Speed of light and distance

It is a nearly universal maxim of science fiction that faster than light (FTL) travel must exist. Let us take a look at why this is universally necessary for the sake of a good story by comparing the size and scope of both our real universe and a few fictional universes to how long traversalContinue reading “Speed of light and distance” Continue reading

The Universe as the United States

If there’s one straightforward lesson from astronomy, it’s that we’re tiny. We’re small compared to the Earth’s vast size, which is small compared to the sun, which is tiny compared to the space that contains our solar system, which is a tiny dot in one arm of the Milky Way galaxy, which is one of … Continue reading The Universe as the United States Continue reading

The Size of the Universe, Relative to the Size of a Picnicker

The video begins with a man and a woman out on a picnic, then begins zooming out farther and farther. They start with a focus image 1 x 1 meter wide, then zoom out to a field of vision 10 times larger every ten seconds. So, the first zoom out brings the image to 10m … Continue reading The Size of the Universe, Relative to the Size of a Picnicker Continue reading

A Speck on a Speck in a Speck in a Speck…

Humans are very arrogant creatures, and we often forget just how small we are in relation to the rest of the Universe. So much so that our units of measurement are very impractical to use on a larger scale, so we will mostly be using light seconds, minutes, hours, day, months and years to talk about […] Continue reading

The Incredible Scale of the Universe

There’s really no other way to phrase it: the universe is enormous. With our current level of technology, it might as well be an infinite space, but there is a limit to our universe. Our best guess as to the size of the universe right now is that the universe is around 93 billion light … Continue reading The Incredible Scale of the Universe Continue reading

Speck of Dust and Cosmic Sand (Blog #1)

As of the time of writing, Voyager 1 is over 21.1 billion kilometers away from its launch point of Earth. This distance seems long to most, but in the grand scheme of things it is almost nothing at all. This distance represents only 0.2% of that of a lightyear, meaning that a photon released from … Continue reading Speck of Dust and Cosmic Sand (Blog #1) Continue reading

UY Scuti

The size of the Sun is difficult to comprehend. With a diameter of 865,000 miles, The Sun has the volume of 1.3 million Earths. If we were to place the Earth next to the Sun, we would simply see a tiny spec next to the Sun. However, the Sun is not even close to the […] Continue reading

Comprehension

The universe is massive. There are billions of people on this planet. There are billions of planets in our galaxy. There are billions of galaxies in our universe. And this is just in the observable universe, possibly just a small slice of the true universe. But does this really mean anything to people? Does mankind […] Continue reading

Blog #1 Vast Size and Scale

From Chapter 1 of our course textbook, we dived deep into the vastness that is space. We explored what our cosmic address is, how long it takes to travel among the stars in terms of light-years, and measured our distance from the center of the Milky Way. Despite this almost unimaginable expanse, the chapter doesn’t really […] Continue reading

Size and Scale

The Universe is absolutely massive, and it never fails to impress us when there is a new way of seeing how truly large it is. Every time there is a new video or a picture of a tiny dot next to an enormous ball that helps us visualize how enormous the scale of the Universe… Continue reading
