How to yeet yourself out of the fabric of space time and existence, into the particle singularity that our universe began?

You would need a yeet machine.

I think they are on sale at Walmart.

The trouble is people who use them sometimes end up in an alternate universe where there are no planets. So you have to be careful setting the controls.

You could jump into any black hole. You will find a singularity in each one of them. You can't go into the Big Bang singularity since it doesn't exist anymore. It exploded 14 billion years ago.

Light travels and the singular didn't explode on earth so You need to travel faster than the speed of light towards the biggest event horizon which was probably the beginning of the universe. What we see takes time to reach us. That time is dependent on how fast light travel, so you just need to go so faster than it and you are likely to catch the big bang just as it happens or a few second before. I am not sure if you could go before the big bang because i haven't been there. My ben 10 watch ran out of charge so had to come back home quickly.

Go yeet yourself.

I make it a point never to yeet myself.

Meditate, but I doubt if anyone can meditate back to the Big Bang.
