![]() ![]() But our Universe isn’t static it constantly expands, which means that most matter in the Universe has already escaped the clutches of the black hole and will never return to it. ![]() Say the Universe was static black holes could never consume all the matter within it. But, in the vastness of space, that’s nothing. Even the biggest black hole imaginable – let’s say a trillion solar masses – would be limited to a radius of a light year or two. When you consider the sheer size of the Universe, you can understand that most matter will always escape the clutches of a black hole. Take a stellar-mass black hole it could have an event horizon of just a few kilometers, which means that anything traveling more than a few kilometers away from it can easily escape its grasp. What Would Happen If A Black Hole Consumed Everything?Ī black hole will never consume the Universe because they aren’t big enough to capture enough matter. It defines the boundary between what can be seen and what can’t be seen, and it’s also the surface where gravity becomes infinite. The event horizon is an essential concept in general relativity. Still, planet Earth would continue its stable orbit around the black hole and would not be “sucked in.” This is because the Earth is 93 million miles from the Sun, but it would only be sucked into the equivalent black hole if it traveled as close as 10 miles. We would suffer from a permanent state of darkness, and the lack of heat and life would mean that all life died. Say, for example, our Sun was replaced with a black hole. The event horizon of a black hole defines the boundary around a black hole within which matter is so densely packed that light cannot escape. The more massive the black hole, the stronger its gravitational pull will be.īlack holes are not pulling objects towards them they can only capture material that travels very close. Black holes come in different sizes, and their mass is measured in solar masses. Do All Black Holes Pull Objects Towards Them?īlack holes are objects that have such a strong gravitational pull that not even light can escape them. Still, the idea that they suck everything around them is a myth material needs to be traveling close enough to the black hole to cross its event horizon for the black hole to capture it. Supermassive black holes have masses that range from 100 million to 10 billion times the mass of our Sun, while stellar-mass black holes have masses that range from three to ten solar masses.īlack holes are the most powerful gravitational forces in the Universe, so it is no surprise that they consume anything in their path. ![]() There are two types of black holes: supermassive and stellar-mass black holes. The amount of mass a black hole has determines its size. The closer they get to it, the stronger its gravitational pull becomes until it gets so strong that nothing can escape from its force. This force pulls all the atoms and molecules toward it. The reason why black holes suck everything is because they have such a powerful gravitational force. They form when a star dies and is crushed into an extremely dense object here, gravity becomes so intense that not even photons can escape its grasp.

"If a black hole's event horizon gets bigger every time its density gets bigger, i.e., it "absorbs" mass, why hasn't the whole universe collapsed into an enormous black hole yet? Shouldn't this kind of expanding black hole be getting bigger exponentially? And will this be the end of our universe and possibly the birth of a new one (or where ours began-a big bang)?"-Shaido666 So.what is the speed limit measured against?"-l ordv27 "If all movement is relative, how can there be a speed limit? In order to measure speed, you have to measure it against something. Would I see the dinosaurs moving faster-fast-forwarded?"-sl270703 If my ship started travelling towards earth near the speed of light. Using a telescope, I look at Earth and I see dinosaurs living their daily lives. "Let's say I'm an alien on a ship 65 million or more light-years away. ![]()
