What we can observe in our Sky planets star gas does galaxy nebulary asteroids meet yours and more it is small fraction of what exist bright matter the visible stuff of the universe forms only about a 6th of its mass what form the rest and how do we know it's there
Scientist know their must be more out there that meet the eye because the unseen substances has gravity and appears to be holding together the parts of the universe that we can see Galaxy in particular because the unseen matter does not emitradiation scientist call it dark matter believe to constituent about 95% of the universe total mass dark matter and dark energy Mein compromise unfaiteronable number of time is sub atomic particle candidate for dark matter include cool dark matter CDM luggage elementary particle weekly interacting massive particle heavy particle that really interact with each other matter and masses compact hello object non objects such as planet neutron star and white dwarf that are free some to be in the Hallow of Galaxy
What is a black hole a black hole form when a large dying star collapses the gravity create by it condensing matter completely over power and outward force including light all the black hole in its no light it presence is detect able by radio astronomy equipment its extremely strong gravitational pull sucks gas and US towards it forming a drilling assertion disc around the whole the disc heat any matter that cross crosses it a meeting X rays what is a warm hole a highly spectaculative idea of modern Aster physics warmhole or theoretical possibilities allowed within the mathematical framework of Einstein general theory of relativity a warmhole is a shortly portal lasting only a brief movement that joins to black hole in different locations in the present day Universe perhaps in different time in one whole theory matter falling into a black hole at any one point should a proposed white hole the rivers of Black Hole at the others of them has get observed scientist cannot determine how it would be created all the Aster for this is such as Hawking continue to work on the integral notion Travellers School go from point two point in time or space through warm hole as imagine there in glowing purple
Fast fact the largest black hole on record waves as much as 40 billions and is orbited by another small black hole black hole extremely dense object of such strong gravitational force that nothing passing with a Creek certain distance can accept escape not even light dark matter unknown substan detected only by the gravity it ex make up most of the universe total mass
Stephen Hawkins so who was the Stephen Hawkins Stephen Hawking were was an astrophysis visionary approximately enough British theoretical physicist Stephen doubly Hawkins was born on the 300 anniversary of the death of Galileo since 1979 Hawking has held the chair in mathematics at Cambridge University once held by exact Newton Hawking study basic questions of the origin nature and future of the universe and he think a unified theory able to recognise Einstein general theory of relativity and Quantum theory
