What would happen if the Sun were replaced by a 1 solar-mass black hole?
Our Sun is too small a star to end its life as a black hole. But what would happen if the Sun were suddenly replaced with a black hole of the same mass? Contrary to popular belief, the Solar System would not be sucked in: a solar-mass black hole would exert no more gravitational pull than our Sun.
What would happen if a black hole instead of the Sun?
After the sun is replaced by a black hole, the earth, and all the planets will lose their light source. This will lead to various events that end in the extinction of life. Well, the first thing that happens is that the atmosphere on Earth will rain like a liquid and it will freeze.
What would happen if the Sun became a black hole with the same mass as now quizlet?
If our sun were squished to become a black hole, what would happen to the Earth? Nothing, Earth would orbit the sun like usual.
How big would a black hole be with the mass of the sun?
The black hole in GRO J1655-40 is estimated to weigh about 5.4 times the mass of the Sun, which would give it a radius of about 10 miles.
What would happen if a trickster alien replaced the Sun with a black hole of the same mass quizlet?
Because the mass of the black hole is the same as the mass of the Sun there would be no change to the curvature of spacetime at distances far from the object such as at the orbit of Earth.
Will Sun become a white dwarf?
So what will happen to the Sun? In some 6 billion years it will end up as a white dwarf — a small, dense remnant of a star that glows from leftover heat. The process will start about 5 billion years from now when the Sun begins to run out of fuel.

What can destroy a black hole?
Black holes are among the most destructive objects in the universe. Anything that gets too close to a black hole, be it an asteroid, planet, or star, risks being torn apart by its extreme gravitational field. By some accounts, the universe may eventually consist entirely of black holes.
What would happen to the orbits of the Solar System planets if we magically replace the Sun with a black hole of the same mass quizlet?
Nothing—Earth's orbit would remain the same.
Is TON 618 coming to Earth?
2:515:19How Large is the Largest Black Hole – TON 618? – YouTubeYouTube
Is TON 618 bigger than the Milky Way?
In the case of TON 618, the enormous Lyman-alpha nebula surrounding it has the diameter of at least 100 kiloparsecs (320,000 light-years), twice the size of the Milky Way.
What would happen if a trickster alien replaced the sun with a black hole of the same mass?
Our Sun is too small a star to end its life as a black hole. But what would happen if the Sun were suddenly replaced with a black hole of the same mass? Contrary to popular belief, the Solar System would not be sucked in: a solar-mass black hole would exert no more gravitational pull than our Sun.
Can a black hole eat a whole galaxy?
No. There is no way a black hole would eat an entire galaxy. The gravitational reach of supermassive black holes contained in the middle of galaxies is large, but not nearly large enough for eating the whole galaxy.
Will the sun go nova?
Our sun is too small to go nova or supernova. It will ultimately enter a red giant stage and then collapse as a white dwarf. It would need to be at least eight times more massive to nova.
Can the sun turn into a red giant?
A red giant is a dying star in the final stages of stellar evolution. In about five billion years, our own sun will turn into a red giant, expand and engulf the inner planets — possibly even Earth.

Is there a white hole?
White holes cannot exist, since they violate the second law of thermodynamics. General Relativity is time symmetric. It does not know about the second law of thermodynamics, and it does not know about which way cause and effect go.
What is a white black hole?
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.
What would happen if Jupiter was suddenly replaced by a black hole with the same mass as Jupiter?
Imagine what would happen if Jupiter were suddenly replaced by a black hole with the same mass as Jupiter. The orbits of the solar system would be unaffected (including Jupiter's). Which of the following is closest in size (radius) to a neutron star? A city.
How big is the unicorn black hole?
3 solar masses Rare and not well understood, these are cosmic objects that are by no means small to human eyes. The heaviest neutron star that has been found so far is 2.5 solar masses, while the Unicorn is among the smallest known black holes at 3 solar masses. The few that have been detected are all around 5 solar masses.
How big is Milky Way black hole?
The size of a black hole is defined by its event horizon — a distance from the center of the black hole within which nothing can escape. Scientists had previously been able to calculate that Sagittarius A* is 16 million miles (26 million kilometers) in diameter.
Whats the biggest thing in space?
the Hercules-Corona Borealis Great Wall The biggest single entity that scientists have identified in the universe is a supercluster of galaxies called the Hercules-Corona Borealis Great Wall. It's so wide that light takes about 10 billion years to move across the entire structure.
Are wormholes real?
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.
Will 2 stars collide in 2022?
According to study from a team of researchers from Calvin College in Grand Rapids, Michigan, a binary star system that will likely merge and explode in 2022. This is an historic find, since it will allow astronomers to witness a stellar merger and explosion for the first time in history.

What will the Sun run out of in 6.5 billion years?
But in about 5 billion years, the sun will run out of hydrogen. Our star is currently in the most stable phase of its life cycle and has been since the formation of our solar system, about 4.5 billion years ago.
What would happen if we had no gravity for 5 seconds?
Without gravity, the pressure of the Earth's inner core will cause the planet to expand. It's not like five seconds without gravity would cause the world to explode, but even a five-second expansion of the Earth's inner core would cause some major earthquakes, and trigger huge volcanic eruptions.
What if Earth had 2 moons?
The consequences of a second moon orbiting the Earth depend on how massive that moon is and how far from the Earth it orbits. The most obvious effect would be that the ocean tides would be altered. Tides could be either smaller or higher and there could be more than two high tides per day.
What happens if the Earth loses oxygen for 5 seconds?
The ozone layer is made of oxygen. If the world lost its oxygen for five seconds, the earth would be an extremely dangerous place to live in. Due to the severe sunburn, our inner ear would explode. The air pressure on the earth would drop 21 per cent and our ears would not get enough time to settle.
