Scientists have come up with three possible fates for the Universe depending on its mass as it continues to grow. If the Universe is not dense enough to utilize gravity, it will keep expanding forever. This is called an open universe. If the density is just right, the universe will continue expanding but will slow down and ultimately stop completely. This is called a flat Universe.
The clumps were gravitationally pulled towards other clumps and eventually formed galaxies. It is extremely difficult to mode... ... middle of paper ... ...suming that the Universe is all the same. One can also calculate the density required such that the Universe will eventually stop expanding. That density is called the critical density, and the ratio of the observed density to the critical density is given by the Greek letter omega. If omega is less than one the Universe will continue expanding until it is so large that it dies a cold death.
The Kerr black hole, which is the most common form, rotates because the star from which it was formed was rotating. When the rotating star collapses, the core continues to rotate, and this carried over to the black hole. The Kerr black hole... ... middle of paper ... ... succeed, what are the consequences of such freedom? Will we get trapped in a plethora of paradoxes and multiple universes that will destroy the fabric of the universe? Einstein said that nothing travels faster than the speed of light, but Khalili negates this statement, using the behavior of entangled particles to counter Einstein.
One possible horribly catastrophic scenario would be the unforeseen generation of a miniature black hole somewhere on Earth. If the hole did not evaporate instantaneously (and it would have to be pretty large not to, so I don't know how it would be possible to generate one accidentally) it would quickly bore a hole to the center of the Earth, absorbing more and more mass as it went, and eventually implode the planet.
This means that the universe is separating more rapidly than it used to. From this face, there are two theories of the universe’s end; the big chill and the big rip. The Big Chill is a theory that states that the universe will slowly drift apart until all of the stars die out and the planets all freeze and heat disappears. The Big Rip is an even more bleak theory. It states that the universe will expand faster and faster, due to dark energy, until galaxies rip themselves apart.
I don't know what the future holds but I know who holds the future. Days go by and how time flies, seasons always changing. When we contemplate the future we envision mind-warping technology and global warming destroying the Earth. Change is inevitable but it's up to our supremacy what we and our planet Earth change into. Will we help or hinder our future survival?
And it seems that the Olbers paradox would be resolved, but there is a point to clarify. Even before the existence of matter, the high temperature would have to 'burn ' emitting a light that today we see totally black. The answer to this last question is the expansion of the universe. According to this theory the subject moves away from us, which makes the light that comes to us has become a long wavelength. This means that our eyes can not see, but which can be detected by other physical instruments that identify it as the famous cosmic background
As time went on, there were a few main contributors that solved these equations to help develop better theories on black holes.

There is another theory that the supermassive black hole at the center of our galaxy could swallow the Sun, which could result in a drastic and possible deadly effect on the orbits of the planets in our solar system (Wethington). Black holes have been one of the most difficult challenges for astronomers and scientist for many years. I think with new technology that astronomers will be able to gather more information that can offer more insight into the world of black holes.
A Tale of Two Theories Since the dawn of man, humans expressed themselves through legends and myths, advanced throughout the ages. Now, with increasingly advanced scientific equipment we can see that the universe is far more vast and complex than our wildest dreams could have imagined. I hope in writing this, I can shed some light, regarding some modern beliefs regarding the origin of the universe by answering a series of questions. Regarding some of the common theories that may explain the evolution of the universe. What exactly is the "Big Bang Theory" and how does it work?
In A Brief History of Time by Stephen Hawking There were very many interesting theories and facts that were brought up about physics. A couple of these theories and fact help lead me to deciding on my opinion about the future of physics in the 21st century. My opinion is that in the 21st century a couple of things will happen in the way of physics. First I think scientist will continue work on old experiments and make new theories. Another one of my thought are that scientist will prove previous theories wrong.
