How can Scientists be sure that Black Holes exist when you can't see them?
The readings that we get from the black holes influence on other matter (stars, entire galaxies in some cases) are the most telling signs that they exist. Black holes have so much mass and therefore so much gravitational pull that they actually bend light around them indicating a "void" of light. A black dot in space completely devoid of light. There are other ways to tell as well, stars in orbits that are gravitationally drawn to a certain area of space-time for no apparent reason. ie there is nothing there. Nothing, but a super-dense ball of matter that we can not see.
black holes are invisible because its gravitational pull is so strong even light cant escape from it. so what scientists do is they look at things around the black hole. if there is a black hold near a planet or star that objects orbit will be altered and it will be heating up from the friction of going into the hole.
Could black holes actually not be holes and just be matter like a star or planet but so dense even light cant escape their gravity?
Black holes fascinate me by there huge size on great gravitational force. The fact that light can't even get out so we cant study the center much is also pretty amazing. The thing that disturbed many astrophysicists when black holes were first theorized was the fact that the theory predicted an object that would destroy the theory that predicted it.
Black Holes are often made during the end of a star,often during a supernova.When they 'die' the star collapses into a single point which is so dense that even light cant escape.Black holes are made up two parts, the singularity and the event horizon. The singularity is the black part, the vacuum. The event horizon is the sphere that covers the singularity, then it acts as a boundary for the black hole.
Im not sure that anyone has yet discovered a real wormhole in space but scientists seem to think that if they do exist they must be similar to a black hole which has such a huge amount of gravity that even light cant escape from it. that being said, a wormhole would not lead you anywhere because you would be crushed by its gravity. Other scientists seem to think that wormholes do exist and they…
there is still no proper answer about the structure of a black hole,as because a black hole cant be seen.But according to assumptions the black hole spins around and thus its structure may be oval or spherical.Like anything thaat rotates, the black holes becomes flatter at the poles and broader at he equator
