Ordinary Joe needs help from mathematician to prove/ disprove theory
Spacetime curves due to mass and energy, but it doesn't have to do so gently. Consider tossing a baseball on the Earth's surface, or what happens to spacetime too near a black hole. That curvature of spacetime is what we perceive as gravity. Three spatial dimensions and a temporal one is the continuum we call spacetime. It's a coordinate system we can use to plot when and where in the universe an event happens. Matter has mass, mass curves spacetime. But the dimensions would still be there without the matter, so it's not a natural extension of them. There isn't a way anybody could possibly know anything about a time before the Big Bang. Our best maths fizzle out before we can get all the way back to t=0, where the heat and densities destroy any information we might be able to get. A model is the maths a theory is based on. Do you have a model, or want help with a model? You may have some gaps in your science you've filled in with popular misconceptions. It happens a lot when smart people get hold of parts of the puzzle, become hooked, and then make up the rest. I'm sure it makes perfect sense to you, now you have to explain it so peers can understand it.

Removing odour from TPR ?
PG should act as a solvent for whatever volatiles are causing that bad rubber odor, so PG by itself should remove it (a scented product with PG would probably remove AND supplant the scent). You should be able to use any sort of cleaning product with a neutral pH (no ammonia, no vinegar).

Barriers to equal opportunity in education
! Moderator Note Vague generalizations disguised as slurs towards a group of people are against our rules. This sort of thinking has been debunked MANY times over, much like creationism and phlogiston, so we don't waste our time wallowing in such ignorance. If you persist in this, you'll be required to leave. Nobody here is interested in going backwards; discussion should be meaningful, and promote learning. IOW, stop making moronic monkey noises.

Removing odour from TPR ?
The Pine-sol disinfectant I used had propylene glycol in it, and I would imagine this solvent did more to remove the bad smell than the pine scent. Perhaps try a mixture more focused on PG (should be readily available with people making hand sanitizers these days).

Does drinking water make you sick?
We have a couple of past threads that mention this, if it helps. As Markus says, as long as we're not put in a position where we're advising anybody about a medical situation, it won't run afoul of our rules.

Removing odour from TPR ?
I had a rubber mat that smelled bad. I cleaned it with a strong solution of water and Pine-sol, and let it dry in the sun. It worked pretty well, but I know some folks feel the same about the smell of pine (I'm talking about YOU, Finland).

I thought this was the best analogy, and I'd love to hear MigL address it. It's too good a point to pass up.

Can Science Make us live longer?
! Moderator Note You really need to stop bringing these sources up outside of the Religion/Philosophy sections. They aren't scientific at all. Isn't the real challenge keeping the mind functioning along with the body? Who wants to live past 100 if it's all retirement village and senility after 85? How advanced is the science when it comes to being spry and sharp-witted when you're 120? Of course science can make us live longer, but can it make those later years more worthwhile? I'd settle for sound mind alone, really. Pull me around in a wagon if you have to, as long as I can think straight and tell the young folks all about it.

Can you be a scientist and still believe in religion?
I recommend you wash your brain out with soap for thinking this.

Absolutely not! You just read some Dostoyevsky and started Russian to conclusions.

Some example threads in Politics or Other Sciences would be better than a list to demonstrate interest in the subject.

How Trump Could Steal The Election
Push back doesn't equal hate, and neither do countersuits. Being firm with children seems to be an effective formula.

How Trump Could Steal The Election
I've always maintained that our biggest problems economically are caused by mixing the goals of public and private ownership. Public works need to be as free from profiteering as possible, but we go out of our way to include private interests, and it almost always ruins the efforts. Every American can send a letter to any other American for the same low cost because the system wasn't designed for profit, but that's being derided as socialism instead of using the right tool for the right job. IOW, both major parties serve a different set of billionaires. The People need to reassert their ownership or we're going to end up with a king who owns everything again.

Fuck THAT. Easy to say when you have publicly-funded healthcare during a pandemic. Compromise hasn't worked in the US since neo-conservatism took root.

Are you atheist?
At least you can observe your fanged snake god among the tubes in the device. There's evidence your sacrifices are being acknowledged, right? My Humanism is being tested currently. When people reject their intelligence in favor of more primitive animal behavior, then what makes us different?

Extraterrestial life searching
It's an excellent question! I'm not sure about chlorine, but I have heard arguments for an ammonia-based lifeform. It's not assumed in science that water is required for life, just that we know how well water supports it. It's also our best chance to find life similar to ours. You should study water. It's an interesting molecule, with some unique properties. I think it's the only substance where its solid state floats in its liquid state.
