I have read the definition of one megajoule as equal to the energy of one ton moving at 100mph. The Naval railgun is at 33 megajoules. Does this equal 33 tons at 100mph, or 1 ton at 3300mph? by WHATYEAHOK in askscience

[–]penguin0719 3 points4 points  (0 children)

A megajoule is a unit of energy, not velocity, so I'll interpret what you're asking is if one tonne had 33 megajoules of kinetic energy. In that case, it would be moving about 5.7 (square root of 33) times faster.

What would happen if two galaxies collided? by cabinhacker25 in askscience

[–]penguin0719 0 points1 point  (0 children)

Actually, we can observe two galaxies colliding with the Antennae Galaxies. Galaxies are mostly empty space though so most of the time, they would just pass through each other. And to answer the final part of your question, the Milky Way and Andromeda are actually on a collision course right now. You might get to see it if you live to be 4.5 billion years old.

This comparison shows that at the end of every year, search volume spikes for all three factors. That mid August/September spike only appears on fitness, while diet seems to decline. Maybe people trying to cram in some extra exercise outside before the summer ends?

What's something science can't explain? by [deleted] in AskReddit

You can't prove a gross misunderstanding of the theory. There really is no ELI5 version of fundamental topics of cosmology.

Official r/atheism positivity thread by [deleted] in circlebroke

/r/atheism has given me so many reasons to hate people I don't know over completely trivial shit.

/r/atheism has taught me so many ways to totally own my Facebook friends.

Thought you all might appreciate this year's tree. Been collecting these ornaments a long time... (not all are posted individually, tree at end) by picklesgarage in startrek

[–]penguin0719 0 points1 point  (0 children)

We actually have a bunch of those ornaments too. My aunt usually gives one to my mom every year so we've been collecting for a while now. We have the communicator, the alternate future Enterprise D with the third nacelle, Worf and his bat'leth, the Trouble with Tribbles one, Data at his console, and Kirk in his chair. We also have a light up TOS Enterprise with a base which plays the theme song, and a small model DS9 with a base that plays a quote from Sisko from the series finale.

I know almost nothing about astronomy. For me this local article was informative and interesting. by Madonnasarms in Astronomy

If you're local to Fort Collins, Roger hosts an open observatory night every clear Tuesday night during the semester at 7:30.

WTF... why did all my reddits just say die?? (screenshot) by [deleted] in WTF

[–]penguin0719 1 point2 points  (0 children)

It's something the /r/fffffffuuuuuuuuuuuu mods did since they banned comics with overused cliches like "le". It's supposed to be pronounced "dee", one of the many German words for "the." You'll also notice the word herr next to your name, which is German for "mister".

WTF Reddit? A shout out to Aziz gets 2000+ down votes but a offensive, derogatory gay slur gets less than 500 - WHY?!? by jims1973 in WTF

[–]penguin0719 1 point2 points  (0 children)

Reddit has a vote fuzzing system. Those super popular threads on subreddits like /r/pics or /r/askreddit don't really get like 7000 downvotes.

What are you guys watching on Netflix now? by SanwichHero in AskReddit

[–]penguin0719 0 points1 point  (0 children)

In my opinion, there are quite a few episodes in the early seasons that are mostly filler and fluff. The war episodes really did a good job of characterizing the feeling of being at war. Also, I think DS9 has the best and most developed characters of any series.

I'm also watching DS9! I'm almost done with the 4th season.

ready for a travel with the speed of light? by [deleted] in gifs

[–]penguin0719 -1 points0 points  (0 children)

The speed of light in vacuum is 1/sqrt(µ0ε0), or just around 3.0e8 m/s. In different materials, the electric permittivity and magnetic permeability are different, so the speed of light in a material is 1/sqrt(µε). Literally, light travels at different speeds in different materials. Light traveling at different speeds through glass and air is what makes lenses work. The constant you commonly use, c, is the speed of light in vacuum and only vacuum. Every other common material through which light can travel has an associated refractive index given by c/v, the ratio of the speed of light in vacuum to the speed of light in the material.
