IT WORKED!

I've done it! I've finally done it! The solution was so simple; it was sitting in front of my eyes the entire time. In order to stabilize the wormhole, I shouldn't have reversed the polarity. I simply needed to enclose it in a dark matter chamber. This way, the dark matter chamber can act as a buffer, a sort of astrophysical sponge that absorbs the strong fluctuations in gravitational force. Anyway, all this to say, I finally built a time machine.

I loaded plutonium into the miniature nuclear reactor, fired up the motor, and stood in awe as blue and purple lights began to flash. A small circle formed in the middle of the machine and began to spread outwards until it was about seven feet in diameter. Nervous, I started at the glowing portal, not moving a single muscle. So much could go wrong. If the nuclear reactor failed or ran out of uranium, my tether to the present would be ruptured, meaning I wouldn't be able to reopen the wormhole to go back home. Not only that but if the wormhole isn't calibrated correctly, my body could be stretched like taffy, killing me in a quick, painful death. I could have kept going but negative thinking wasn't going to help anything at that point.

Right foot first, left foot second, I managed to propel myself forwards towards a new frontier: the past. Suddenly, everything got so bright that my vision went black. After what seemed like a few seconds, my eyes were flooded with light again. Once they adjusted, I found myself in a dark alley.

Across the street, I saw a man. "Sir, what year is it?" I asked him.

"1947," he replied, eyeing me strangely.

1947? 1947! It worked! I did it! My adventure through space-time is about to begin.

I walked into a bar, looking for a drink. All around, I only saw Black people, except for one white woman who was sitting with a long-faced Black man. I managed to overhear them talking about some church. Then the white woman made an offhand comment about Mexican "exotics" in California. Overwhelmed, I turned around, walked out the bar, and down the street to buy a room at an inn. That was enough for one day.
