At the beginning of universe,how many forces were there?1or4?

Question

it is said that universe is expanding and the temperature is increasing.as the temperature increases there is a chance to increase the number of forces.

Answer 1

I had to respond to what Alex wrote, because it's such a load of rubbish. For your information, not one single credible scientist has put forward a credible alternative to the Big Bang theory. Your "no-one knows for sure" remark was a sign of someone who does not have a significant grounding in science, still less physics. Not only is the Big Bang one of the most well corroborated theories in all of science, we are able to determine what happened during the big bang to within the tiniest fraction of a second.

Your claim that "not all scientists believe that the universe is expanding" was the biggest load of nonsense I have heard for a while. The expansion of the universe is a fact, plain and simple. It has been known about since the early part of the twentieth century, although that little point clearly escaped your attention during your science education.

For the questioner, I believe you're referring to the Grand Unified Field Theory. It's believed that all of the forces were unified during the Planck era of the big bang, although we've yet to demonstrate how this came about.

Answer 2

  One,a repeating space-time pulse that forced the universe to expand at the speed of light,the other forces emerged when matter began to form.

Answer 3

when their were all forces then only this world had started.

Answer 4

only one. and there is still only one. it just manifests itself in different ways. some call it god. others call it unified field. i would just say it is somethingness from nothingness, or the lack of nothing. of course tis all just c**p. i just made it up.

Answer 5

One way to understand the concept of an expanding universe is to draw dots, representing galaxies, on a balloon. As the balloon is inflated, each dot moves away from all the others. To a person viewing the universe from a galaxy, all other galaxies would seem to be receding. The distant galaxies appear to be moving away faster than the near ones, which demonstrates Hubble’s law. Most astronomers now believe that this expansion will continue forever.

The big bang theory proposes that the universe was once extremely compact, dense, and hot. Some original event, a cosmic explosion called the big bang, occurred about 13.7 billion years ago, and the universe has since been expanding and cooling.

Answer 6

It is believed that there was only one force originally. As the Universe expanded and cooled, this force underwent a phase transition which caused it to separate into the four known forces today (much like water undergoes phase transitions as it cools from vapor to liquid, then to ice).

The Universe is expanding, but as it does so it continues to decrease in temperature, not increase. If it were to increase in temperature, the four forces would eventually merge back together.

Answer 7

I find this to be an incredibly interesting question... not because of the question itself, but because of the amount of people who seem to think they know exactly what they're talking about while using big words that the average human being would have to grab a dictionary or an encyclopedia in order to make any sense of all the scientific jargon.

I like that everyone mentions some kind of "force" or whatever. I also find it quite amusing and very reassuring that you mention an increase in the temperature of the universe. I can't help but be reminded of a verse of scripture found in 2 Peter 2:12.

It appears to me that the increasing of the universe's temperature is just part of the process of fulfilling this prophecy.

As for your main question concerning the amount of "forces" at the beginning of the universe: the answer is One.  

Answer 8

One theory is that, at some point in time there was one "superforce" that was a combination of all four forces.  One of these forces seperated from this superforce, (I think it was gravity???) and the superforce became unstable.  A fraction of a second later, the rest of the forces seperated, and that was the initiation of the big bang.  

Of course, there is no way to know for sure, and there is as much evidence contrary to this as there is to support it.    

Answer 9

One

Warning ...

  No one really knows for sure.

  Not all scientist believe in the big bang theory and not all believe that universe is expanding.

  If you frame the question like what do most scientist conjecture (guess) about the number of the forces in the beginning of the universe you might get an anwser and the answer is one is you look at various journals and papers.

I quote

"The four physical forces of nature were originally combined. What does this mean, you ask? We all know of at least one of the four forces: gravity. Despite common belief, gravity is the weakest of the forces, yet it is the only one that can act over long distances and stay attractive. The second of these forces is the electromagnetic force. This force holds electrons in their orbit in an atom. Electromagnetic force does not function in the type of distances that gravity does."
