Observable Universe Quotes

Dark energy is incredibly strange, but actually it makes sense to me that it went unnoticed, because dark energy has no effect on daily life, or even inside our solar system.

How can a speck of a universe be physically identical to the great expanse we view in the heavens above?

What was after the universe? Nothing. But was there anything round the universe to show where it stopped before the nothing place began?

I can feel the universe expanding and making things be further apart.

We are 13.7 billion light-years from the edge of the observable universe, That's a good estimate with well-defined error bars, Scientists say it's true, but acknowledge that it may be refined, And with the available information, I predict that I will always be with you.

Astronomers say the universe is finite, which is a comforting thought for those people who can't remember where they leave things.

We have a remarkably complete picture in many ways - and it could be that we're not accounting for something that's almost three-quarters of the entire universe.

The universe is expanding, and every second that you're alive, the universe is bigger than it was a second before. There's nothing in front of us, exactly, other than the future, and there's no space for the size, the density of the universe to go. Because it's expanding at every point simultaneously.

If our local, observable universe is embedded in a larger structure, a multiverse, then there's other places in this larger structure that have denizens in them that call their local environs the universe. And conditions in those other places could be very different. Or they could be pretty similar to what we have here.

I'm baffled all the time. We don't know what's driving 96% of the universe. Everybody you know and love and heard of and think about and see in the night sky through a telescope: four percent of the universe.

One of the great challenges of modern cosmology is to discover what the geometry of the universe really is.

There are at least as many galaxies in our observable universe as there are stars in our galaxy.

Astronomers still can't decide what the shape of our universe is. Is it closed and finite, which is to say, is there a countable tally of all the galaxies that exist, even beyond the ones we can see? Or is it infinite? The latter possibility is still on the table.

It was only about sixty years ago that the expansion of the universe was first observed.

A million million million million (1 with twenty-four zeros after it) miles, the size of the observable universe.

If the universe is everything, and scientists say that the universe is expanding, what is it expanding into?

Without science, everything is a miracle.

It is within science itself, and not in some prior philosophy, that reality is to be identified and described.

With increasing distance, our knowledge fades, and fades rapidly. Eventually, we reach the dim boundary-the utmost limits of our telescopes. There, we measure shadows, and we search among ghostly errors of measurement for landmarks that are scarcely more substantial. The search will continue. Not until the empirical resources are exhausted, need we pass on to the dreamy realms of speculation.

We scientists have an obsession with unification, a grand synthesis. And dark matter is an irritating missing piece.

I don't know why anyone would want to study the expansion of the universe.

What we see of the universe is vast. We know that the universe is something like 90 billion light-years across.

We live inside our universe and cannot get a bird's-eye view of it from outside. And we cannot even see all of our universe. Distant parts of it are expanding away from us so fast that they are invisible; they go faster than the speed of light. Having bigger telescopes to see fainter stars will not help us here: invisible is truly invisible.

In 5 billion years, the expansion of the universe will have progressed to the point where all other galaxies will have receded beyond detection. Indeed, they will be receding faster than the speed of light, so detection will be impossible. Future civilizations will discover science and all its laws, and never know about other galaxies or the cosmic background radiation. They will inevitably come to the wrong conclusion about the universe......We live in a special time, the only time, where we can observationally verify that we live in a special time.

The world in which we live is the only world about which our senses can testify.
