Are there places in the universe with no light?

The universe is relatively homogeneous and isotropic. No matter where you go in our observable universe you will have about the same quantity of light from the stars. There are places that are more devoid of matter, but light can travel with almost no dissipation to these places too.

Is dark matter empty space?

Astronomers theorize that the faster expansion rate is due to a mysterious, dark force that is pulling galaxies apart. One explanation for dark energy is that it is a property of space. Albert Einstein was the first person to realize that empty space is not nothing.

What is the oldest thing we can observe in the universe?

Astronomers have found the farthest known source of radio emissions in the universe: a galaxy-swallowing supermassive black hole.

What is the oldest light we can see?

the cosmic microwave background
| In 2013, the Planck space telescope released the most detailed map to date of the cosmic microwave background, the relic radiation from the Big Bang. It was the mission’s first all-sky picture of the oldest light in our universe, imprinted on the sky when it was just 380,000 years old.

Can there be a universe without light?

So the answer is: yes, the universe can exist without light. Although it would most likely just be a giant ball of hydrogen and life wouldn’t be able to exist either. Originally Answered: Can there be a universe without light?

Why are some parts of the universe not visible to US?

Some parts of the universe are too far away for the light emitted since the Big Bang to have had enough time to reach Earth, and so lie outside the observable universe. In the future, light from distant galaxies will have had more time to travel, so additional regions will become observable.

How far can we observe galaxies in the universe?

In a non-expanding Universe, as we covered earlier, the maximum distance we can observe is twice the age of the Universe in light years: 27.6 billion light years. But in the Universe we have today, we’ve already observed galaxies more distant than that!

How far back in time can we see the universe?

Therefore, the longer we wait, the farther we can see, as light travels in a straight line at the speed of light. So after 13.8 billion years, you’d expect to be able to see back almost 13.8 billion light years, subtracting only how long it took stars and galaxies to form after the Big Bang.
