How do we know the universe is infinite?
If the universe is infinite, it has always been infinite.
At the Big Bang, it was infinitely dense.
Since then it has just been getting less dense as space has expanded.
Imagine a large flat rubber sheet with sand placed as closely together as possible on the sheet..
What is inside a black hole?
The event horizon is where the escape speed exceeds the speed of light: you’d have to be going faster than light (which is impossible for any bit of matter) to escape the black hole’s gravity. Inside the event horizon is where physics goes crazy. … A singularity is what all the matter in a black hole gets crushed into.
Are there other universes?
In fact there are almost too many other potential universes. Physicists have proposed several candidate forms of “multiverse”, each made possible by a different aspect of the laws of physics. The trouble is, virtually by definition we probably cannot ever visit these other universes to confirm that they exist.
Are we living in a black hole?
Poplawski—between two universes. … Call it our mother universe. The seed this mother universe forged inside a black hole may have had its big bounce 13.8 billion years ago, and even though our universe has been rapidly expanding ever since, we could still be hidden behind a black hole’s event horizon.
Does the universe have an edge or a center?
Many of the stars in our galaxy have planets. At the largest scale, galaxies are distributed uniformly and the same in all directions, meaning that the universe has neither an edge nor a center.
What was before the universe?
The initial singularity is a gravitational singularity predicted by general relativity to have existed before the Big Bang and thought to have contained all the energy and spacetime of the Universe.
Does the universe have a center?
Space itself is curved, so as the universe expands from the Big Bang, it is somewhat like the two-dimensional space on a balloon. But just like the surface of that balloon, there is no center in the universe.
What is the universe expanding in to?
The short answer is that this is a nonsense question, the Universe isn’t expanding into anything, it’s just expanding. The definition of the Universe is that it contains everything. If something was outside the Universe, it would also be part of the Universe too.
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.
Is the space infinite?
Newsletter. First, it’s still possible the universe is finite. … 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.
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.
Does space have a smell?
According to astronauts, they all smell like space. While each astronaut smells something a bit different, they all agree ‘space stinks’. Obviously, space is a vacuum, so no one has really ‘smelled’ it before in the traditional sense of the word. … But we can smell it indirectly.
How long would it take to travel to edge of 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.
How many light years is the edge of the universe?
93 billion light yearsThe observable Universe is, of course, much larger. According to current thinking it is about 93 billion light years in diameter.
Does the universe repeat itself?
Unsourced material may be challenged and removed. Eternal return (also known as eternal recurrence) is a concept that the universe and all existence and energy has been recurring, and will continue to recur, in a self-similar form an infinite number of times across infinite time or space.
Who is the creator of universe?
In Hinduism, Lord Brahma is the creator of the universe.
What is beyond the observable universe?
A lot more universe exists beyond what we are able to observe. … According to the theory of cosmic inflation, the entire universe’s size is at least 10^23 times larger than the size of the observable universe. Ultra Deep Field via Hubble/NASA. That’s a lot of universe that we are missing.
Can you travel to the edge of the universe?
Unfortunately, since universe is technically expanding faster than the speed of light (due to the expansion of space between matter), it is theoretically impossible to ever reach the “edge” of the universe, since it will always be moving away faster than we could ever move towards it!
Does the universe have an end?
As the energy density, scale factor and expansion rate become infinite the universe ends as what is effectively a singularity.
Do wormholes exist?
A wormhole is a tunnel-like connection through space-time, much like the real tunnels bored by worms in a (Newtonian) apple. At present, space-time wormholes are only theoretical constructs derived from general relativity; there is no experimental evidence for their existence.
Will the universe last forever?
As long as the amount of stuff doesn’t go over a critical threshold, the universe will continue to expand forever, and eventually suffer heat death, freezing out. But if there’s too much stuff, the expansion of the universe will slow down and stop. Then the universe will begin to contract.
