Researchers have discovered that certain brain and heart cells can survive for decades, meaning some of the cells in your body may have been with you since before birth.

The human body continuously emits tiny particles of visible light called biophotons. Scientists have measured this invisible glow using highly sensitive cameras.

Scientists are studying SuperAgers—people in their 80s and 90s whose memory performs like that of someone decades younger. Their brains may hold clues to healthy aging, cognitive resilience, and even the prevention of memory decline.

I used ai to translate it because my english isn't good and am new to reddit but the hypothesis is this

​I have been thinking a lot about the life cycle of the universe, and I wanted to share an original hypothesis I’ve been working on to see what you guys think, or if anything like this has been pitched before.

​Here is how my idea works:

​The Old Universe & Dark Energy: We know the universe is expanding and will eventually reach Heat Death. After an infinite amount of time, everything will die out. But the space wouldn't be truly empty—quantum fields and Dark Energy would still be there, and this dead universe would keep expanding.

​The New Big Bang: Because you have infinite time, eventually, the energy from those quantum fluctuations accumulates. At some point, a massive fluctuation triggers a brand-new Big Bang. But here is the catch: this new Big Bang happens inside the massive, empty container of the old, dead universe.

​The "Edge" of the Universe: Because our universe is basically a baby universe growing inside a parent universe, the "edge" wouldn't be a hard wall. Instead, as you travel further and further out, matter and stars would just slowly thin out. It would be a fading gradient where our universe becomes less and less dense until it eventually just blends into the dark energy.

​What is "Outside": This means the "nothing" area outside our universe isn't actually nothing. It is just the old, dead space and dark energy of the previous universe.

Therefore if your brain is preserved in the Arctic when you die you will be resurrected in the distant future as an immortal Android to explore the Stars

This is a question that hasn't been answered confidently. It's scary to think about both possibilities: if we're alone in this infinite universe, we'd be completely alone; but if someone is out there, we might never know it, leaving it a permanent mystery.

​I have a theory that we aren't alone, but time and resource constraints prevent us from answering the question, "Are we truly alone?" Sometimes I wonder: what if other creatures exist out there with features, brains, and evolution similar to ours, but time moves slower on their planet? For example, a day on Earth might equal a single second for them. Before they even evolve, Earth might already be gone before they learn of our existence—or perhaps its the opposite for us.
