Last week we covered multiple star systems, but what if we added thousands or even millions of stars to the mix? A star cluster. There are different kinds of clusters, though. Open clusters contain hundreds or thousands of stars held together by gravity. They-re young, and evaporate over time, their stars let loose to roam space freely. Globular clusters, on the other hand, are larger, have hundreds of thousands of stars, and are more spherical. They-re very old, a significant fraction of the age of the Universe itself, and that means their stars have less heavy elements in them, are redder, and probably don-t have planets (though we-re not really sure.

THE NEW SUPER LAWS OF PHYSICS/PHYSICAL EXPERIENCE:
GRAVITATIONAL force/energy is proportional to (or BALANCED with/as) inertia/INERTIAL RESISTANCE, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. This is proven by F=ma AND E=mc2. Gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. (This is proven by F=ma AND E=mc2) -Mass-/energy IS gravity. ELECTROMAGNETISM/ENERGY IS GRAVITY. -Mass-/energy involves BALANCED inertia/INERTIAL RESISTANCE consistent WITH/AS what is BALANCED ELECTROMAGNETIC/GRAVITATIONAL FORCE/ENERGY, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE, AS GRAVITY IS ELECTROMAGNETISM/ENERGY.
ACCORDINGLY, a given planet sweeps out equal areas in equal times; AND this is THEN consistent WITH F=ma, E=mc2, AND what is perpetual motion; AS ELECTROMAGNETISM/ENERGY IS GRAVITY.
VERY IMPORTANTLY, outer -space- involves full inertia; AND it is fully invisible AND black.

Of interest to me is their gravitational point mass center. The point in space in which all of the stars orbit around. This point may change according to the distance of each stars mass and distance from it but their is a common point that the total mass orbits around. My question is what is contained at that point mass center. It would appear that nothing could exist as a mass at that point in space because the gravitational attraction of all of the masses would be tugging on that point equally. This is the proverbial black hole (void) or in the present scientific theory a black hole mass. At the center of each galaxy their is a point mass center of all of the stars composing the galaxy and the gravitational attractive force is so strong that no mass, not even a photon mass, can exist in and at the point.

As an Angel. I've always come to these star clusters. Planets do exist there but are often rare and ejection does happen on a common basis. It's nearly impossible for them to maintain a stable orbit. I have found some that did evolve plant life despite them being only around 5 million years old, they were flung by their star but their warm atmosphere and it's bright illuminated sky allowed them to grow.

Would that anyone could understand the basic meaning of this universe. I mean that all this universe came into being without of nothing or out of something and if so then how the first thing came into being and why. Pease anyone give me a rational and understandable answer. Thanks in advance.

stars have varying lifespans bro. you can't assume a star is going to be old because it's blue. some high chemical reactions are faster than others. it would undoubtedly depend on what the primary composition of the star is.

Bet that there are a few gas giant planets in globular clusters but I'd imagine that they are a little different then the gas giants in our solar system and in other solar systems that are more metal rich.

Thank you so much for this. Reason why I opened this? Job 38: 31; Job 9: 9 mentioned Bear, Orion, Pleiades! And I-m into tears realizing how beautiful the creations are & above all how great the CREATOR is!

7: 10 It's hard to believe something that full of light and energy, that even looks like a city shining in the dark, isn't alive somehow.
reply

So wait. then what is the difference between a cluster and galaxy? I see that clusters are not spirals but similar to irregulars.
reply

If globular clusters last billions of years, what prevents them ejecting stars from close encounters, like open clusters do?
