/sci/ - Science & Math

i could sit here and type you an essay on why you're assuming too much, but i'd rather just sum it up by saying:

we don't have the technology yet to detect terrestrial planets in exosolar systems.

if their really is no end or beginning of time than how do we know there really isn't a true top to the barrel when they're has to be one? if the water freezes when under the certain pressures of which have been done then how does there be one? thanks for help

How do we make a mark?

Hello, /sci/.

I'm currently a junior in High school, and I am thinking of my future college options.

The major that I would like most would be Astronomy, but I also am very talented in Biology.

Which would be best to follow, and what are some other successful majors?

Hey /sci

I have a couple questions:

>Recent theories suggest that Black Holes are actualy some kind of portals leading to a White Hole that spews out the matter that the Black Hole absorbs.
How is that theory possible? A Black Hole is nothing more then matter ultra-compressed to such densities that gravity is greatly increased to the point even photons cannot escape. How would a portal be formed? Wouldnt you just collide with the compressed matter?

>Current scientific studies on Black Holes suggest that Black Holes would eventualy vapourise away due to Quantum effects "teleporting" particles away from the Black Hole.
Wouldnt those particles end up being re-absorbed by the Black Hole due to immense gravitational forces?

>The Universe is expanding ever faster and faster according to recent studies. Eventualy it will cause an event called the "Big Rift".
How would Black Holes fair under the Big Rift? Would they survive due to their own gravitational forces?

There are approximately 400 billion stars in our galaxy, alone. If each of those stars has as many planets orbiting that star as our own sun, that's about 3.2 trillion planets in our galaxy.

Then, take a look at this picture.

Each of those lights is a galaxy in it's own.

It really makes you think; What am I worth? What is society in general worth? What will my mark be?

why is there matter? why does the universe exist?
