What happens in the universe in one second?

Although a second may seem insignificant to you, a lot happens in the universe in that small amount of time.

The universe is full of secrets and it is so big that we cannot imagine what its limits are. The more we explore the universe, the more we realize how little we know about it.

Yet despite its many mysteries, humanity has made great strides in understanding the cosmos. In the last few decades, scientists have discovered that there are about 40 billion black holes in the universe. To date, astronomers have discovered more than 5,000 exoplanets in our galaxy that are capable of supporting biological life.

Although we have come a long way, we still cannot answer many mysteries. What is dark matter and what does it represent? Are black holes tunnels through time or space? And much more.

But here are some more impressive facts about the universe.

For us, a second passes in the blink of an eye, but on a cosmic scale, a second is a lot. Lots of things happen in just a second:

For example, in just one second, the Sun will absorb about 1,000,000,000 tons of hydrogen.

In a second, somewhere in the distant universe, a huge black hole is born.

Around 4800 stars will be born and 100 stars will die.

The light will travel almost 300,000 km, or 299,729 to be exact.

In one second, the universe will expand another 2,109,000 kilometers.

In just one second, our galaxy will rotate at a speed of 210 kilometers per second. In addition, it will increase by 500 meters in one second.

Our neighbor in space, the Andromeda galaxy, will come closer to us by 300 kilometers.

Yes, even things happen around us that we can’t see. At this moment, even if you are sitting without blinking, you are moving. We are on a celestial body floating in the dark in the middle of something we know very little about.

If you’re into all things space and want to learn a bit about the things that happen every second, check out the video below. While the numbers it contains are approximate, they put a lot into perspective. A second is a lot longer than most stop to realize, let that settle.
