Astronomical distances are difficult to fathom really... Common distances: http://csep10.phys.utk.edu/astrl62/lect/distances/distscales.html The fact that objects are light years away and we're seeing objects that no longer exist; stars have come and gone and we're seeing the long distant past in the present. In near space it's easier to comprehend distance; we've sent landing craft to the moon and Mars, hence solar system distances are comprehensible. Here is a fun calculator that allows you to calculate travel time to objects in space using different speeds: https://janus.astro.umd.edu/astro/distance/Use the maximum speeds of transport provided below and the time travel calculator determine the travel time to the objects listed in the table. What does this suggest about our ability to visit objects outside of our own solar system? How do these vast distances influence our ability to develop the evolutionary history of the universe and the evolutionary history of observable objects within the universe? The techniques and objects used to measure distances in space varying with the distance you are trying to measure - the series of methods used with distance is referred to as the astronomical distance ladder (see below) and includes the following observational tools: Cepheid variables Gravitationally Lensed Quasars Hubble constant and red shift Stellar parallax Supernovae Tully - Fisher relation

Explanation / Answer

Thurst SSC:

pluto distace from earth= 4.67billion miles= 4.67*10^9 miles

speed=771mph

total time taken= .006*10^9hrs

milkyway distance from earth= 10^18km

time taken= 10^18/1241.31km/hr =.805*10^15hr

edge of universe distance from earth= 4.40*10^23km

time taken=4.40*10^23/1241.31=.0035*10^23hr

fastest jet:

for pluto, time taken=4.67*10^9 miles/4520mph=.0010*10^9hrs

for milkyway time taken=10^18km/7274kmh=.137*10^15hrs

for edge of universe time taken=4.40*10^23km/7274kmh=.0060*10^23hr

for fastest spacecraft:

for pluto, time taken=4.67*10^9 miles/36000mph=.000129*10^9hrs

for milkyway time taken=10^18km/57924kmh=.017*10^15hrs

for edge of universe time taken=4.40*10^23km/57924kmh=7.5*10^18hr

Light beam:

for pluto, time taken=4.67*10^9 miles/186282mps=2.5*10^4sec

for milkyway time taken=10^18km/299792kms=3.3*10^12sec

for edge of universe time taken=4.40*10^23km/299792kms=1.46*10^18sec

It seems light's speed is the biggest challenges for other fastest equipments made by human being. Butt moving with light's speed means the spacecraft have no mass or ignorable mass therefore this hypothetical speed for spacecraft is still a part of huge imagination. The electromagnetic radiation and garvity field of earth are other important factors for spacecraft with the problem of moving large distances. Again from warm hole concepts the time and space factors are other troubles ahead.
