It looks like you started researching your way onto the Mirror World of the Battlefield. As ar as I know you can't stop the research process if you have only one Squad (i was able to stop it with my second squad but not when i only had one active).
You need to check each of your squad's pets' pages and check their value for "Research Potential". Add the research potential of all 4 pets together, that is the value added hourly to your current 1483/5000. That way you can estimte how much longer you will be stuck there.
For the future, you can influence your pets' research potential by doing certain things - hover the mouse over the question mark next to Research Potential on their profile and click the Details link in the window that pops up. This also gives you a breakdown why a pet has as many research points as it does.
