Amazing facts from the world of science.

As you have not stated what these speculative quotes are, please mention them.

Einstein's theory of relativity has been put to the test any number of times, and it has now been described as a perfect theory.
That also goes for quantum theory even if 'nobody understands it' (Richard Feynmann, champion of quantum physics).

I don't think this is entirely accurate. Relativity and quantum physics are not yet compatible with each other - Einstein spent the rest of his life trying to reconcile them.
Also both relativity and quantum physics cannot yet adequately explain dark matter or dark energy (it's why they're still called dark).
Also things like the arrow of time, 2nd law of thermodynamics, why more matter than anti-matter, the finely balance fundamental constants, etc are all open questions.

They may be by far the best explanations we have so far, but they are just one step in a long chain of increased understanding from Aristotle's time. Speculation can be fun but we are miles away from fully understanding. Took 50 years from Higgs boson theory to proving it. We haven't reached perfection yet

Special relativity and quantum mechanics were unified by Paul Dirac (from Bristol) in the early part of the last century.
We don't as yet have a unified theory of general relativity and quantum mechanics, but string theory and quantum loop gravity are being worked on.
-------
Our galaxy appears to be a hybrid.
Billions of years ago an unknown galaxy (Gaia) collided with the Milky Way.
As for the future:
The Large Magellanic Cloud (4th largest galaxy in our local group) is predicted to merge with us in about 2 billion years.
The Andromeda galaxy is predicted to collide with us in 4.5 billion years.
And the Triangulum Galaxy—the third-largest and third-brightest galaxy of the Local Group—will participate in the collision event.

Any observers are only likely to see many more stars in the sky within our merged super galaxy as all 2 trillion+ other galaxies will have disappeared beyond the observable horizon.

If it is unknown, how do you know it's name?

If, in billions of years time, these predictions prove to be false, who's going to care what was posted about it on the GM Forum?

Hmmm. Not necessarily true -and, of course, totally unprovable.

You do seem to post mainly "soundbites" in this thread .....

Ooops. Sorry. Of course it was you who started it....

Just a shame that you have posted so many conflicting "opinions"

Due to the accelerating expansion of space which carries the galaxies with it, about 98% of them are believed to be already beyond our vision.
This is not true of our local group because gravity is strong enough to eventually pull them together.
