The universe is expanding but I'm not too sure about the second part. The obvious thing is that a black hole looks like a big black hole.
Even though black holes suck through parts of the universe, the universe is inevitably big, and growing so as the universe is being sucked into another dimension by black holes, it is also expanding.
No.
Expanding black holes don't mean the end of the universe. It is true that we don't know enough about the universe to be able to see an "end" in sight. But right now the universe is expanding, and the immense gravity of even black holes (and other matter) doesn't seem to be slowing it up at all.
The universe is always expanding - there could be millions a day.
No one knows for sure. There are theories, but absolutely none of them can be proved, and I doubt we will ever find out. The universe is expanding firther into what was here before the big bang. Basically, nothing. The universe isn't expanding like a balloon blowing up; the universe is already there, but the objects inside it are spreading out constantly (black holes, stars, galaxies, etc.) The universe isn't expanding; the objects inside are spreading out within it.
The concept of time being warped and space being bendable, as described by Einstein's theory of relativity, challenges our traditional understanding of the universe. It suggests that time and space are interconnected and can be influenced by gravity and motion. This idea has led to new insights into the nature of the universe, such as black holes and the expanding universe. It also raises questions about the fundamental nature of reality and how we perceive the world around us.
The big bang theory is the explosion that started the universe. Where as the big crunch is the theory where the universe will eventually contract and become increasingly clumped and eventaully all mater would collapse into black holes which would then coalesce producing a unified black hole or Big Crunch singularity.
The Universe appears to be dark because space (meaning nothing), contains no matter for the sun to shine on. Also, another reason is that the universe is so large that, if you were to even try to look at the edge of the universe from outer space, the light would not exist beyond a certain point (because of the measurement of lightyears, and the never ending radius of the universe that is expanding). Thus, the universe is black.
If time were to go on infinitely, the universe were to stop expanding, and the universe didn't collapse on itself or tear apart, (a lot of prerequisites, I know) then, theoretically, yes.
My theory is that the universe was created by the opposite of a black hole. A white hole if you will. That would mean that the universe, instead of being pulled in like a black hole, it would be pushed out. That explains the universe moving away from us. Scientists, you may be wondering how it would hold itself together? Well it wont. And it would rip a big circle in the center of the universe, therefore making the universe bagle shaped as steven hawking thinks. So it is foolproof. At the moment.
simply,the difference is that earth is a planet in the solar system and the universe is the entire infinite space containing the solar system,stars, asteroids ,black holes and all that space has to offer.
There have indeed been some speculations that this may be the case. However, for now it is impossible to verify this. =========================== According to hyper sphere theory it suggest so i.e. the universe is like the event horizon of another universe from a 4 D universe's black hole. This model of the universe helps answers why the temperature of the entire universe is not uniform. According to Big Bang theory the temperature of the universe should have had been evenly distributed by now but this is not the case. A Canadian team of scientists proposed this theory that our universe might in fact be a the membrane of black hole in a 4th dimensional universe. Computer models show that the the 3 D membrane(our universe) surrounding the black hole is expanding. Like there are 2 D event horizons along the 3 D black holes we are the 3 D event horizon around a 4 D black hole called a hyper sphere.
