A lot of scientists believe that a big explosion created the universe. You can't have a explosion from nothing. apparently before the big bang everything was a size of a dot and close together and a explosion expanded the galaxy but how and where did the dot come from?
It is so hard to wrap your mind around a theory that at some point of time noting existed. Can you imagine nothingness?
I'm pretty sure the Big Bang is no longer a theory. Further, it does not actually say our Universe is the first. What was before all universes existed? Good luck answering that.
The universe was never created. It has always been there. It has always existed, and always will exist.
but how can you say "always"? Everything has a beginning. Everything in our planet has a begining and as far as I know everything in our universe has a beginning but why doesn't the universe its self has one??????
it does. see recent research findings. but, the theory now is our universe is not the only one, nor the first. So, you might have to reevaluate your definition of "Universe.' Remember when scientists used to think our solar system was the only one. Appears that's true with our universe thinking, too.
i'm sure there are things and concepts out there we can't even perceive yet. just because you can't imagine it doesn't mean it isn't out there or isn't possible
Shouldn't this be in the debate section? This is going to get in to religious and scientifical territory.
At one point, it was hard to wrap your mind around the idea that we are all made up of atoms, and that actually, most thing is just a vast space of nothing, atoms made up of mostly space. Just because the idea of nothingness is hard to grasp, does not mean it's not there (or not there...haha).
When you say "has a beginning", what do you really mean? With regard to "things" within the universe, it simply means that it was formed, through natural forces, from some other things. It wouldn't make sense to say that the Universe (that is, the totality of all physical existence) had a beginning in this sense. Clearly, the Universe is of a different category from its constituent parts.
It's a never ending cycle of the balancing act between electrical forces and gravitational forces. The universe birthed from the death of the previous universe that collapsed in on itself to a point (gravitational forces + electrical attractive forces >> electrical repulsive forces), then exploding (electrical repulsive forces >> gravitational + electrical attractive forces). The collapse and explosion process take about 8,600,000,000 years together. This cycle lasts for about 311,040,000,000,000 years.
Multiverse baby! It'd be cool to know the answer to all that stuff... Though the answer itselfninsuspect would change little. What we learn along the way should be very transformative though.
