Spacetime is not ... ( 4 days ago by izlude2)

Spacetime is not flat. It is not curved either. My recent discoveries (well theories) show that it is layered. layering 2D plains creates a 3D world. layering 3D planes creates a 4D world and so on.
Notices how in photos of galaxies, they sit in various spatial locations (scattered) imagine a bowling ball on a trampoline, and the a bigger bowling ball mysteriously "flying" above it. It isn't really flying, there is just another spacetime plain supporing it. Black holes are 4D objects.

A black hole is a ... ( 3 days ago by tobysangster10)

A black hole is a region of space in which the gravitational field is so powerful that nothing, including electromagnetic radiation can escape its pull after having fallen past its event horizon. The term derives from the fact that absorption of visible light renders the hole's interior invisible, and indistinguishable from the black space around it.While general relativity describes a black

hole as a region of ... ( 3 days ago by tobysangster10)

hole as a region of empty space with a point-like singularity at the center and an event horizon at the outer edge, the description changes when the effects of quantum mechanics are taken into account. Research indicates that, rather than holding captured matter forever, black holes may slowly leak a form of thermal energy called Hawking radiation and may well have a finite life. look below 1st

You may be rite that time traveling may not be possible, but then it might be possible mentally. This has been proven by many people who are able to see into the future/past (of other people). YOu could also notice by sometimes you feel time goes so slow and sometimes time goes really fast. This is also an effect of Time Traveling Mentally. It is because your mind is unstable and may move faster than speed of light if well trained (unliterally).

Well, we may both be right and we may both me wrong. I think that in the future, scientists will know anything from the subatomic atom to the universe; but I don't think we will ever fully understand that which is ourselves and our own brain.

lol I can imagine some really nerdy black girl trying to seduce some guy after an astronomy lecture or something. sounds like something I'd see on family guy.

How can these ... ( 19 hours ago by Jeorney)

How can these strings have such density & tensile strength & only be one atom thick. One atom is not even enough to form a molecule. If this is not psudoscience, couldn't it be that these strings are not physical.
Btw, they are saying now that black holes came before the galaxies.

i'm baffeled by this.... Black holes are insane,
I haven't researched them a whole lot, but its similar to this
take a bottle, light a small fire, put a balloon over the top, the fire sucks the balloon in cause it has used up the oxygen/space
A black hole is simlar to this but on a insane scale? It sucks everything in, even light can't escape from it
