When scientist research the same problem they often find and publish different results?

Scientists do often research the same issue, but many times, the scientists that are researching the same topic work at the same facility, organization, and/or company. If different scientists are working together, then they will come to a conclusion together and write the results based on their experimentation. If for example two scientists are NOT working together, then they may write different lab conclusions. Here is the important catch: Many scientists are not allowed to publish due to inaccuracy or uncommon theories. The Big Bang Theory is published because many people believe the theory is accurate. Most theories or results are never published. Only written into lab journals. I WOULD GLADLY APPRECIATE IF YOU WOULD NOT PLAGIARIZE. YOU MAY USE MY WordS, BUT UNDER NO CIRCUMSTANCES COPY WHAT I HAVE WRITTEN. THANKS!! :)
