Starship Asterisk*

Hello All

Hello Orin

I have read the above links, I cannot see reality. The comments are not scientific and their information on black holes and wormholes are for movie makers.

But! it does seem interesting

Andromeda is 2.2 to 2.5 MLY. The Milky Way and Andromeda is moving toward each other at 300,000 mph or about 83 mps. So actually wouldn't the Milky Way and Andromeda be closer since what we see is where Andromeda was 2.5 million years ago? And being that gravity accelerates as objects get closer; they may collide sooner than expected. Not that it makes much difference.

Hello All

I thought that gum was a bit off

Hello Orin

You may be right and maybe gained close to one light year.

Or should I say lost one light year

186,000 miles (the speed of light per second)
X 86,400 seconds (the number of seconds in a day)
X 365 days (the number of days in one year)
-----------------
5,865,696,000,000 miles per year

MW and Andromeda moving toward each other at 83 mps X 86,400 X 365 = 2,617,488,000 mi/yr

2,617,488,000 miles X 250,000,000 years. = 654,372,000,000,000,000 miles / 5,865,696,000,000 = 1,134,455.6 light years closer than appears. If my math is correct. That doesn't account for the acceleration of gravity.

Hi Harry! If my math is correct than is 1.13 million light years closer than what we can observe. Even though that seems like a lot I doubt it would make much of an observable amount considering the vast distance involved.

Hello All

Hi! orin

Mate I calculated that in my head, guesstimate. Out by .13 light year ain't so bad as rocky would say.

Boy,
If Andromeda is seen as 2.2mly away, is 1.1mly closer than it appears, and is 5 times larger than originally thought, It is actually 1.1mly away and is approx 1mly dia.


Are we merging yet????

Your right BMAONE23 I figured from 250myl instead of 2.5myl so if I devide by 100 I'll have the right answer. Thanks That would be 11,300 ly closer tham appears.

.

well,
guess i'll have to cancel the merger party

Hello Orin

There is something wrong with your calculations.

If Andomedia is 2,200,000 Myrs away

Than we are probably less one light year about.

This makes it 2,199,000 light years away.

Better party now; I don't think we'll be able to make it to the big show!

Hello Orin

I'm a galactic traveller, i have a time machine and with it I will go into the future and see the collision. I will take an image of it and come back.

Smile!!!!!!!!!!!!

Party on mate.

The only limitation on the relative velocity reachable is physics as we understand at the moment. The way we view both space and time which IMHO needs to change if we are ever going to be able to really explore the Universe.
If that change ever comes in my lifetime I will be very surprised.

Well,
The world is full of absolutes:
1) The world is absolutely flat. (if you travel too far west, you'll fall off the edge)
2) Man never traveled to the moon. (It was all done in Hollywood, everyone knows that)
3) Man cannot travel faster than 35 mph or his skin will be torn off.(whoops, WRONG on that one)
4) Man will never travel faster than sound or his skin will be torn off. (whoops, WRONG on that one too)
5) Man will never travel faster than light! (maybe.......maybe not)
6) Big Bang...Steady state...Big Bang...Steady state...Big Bang...Steady state...(still up for debate??? Nothing has been proven ABSOLUTELY)

Hello BMAONE23

Your abolutely right.

U R too funny Harry

The best absolute is spelled without the [e] Absolut

clearely a true statement

Hello BMAONE23

The idea is to have fun with this site.


Our IQ goes higher with fun.

Clearly; Harry, this thread is about speed; but a little levity is always nice. Thanks for your imput though.

Imagination already travels faster than the speed of light.

Consider a quasar, 13 billion light years off, what it must look like today...

You just broke the speed record!

You can travel back in time by looking through a telescope but only our imagination lets us travel into the future! Our imagination has been pretty accurate; however!

So we can only go as slow as our imagination? Don't blink you'll miss it.

How fast can sound go? The other day a sonic boom was heard in the Council Bluffs; Omaha area. It appears a fighter jet passed over going just under the speed of sound; however, because of atmospheric conditions, the speed of sound was slower then normal and a sonic boom was produced. So sound must travel faster or slower depending on the media it is traveling through. Could sound travel a lot faster given denser media to travel through?
Probably could have started a new thread with this but it seemed fitting here.

Thanks Makc! I never paid much attention to the speed of sound other than through the atmosphere before!

I didn't know studies were made of sound speed in other media; it stands to reason though.
