Could life forms such as ours, sentient beings, survive if laws of physics were variable?

Only "nothing" has no center.

The physical universe does have a singular beginning which by definition is its center, regardless if is the center of a 2D expanding plane or the center of a 3D expanding sphere.
No. Please, do some reading before making claims about concepts that are easily learnable. This particular one is cosmology 101.

In fact it's not Cosmology 101; it's Google 101: Google Does the universe have a centre.

(And lets not spend the next 12 pages with you doubling down on what you "really meant - in a manner of speaking".)

And another thread is now full of Write4U's derailing rubbish.............
Time to close it, perhaps.

Ok, you want to tackle this?

I am waiting with bated breath. Well....no.. on second thought, I doubt if you have anything interesting to say at all.
 
Well, you make it rather a "how long is a piece of string?" question.

The basic point I think is that for life, varying physics would make chemistry itself doubtful and evolution practically impossible. And that is aside from the issue of whether stars would form and remain intact long enough to provide conditions amenable to life.

So if you make it a condition that gravitation and the speed of light are variable AND that there are nonetheless sentient beings, then you're on your own.
I guess that was a definitive statement. We should have closed the thread at this point.
 
Stating the obvious it would depend on which laws and by how much. I'm going to lay out a speculation for consideration

I'm going to pick

1/ Speed of light = 1,000,000,000 km per hour
Have fun by varying speed by half or doubling

2/ Mass or, perhaps more importantly, the effect of mass ie the amount of mass (number of atoms remains same) but effect of the mass halves or doubles

The sentient beings have no explanation for the variations of their physics since there is no linkage between the variations and no pattern in the appearance of the variations

What effects might (could) be expected with such variations?

Happy to answer any questions but like to hear other persons thoughts

Physics forms , life grows into forms , we seem independent of physics and even though I can explain physics , we are a mystery .

We certainly are not independent of physics. All processes of our body chemistry and physics obey the laws of physics

My question was more intended to explore the idea of not us being able to exist but within a totally different Universe where such a situation (variable laws of physics) exist sentient life arose how would the scientists deal with the challenge?

Would they try to tame physics to be consistent?

Work out the optimum response for each period each aspect of physics they experienced?

Are you sure because a stone can't move as we do because the stone has too obey gravity and inertia . I have no problem personally dude ignoring inertia and moving about , totally defying the laws of physics . I mean dude I can throw a stone but the stone can't throw me , how can even consider pal that we are anything like physics ?

Do you walk. Did you know that walking is a controlled falling forward with every step you take? How much do you weigh? Your weight is gravity acting on the mass of your body. If you are going to talk science, at least verify what you are saying against scientific articles on the internet. That is what I do.

What is weight?
The weight of an object is defined as the force of gravity on the object and may be calculated as the mass times the acceleration of gravity, w = mg. Since the weight is a force, its SI unit is the newton.

What are the mechanics of walking.

It is a controlled act of falling forward.

I sit here a lot talking science

The statement

I have no problem personally dude ignoring inertia and moving about , totally defying the laws of physics

shows you have no idea about physics, I have made bold the most relevant text. What ever you imagined you were posting

I have no problem personally dude ignoring inertia and moving about , totally defying the laws of physics

is not science

I missed the statement below because it was in another post,

I mean dude I can throw a stone but the stone can't throw me , how can even consider pal that we are anything like physics ?

but it confirms my assessment, that of your lack of knowledge with regards to physics

:)

Physics is science !

The mass of the stone is attracted to the mass of the earth and vice versus , a 1kg stone is actually only 0.5kg .

My magnitude of applied force can displace the mass of the stone , F=ma .

Details are boring .
