What is opposite of black hole?
White holes
White holes are theoretical cosmic regions that function in the opposite way to black holes. Just as nothing can escape a black hole, nothing can enter a white hole. White holes were long thought to be a figment of general relativity born from the same equations as their collapsed star brethren, black holes.

the Big Bang
The Big Bang: the birth of the universe
Around 13.7 billion years ago, everything in the entire universe was condensed in an infinitesimally small singularity, a point of infinite denseness and heat. Suddenly, an explosive expansion began, ballooning our universe outwards faster than the speed of light.

What is on the opposite side of a black hole?
So, if you had any plans to travel into a black hole, I urge you to reconsider. This isn't a way to quickly travel to another spot in the Universe, or transcend to a higher form of consciousness. There's nothing on the other side. Just disassembly and death.What does white hole do?
White holes are theoretical cosmic phenomena that function in the opposite way as black holes; instead of attracting matter into an infinitely dense singularity due to immense gravity, it pushes out matter and light, preventing anything from re-entering past its event horizon.Is a white hole a real thing?
A white hole is a bizarre cosmic object which is intensely bright, and from which matter gushes rather than disappears. In other words, it's the exact opposite of a black hole. But unlike black holes, there's no consensus about whether white holes exist, or how they'd be formed.What is a white hole vs black hole?
The simple difference between a white hole and a black hole is that a white hole allows anything inside it to escape back out into space freely, but nothing can get in from the outside, and a black hole allows nothing inside to escape outside, except radiations but pulls everything from the outside in.What Is a White Hole? (Opposite of Black Hole)
Do we live in white holes?
There are no known physical circumstances that can lead to the existence of white holes. They are purely hypothetical (due to the math). Though Smolin says that they actually exist on the other side of black holes.Do wormholes exist?
Wormholes are shortcuts in spacetime, popular with science fiction authors and movie directors. They've never been seen, but according to Einstein's general theory of relativity, they might exist.Can Earth be swallowed by a black hole?
Will Earth be swallowed by a black hole? Absolutely not. While a black hole does have an immense gravitational field, they are only “dangerous” if you get very close to them.What dark matter is not?
Unlike normal matter, dark matter does not interact with the electromagnetic force. This means it does not absorb, reflect or emit light, making it extremely hard to spot. In fact, researchers have been able to infer the existence of dark matter only from the gravitational effect it seems to have on visible matter.Can black holes be portals?
According to a study published in Monthly Notices of the Royal Astronomical Society, a team of researchers seeking to prove the existence of wormholes say they may have found evidence that some known black holes in the universe are entrances to portals that could allow travelers to venture through space-time.What is a wormhole in space?
wormhole, solution of the field equations in German-born physicist Albert Einstein's theory of general relativity that resembles a tunnel between two black holes or other points in space-time. Such a tunnel would provide a shortcut between its end points.What is wormhole theory?
The wormhole theory postulates that a theoretical passage through space-time could create shortcuts for long journeys across the universe. Wormholes are predicted by the theory of general relativity.What would happen if two black holes collide?
It is possible for two black holes to collide. Once they come so close that they cannot escape each other's gravity, they will merge to become one bigger black hole. Such an event would be extremely violent. Even when simulating this event on powerful computers, we cannot fully understand it.What's at the other end of a black hole?
The exact fate of matter sucked into a black hole has long been the subject of debate, but the general view is that it all would be compressed into one point in space—the singularity. A rear exit would provide a place for matter to go instead of being completely smashed.What is on the other side of universe?
The universe is infinite, so it cannot (by definition) expand into anything and there is nothing on the other side.What is the end of black hole?
The singularity at the center of a black hole is the ultimate no man's land: a place where matter is compressed down to an infinitely tiny point, and all conceptions of time and space completely break down. And it doesn't really exist.Does anti matter exist?
For the past 50 years and more, laboratories like CERN have routinely produced antiparticles, and in 1995 CERN became the first laboratory to create anti-atoms artificially. But no one has ever produced antimatter without obtaining the corresponding matter particles also.Are humans matter or energy?
In life, the human body comprises matter and energy. That energy is both electrical (impulses and signals) and chemical (reactions).Can we touch dark matter?
No. Generally, the phrase “touch” implies some surface contact between your skin and a substance. This contact fundamentally relies on electromagnetic interactions in the atoms and molecules in your skin. Since dark matter does not interact electromagnetically, you cannot touch it in the conventional sense.Can humans create a black hole?
To study the phenomenon more closely, physicists in Israel managed to create a lab-grown, analogue black hole using some thousand atoms. This faux black hole exhibited all properties of a black hole in the state in which it is believed to exist in space.Can black hole eat Sun?
The black hole is 1.2 billion light-years away from Earth and 8,000 times bigger than the black hole Sagittarius A*, which is at the centre of the Milky way. The giant black hole is already huge and due its massive size, it can sustain the diet of one sun a day.Can time be bent?
So to answer your question, time does not literally "bend". A massive object modifies the proper time interval around it such that an outside observer would see objects near the mass experience less time and spacetime intervals would have their spatial components modified accordingly.Is time Travelling possible?
Yes, time travel is indeed a real thing. But it's not quite what you've probably seen in the movies. Under certain conditions, it is possible to experience time passing at a different rate than 1 second per second. And there are important reasons why we need to understand this real-world form of time travel.How many universes are there?
In a new study, Stanford physicists Andrei Linde and Vitaly Vanchurin have calculated the number of all possible universes, coming up with an answer of 10^10^16.
