What is the biggest number that describes or expresses an actual physical property/phenomenon?

>>6130457

beats me lol

What makes the forces of the universe work?

So I just found this image in /v/.
Was wondering , is that a huuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuge sun in the middle of the galaxy?

I don't know if it really is possible or not, but right now every clue seems to say "no".

Quantum entaglement cannot break the speed of light if you want to send information.

It's possible that for example some galaxy if moving from us faster than speed of light, but that's kind of cheating, because it's space between us is growing.

ITT: We create the largest defined number ever.

Astronomy problem, sorry having trouble with this question

What is the mean (average) angular diameter of the Moon as observed from the Earth? Express your answer separately in all of the following units: radians, degrees, arcmin, arcsec (4 separate answers). (actually of course, this question has nothing to do with the Moon, but is about angles. Look up the diameter of the moon and the mean Earth-Moon distance in the back of any astronomy book). Do *NOT* use any trig function- USE THE SMALL ANGLE APPROXIMATION to find the angle in radians, then convert to the other measures of angle.

What is the small angle approximation?? I'm just not fully understanding what this problem is asking. Any help would be greatly appreciated

Being significant means having an impact, causing long-term change, etc. Humans are insignificant because they, along with their accomplishments, will one day be destroyed, whether it be in the explosion of the sun, or by their own hands. The universe will carry on like we never existed. All of our discoveries, our creations, our art, and our individualism will be burned in the furnaces of stars, only to become stardust once more.

Best be trolling.

amazing discovery op

>OP wants us to email moot
>mfw

trying to find the name of the theory in which time has a set course and cannot be manipulated, you do not choose your own fate and if you were able to go into the past, the universe would prevent you from fucking up the timeline. does /sci/ have any idea what the name of that theory is called?

>Quantum mechanics allows, and indeed requires, temporary violations of conservation of energy, so one particle can become a pair of heavier particles (the so-called virtual particles), which quickly rejoin into the original particle as if they had never been there. If that were all that occurred we would still be confident that it was a real effect because it is an intrinsic part of quantum mechanics, which is extremely well tested, and is a complete and tightly woven theory--if any part of it were wrong the whole structure would collapse.

>But while the virtual particles are briefly part of our world they can interact with other particles, and that leads to a number of tests of the quantum-mechanical predictions about virtual particles. The first test was understood in the late 1940s.

>Thus virtual particles are indeed real and have observable effects that physicists have devised ways of measuring. Their properties and consequences are well established and well understood consequences of quantum mechanics.


That is how the big bang could have occured.

>your face when /sci/ today is literally 100% religious threads

I know it's usually mostly religion threads, but god damn, before today you used to be able to actually discuss stuff related to science or math. Why don't mods just ban these people?

Supermassive black holes

How the fuck are they formed?

Okay /sci/.

How do you calculate speed, taking the speed of light in consideration?

>Physics not relevant in over 50 years
Oh so a new rocket/missile/skyscraper/airplane hasn't been made in over 50 years?

Where the fuck do you live?
