SUMMARY

The discussion centers on the complex relationship between time, light, and our perception of the universe, referencing Stephen Hawking's theories. Participants explore the concept of viewing stars as looking back in time due to the light's travel time. The conversation highlights the distinction between "zero time," where everything is static, and "regular time," where movement and perception are intertwined with the past. The overarching conclusion is that our understanding of time and space is limited, emphasizing the infinite nature of the universe.

PREREQUISITES
  • Understanding of basic astrophysics concepts
  • Familiarity with the speed of light and its implications
  • Knowledge of Stephen Hawking's theories on time and space
  • Basic grasp of the concept of relativity
NEXT STEPS
  • Research the implications of light travel time in astronomy
  • Study Stephen Hawking's theories on black holes and time
  • Explore the concept of spacetime in Einstein's theory of relativity
  • Investigate the philosophical implications of time perception in physics
USEFUL FOR

Anyone interested in astrophysics, philosophy of time, or the fundamental principles of light and perception, including students, educators, and science enthusiasts.

Ok please pardon my English and grammar. as its 1 of the subjects i did most poorly at

i would like to start on a topic that has led me to be soo confused and troubled
ive seen and read some of Stevens hawking books. and as it was quoted
to by some physics professor that looking at the stars was like looking back into the past
because of the time that the light takes to travel into Ur eye..
well ok at this point i understand the theory.
but what dose it acctually mean by the past?

If i could state some rules to apply to my general measurement.
lets say. i stopped time. just to view every thing around us. as far as u could imagin.
at this moment. there is no past and no future. every thing is at hault.
and u would travle to the most distant planet away from where ever u are and it would not be what u would have seen from a telescope. because viewing from a telescope with the regular rules in this world. would have mean as i said looking back to the past.!
and so this is where my mind gets realie confused.

1. Zero time . every thing has stopped moving. and u have the power of being any where in the glaxy u wana be.

2.regular time. every thing has been moving how the world would be and with you eyes through the worlds best telescope you would be looking at the past.

Amazingly some times what u see is not what u get.

Past or future. is somthing i do not understand.
but what i have come to realize is that we know soo little of what is there to be known.

thanks for reading.
i hope to hear some feedback soon.
sorry for my english and ect.

Very true.

As the universe is infinite, there is no way to know everything about everything.
