SpaceGrandpa#6827: short answer you can't
SpaceGrandpa#6827: long answer you can theoretically but it won't happen in your life time
SpaceGrandpa#6827: if ever
SpaceGrandpa#6827: you'd have to be 4.5 billion light years away
Enzy#2481: Ah
Enzy#2481: That sucjs
Enzy#2481: Sucks
wub#6114: moey, the way a wormhole works i... |
wub#6114: well yeah, there's still that
+|A.O|+#3251: also, wouldn't one have to speed up beyond light speed and slow down back again?
wub#6114: to go through a wormhole?
+|A.O|+#3251: as far as i know, you'd become temporarily infinitely massful
wub#6114: the distance is shorter
+|A.O|+#3251: @wub no.. not wormhole
+|... |
so at some arbitrary speed close enough to light speed, one may count 1 minute on their clock while the world experienced 1 millenia
+|A.O|+#3251: time never runs back

SpaceGrandpa#6827: Which
SpaceGrandpa#6827: As far as we can tell
SpaceGrandpa#6827: Don't exist
+|A.O|+#3251: well, how would you convert matter into tachyons?
SpaceGrandpa#6827: But it's *theoretically* possible
+|A.O|+#3251: converting matter into ```matter*i```?
SpaceGrandpa#6827: uh weak interaction, if you could ... |
+|A.O|+#3251: for a simple illustration..
for you to accelerate into light speed, you must push matter behind your at a speed bigger than light's speed
SpaceGrandpa#6827: If you have mass, you can't go faster than light
SpaceGrandpa#6827: You can't even go at the speed of light
+|A.O|+#3251: and when your push is maxi... |
+|A.O|+#3251: but has the same results as the relativistic situation too
SpaceGrandpa#6827: no it does not
+|A.O|+#3251: well, here it is..
to stay at a speed, in vacuum, you need no force..
to increase speed, you need to push something back..
you only will increase speed if you manage to push it faster than your curr... |
+|A.O|+#3251: now, since momentum is conserved, to push a lighter object back, you need it to be pushed into a higher velocity than light
+|A.O|+#3251: which is not possible
+|A.O|+#3251: hence.. Newtonian mechanics also proves why one can only approach light speed, but not reach it..
+|A.O|+#3251: this assumes though,... |
Red Triangle #53#7873: in the reference frame stationary to the ground you have a lot of momentum
Red Triangle #53#7873: because velocity is a relative state
+|A.O|+#3251: yes..
+|A.O|+#3251: so?
Moist Mayonnaise#5570: @+|A.O|+ so like you were told earlier, in Newtonian mechanics you can always just boost your referen... |
+|A.O|+#3251: just need to get my math together
+|A.O|+#3251: i know there's a speed limit because the energy required to make that 0.01% of the way to light speed is a limitless energy barrier
+|A.O|+#3251: there has to be math supporting it
Red Triangle #53#7873: electrodynamics predicts the speed of light. Special r... |
Salt#1137: There was an attempt in the 19th century to find something called the aether. If true, it would provide a true inertial reference frame, but more importantly here it would mean that the speed of light is not constant, and can be exceeded. This was done by measuring the time it takes light to bounce off mirro... |

Hwaet#4348: I see
Augustus#0236: the 14", 16", 18", and 20" chinese mirrors generally need human intervention to make them usable at all
Augustus#0236: but they still aren't always great

Augustus#0236: yeah
Augustus#0236: I just made a 6"
Augustus#0236: I'm about to make another 6", but it's a compound design and the mirror will be quartz instead of glass

TheLostVertex#3014: yeah, but that isnt what he said at all
Hwaet#4348: well the semi minor axis is slightly bigger than 1 AU
Hwaet#4348: you would have a gap of 17.7 km per side
