Quick Answer: Can We See To The Edge Of The Universe?

What would you see at the edge of the universe?

It is just spacetime, expanding.

“All the measurements indicate that all of the universe we can see, including the edge of the observable universe, looks approximately like our local universe does today: with stars, galaxies, and clusters of galaxies and lots of empty space.”.

What is on the other side of the edge of the universe?

At the edge of the Universe, Gravity is at it most energy positive value but that is still a negative value. No the Universe does not need anything to expand into. Nothingness is on the other side. Because this is the same condition before the Big Bang and the Big Bang just has not reached there yet.

What is the universe contained in?

It includes living things, planets, stars, galaxies, dust clouds, light, and even time. Before the birth of the Universe, time, space and matter did not exist. The Universe contains billions of galaxies, each containing millions or billions of stars. The space between the stars and galaxies is largely empty.

What is at the end of space?

No, they don’t believe there’s an end to space. However, we can only see a certain volume of all that’s out there. Since the universe is 13.8 billion years old, light from a galaxy more than 13.8 billion light-years away hasn’t had time to reach us yet, so we have no way of knowing such a galaxy exists.

Do things exist when not observed?

An item truly exists only as long as it is observed; otherwise, it is not only meaningless but simply nonexistent. The observer and the observed are one.

Does the past really exist?

The past and future do not exist and are only concepts used to describe the real, isolated, and changing present. This conventional model presents a number of difficult philosophical problems, and seems difficult to reconcile with currently accepted scientific theories such as the theory of relativity.

Who created God?

Defenders of religion have countered that the question is improper: We ask, “If all things have a creator, then who created God?” Actually, only created things have a creator, so it’s improper to lump God with his creation. God has revealed himself to us in the Bible as having always existed.

Does the universe has a beginning?

The usual story of the Universe has a beginning, middle, and an end. It began with the Big Bang 13.8 billion years ago when the Universe was tiny, hot, and dense. … When things finally cooled enough for the first hydrogen atoms to form, the Universe swiftly became transparent.

How long would it take to get to the edge of the universe?

It’s Space Day, but traveling the vast entity that is space would take far longer than a single day. The nearest galaxy: 749,000,000 (that’s 749 million) years. The end of the known universe: 225,000,000,000,000 years (that’s 225 trillion) years.

What is on the other side of a Blackhole?

The event horizon is a proposed boundary around a black hole. On the other side of it, the gravitational pull of the black hole is so strong that, in order to escape it, an object would have to be moving faster than the speed of light, a feat that almost all physicists agree is impossible.

Is time an illusion?

According to theoretical physicist Carlo Rovelli, time is an illusion: our naive perception of its flow doesn’t correspond to physical reality. … He posits that reality is just a complex network of events onto which we project sequences of past, present and future.

Are there other universes?

Together, these universes comprise everything that exists: the entirety of space, time, matter, energy, information, and the physical laws and constants that describe them. The different universes within the multiverse are called “parallel universes”, “other universes”, “alternate universes”, or “many worlds”.

Is our universe infinite?

The universe is unquestionably huge. … The observable universe is still huge, but it has limits. That’s because we know the universe isn’t infinitely old — we know the Big Bang occurred some 13.8 billion years ago. That means that light has had “only” 13.8 billion years to travel.

What’s out there in the universe?

The universe is a vast expanse of space which contains all of everything in existence. The universe contains all of the galaxies, stars, and planets. The exact size of the universe is unknown. Scientists believe the universe is still expanding outward.

Does the universe have an end?

The end result is unknown; a simple estimation would have all the matter and space-time in the universe collapse into a dimensionless singularity back into how the universe started with the Big Bang, but at these scales unknown quantum effects need to be considered (see Quantum gravity).

What is outside the universe?

In our own backyard, the Universe is full of stars. But go more than about 100,000 light years away, and you’ve left the Milky Way behind. Beyond that, there’s a sea of galaxies: perhaps two trillion in total contained in our observable Universe.

Can observing something change it?

While the effects of observation are often negligible, the object still experiences a change. This effect can be found in many domains of physics, but can usually be reduced to insignificance by using different instruments or observation techniques.

Who created the universe?

In his 1988 book, A Brief History of Time, Hawking had seemed to accept the role of God in the creation of the universe. But in the new text, co-written with American physicist Leonard Mlodinow, he said new theories showed a creator is “not necessary”.

How old is our universe?

13.8 billion yearsUniverse is 13.8 billion years old, scientists confirm Scientists estimate the age of the universe by measuring its oldest light.

Is the universe really flat?

The exact shape is still a matter of debate in physical cosmology, but experimental data from various independent sources (WMAP, BOOMERanG, and Planck for example) confirm that the universe is flat with only a 0.4% margin of error.
