That CAN'T be true! / Re: Surviving a lightening strike
« on: Yesterday at 01:08:08 »
90% of the people survived, that doesn't mean that they were feeling all that great.

Physiology & Medicine / Re: Why do I find it easier to run up steep hills than walk up them
« on: 21/05/2022 15:34:07 »
Well, I'm not sure why you find running more comfortable.  As an aside my horse seems to always want to run up steep hills when I ride him instead of walking also.  I am not implying that you are part horse.

New Theories / Re: what is temperature?

Quote from: hamdani yusuf on 21/05/2022 11:29:58
Different types of thermometers have their limits in range and linearities. How would you calibrate them against each other, if temperature is not well defined in standardized definition?
After 16 pages you sound more confused about temperature than when you started.   :o

So it seems only short people experience this where walking becomes harder than running up steep hills but I can't find find the answer as to why.
Please define the term 'harder' in this case.  If you run a 100 yards up a hill vs walking your heart rate will be higher your body temperature will be elevated and your muscles will produce more lactic acid so I am not sure what you mean.

Physics, Astronomy & Cosmology / Re: Is there a net heat exchange between water and ice at 0 degree C?
« on: 21/05/2022 14:29:43 »
Quote from: hamdani yusuf on 20/05/2022 15:02:45
May be it's not relevant to the title or theoretical consideration. But it's relevant if we want to get experimental evidence.
A poorly designed and executed experiment gives meaningless results.

New Theories / Re: Is life in this Universe a one-off occurrence?
« on: 20/05/2022 17:41:03 »
Quote from: tonylang on 20/05/2022 16:28:46
The LINE hypothesis proposes that the matter-antimatter imbalance that exists in this universe is a consequence of the universal instantiation event (UIE) followed by many cycles of universal expansion and contraction phases. Each cycle is punctuated by a universal transition event (UTE).
This sounds like a Bunch of Crap (BoC).

Physics, Astronomy & Cosmology / Re: relativity paradox or misunderstanding?
« on: 20/05/2022 15:55:42 »
Quote from: paul cotter on 20/05/2022 15:41:14
A photon of light leaving such a galaxy will travel any distance in zero time in it's own frame of reference.
A photon does not have a valid inertial rest frame in relativity. 
Quote from: paul cotter on 20/05/2022 15:41:14
So the question is will the photon reach the the distant observation post or as the horizon theory would suggest will it be lost forever in the permanently stretching fabric of space?
The photon won't be 'lost' it just will never reach us.  Can a photon just continue on if it never hits something?  Yes.

Wasn’t India using a doxycycline and Ivermectin combination for early treatment with good results?
No.

New Theories / Re: Re: Is radiation pressure a significant factor in dark energy?
« on: 17/05/2022 13:15:44 »
Quote from: samcottle on 17/05/2022 12:41:28
gravitational fields are formed by ephemeral, tunneling electrons; these electrons appear for roughly one unit of the Planck time in the gravitational field of the object to which they belong, move through space in tandem with the object's rotation, and exchange W particles with protons (if they're within the electroweak range), or absorb/emit a photon, or exchange a neutral current with a neutrino (leading to an oscillation, or change in flavour), depending on the sort of particle they're closest to when tunneling to a new location.
How does that form a gravitational field?
Quote from: samcottle on 17/05/2022 12:41:28
If this is the truth, then it would account for the reflective capacity, via general relativity, of gravitating bodies (since we know, of course, that electrons reflect light).
Where does GR talk about reflective capacity?  Dark matter does not interact with photons but does have a gravitation field, how does that fit into your idea?
Quote from: samcottle on 17/05/2022 12:41:28
Extrapolated to galaxy clusters, as in the vase of 'dark' energy, we could surmise that, since the Big Bang, huge amounts of radiation (photons) have been accumulating between galaxy clusters and the radiation pressure generated has led to the accelerating expansion of the universe.
Wouldn't this radiation be easily measured on Earth?

General Science / Re: Is it safe to transport hydrogen gas compressed into a water tank?
« on: 15/05/2022 18:27:01 »
Quote from: vdblnkr34 on 15/05/2022 15:47:09
I didnt get to the part what to use to build it. The idea to compress hydrogen into water as a preventative matter. And bigger the capacity.
Are you saying you want to dissolve hydrogen into the water?

Is it safe to transport hydrogen gas compressed into water tank?
The quick answer is no.  Water tanks are not designed to hold compressed hydrogen.

Physics, Astronomy & Cosmology / Re: Is this a paradox in general relativity?
« on: 14/05/2022 20:57:17 »
Quote from: Dimensional on 14/05/2022 06:08:03
Now my thought experiment is about what might happen if an object moves really fast in front of the nose of the ship where the lower clock/event is.  To make the object appear in front of the nose almost instantaneously, we will say that it came from another spatial dimension z going into your screen.  For simplicity sake, let's say this interaction happens at the lower clock/event (where the nose of the ship is).
I'm not getting this scenario.  Does the intercepting object have to be moving very fast or can the scenario be that the ship hits a pebble.

Quote from: Dimensional on 14/05/2022 18:45:04
The 3 events are the 3 clocks that I was referring to.
As far as I could see there were only 2 clocks, one on the ship and one on the ground.

New Theories / Re: What is the real meaning of the most-distant-quasar/galaxy?
« on: 14/05/2022 16:43:05 »
Quote from: Dave Lev on 14/05/2022 16:31:38
Anyone that ignores the observation makes a stupid assumption.
So stop doing that.
Quote from: Dave Lev on 14/05/2022 16:31:38
Why do you think that we should ignore the clear observation of those messy eater SMBH?
What do you mean by messy eater?
Quote from: Dave Lev on 14/05/2022 16:31:38
Why do you think that the most-distant-quasar can eat its total food in just 570 MY while all the other SMBH that we clearly observe can't eat even 0.00...1 in a similar time frame?
I don't think that.  Why do you think, "while all the other SMBH that we clearly observe can't eat even 0.00...1 in a similar time frame"?

Quote from: Dave Lev on 14/05/2022 12:00:57
So we can easily calculate the estimate growth rate of a SMBH.
Let's assume that by average we get 4 M solar mass per 12BY.
Based on that understanding we can estimate the time frame that is needed for a SMBH to gain 1.6 B solar mass.
1.6 B / 4 M * 12 BY = 400 BY
So you have proved if you make a stupid assumption you get a stupid answer.  I'm pretty sure everybody already knew that.

Have you heard that someone defined pi = 3?
I'm beginning to think you enjoy the feeling of being confused.  You now seem to not even know what a definition is.  I don't get you at all.

Don't worry, your stuff is all garbage anyway and you should be banned in a short time.

Your picked answer is different than what the actual results are.
Do you have an idea how to get the first possible result, i.e. both cups retain their ice/water ratio?
Of course!  Why are you asking, haven't you read your own thread?

Quote from: hamdani yusuf on 13/05/2022 15:39:22
Did you make correct prediction?
Yes, I predicted your experiment would fail because there is going to be a delta T between the environment and your ice bath since you do not have the equipment to accurately hold the temp at exactly 0C.
Quote from: hamdani yusuf on 13/05/2022 15:40:40
I already knew that. What I want to know is, what else drives heat transfer?
If there is no delta T, then nothing else matters since there will be no heat transfer.

Quote from: hamdani yusuf on 13/05/2022 14:28:49
I also learned that gravity and buoyancy play significant role in determining the results, which need to be addressed in upcoming experiments.
What you should have learned is that heat transfer is driven by the delta T.
