Reality is my god.

Gravity would be different due to different masses. A spaceship that could do that would be like a wet dream for me. But overall, this is not known to be possible. A black hole rips atoms apart. And the physics are universal. But i eould stil love to go there, looknfor life, find things like strong magnetic planets, etc.

Swiss Cheese & Bubble Verses

Imagine a Swiss Cheese - lots of cheesy material with empty bubbles distributed at random inside. Further imagine that the cheesy material goes on forever, so that there is nothing but bubble-filled cheesy material everywhere.

Now imagine that the bubbles contain matter and that the cheesy part is vacuum. This is the current state of the Multiverse - an eternal and infinite Void with little "bubble" universes scattered throughout. Our universe is one such bubble - a "Bubble-verse" (a "Hubble-verse"?).

The edge of the bubble represents the Microwave Horizon, which is expanding into the Void at the speed of light, and is the dying echo of the Big Bang that formed our own little bubble-verse and everything in it.

Other bubble-verses had their own Big Bang events. These Bing Bang events occur spontaneously throughout the Void, each one forming a bubble of matter and energy that expands outward at the speed of light. We may never detect any other bubble-verse because the Void is so enormously large that the light from the nearest neighboring bubble-verse will not reach our location until long after all matter within our own bubble-verse has decayed into a dim quark-like haze.

The estimated age of our bubble-verse is some 13,700,000,000 years, which places the Microwave Horizon some 13.7 billion light-years away. This is the furthest distance that our current technology can detect the most powerful sources of light. Beyond this boundary is the eternal and infinite Void - a cold, dark, and featureless region stretching forever in both time and space.

The laws of Physics has never been observed to be any different on any other planet, in any other stellar system, or in any other galaxy, no matter how far away the observation is made. Therefor, it may be safe to assume that the laws of Physics are constant throughout our bubble-verse, and are likely to be the same in every bubble-verse throughout the Void.

I understand what you folks are saying.

And I understand that scientists spend a great deal of time trying to get to the truth of the matter. And that they believe that the laws of physics on Earth are replicated in other places because of the consistency of the laws.

Still, I would really like to go to other galaxies....for the fun of it, as well as to determine the efficacy of our physics theories in those places. I wonder how local conditions, which are unavailable for us to see from Earth, can affect those laws which they painstakingly determined through many years of research.

Agreed , it would be very fun

Reality is subjective in many ways. But if that is what you worship, knock yourself out. Free World

Delta pretty much commented in flavor of my thought on this

If you believe in a large universe you are putting faith in someone, you haven't seen it yourself so you can't be 100% sure.

Say. What is your take on the "alternate-realities" that are typically called "dreams" ? Subjective-Reality ? Mind-Created Subjectivity ? Brain-Altered Reality ? Subjective-Perceptions ? Other ? I remember once reading from a source that referred to dreams as being a feedback-loop or mental garbage-disposal. Other theories ?

I have always been inspired by the timelessness and universality of physics.

Absolute laws, impossible to break. Everything (known) in the universe follows them.

Why does everything in the universe follow physics?

I don't know, maybe a god made the universe that way. If it was a god, it certainly wasn't the sort of god that would indulge in miracles.

I can't help but think we've actually explored an infinitesimal amount of the Known Universe.
