on an Earth the size of Jupiter?

What If We Nuked the Sun?

What If We Nuked the Sun?



Humanity’s nuclear arsenal is capable of destroying all life on Earth. Over. And over. And over. Maybe it’s time we dumped it far away. We might want to inhabit other planets in the future, so how about our closest star? How many nukes could we throw at the Sun? What would be the price tag for this mission? And could we accidentally destroy our only source of daylight?
