Matter, Dark Matter and Dark Energy

Featured Replies

The cosmic soup seems to be made of these three items...

 

Can someone...briefly....explain them..and what percentage in the soup they comprise.

Please... the ellipsis is not to be overused... you demean its value if you do...

I'm pretty sure someone was discussing dark energy in the physics forum last week.

 

Go to the search page up there --^ and have a look.

Well, it turns out I have found out the answer to my own question thru the old fashioned way...reading a book.

 

Only 5 percent of the known Universe is made up of Matter.

 

The rest is a mysterious stuff called Dark Matter. We really don't know much about it. In fact some have argued that the Universe is "invisible". We can't bottle the stuff or take with us to lab, but its there.

 

On top of that, there is another little thing called Dark Energy. Anti-Gravitional by its very nature it is causing the Universe to expand forever.

That's not allowed. You have to make the same mistakes over and over again and ignore anyone who tries to tell you otherwise.

I think that string theory completely explains thatthese other thing which are unfindable are in the other spacial dimension we are currently unable to detect.

 

I can only wonder.

The superstring theories aren't exactly doing much atm.

Superstring theory publications appear regularly by Kaku and are constantly rewriting physics.

It's not complete though. Whilst individual sections may be busy, and publishing goes on, the theory doesn't matter until it's accepted by peer review and taken into canon, as it were.

Complete? No not at all...

 

What do you mean "until" it's accepted by peer review.

 

The entire physics community backs string theory more than not. The majority is definetely for it and this is evident in my contacts.

 

This is why it's being developed so fast.

Isolated bits may work, it's if it fits into a whole that has to be accepted by peer review.
