Coming Soon đ At the beginning of April, youâll be
introduced to a brand-new GoComics! See more information here. Subscribers, check your
email for more details.
According to what I learn in school is that the smaller the planet (or the moons that orbit them), the lighter their gravity is. The bigger the planet is (like Jupiter) the heavier the gravity it is.
The gravity wells of planets and moons will also bend light. Itâs just that the effect is so small at that level that we canât observe it, yet (so far as Iâm aware). But such bending is equally predicted by theory.
We are already at the point where time dilation (also predicted) can be measured with regard to spacecraft orbiting the Earth. So the bending of light in the same gravity well should also be happening.
Itâs just that the spammers are out early today so gone early. Yesterday they started about noon after most of you were off line. I was late getting to the comics and flagged one just one minute after it posted.
It was described to me as,âBook Smart vs. Street Smartâ. My son and his friends are the, âBook Smartâ crowd and theyâre brillant but put them in a day to day decision making situation and theyâre lost .
Calvin âput the squeeze on Momâ. Mom should âmop the floor with Calvinâ!
When life gives you lemonade, what then? Lemon oils are used in floor polish. Mop the whole floor with the lemonade, or is that squeezing too much out of it?
Okay, I think Iâll âpeelâ out of here now!
Gretchensmom, it was one of those pitchers that bounced! Plus if you are mopping the floor wouldnât you just mop the whole thing? I donât know Iâve never been a mom!
While skating along with the pitcher of lemonade, Calvinâs center of gravity changed suddenly producing an intense look of gravitas on his motherâs faceâŠ.
Ah, all of the wordplay is making me a âgraveâ person, much like MercucioâŠgrave, gravity, gravitasâŠisnât that the Latin for bad punning? Hope your day isnât soured by all the spilt lemonade!
I donât knowâwe always got first dibs on cleaning up our messes. We learned how to wield a mop, anyway.
And, yes, any massâeven one as small as an electronâcurves space-time ever so slightly. Itâs not very measurable, however, on less than planetary scalesâand the larger the better. IIRC, two masses of lead the size of a house (or a moderate skyscraper) would take millennia to move together over a foot solely under the attraction of their mutual gravity. But it takes under a second for the Earth to fall back to my feet when I push it away by jumping.
LeslieAnne: Youâre absolutely right. If I have to haul out the mop and bucket to clean up a mess in one area I might as well just do the whole thing while Iâm at it!
OK guys and gals⊠if ALL mass has gravity and therefore ALL mass exerts a force and the third Law of Newton states that for every force there is an equal but opposite reaction force such as I am attracting the Earth equally as much as it attracts me then what is the reaction force of star on light if light is not matter hence no gravity?
Light does have massâthe rest mass of a photon may be zero, but it moves, and has energy, which can be calculated for each wavelength of photon. Hence, it is affected by gravitational fields, according to Relativity. Therefore, one early, famous test was to photograph the sky during a total solar eclipse and check to see how much the star images near the sun movedâbecause the light was traveling in a hyperbola rather than in a (virtually) straight line to us.
Also: thatâs how a Black hole event horizon is defined: itâs the point at which escape velocity is higher than the speed of light, so that even light is pulled into the hole by the gravity.

Calvin understands the gravity of the statement- Light is actually deflected by gravity. He is just acting dumb.
painterplumber over 14 years ago
Ha Ha. Good ones. You guys are sharp this morning.
Just as much fun reading your comments!
Bittermelon of Truth over 14 years ago
Two corrections, Calvin⊠not so much planets but more massive stuff like galaxies and stars.
Iâm surprised he knows so much about Einsteinâs relativity theory http://en.wikipedia.org/wiki/Gravitational_lens
(as opposed to, say the relative importance of not telling Mom immediately about his accident) :-P
paha_siga over 14 years ago
Well, he didnât tell IMMEDIATELY! ;) He started by impressing her with his knowledge on gravity.

And why were you wearing roller skates in the house, Calvin?
Sandfan over 14 years ago
Calvin fails to understand the gravity of his situation.
@Josh 1360: Think mass, not size. Small objects [dwarf stars] can have enormous gravitational fields.

Pouring lemonade while wearing roller skates? That just cannot turn out well, no matter what âŠ

moronbis, Light is actually affected by the Dark Sucker Theory http://www.ultimatecampresource.com/site/camp-activity/the-dark-sucker-theory.html

It gives me great pleasure to say that I donât see any spam right nowâŠ
Hoomi over 14 years ago
Itâs certain Calvin doesnât read âThe Family Circus,â or else he would have said that Notme or Idaknow had actually spilled the lemonade.
Rakkav over 14 years ago
I was wondering if someone would catch that, RinaFarina⊠:)
Count it as being too tired to think on the one hand and too lazy to change the error on the other.

Some strips are heavy with spam. Calvin you must be paying attention to class to talk about matter.

He must have been trying to âroll toward the dipâ when he slipped.
ratlum over 14 years ago
Yes I wonder,how can he be so smart. Is that true about gravity and light ?
coffeeturtle over 14 years ago
It is true ratlum, and his analogy was dead-on. Bill Watterson must have been pretty interested in science. ;-)
tmick2001 over 14 years ago
Calvin is probably self-taught when it comes to science and doesnât pay attention to subjects he has no interest in (like myself).

Based on the size of that lemonade puddle on the floor, just how big was that pitcher anyhow?!?!?
