My dad was telling me that they are trying to create anti matter.

 

The thing with that is that whenever anti matter makes contact with matter, it vanishes.

 

The reason for wanting anti matter is for his energy potential....

 

So they are trying to store it in an electromagnetic field, its made at heats such as those in that machine in Switzerland. e.g the big bang.

Arent you talking about C.E.R.N?

 

I dunno man, the antimatter thing seems impossible. unless Matter vanishes when created antimatter wich means...... HOLY SHIT WTF MASSIVE BLACK HOLES MUAHHAAHAHHA END OF ZE WORLD? ay? nah.

Like I said, I think they will use an electromagnetic field or something similiar to seperate matter and anti matter.

If the Earth's rotation around the sun in time is set at one year (365 days + 1 day every four years), and the earth's rotation around itself is set to 24 hours, are these time concepts done as statistics? Or to put it another way, is a day today as long as a day was 100 million years ago? We know that mass attracts mass and therefore should probably also assume that the earth is closer to the sun now than it was 100 million years ago, but does it have an impact on how long it takes for it to get around the sun?

 

Alright time to tackle this a few days late :-P Earth's rotation depends alot on our moon actually. Currently the moon is pulling further away from Earth, we are talking fractions of inch a year. As it gets further out the rotation on its axis will slow and eventually some time way in the future the moon will be only seen on one side of the planet and we will have really long days.

 

Hey, that reminded me of another question:

 

If humans ever invent some spaceship that'll get you out in space _REALLY FAST_, would it be possible to see the past on Earth? Like when we watch stars, we watch the light that they sent out millions of years ago, the same thing must apply to the Earth?

 

So if we fly one lightyear away from Earth in 1 hour, we see the light as seen on the Earth 1 year ago minus 1 hour? Can't we just travel 2000+ lightyears away from Earth and watch Jesus and such?

 

Havok pretty much nailed this one in the post above mine.

Anti-matter has already been created. Its just not a whole lot of it. If I remember right about 20 grams are made each year at a cost of 6 Billion dollars. You have the therory right lux, stored in an electromagnetic vaccuum is the plan once we create enough to store. But that technology is quite far away.

Addition to Saxe's theory, but instead of going very fast we just get to the desired location using a wormhole, no need to travel at the speed of light, just use a shortcut to get to the time where we can see the past Earth

We touch light speed stuff a lil in physics (apllied physic so newbie stuff)) ..Its so fucking weird and beyond what seems logical. Im no genius so spiked might be able to explain more but for me its so weird how the closer you get to the speed of light, the slower the time and the more heavy everything gets..and distances get shorter. And if you you would actually reach the speed of light things basicaly stop moving and their weight is beyond anything amaginable. HOW THE FUCK DO WE KNOW THESE THING WE NEVER GOT CLOSE TO THE SPEED OF LIGHT...I dont get it and light has a weight by the way since its pulled down to the earth by gravity...

SOMEONE GIVE ME SOME FUCKING LIGHT ON THE MATTER...get it lol:rant:

For all things light, check out special and normal reletivity. Lots of neat things on there.

 

Wormholes are kinda pointless at this point. For anything worthwhile to go through the wormhole would be huge. A wormhole the size of our solar system would be able to send a microchip through it safely. Of course this is all in therory.

Well if an asteroid hit earth enough to mess up the orbit I think that asteroid would have to be so big that it would destroy the planet into millions of pieces. Around the size or Mars is what I'd think. But as far as altered orbits. One way to think of it is, do you think time is different on Mercury? Its orbit is roughly 3 months. The simple answer is no. The speed difference would show "negligable" boosts. But if our orbit shortens, that also means our planet would heat up as well, so we'd noticed alot more than just shorter years.

 

Now millions, possibily, billions of years from now when our Sun starts to turn into a red giant star; our orbit is predicted to increase due to the unstable gravity of the Sun. Now this would happen subtlely and this increase will actually help the planet when the sun goes through its Red Giant phase as it will serve as a warning to clear out from the solar system because the Sun will go supernova soon. (In fact I am kinda writing a short story about this same subject so I'll let you know when I get it somewhat done.)

 

As far as reletivity, you have to get really, really close to speed of light for time to dialate. And at that rate, you really wouldn't notice a difference. Thats the weirdness of Einstien's reletivity. The simplest way to explain, time only dilates for the people who would travel near the speed of light and they really wouldn't notice that time slowed. Its the twin rocket senario. One twin leaves earth at near the speed of light goes 10 light years out and comes back. To him it has only been about 20 years. But for his twin on earth that trip actually took 80 years. So time for us would not really change.

Sorry I went science geek on you :-P
