Hi. why does bitcoin have a vulnerability in time? why is the algorithm not perfect?

why the number of nons that miners are looking for is limited in size? these parameters can expose bitcoin to a huge fork. what i mean. a small miner can mine bitcoin for example have 1-10% of the network from 4-40 exasheh of the entire network.

and when a block is found, not to send it to the network, and hold the solution of a new block for a while, and the new solved hash should be used to find a new block. for example, to find a block and leave the ready answer for 10 seconds and start looking for a new block, say, mine for the future. and after finding the first one to send then the second, with a difference of 9 seconds. and it does not contradict the rules. but you can go longer and divide miners to search each non separately. that is, 1 miner looking for this number in the range from 0-1000 second from 1001-2000 third 2001-3000 and so on it's a matter of luck)

Of course the solution is to shift the time in the algorithm. it will remove this glitch or bug, or whatever it is called ...
