Where does space end?
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..
How old is our universe?
13.8 billion yearsAs astronomer Howard Bond of Pennsylvania State University pointed out, the age of the universe — determined from observations of the cosmic microwave background — is 13.8 billion years old.
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.
What will cause the Big Rip?
Disconzi’s hypothesis is based on existing theories about dark energy, a largely theoretical substance thought to make up 70 percent of the universe’s mass. For a Big Rip to occur, dark energy must win in its battle with gravity to such a point where it can rip apart individual atoms.
How long does it take to get the big rip?
The team found that the earliest a big rip can occur is at 1.2 times the current age of the universe, which works out to be around 2.8 billion years from now.
Who died on the moon?

Could we be in a black hole?
A black hole is an object so dense that not even light can escape it. … Some researchers believe the universe emerged from the collapse of a star in a very different reality with five dimensions, meaning our reality was created by a black hole which we could still be living inside.
Does time have an end?
“Time is unlikely to end in our lifetime, but there is a 50% chance that time will end within the next 3.7 billion years,” they say. That’s not so long! It means that the end of the time is likely to happen within the lifetime of the Earth and the Sun. … At least, not for another 3.7 billion years.
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”.
Will the universe be reborn?
The universe could bounce through its own demise and emerge unscathed. A new “big bounce” model shows how the universe could shrink to a point and grow again, using just the cosmic ingredients we know about now.
What is the Black Hole Era?
The Black Hole Era is defined as “40 < n < 100". In this era, according to the book, organized matter will remain only in the form of black holes. Black holes themselves slowly "evaporate" away the matter contained in them, by the quantum mechanical process of Hawking radiation.
Will the universe eventually die?
The fate of the universe is determined by its density. The preponderance of evidence to date, based on measurements of the rate of expansion and the mass density, favors a universe that will continue to expand indefinitely, resulting in the “Big Freeze” scenario below.
How long would it take for the universe to collapse?
According to the formulas used to calculate cutoffs, a universe that is 13.7 billion years old will reach its cutoff in about 5 billion years, his team concludes. For most people, the idea that a mathematical tool could be elevated to a real-world event might seem strange, but there are precedents for it in physics.
Is Aether dark matter?
Dark matter and dark energy are the opposite: they are concepts that theoretical physicists never wanted, but which are forced on us by the observations. Dark matter, in particular, is nothing at all like the aether. … (Not to mention that it has nothing to do with electromagnetic radiation — it’s dark!)
How cold is space?
Hot things move quickly, cold things very slowly. If atoms come to a complete stop, they are at absolute zero. Space is just above that, at an average temperature of 2.7 Kelvin (about minus 455 degrees Fahrenheit).
Where does space end and heaven begin?
Karman lineSo where does Earth stop and the heavens start? According to a paper that was published in the Journal of Geophysical Research-Space Physics, the border between the two—the so-called Karman line—sits 73.2 miles (188 kilometers) above Earth’s surface.
Will the universe rip itself apart?
Calculations have shown that dark energy could cause the Universe to gradually tear itself apart until there’s nothing left. … Instead of causing a steady expansion of the Universe, the expansion might accelerate over time, causing the Universe to eventually tear itself apart.
How long will universe last?
Assuming that dark energy continues to make the universe expand at an accelerating rate, in about 150 billion years all galaxies outside the Local Supercluster will pass behind the cosmological horizon.
What happens after the big rip?
After the Big Rip Matter is present, but it’s dispersed, as atoms are ripped apart in the final milliseconds before the rip. If acceleration continues, infinitesimal, formless bits of matter could continue to disseminate on an atomic level, with no hope of ever being put back together.
